Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Many plants can reproduce asexually. Which of these is an example of asexual reproduction?
A
a potato growing roots
B
night-blooming cactus flowers
C
cross-pollination of a tomato
D
the formation of a pine cone
Explanation: 

Detailed explanation-1: -Potatoes are one example of plants that reproduce through asexual reproduction. Normally plants need two parents. With asexual reproduction, there is only one parent plant. The new plants are clones of the parent plant; they are exactly the same.

Detailed explanation-2: -The potato plant undergoes asexual reproduction via vegetative propagation. Vegetative propagation is the reproduction process in which new plant offspring can be formed from vegetative parts of the plant like root, stem and leaves. Potato contains small eyes/tubers that give rise to leaves in them.

Detailed explanation-3: -Fragmentation is another form of asexual reproduction. It involves new plants growing from small parts of a parent plant that fall to the ground. This is one of the ways that plants like liverworts and mosses reproduce.

Detailed explanation-4: -Potato reproduces asexually by the process called vegetative propagation. Asexual reproduction involves a single parent. The development of new plants from leaves, stem and roots of a plant is called vegetative propagation. Potato grows on underground stems called stolons.

Detailed explanation-5: -Asexual Reproduction Examples Blackworms or mud worms reproduce through fragmentation. Hydras reproduce through budding. Organisms such as copperheads undergo parthenogenesis. Sugarcane can be grown through vegetative propagation.
