Ribosomes function

protein synthesis (makes proteins)

Nucleus function

controls the functions of the cell

What does the nucleus contain?

DNA

What happens in the cytoplasm

most chemical reactions

Mitochondria function

aerobic respiration; release energy

where are ribosomes found

Rough endoplasmic reticulum or in the cytoplasm

Cell wall function

provides the cell structural support

what is cell wall made of

tough carbohydrate called cellulose

permanent Vacuole function

store cell sap

what is cell sap a store of?

dissolved sugars, mineral ions, and other solutes

what does Chloroplast contain for its function?

contains green pigments called chlorophyll, which absorb light energy.

chloroplast function

Photosynthesis (produces glucose for respiration)

why do plants need energy?

moving water and minerals, repairing damaged cells, growing new leaves or roots, etc
