Question 1

Compare and contrast the structure of bacteria:

Answer 1

[1]
A bacterial cell is simple, small and prokaryotic.

[2]
It has no membrane organelles, but contains a DNA in nucleic region, plasmids and 70s ribosome.

[3]
Its cell wall is made of peptidoglycan.

[4]
A bacteria cell can be in a form of a capsule and flagella may be present.

Question 2

Compare and contrast the structure of plant cells:

Answer 2

[1]
A plant cell is larger and eukaryotic.

[2]
It contains membrane bound organelles that divide labour.

[3]
It contains a cellulose wall

[4]
Vacuole present, but may have lysosomes and 80s ribosomes

[5]
Chloroplast is present in photosynthetic tissues

Question 3

Compare and contrast the structure of fungal cells:

Answer 3

[1]
Fungal cells are eukaryotic and have membrane bound organelles like animal cells, including 80s ribosomes.

[2]
It also have cell wall, but made of chitin.

[3]
It may be multinucleate

[4]
Has a vacuole present

[5]
Its cytoplasm of cells may be connected via septa
