Bryophyllum propagates through spore formation.

  1. False

  2. True

  3. Ambiguous

  4. Data insufficient


Correct Option: A
Explanation:

Bryophyllum produces plantlets along the margins of its leaves. When they mature, they drop off and root in any suitable soil beneath thereby performing the function of vegetative propagation.
Thus, the correct answer is option (A), '
False'.

Vegetative propagation refers to formation of new plants from

  1. Stem, roots and flowers

  2. Stem, roots and leaves

  3. Stem, flowers and fruits

  4. Stem, leaves and flowers


Correct Option: B
Explanation:

Vegetative propagation is type of asexual reproduction in which new plant is produced from root, stem, leaves and bud. New plant is produced from vegetative part so it is called as vegetative propagation.

The vegetative reproduction in sweet potato is done by

  1. Stem

  2. Leaf

  3. Root

The vegetative propagation of sweet potato can be done by roots. Sweet potato is a modification of adventitious roots, which grow from the nodes of a running stem and they are irregularly swollen due to storage of food. They can give rise to adventitious buds, which when detached can give rise to new plants thus performing the function of vegetative propagation.
Thus, the correct answer is option (C), 'Roots'.
