Answer: 2: b. fusion of male and female gametes to make a zygote
Explanation: Sexual reproduction can be defined as the mode of reproduction in which the haploid male and female gamete cells fuse to form a diploid zygote cell by the process of fertilization.
Answer 3: c. none of the above
Explanation: The asexual mode of reproduction is used by the simple organisms to produce their offsprings. In this method only a single parent is involved. It does not involve the formation of gametes like in sexual reproduction and no fertilization takes hence, no zygote formation takes place.
Question 1. option c. "production of a gametophyte".
Question 2. option c. "none of the above".
Explanation:
Question 1. Sexual reproduction in plants occurs by the production of a gametophyte. Gametophyte are haploid multicellular organisms that act as sperm and eggs act in humans. Gametophytes are part of the sexual reproduction life cycle of plants, producing a zygote that generates a new plant.
Question 2. Sperm cells, egg cells and zygotes are all part of sexual reproduction. Asexual reproduction involves the production of offspring without the fusion of gametes. Examples of asexual reproduction include: mitosis, binary fission, budding, fragmentation, spore formation and vegetative propagation.
