Parts of Plants Each part of a plant has a very important function. All plants produce flowers for the same reason: to make seeds so another plant can grow. Leaves: These are the parts of the plant where food is made by photosynthesis. Leaves take in carbon dioxide from the air, water from the soil, and energy from the sunlight. Flowers: These are the reproductive parts of a plant. Stems: These support the upper parts of plants. Roots: These anchor plants in the soil. Seeds: these contain a tiny embryo of a plant inside. Flower Anatomy Printout EnchantedLearning.comFlower Anatomy The Flower: The flower is the reproductive unit of some plants (angiosperms). Parts of the flower include petals, sepals, one or more carpels (the female reproductive organs), and stamens (the male reproductive organs). The Female Reproductive Organs: The pistil is the collective term for the carpel(s). Each carpel includes an ovary (where the ovules are produced; ovules are the female reproductive cells, the eggs), a style (a tube on top of the ovary), and a stigma (which receives the pollen during fertilization). The Male Reproductive Organs:Stamens are the male reproductive parts of flowers. Fertilization: Pollen must fertilize an ovule to produce a viable seed. Types of Flowers: Some flowers (called perfect flowers) have both male and female reproductive organs; some flowers (called imperfect flowers) have only male reproductive organs or only female reproductive organs.
Life Science | Session 1 Boy with "green stuff" Learning Goals During this session, you will have an opportunity to build understandings to help you: Distinguish between living, dead, and nonliving Define the characteristics of life Video Overview What is life? Video Outline We open with a look at environments where you wouldn’t expect to find life and pose this question: "If you are looking for life, what do you look for?" The program continues as children in grades two and three are presented with a challenge: group objects as living, dead, or nonliving. In Brooklyn, New York, we visit LauraJo Kelly and her second-grade students as they generate their own definitions of living, dead, and nonliving and proceed to design experiments to test whether a “mysterious” object is alive. Our search for an answer to the question "What is life?" Finally, Dr.
Fighting Carbon with Fire Fire has been used by Bininj (aboriginal) people for managing habitats and food resources across northern Australian over millennia. The secret of fire in our traditional knowledge is that it is a thing that brings the land alive again. So we don’t necessarily see fire as bad and destructive — it can be a good thing. Unfortunately, today fire is not being well looked after in many places in Northern Australia. However, it continues to be managed well around the outstations where people live all the time, such as at Kabulwarnamyo, where I live. As a Bininj man from Nangark of the Gurrguni clan, I hold much knowledge regarding my people’s traditional use of fire and have a great responsibility to ensure that this knowledge is passed down to younger generations, and more importantly, that this knowledge is still used and practised into the future to keep our country alive and healthy. Bininj perspective on climate change Our people have lived through periods of great change. Sea level rise
Great Vegetable Seeds from The Real Seed Catalogue Cell Models: An Interactive Animation Nucleolus: The prominent structure in the nucleus is the nucleolus. The nucleolus produces ribosomes, which move out of the nucleus and take positions on the rough endoplasmic reticulum where they are critical in protein synthesis. Cytosol: The cytosol is the "soup" within which all the other cell organelles reside and where most of the cellular metabolism occurs. Though mostly water, the cytosol is full of proteins that control cell metabolism including signal transduction pathways, glycolysis, intracellular receptors, and transcription factors. Cytoplasm: This is a collective term for the cytosol plus the organelles suspended within the cytosol. Centrosome: The centrosome, or MICROTUBULE ORGANIZING CENTER (MTOC), is an area in the cell where microtubules are produced. During animal cell division, the centrioles replicate (make new copies) and the centrosome divides. Centriole (animal cells only): Each centriole is a ring of nine groups of fused microtubules.
Experimentskafferiet Carbon 101 How to start plants from seed indoors to transplant in the garden later Andrea Levy, The PD With visions of plump, juicy tomatoes, crisp cauliflower and sunny marigolds dancing in their heads, some gardeners spend late winter sowing seeds indoors and pampering their emerging beauties until it's warm enough to move them outdoors. These indoor gardeners like to get growing early for several reasons. One, a packet of a dozen or so seeds, which costs a few dollars, is a fraction of what ready-to-plant botanicals cost. "It's cheaper than buying flowering plants and vegetable starts," says Christine Harris, an Ohio State University Extension Cuyahoga County master gardener, who won the statewide award of volunteer of the year at the International Master Gardener Conference in Charleston, W.V., last year. Harris, who has been starting seeds indoors for about 13 years, says she has discovered a lot of vegetables and flowers that are not available at local greenhouses. And finally, it's entertaining for kids. "It's important to follow the instructions," he says. 1. 2.
The way of the dragon: chemistry for the youngest By Anna Gunnarsson What makes a good Berta activity? All the Berta activities have been tried out with young children many times over several years to ensure that they are interesting and easy to do. In this article we describe three popular activities that are typical of Berta’s style. About what happens When water is added, the sodium hydrogen carbonate and citric acid dissolve in it and start reacting. Carbon dioxide gas is denser than the surrounding air so it doesn’t all float away, but there is still a chance of it escaping due to turbulence in the air (and it’s really hard to see where it goes as it has no colour). Activity 2: Taking citrus fruits for a swim Age-group: 4-8 years Activity 3: Droplet drama Materials References Gunnarsson A., Södergren K.

Plant Cell Vs. Animal Cell The bodies of both plants and animals are made up of cells. Although the basic structure and most of the features are the same, there are many points of differences between the two. The primary differences between both cells arise because of the fact that plants have to produce their own food by photosynthesis. The various structures within a cell are called organelles. Plant Cell Vs. Cell Type Both plant and animal cells are eukaryotic in nature, having a well-defined membrane-bound nucleus. Nucleus It is present in both. Cell Membrane It is a semi-permeable or selectively-permeable membrane that encloses the contents of a cell, allowing only selected molecules to enter the cell and blocking the others. Mitochondria They act as the powerhouse of the cell, converting food into energy. Endoplasmic Reticulum (ER) These membrane-bound organelles consist of a series of sac-like structures that help in the production of proteins and lipids, and transport to the Golgi apparatus.
