Biology Organelle Functions

Question 1

This organelle is the control centre of the cell (surrounded by the nuclear membrane)

Answer 1

Nucleus

Question 2

This organelle is the fluid substance in a cell

It is where chemical reactions occur

Answer 2

Cytoplasm

Question 3

This organelle gives support to the cell

controls the movement of materials in and out of the
cell (semi-permeable)

Answer 3

The Cell Membrane

Question 4

role varies depending on type of cell

can be used for storage of food, removing waste,
maintaining fluid pressure, etc.

Answer 4

Vacuoles

Question 5

This organelle Contains the green pigment chlorophyll, used in photosynthesis

Answer 5

Chloroplasts

Question 6

This organelle protects and supports the plant cell

Answer 6

Cell Wall

Question 7

“power plants” of the cell

it produces energy for cell functions

active cells have many mitochondria while inactive
cells have fewer

Answer 7

Mitochondria

Question 8

Is the network of branching tubes attached to the nucleus.

• A passageway for materials moving to and from
  different parts of the cell
• Site of protein synthesis (after code from nucleus’
  DNA is read)

Answer 8

The Endoplasmic Reticulum

Question 9

This organelle is NOT attached to nucleus

• It collects and processes materials to be removed
  from/used by the cell
• It Modifies proteins that come from the E.R.’s ribosomes
• And the Proteins’ shapes affect their function!

Answer 9

Golgi Bodies

Question 10

This organelle makes protein and is found attached to the E.R. or free floating in the
cytoplasm.

Answer 10

Ribosomes
