Description
Question 1
Question
The membrane of the vacuole is called the [blank_start]tonoplast[blank_end]. A young plant cell will have many [blank_start]small[blank_end] vacuoles, while a mature plant cell will typically have [blank_start]one[blank_end] big vacuole.
Answer
-
tonoplast
-
small
-
one
Question 2
Question
Choose the correct statements about vacuoles.
Answer
-
They are produced by the Golgi and associated endoplasmic reticulum.
-
They regulate cell turgor.
-
They store ribosomes for protein synthesis.
-
They store primary and secondary metabolites.
-
They contain hydrolytic digestive enzymes.
Question 3
Question
Secondary metabolites are growth associated.
Answer
- True
- False
Question 4
Question
Which of these is not a primary metabolite?
Answer
-
Inorganic ions
-
Organic acids
-
Sugars
-
Lipids
-
Amino acids
-
Proteins
-
All of these are primary metabolites.
Question 5
Question
Choose the incorrect statement about secondary metabolites.
Answer
-
Latex is a secondary metabolite used to deter insects.
-
Secondary metabolites can be for defense or for signalling.
-
Raphides (crystallised calcium oxalate) are a secondary metabolite used to deter larvae.
-
Aloe contains latex in vacuoles.
-
None of these are incorrect.
-
Vincristine and vinblastine are secondary metabolites used to attract pollinators.
-
Anthocyanin is a secondary metabolite which is a pigment.
Question 6
Question
The vacuole can degrade macromolecules and organelles in a process very similar to the lysosomes found in plant cells.
Answer
- True
- False
Question 7
Question
High concentrations of solutes in the vacuole give it a [blank_start]positive[blank_end] osmotic potential. This results in water [blank_start]uptake[blank_end] via osmosis as water moves freely through the tonoplast. The cell wall enables water uptake without [blank_start]bursting[blank_end], creating turgor pressure. [blank_start]Loss[blank_end] of turgor pressure results in wilting but will generally not damage the plant in the long term.
Answer
-
positive
-
negative
-
uptake
-
loss
-
bursting
-
loss of rigidity
-
Loss
-
Gain
Question 8
Question
Chloroplast DNA (ctDNA) is linear.
Answer
- True
- False
Question 9
Question
Match the plastids to their function:
[blank_start]Chloroplasts[blank_end] carry out photosynthesis.
[blank_start]Chromoplasts[blank_end] manufacture and store pigments.
[blank_start]Leucoplasts[blank_end] store starch/assimilates.
[blank_start]Proplastids[blank_end] can differentiate into other plastids.
Answer
-
Chloroplasts
-
Chromoplasts
-
Leucoplasts
-
Proplastids
Question 10
Question
Light reactions take place in the stroma. Dark reactions/the Calvin Cycle take place in the thylakoids/Granum.
Answer
- True
- False
Question 11
Question
The oxygen released from photosynthesis comes from CO2 in the Calvin cycle.
Answer
- True
- False
