Cells and organelles

Question 1

What is the function of the organelle cytoskeleton

Answer 1

Provides structural support of the cell

Question 2

What influence does the organelle cytoskeleton have on the cell

Answer 2

Because it provides the cell with structural support it influences:
1. The strength
2. The shape
3. The flexibility
4. The movement of the cell

Question 3

What is the organelle cytoskeleton made up of

Answer 3

It is made up of various proteins such as actin and tubulin.

Question 4

Make an example of cells that have extracellular structures built around the core of cytoskeleton

Answer 4

Flagellum and Cilia

Question 5

What are ribosomes

Answer 5

They are small organelles mase up of large and small subunits which come together for protein synthesis.

Question 6

What is the role of ribosomes

Answer 6

They translate mRNA into proteins.

Question 7

Where are ribosomes located in a cell

Answer 7

1. They float freely in the cytoplasm and synthesis protein for the cytosol. Called free ribosomes.
2. They can be attached to the rough endoplasmic reticulum and products are secreted outside the cell.

Question 8

What is the role of the endoplasmic reticulum

Answer 8

(a) synthesise and store proteins, carbohydrates and lipids, and transport molecules within its enclosure
(b) detoxification of dangerous material

Question 9

what is endoplasmic reticulum made of

Answer 9

Made up of series of tubes and chambers (cistarnae) and connected to the mebrane that surrounds the nucleus (nuclear envelope)

Question 10

What are the two types of endoplasmic reticulum

Answer 10

Rough and Smooth.

Question 11

What is the function of the rough endoplasmic reticulum

Answer 11

I. receives newly manufactured proteins from ribosomes
II. modifies proteins into glycoproteins
III. Packages proteins and glycoproteins into vesicles to be sent to the Golgi apparatus
