Controlled variable definition
how much sun the tree gets
An organelle found in plant cells that stores mainly water this helps create pressure that inflates the cell.
A rigid layer of cellulose outside the cell membrane, that gives the plant and the cell, structure, and support.
Dependent variable definition
A process that plants use to convert the sun's energy into sugars that the plant can use.
The amount of water the the tree receives
Organelles only found in animal cells that break down and digest food particles and worn out cell parts.
A green pigment found in chloroplasts that help trap the sun's energy.
An organelle found in eukaryotic cells that store food, water and waste.
Material that makes up the cell wall of a plant cell.
Independent variable definition
An organelle found in plant cells that capture the sun's energy and convert the light energy into chemical energy.
Organelles found in animal cells that store food, water and waste.
