Flashcards in Cell Biology Deck (15):
1

What are eukaryotic cells?

Animal and plant cells

2

What are prokaryotic cells?

Bacteria cells- they are much smaller and simpler

3

What is a nucleus?

Contains genetic material that controls the activities of the cell

4

What is a mitochondria?

These are where most of the reactions for aerobic respiration takes place. Respiration transfers energy that the cell needs to work

5

What is cytoplasm?

Gel-like substance where most of the chemical reactions happen. It contains enzymes that control these chemical reactions

6

What is a cell membrane?

It holds the cells together and controls what goes in and out of the cell

7

What are ribosomes?

Where proteins are made in the cell

8

What are cell walls?

Made of cellulose. It supports the cell and strengthens it

9

What are chloroplasts?

Where photosynthesis occurs, which makes food for the plant. They contain chlorophyll, which absorbs the light needed for photosynthesis

10

What is a vacuole?

Contains cell sap, a weak solution of sugar and salts

11

What are plasmids?

One of more small rings of DNA

12

What do bacteria cells have instead of a ‘true’ nucleus

They have a singular circular strand of DNA that floats freely in the cytoplasm

13

What are the differences between an electron microscope and light microscope?

Higher magnification
Higher resolution
More expensive
Vacuum

14

What is differentiation?

The process by which a cell changes to become specialised for its job

15

How are sperm cells specialised?

Long tail
Streamlined head
Lots of mitochondria
Carries enzymes
