KS3 Year 7 Biology Cell structures

Cell membrane

• Made of a tough substance called cellulose, which supports the cell
• Carries genetic information and controls what happens inside the cell
• Absorbs the sun’s energy to help make glucose for the plant (photosynthesis)
• Controls the movement of substances into and out of the cell

Cytoplasm

• Absorbs the sun’s energy to help make glucose for the plant (photosynthesis)
• Controls the movement of substances into and out of the cell
• Jelly-like substance, where chemical reactions happen
• Carries genetic information and controls what happens inside the cell

Nucleus

• Where most respiration reactions happen
• Absorbs the sun’s energy to help make glucose for the plant (photosynthesis)
• Controls the movement of substances into and out of the cell
• Carries genetic information and controls what happens inside the cell

Mitochondria

• Absorbs the sun’s energy to help make glucose for the plant (photosynthesis)
• Carries genetic information and controls what happens inside the cell
• Where most respiration reactions happen
• Made of a tough substance called cellulose, which supports the cell

Vacuole

• Carries genetic information and controls what happens inside the cell
• Contains a liquid called cell sap, which keeps the cell firm
• Controls the movement of substances into and out of the cell
• Made of a tough substance called cellulose, which supports the cell

Cell wall

• Jelly-like substance, where chemical reactions happen

• Made of a tough substance called cellulose, which supports the cell

• Carries genetic information and controls what happens inside the cell

• Controls the movement of substances into and out of the cell

Chloroplast

• Absorbs the sun’s energy to help make glucose for the plant (photosynthesis)

• Contains a liquid called cell sap, which keeps the cell firm

• Controls the movement of substances into and out of the cell

• Jelly-like substance, where chemical reactions happen
