Natural Vegetative Propagation
1 / 15
Vegetative propagation is a type of reproduction in which new plants arise from:
Reasoning: Vegetative propagation uses stems, roots, or leaves instead of seeds.
2 / 15
Which of the following is an example of stem-based vegetative propagation?
Reasoning: Potato tuber is a modified stem used for reproduction.
3 / 15
The “eyes” of a potato are actually:
Reasoning: Eyes are buds that grow into new shoots.
4 / 15
Suckers are best described as:
Reasoning: Suckers grow from the base and form new plants.
5 / 15
Which plant commonly reproduces by suckers?
Reasoning: Mint produces suckers that grow into new plants.
6 / 15
Leaf-based vegetative propagation is commonly seen in:
Reasoning: Bryophyllum produces plantlets on leaf margins.
7 / 15
In Bryophyllum, new plants develop from:
Reasoning: Adventitious buds form on leaf edges.
8 / 15
Which part of ginger is used in vegetative propagation?
Reasoning: Ginger reproduces through underground stem (rhizome).
9 / 15
A key feature of vegetative propagation is that offspring are:
Reasoning: It produces clones of the parent plant.
10 / 15
Which of the following is NOT a stem modification used in vegetative propagation?
Reasoning: Stigma is a part of the flower, not stem.
11 / 15
A potato plant produces new plants because it contains:
Reasoning: Buds in tubers develop into shoots.
12 / 15
Suckers help plants to:
Reasoning: Suckers allow rapid vegetative spread.
13 / 15

Reasoning: Bryophyllum forms plantlets on leaves.
14 / 15
Vegetative propagation through stem includes:
Reasoning: These are stem modifications used in reproduction.
15 / 15
The main advantage of vegetative propagation is:
Reasoning: It quickly produces clones with desired traits.
