Question

Define, give examples-
- Sexual reproduction
-Asexual reproduction
-Metamorphosis
-Alternation of Generations

Answer 1

Alternation of generations (also known as alternation of phases or metagenesis) is a term primarily used to describe the life cycle of plants (taken here to mean the Archaeplastida). A multicellular sporophyte, which is diploid with 2N paired chromosomes (i.e. N pairs), alternates with a multicellular gametophyte, which is haploid with N unpaired chromosomes.
Sexual reproduction is a method for producing a new individual organism while combining genes from two parents. A single sperm and egg fuse during fertilization , and their genomes combine in the new zygote .
Asexual reproduction is a mode of reproduction by which offspring arise from a single parent, and inherit the genes of that parent only; it is reproduction which does not involve meiosis, ploidy reduction, or fertilization.
Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.
