Document Summary
Importance of plants: characteristics of plants, major types of plants. What is a plant: usually green, typically does not consume other organisms, grows but does not move from place to place. Scientific definition is more formal and not quite simple. Photosynthesis supports us in three ways: oxygen, primary producers, building blocks of life. Photosynthesis uses light energy to convert co2 and h2o into sugars: chloroplasts - photosynthesis occurs in this location, typically around 3-5 m in diameter, could be circular or elongated, typical cell may contain between 5-50 chloroplasts. Plant cell and animal cells are the same except for 3 main things: plant cells have, a cell wall, plastids, a large vacuole. To look at the ultrastructure of a cell, an electron microscope must be used. An adult plant cell has a large vacuole filling up 90% of its space. Stroma - fluid compartment of chloroplast: thylakoids - disc-shaped membrane sacs, granum - stacks of thylakoids.
