Module 1 - 1.1.1 Cell Structure

Question 1

What are Eukaryotic Cells?

Answer 1

Complex cells such as animal and plant cells. They have an organised nucleus with a nuclear envelope. The also have components that make the cell a self sufficient organism.

Question 2

What are Prokaryotic Cells?

Answer 2

Small, simple cells like bacteria that don’t have an organised nucleus.

Question 3

What is the function of a ribosome?

Answer 3

The site where proteins are made.

Question 4

What is a Lysosome?

Answer 4

A round organelle which is surrounded by a membrane. It contains digestive enzymes. This can be used to digest invading cellsor tobreak down worn out components.

Question 5

Explain the Sturcture of Mitochondria.

Answer 5

• Mitochondria are made of two membranes. The outer membrane contains the organelle like skin and the inner membrane folds over and makes layered structures called cristae.
• Fluid inside the structure is called the matrix. This is where the Mitochodrion’s DNA and ribosomes float.
• There are also structures called granules which control the concentrations of ions.
