While playing near a sugarcane field, Mohan noticed that the plants are almost similar to one another. At the same time, he noticed the mango trees in the next plot of land which are not similar to one another. Mohan’s brother told Mohan that sugarcane reproduces asexually, hence there is little variation, Mango reproduces sexually, and hence there is larger variation.
(a) Why sugarcane cannot reproduce sexually?
(b) Can mango reproduce asexually?
(c)If a person wants to have a flower garden, what type of plants should he grow?
Answers
Answer:
a) because it has no flower to produce gametes
b) no
c) he should grow rose and marigold
a) No sexual reproduction in sugarcane.
b) Mango - both sexual and asexual reproduction.
c) vegetative propagation.
Explanation:
a) In fact sugarcane reproduces asexually by the use of pieces of the stem called setts or cuttings of the plant that contain at least one node. No sexual reproduction.
b) The two basic propagation options for mangoes are by seed or grafting. Mango seeds are either mono-embryonic or poly-embryonic depending on the variety. Only poly-embryonic seeds produce true-to-type (clones) of the parent. Most cultivars of mango do not produce seedlings true-to-type. Therefore, grafting is often necessary to overcome this problem. Grafting also means that trees produce uniform yield, fruit size and quality. Yes, both sexual and asexual reproduction is possible.
c) If a person wants to have a flower garden then he should grow flowering plants like chrysanthemum, rose, etc., obtained from vegetative propagation.
