1
Q

Unicellular organisms

A

Organisms made up of only one cell

2
Q

Multicellular organisms

A

Organisms made up of many cells (2 or more)

3
Q

Organelles

A

Organs inside the cell that have a specific job or function

4
Q

Nucleus

A

An organelle that controls all activities of the cell

Is the control centre of cell

5
Q

Cell membrane

A

In both plants and animal cells

The skin that holds everything together

6
Q

Cell wall

A

Only in plant cells

Gives cell structure to keep plant upright. Works as the Skeleton of the plant

7
Q

Cytoplasm

A

Watery, jelly like substance that contains many smaller parts

8
Q

Vacuole

A

In animal cells it contains the chemicals and waste

9
Q

Chloroplast

A

In plant cells and only in green parts of plants

Contains chlorophyll and is the site for photosynthesis

10
Q

Fungal cells

A

Same organelles as an animal cell plus a cell wall

Cell wall is made up of different material than plants

11
Q

How are plant cells different than animal cells

A

Plant cells have a cell wall and chloroplasts

12
Q

Do fungal cells have chloroplast

A

No, therefore they cannot make their own food

They create there own food by digesting material they are growing on

13
Q

Mitosis

A

Cell division that produces two identical cells

14
Q

Uni and multicellular mitosis

A

Uni- mitosis used for reproduction

Multi- mitosis used for repair and growth

15
Q

Bacteria

A

Example of unicellular organism

From monera kingdom

Some bacteria causes disease and infection while some help you stay healthy

16
Q

What doesn’t a unicellular organism have

A

A nucleus or any organelles

17
Q

Cell theory

A

All living things are made up of one or more cells

Cells are the basic building blocks for all living things

New cells are produced from existing cells

18
Q

Mitochondria

A

The powerhouse of the cell that releases energy from food
