What sub-cellular structures do animal cells have in them?
a nucleus, cytoplasm, a cell membrane, mitochondria and ribosomes.
2 of 30
What does the nucleus do in animal cells?
controls the activities of the cell and contains the genetic material.
3 of 30
What happens in the cytoplasm?
most of the chemical reactions take place here.
4 of 30
What does the cell membrane do?
controls the passage of substances into and out of the cell.
5 of 30
what does the mitochondria do?
where the aerobic respiration takes place.
6 of 30
what happens in the ribosomes?
where proteins are synthesised.

what do plant cells contain that all other cells contain?
sub-cellular structures.
8 of 30
what do plant cells have in them?
a cell wall, permanent vacuole.
9 of 30
what is the cell wall made of?
cellulose, which strengthens the cell.
10 of 30
what is the permanent vacuole made of?
filled with cell sap, which supports the .
11 of 30
what do plants need to make their own food?
chloroplasts.
12 of 30
where can these cholroplasts be found?
in some of their cells.
13 of 30
what do chloroplasts do to make food?
absorb light to make food (glucose) by photosynthesis.
14 of 30
true or false: 'not all plant cells have chloroplasts'
true because for example they are not present in root cells because these cells do not recieve any light.
15 of 30
what are the two main types of cell?
prokaryotic and eukaryotic
16 of 30
what type of cell are plant, animal and fungal?
eukaryotic
17 of 30
what type of cells are bacterial cells?
prokaryotic
18 of 30
what is a prokaryotic cell like?
generally smaller in size and, the genetic material is not enclosed in a nucleus, the genetic material is a single DNA loop and there may be one ore more small rings of DNA called plasmids and they do not contain mitochondria or chloroplasts.
19 of 30
what does a typical bacterial cell look like?
Bacterial cells have many different shapes, some are round, some rod-shaped, and some spiral but they are all prokaryotic cells.
20 of 30
what is the round bacterial cell called?
spherical
21 of 30
what is the tablet shaped cell called?
rod
22 of 30
what is the spiral shaped cell called?
spiral
23 of 30
what is the curved cell called?
curved rod
24 of 30
what roles does the cytoplasm take over in bacterial cells?
mitochondria and chloroplasts
25 of 30
what are flagella?
tail like structures, that move the bacterium
26 of 30
what are plasmids?
loops of DNA that can be transferred from one cell to another
27 of 30
what do plasmids allow bacterial cells to do?
move genes from one cell to another
28 of 30
which cell do scientists think were discovered first?
prokaryotic
29 of 30
what do plasmids allow scientists to do?
allow genes to be inserted into bacteria for genetic engineering.
