Organelles & Functions

Question 1

List the Nine Organelles

Answer 1

Nucleus
Plasma membrane
Mitochondria
Golgi apparatus
Endoplasmic reticulum
Ribosomes
Cytoskeleton
Cytoplasm
Lysosomes

Question 2

What’s the function of the nucleus

Answer 2

Contains our genetic information, DNA and RNA and controlls cellular activity by directing protein synthesis.

Question 3

What’s the function of the plasma membrane?

Answer 3

Controls the entry and exit substances in the cell

Question 4

What’s the function of the mitochondria?

Answer 4

Generates ATP via cellular respiration.

Question 5

What’s the function of the Golgi apparatus?

Answer 5

Modifies and packages, proteins and lipids synthesised by the endoplasmic reticulum ready to be delivered to their final destination.

Question 6

What’s the function of the endoplasmic reticulum?

Answer 6

Smooth, lacks ribosomes, and synthesises, lipids and dioxifies drugs.
Rough has ribosomes synthesises protein via mRNA translation.

Question 7

What’s the function of ribosomes?

Answer 7

Reads genetic information contained in the mRNA and assembles amino acids into chains synthesising proteins.

Question 8

What’s the function of the cytoplasm?

Answer 8

It’s a gel like substance that fills the cell acting as scaffolding for organelles

Question 9

What’s the function of the cytoskeleton?

Answer 9

Made up of a network of filaments, it’s involved in cell division, intracellular, transport, and cellular movement.

Question 10

What’s the function of lysosomes?

Answer 10

Contains a digestive enzyme that breaks down proteins, lipids and carbohydrates and is also involved in the removal of waste products and foreign particles.

Question 11

How many cells are in your body?

Answer 11

Around 100 trillion

Question 12

What is a cell?

Answer 12

The basic unit of life.
