draw up water from the water and minerals from the soil and also stores food for plants
root plants (examples)
potatoes, beets, radishes, sweet potato, carrots, turnups and other plants you find in the grounds
one large root with a few hairy branching roots- grow deep into the ground and reach water deep down
can make huge networks; spread out near the soil's surface; thin and hairy
roots that never touch the grounds ; plants like orchids ( take moisture from the air because their roots never touch the ground)
corn plants have them; look like fingers sticking out (they help prop up the plant) page 21
how are stems similar?
All stems support leaves 2. stems also hold the transportation system for plants (where water and minerals move from the roots to all parts of the plant)
Leaves with a single blade (maple and oak)
leaves that come in clusters (chesnut and locust)
outer layer of leaves
covered with a waxy coating called a cuticle. you can touch this layer
what does a leaf do for a plant?
making food for storage; regulate water loss; and helps support a plant
what makes orchid different?
some dangle in the air, some wrap around a tree branch, some green make food absorb the water and minerals- some roots are very flat and long
the small openings on the undersides of most leaves through which oxygen and carbon dioxide can move
food making process for plants; means putting together by light.
steps of photosynthesis
1. sunlight strikes a green part of the plant (like a leaf) 2. chlorophyll helps make the plant's food. chlorophyll is found in chloroplasts that act like tiny factories 3. inside them water and carbon dioxide from the air combine to make sugar and oxygen. The sugars help the leaf to make them go into the leaf's veins and off to parts of the plant 4. the oxygen the plant makes goes out into the air. all animals need this to breathe. animals breathe out carbon dioxide that help plants survive
the energy released when the sugars break apart
how do leaves change color?
when the temperature begins to drop, the leaves stop making chlorophyll. Yellow and orange appears... red later
