What does energy do for plants?
energy fuels life processes and materials (molecules) to build and repair their bodies
Here is a summary of photosynthesis
Water (H2O) + Carbon dioxide (CO2) + Sunlight = Sugar + Oxygen (O2)
What do plants do with the food they make?
1. Store it (as fats, carbohydrates, proteins)
2. Use it (for energy and materials for life)
What is made by cellular respiration?
1. H2O (water)
???? 2. CO2 (carbon dioxide) and Chemical energy for life is released (not "made")
Plant bodies have special structures to help them with photosynthesis and cellular respiration, These include:
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
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.
_____ 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 ______
