Name the 4 Eukaryotic cells.

Animal, Plant, Fungi, Protoctists

Name a Prokaryotic Cell.

Bacteria

What makes a cell Eukaryotic?

DNA is in form on chromosomes, DNA found in the nucleus.

What makes a cell Prokaryotic?

Don’t have a nucleus, DNA loose in cell.

10 - 100 X smaller than eukaryotic

What do animals have in common?

Multicellular (made up of lots of cells rather than 1)

Heterotrophs (get energy from other organisms, food)

Most reproduce sexually

What do plants have in common?

Multicellular

Autotrophs (Get energy from sun using photosynthesis)

How is fungi different to plants?

It can’t photosynthesise.

What nutrition does fungi use?

Saprophytic

What is saprophytic nutrition process?

1. Secrete digestive enzymes onto food outside their body

2. Enzymes break down the food

3. Absorb all the nutrients

What do protoctists have in common?

Unicellular (1 cell)

What do bacteria have in common?

Single-celled organisms

No chloroplasts

Most feed off other organisms

Help to digest food

What creates salmonella

Bacteria

What creates athletes foot?

Fungi

Are viruses living?

No.

Where can viruses reproduce?

Inside living cells

Why are viruses called parasites?

Depend on other organisms to grow and reproduce.

All viruses can be thought of as pathogens. State an example.
