Cell Parts

Question 1

Nucleus

Answer 1

Is the control centre containing all the genetic information for the cell which controls all cell activities

Question 2

Cytoplasm

Answer 2

Contains a soup of chemicals in which the reactions occur. The cytoplasm gives the cell shape

Question 3

Cell Membrane

Answer 3

Forming the outside of the cell acts as a barrier and controls the transfer of materials into and out of the
cell

Question 4

Small vacuoles (vesicles)

Answer 4

Store food and chemicals and floating in the cytoplasm. Animal cells have many small vacuoles whereas plant cells have a large central vacuole

Question 5

Mitochondria

Answer 5

Is the place in which the cell converts food into energy (called respiration). Many animal cells, eg. muscle cells and nerve cells, have a lot of mitochondria because they use more energy.

Question 6

Endoplasmic reticulum

Answer 6

Transport system inside the cell

Question 7

Ribosomes

Answer 7

Site of protein production. Most cell (and body structures) are made of protein

Question 8

Golgi apparatus

Answer 8

Package and release proteins from the cell

Question 9

Cell wall

Answer 9

Made of fibres of cellulose that gives them shape and strength. The cell wall fits closely just outside the cell membrane

Question 10

Chloroplasts

Answer 10

Small round green organelles called, which contain the green pigment chlorophyll, photosynthesis occurs in the chloroplasts where plants make glucose sugar from light, carbon dioxide and water. Chloroplasts are usually on the outside of the cell so they are close to light and the raw materials they need.

Question 11

Large Vacuoles

Answer 11

Store food and chemicals and floating in the cytoplasm. Plant cells have a large central vacuole where as animal cells have many small vacuoles because plants make food during the day by photosynthesis. This needs to be stored. The vacuole also gives extra support to the cell by pressing hard against the cell wall.
