1. Store it (as fats, carbohydrates, proteins) 2. Use it (for energy and materials for life)
How do plants (and other organizms) use food?
Through a process called CELLULAR RESPIRATION
What is needed for cellualr respiration?
1. Sugar (glucose) ??? 2. O2 (oxygen) ????
What is made by cellular respiration?
1. H2O (water) ???? 2. CO2 (carbon dioxide) and Chemical energy for life is released (not "made")
Here is a summary of cellular respiration
Sugar + Oxygen = Water + Carbon Dioxide+ Energy for life
Plant bodies have special structures to help them with photosynthesis and cellular respiration, These include:
1. Stomates 2. Xylem 3. Phloem 4. Roots 5. Chloroplasts 6. Mitochondria (these are in plants AND animals)
Stomates: What they do and where they are found
What do: Let CO2 in, let O2 and H2O out Where found: Mainly on leaves, they look like small mouths
Xylem: What it does and where found
What do: Carries H2O around the plant Where: Thin tube that runs through the plant from roots through stem to leaves
Phloem: What it does and where found
What do: Carries sugar Where: Thin tube that runs throughout the plant
Roots: What does and Where found
What do: Take in water and nutrients and attach plant to the ground Where: Underground
Chloroplasts: What is does and where found
What do: Photosynthesis happens here Where: In the cytoplasm of leaves and other green plant cells
Mitochondria (these are in plants AND animals)
What do: Cellular respiration happens here Where: All plant and animal cells
Energy from the sun causes water molecules to evaporate out of the stomate. As a water molecule leaves, it pulls on the molecule behind it. The pull continues all the way down the plant and into the the roots, bringing more water into the plant.
Transpiration: _____ from the sun causes water molecules to evaporate out of the ____________
The pull on water molecules in transpiration continues all the way down the plant and into the ____, bringing more water into the ______
Water molecules attract each other because they are______
have one positive side and one negative side
What surrounds the stomate?
Veins have what in them?
xylem and phloem
Leaf cells contain ______.
Chloroplasts have _____ to trap energy from the sun?
Chlorophyl traps _____ from the sun.
The trunk of the tree includes ____ & ____ to carry water and sugar/food
Xylem and phloem in a tree trunk carry _____ & ____
