Orchids. Botany Photo of the Day. Taisha wrote today's entry. We were both challenged to find the bona fide botanical name for this taxon, and had to give up (no results in the USPTO database, for one), so we left it as a black-fruited selection (read more below). Taisha writes: The past two days in Vancouver have been quite warm and enjoyably sunny--prompting many to get out into the garden. Some have begun planting seeds indoors or in greenhouses, and it won't be long until we can directly seed outdoors. Today, we have a photo of some caryopses of Zea mays. For those in the temperate northern hemisphere who are anticipating growing plants from seeds soon, I thought I would help explain some oft-used seed terminology. Certified organic (with an emphasis on Canada, as definitions and regulations are different depending on country): Organic seeds are seeds that are harvested from a plant grown in a way that meets organic regulations.

10 Creepy Plants That Shouldn't Exist. We spend a lot of time here at Cracked pointing out horrors of nature that slither on the land and lurch through the sea. But staying under the radar in nature's landscape of nightmares is the twisted carnival of things that grow out of the ground. Like ... Bleeding Tooth Fungus The bleeding tooth fungus looks kind of like a wad of chewing gum that leaks blood like a rejected prop from The Shining. They're also called the strawberries and cream, the red-juice tooth, and the devil's tooth. Oh, and they are listed as "inedible," which implies that someone attempted to eat one at some point.
Chinese Black Batflowers There's a good reason that Batman uses bat imagery to strike terror into the hearts of Gotham's criminals, rather than, say, some kind of shrew. It is kept as an ornamental plant by gardeners who prefer to cultivate nightmares, and have the balls to live in the presence of a plant that looks like it crawled out of a Bosch painting and wants to plant its young in their head.
Rare Plants | It's a Wonderful World. 神秘果 Miracle Fruit (Synsepalum Dulcificum)Although not sweet itself, if consumed fresh and allowed to coat your mouth, this miraculous fruit alters your tastebuds so that everything you eat tastes sweet with effect lasting one to two hours. The beauty of it is that it only removes the acidic sourness (such as lemon) from what you are eating. The natural aroma and taste remains. It has been used to sweeten bitter medicines. You should eat the berries immediately on picking. If they are stored in the refrigerator for a day or so, they often lose their effectiveness in changing the tastebuds.
神秘果尝后能暂时改变人的味觉系统，即使再吃酸味水果亦呈甜味。 舞草 Telegraph Plant (Desmodium Gyrans) The plant is also known as the Dancing Plant or the Curiosity Plant. Charles Darwin once wrote in his book,"The little leaflets never go to sleep, and this seems to me very odd… They are at their games of play as late as 11 o’clock at night and probably later.

Plant perception (physiology) In the study of plant physiology Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. Closely related fields include plant morphology , plant ecology , phytochemistry , cell biology, and molecular biology.Fundamental processes such as photosynthesis, respiration, plant nutrition,... plant perception is a term used to describe mechanisms by which plants recognize changes in the environment.
Examples of stimuli which plants perceive and can react to include chemicals, gravity, light Light or visible light is electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. Visible light has wavelength in a range from about 380 nanometres to about 740 nm, with a frequency range of about 405 THz to 790 THz... , moisture Humidity is the amount of moisture the air can hold before it rains. , infection An infection is the colonization of a host organism by parasite species.

Dr. Pradit Kampermpool marches through his plant nursery, past row upon row of exotic orchids, before stopping, his chest proudly puffed out, in front of an unremarkable, weedy-looking plant. This plant, he says gravely, cost him a fortune. He developed complicated breeding programs and followed them religiously for almost 10 years to produce it, he says. This plant, he says, is a dancing plant. He pauses for effect. Meanwhile, the sun comes up over the green fields. Kampermpool stands maybe 5 and a half feet tall. It is almost 6:30 in the morning and we are standing in Kampermpool’s plant nursery in Udon Thani Province, in tropical northern Thailand.
At night, elephant handlers — bent, little toothless mahouts — park their elephants implausibly under the store awnings downtown, to shelter from the rain that comes nightly. The dancing plant grows unchecked in a secluded enclosure at the back of Kampermpool’s nursery, bursting from a brick trough filled with dark wet soil.
It was 1976. Psychobotany. Cleve Backster (b. 1924) is a polygraph scientist best known for his discovery of "primary perception" stemming from his experiments in biocommunication with plant and animal cells. Prior to his founding of The Backster Research Foundation, Inc. in 1965, Mr. Backster was Chairman of the Research and instrument Committee of the Academy for Scientific Interrogation, a post to which he was reappointed for eight consecutive years. During his intensified research activity, which started in 1958, he consolidated, refined and expanded upon the then existing polygraph techniques.
This effort resulted in the development of the "Backster Zone Comparison Technique" and the first system for the numerical evaluation of polygraph charts. These developments have been generally adopted as the standard throughout the polygraph field and have been successfully employed by the Johns Hopkins University Applied Physics Lab in their ongoing research on computer assisted polygraph chart analysis.

