Question

Ramet is
(a) Clone
(b) Individual of clone
(c) Cell aggregate
(d) Callus

Answer 1

Hint: The offsprings formed by the asexual reproduction or vegetative reproduction have genetic material that is identical to the parent plant and are referred to as clones. They are called ramets when these are found individually in a population.

Complete answer:
Groups of organisms such as plants, fungi, and bacteria that are genetically identical which are obtained from the same ancestors via vegetative reproduction only but not sexual reproduction are called ramets. The genetically identified organisms obtained by vegetative reproduction are called clones. They are genetically similar to the parents. hence ramets are referred to as individuals of clones. In many plant species, colonial colonies are common. The reproduction in most of the plants occurs by the germination of seed i.e, sexual reproduction but some of the plants develop from the vegetative parts like rhizomes, stolons, etc and they form into a colony.

Additional information:
- Woody plants with wide-ranging roots arise into colonial colonies at intervals that send up roots above the ground and grow into new plants and those structures are termed as suckers.
- In plants whose branches help in vegetative propagation by bending down to the ground or developing aerial adventitious roots forms colonies by the process called layering or aerial rooting.
- In some plants like trumpet vine, and ivy, their stem has the ability to develop roots that enter into the ground and forms a new individual.
So, the correct answer is ‘(b) Individual of clone’.

Note:
- All the plants that are formed by asexual reproduction or via vegetative propagation have the same genetic material and are referred to as clones.
- Some of the examples of ramet are Populus tremuloides, myrica pensylvanica, Kerria japonica, etc.
