Lesson 6 - Eukaryotic cells 4

Question 1

meaning tonoplast

Answer 1

the specialised membrane that surrounds the permanent vacuole in plant cells and controls movements of substances into and out of the cell sap

Question 2

meaning cell sap

Answer 2

the aqueous solution that fills the permanent vacuole

Question 3

meaning chloroplast

Answer 3

an organelle adapted to carry out photosynthesis containing the green pigment chlorophyll

Question 4

meaning chlorophyll

Answer 4

a green pigment that is responsible for trapping the energy from light, making it available for the plant to use in photosynthsis

Question 5

meaning amyloplast

Answer 5

plant organelles that store starch

Question 6

what does the permanent vacuole store

Answer 6

pigments, proteins, lytic enzymes and waste products

Question 7

function of cell sap

Answer 7

causes water to move into the cell by osmosis

Question 8

which plant cells do not contain chloroplast

Answer 8

parasitic plants, flowers, seeds, internal cells of stems and transport tissues

Question 9

state 4 similarities between chloroplast and mitochondria

Answer 9

• large organelles with a biconvex shape
• contain their own DNA
• double membrane-bound
• have a folded inner membrane

Question 10

state 3 differences between chloroplast and mitochondria

Answer 10

• chloroplast is the site of photosynthesis, whilst mitochondria is the site of aerobic respiration
• chloroplast contains chlorophyll, whilst mitochondria doesn’t
• chloroplast is formed from leucoplast, whilst mitochondria isn’t

Question 11

what is amyloplast formed from

Answer 11

leucoplast
