1
Q

What is a eukaryotic cell?

A

Animal and plant cells, inc. fungi and algae.

2
Q

What is the structure of a eukaryotic cell?

A

1) . Plasma membrane (cell surface).
2) . Nucleus.
3) . Endoplasmic reticulum.
4) . Ribosomes.
5) . Lysosomes.
6) . Golgi body.
7) . Mitochondria.

3
Q

What is the plasma membrane?

A

Found on the surface of animal cells.

4
Q

What is the plasmic membrane made up of?

A

Lipids and proteins.

5
Q

What is the function of plasma membrane?

A

Regulates the movement of substances into and out of cells (manufacture and transport).

6
Q

What is the nucleus?

A

Found in the middle of a cell.

7
Q

What does the nucleus contain?

A

Chromosomes (containing DNA).

8
Q

What is the function of the nucleus?

A

Controls the cells activities.

9
Q

What is the mitochondria?

A

Oval-shaped organelle.

10
Q

What is the function of the mitochondria?

A

Energy is extracted from food through metabolism.

11
Q

What is the rough endoplasmic reticulum?

A

Membranes enclosing a fluid-filled space.

12
Q

What is the function of the rough endoplasmic reticulum?

A

Folds and processes proteins that have been made at the ribosomes (packaging and processing).

13
Q

What is a ribosome?

A

Organelle that floats in the cytoplasm, or is attached to the rough endoplasmic reticulum.

14
Q

What is the function of a ribosome?

A

Production of proteins.

15
Q

What is a lysosome?

A

Round organelle, a type of golgi vesicle.

16
Q

What is the function of a lysosome?

A

Digest/break down invading cells (breakdown of chemicals and bacteria).

17
Q

What is a golgi apparatus?

A

A group of fluid-filled flattened sacs.

18
Q

What is the function of a golgi apparatus?

A

Processes and packages new lipids and proteins.

  • Makes lysosomes.
