Plants like Elm (Ulmus), Dandelion (Taraxacum) and members of Rose Family vegetatively reproduce by
(1) Rhizome
(2) Sucker
(3) Stolon
(4) Corm
The vegetative propagule of Bryophyllum is:
1. Bulbil
2. Leaf buds
3. Rhizome
4. Offset
Water hyacinth is one of the most invasive weeds primarily because:
1. It gets adapted to any fresh water body easily
2. It produces secondary metabolites against herbivores
3. It can propagate vegetatively at a phenomenal rate
4. It is predated upon by a large number of organisms
Ginger is vegetatively propagated through:
1. Rhizome
2. Bulbil
3. Stolon
4. Offset
Which one of the following statements is not correct?
(1) Offspring produced by the asexual reproduction are called clone
(2) Microscopic, motile asexual reproductive structures are called zoospores
(3) In potato, banana and ginger, the plantlets arise from the internodes present in the modified stem.
(4) Water hyacinth, growing in the standing water, drains oxygen from water that leads to death of fishes.
The 'Eyes' of the potato tuber are
(1) flower buds
(2) shoot buds
(3) axillary buds
(4) root buds
Which form of reproduction is correctly matched?
(1) Euglena → transverse binary fission
(2) Paramecium → longitudinal binary fission
(3) Amoeba → multiple fission
(4) Plasmodium → binary fission
Which one of the following methods is commonly used to maintain the genetic traits of a given plant?
(1) By propagating through seed germination
(2) By propagating through vegetative multiplication
(3) By generating hybrids through intergeneric pollination
(4) By treating the seeds with gamma radiations
No individual is immortal except:
(1) Single celled organisms
(2) Green plants
(3) Sponges
(4) Drones
Individuals of a clone:
