1
Q
cell wall
A
- protects living contents inside PLANT cell
- gives rigidity to PLANT cell
2
Q
cytoplasm
A
- site of all metabolic processes
- cyclosis (substances circulate)
- stores substances
- helps maintain shape of cell
3
Q
cell membrane
A
- selectively permeable and controls movements of substances in and out of the cell
4
Q
nucleus
A
- control centre
- chromosomes carry hereditary characteristics
5
Q
mitochondria
A
- cellular respiration
6
Q
ribosomes
A
- site of protein synthesis (process where 51 (or more) amino acids join to form a protein)
7
Q
endoplasmic reticulum (ER)
A
- transports substancces from one part of the cytoplasm to another
- increases internal surface area of cell
8
Q
golgi body
A
- producing and processing secretions
- prepares proteins for transport to other parts of cell
9
Q
plastids- chloroplasts
A
- photosynthesis
10
Q
plastids- chromoplasts
A
- gives fruits and flowers red, orange and yellow colour
11
Q
plastids- leucoplasts
A
- become specialised to store food in form of starch, lipids or proteins
12
Q
vacuoles
A
- cell sap causes turgor pressure, giving plant rigidity
- cell sap contains anthocyanins- give flowers and fruit blue and purple colour
13
Q
vacuoles- contractile vacuoles
A
- osmoregulation (controls cell’s water balance)
14
Q
vacuoles- food vaccuoles
A
- play role in digestion and storage of food
15
Q
vacuoles- vesicles
A
- transport substances from golgi body to other parts inside and outside cell
16
Q
vacuoles- lysosomes
A
- play role in food disgestion in unicellular animals
17
Q
centrosomes
A
- play role in formation of spindle during mitosis
