What is a cell wall?
What type of cell is it?
This is a bow with holes in it that supports the cell. It is made of cellulose, Which is very strong.
It is a plant cell
What is chloroplast?
What type of cell is it?
These are green discs in the cytoplasm that contains chlorophyll. They make food for the plant, using photosynthesis.

What does ears do?
To hear
What do lungs do?

What does a blader do?
Stores urine
What does a large intestine do?
Removes water From unwonted food
What does a small intestine do?
Breaks up food and absorbs it, to provide nutrition for the body

Stem:Carries substances around the plant and supports the leaves and flowers
Leaf:Traps sunlight to make food for the plant
Roots:Holds the planting please. Roots also take water and small amounts of other substances from the soil
