Native Plant Society of Texas. Flora of North America. Top 10 Most Dangerous Plants in the World. 1. Most likely to eat a rat Giant Pitcher Plant: Nepenthes attenboroughii Discovered more than 5000 feet above sea level on Mount Victoria in the Philippines, the giant, carnivorous pitcher plant secretes a nectar-like substance to lure unsuspecting prey into a pool of enzymes and acid.
A series of sticky, downward ribs makes it nearly impossible for trapped prey to escape. 2. Castor Bean Plant: Ricinus communis Castor-bean plants can be purchased at just about any garden center, despite containing the deadly poison ricin. 3. Western Water Hemlock: Cicuta douglasii Deemed the most "violently toxic plant that grows in North America" by the USDA, the water hemlock contains the toxin cicutoxin, which wreaks havoc on the central nervous system, causing grand mal seizures--which include loss of consciousness and violent muscle contractions--and eventually death, if ingested. 4. White snakeroot: Eupatorium rugosum 5. Monkshood: Aconitum napellus 6. Common Bladderwort: Utricularia macrorhiza 7. 8.
Monocots vs. Dicots. Having taught in introductory botany for more than five years, I have fielded many questions from students, and present below some of the more common questions and misconceptions. Thanks go to my students for taking an active role in their own education, and asking these questions Q: Are pine trees monocots or dicots?
A: Pines are conifers, and are neither monocots nor dicots. Only flowering plants are considered to be members of these two classes. This question is similar to asking whether a chicken is a monocot or a dicot; it is neither. Q: Do all dicots produce flowers? A: Yes, sort of. There are also some flowering plants which flower only rarely. Q: If monocots don't have wood, then what supports palm trees? A: Palms rely on overlapping leaf bases, thickened enlarged cells, and prop roots to stay up. Welcome - Science & Plants for Schools. Welcome to the PLANTS Database | USDA PLANTS.
