Chapter 25, Problem 1STP

Summary Introduction

Introduction :

The plants are the photosynthetic eukaryotes. They show sexual and asexual mode of reproduction. In the sexual mode of reproduction, fusion of the male and the female gametes takes place and in the case of asexual reproduction, the plant is produced by any part of the plant, such as roots, stems, leaf node, etc.

Answer to Problem 1STP

Correct answer :

Option (D).

Explanation of Solution

Explanation/justification for the correct answer :

Option (D) vegetative. In case of plants, asexual reproduction is also called vegetative reproduction. The vegetative production takes place when any part of plant other than fertilized embryo, give rise to complete plant. In this case a part of mass give rise to a new plant so, it is a vegetative reproduction. Hence, the correct answer is option (D).

Explanation for incorrect answer :

Option (A)Alternation of generations. It is referred to a phenomenon, which occurs in many organisms, mostlyin plants, in which they have two different life forms in a single life cycle. Plant showingalternation of generations can exist in two phases gametophyte and the sporophyte.Hence, it is an incorrect answer. Option (B) gametophyte reproduction. The gametophyte reproduction involves fusion of gametes.In this case there are no gametes involved. Hence, it is an incorrect answer.

Option (C) Sporophyte generation. The sporophyte generation involves formation of plant from spores. Hence, it is an incorrect answer.
