Which of the following events occurs during sexual reproduction of flowering plants?
(a) Zygote is converted into fruit
(b) Zygote is converted into seed
(c) Unicellular zygote is converted into multicellular embryo
(d) Ovary is converted into embryo
(c) Unicellular zygote is converted into multicellular embryo
Explanation:
During sexual reproduction in flowering plants, fertilization occurs when male and female gametes fuse to form a unicellular zygote. This zygote then undergoes repeated mitotic divisions to develop into a multicellular embryo. Meanwhile, the zygote itself does not directly convert into seed or fruit; rather, the ovule develops into a seed, and the ovary develops into the fruit. Thus, the critical event is the transformation of the unicellular zygote into a multicellular embryo within the seed.

Which of the following statements about self-pollination is correct? Self-pollination occurs within the same flower. New characters do not arise by self-pollination.

As the flowers of pea plant are unisexual, so self-pollination and if needed, cross pollination can be performed.
