Q

Why is the Chromosome/DNA different from a plant or animal cell in a bacterial cell?

A

The chromosome/DNA in a bacterial cell is not in the nucleus.

17
Q

What do the Ribosomes do in a bacterial cell?

A

Responsible for protein synthesis.

18
Q

What do the Cell Wall do in a bacterial cell?

A

Important for structure.

19
Q

What does the Flagella do in a bacterial cell?

A

Help the structure to move.

20
Q

What specialises cells?

A

Differentiation.

21
Q

How did microscopes vary over the years?

A

First started off with a basic lens, then moved onto a more complex array of lenses that we now use at school. To the electron microscopes which are massive and controlled by computers.

22
Q

Magnification equation?

A

Magnification = Image height / Object heigh (MIA)

23
Q

What is DNA?

A

DNA is a long strand of deoxyribonucleic acid, made up of lots of letters; A, T, C, G. These twist round to make a double helix. It’s so long it twists round into a chromosome, which is located in the nucleus of the cell.

24
Q

What happens in mitosis?

A

In mitosis we go from one parent cell, to two identical daughter cells.