Do plants have feelings? The amazing life of plants. The amazing and hidden life of plants Are plants intelligent? While visiting a friend in Australia many years ago, I was invited to see a large marijuana growing operation which used hydroponics and halogen lights. The garden was in a large room and the pants were arranged in neat rows. On one side of the room the plants seemed taller and fuller, gradually diminishing as they were positioned away from one particular corner.
I mentioned the obvious difference to the owner of the operation and he explained that the corner with the most productive plants was where he had his stereo. Curious, I asked him what kind of music the plants liked. According to the gardener, crickets usually chirp right before a rain. Can plants actually hear sound?
Backster decided on impulse to attach his polygraph electrodes to the now-famous dracaena in his office, then water the plant and see if the leaves responded. Nervous systems in plants? An Indian scientist, Dr. Dr. Plants with feelings? Sequoía sempervírens (D. Sequoia sempervirens (D. Don) Endl. Redwood Taxodiaceae -- Redwood family David F. Redwood (Sequoia sempervirens), also called coast redwood and California redwood, is native to the central and northern California coast, a region of moderate to heavy winter rain and summer fog so vital to this tree.
Habitat Native Range The range of redwood extends southward from two groves on the Chetco River in the extreme southwest corner of Oregon (lat. 42° 09' N.), to Salmon Creek Canyon in the Santa Lucia Mountains of southern Monterey County, CA (lat. 35° 41' N. . ) . - The native range of redwood. Climate The mild climate of the redwood forest region can be classed broadly as super-humid or humid.
Annual precipitation varies between 640 and 3100 mm (25 and 122 in) and is mostly winter rain, although snow sometimes covers the highest ridges. The frequent summer fogs that blanket the redwood region seem to be more significant than the amount of precipitation in delineating the redwood type. Life History. Sensitive Plant. Plants have life. They breathe, prepare food, grow and reproduce. There is one more characteristic of plants which can be clearly seen in some species and that is response to stimuli.
This characteristic is very prominent observed in a plant called sensitive plant. This plant is famous for its response to touch and has the tendency to close its leaves when someone touches it. This characteristic has given it many names like humble plant, shameful plant, touch me not, sleeping grass etc. So, let's find out some more interesting facts and characteristic of this unique plant. Classification and Description Scientific Name: Mimosa pudica Family: Leguminosae Common Name: Humble Plant, Shameful Plant, Touch Me Not, Sleeping Grass, Tickle-Me Plant Distribution: It originated in Brazil but has now spread to most of the states of America, Africa, Asia and the Gulf.
Description: Mimosa Pudica is among the 300 species found under mimosa, which belong to the Leguminosae family. How to Grow.

Presented as part of Lincoln Center Out of Doors, Homemade Instrument Day in New York, Pieces for Plants is an interactive sound installation for laptop, synthesizer, and the American semi-tropical climbing Philodendron.
Versions of the piece have also been presented in a musical setting in which the plant participates as a member and soloist within an instrumental ensemble. In the piece, a plant’s real-time responses to its physical environment are translated to sound. Highly sensitive electrodes are attached to the leaves of the plant. Scored movements by a human “plant player” stimulate physiological responses in the plant that are monitored via the electrodes and biofeedback wave analysis.

Plant hormones are known as phytohormones in botanical terms. Plant hormones are chemicals just like animal hormones that help in the growth, development and functioning of plants. Like animals, plants too are living organisms that function as a unit. They carry out vital biochemical reactions that are required to survive. These biochemical reactions require hormones also known as 'plant growth substances'. These hormones help in formation of leaves, flowers, stems, fruit, etc.
What are the Functions of Plant Hormones? List of Plant Hormones, Where They are Found and Their Functions in Plant Growth: Auxin This hormone is present in the seed embryo, young leaves and apical buds meristem. Function of Auxins: Cytokinin Cytokinins are synthesized in roots and then transported to other plant parts. Function of Cytokinins: Ethylene Ethylene is present in the tissues of ripening fruits, nodes of stems, senescent leaves and flowers. Function of Ethylene: Abscisic Acid Function of Abscisic Acid:
