Unit 2: Living Organisms And Cells

Question 0

What properties does a plant cell have?

Answer 0

Cell wall: outside skin. Covers cell membrane. Made of tough cello use which strengthens the cell.m
Cell membrane: thick skin on outer layers. Is a thin skin around cell. Gives cell it’s shape and controls what goes in and put.
Chloroplasts: green big dots. found in cell that carry out photosynthesis. Contain chlorophyll to trap light energy.
Cytoplasm: bigger dots. Often contain starch grains.
Mitochondria: big black dots. Where cellular respiration takes place.
Vacuole: big space in the middle. Plant cell has large permanent vacuole filled with liquid called cell sap.
Nucleus: dot in the middle. Controls what the cell does contains instructions to make new cells.
