List the components of both plant and animal cells (5)

• Nucleus

• Cytoplasm

• Cell membrane

• Mitochondria

• Ribosomes

List the additional cell components found in plant cells (3)

• Chloroplasts

• Permanent vacuole

• Cell wall

Other than storing genetic information, what is the function of the nucleus?

Controls cellular activities

Describe the structure of the cytoplasm.

• Fluid component of the cell.

• Contains organelles, enzymes and dissolved ions & nutrients.

What is the function of the cytoplasm?

• Site of cellular reactions e.g. first stage of respiration

• Transport medium

What is the function of the cell membrane?

Controls the entry and exit of materials into and out of the cell.

What is the function of the mitochondria?

Site of later stages of aerobic respiration in which ATP is produced.

What is the function of the ribosomes?

Joins amino acids in a specific order during translation for the synthesis of proteins.

What is the plant cell wall made of?

cellulose

What is the function of the plant cell wall?

• Provides strength

• Prevents the cell bursting when water enters by osmosis

What does the permanent vacuole contain?

Cell sap (a solution of salts, sugars, and organic acids)

What is the function of the permanent vacuole?

Supports the cell, maintaining its turgidity.

What is the function of chloroplasts?

Site of photosynthesis
