Homework Answers
There are two modes by which animals reproduce. These are:
(i) Sexual reproduction, and
(ii) Asexual reproduction.
There are many organisms which do not reproduce (mules, sterile worker bees, infertile
human couples, etc.).
Sexual Reproduction
The reproductive parts in animals produce gametes that fuse to form a zygote. It is the
zygote which develops into a new individual. This type of reproduction beginning from
the fusion of male and female gametes is called sexual reproduction.
The male reproductive organs include a pair of testes (singular, testis), two sperm
ducts and a penis. The testes produce the male gametes called sperms.
The female reproductive organs are a pair of ovaries, oviducts (fallopian tubes) and
the uterus. Ovary produces female gametes called ova (eggs).
In human beings, a single matured egg is released into the oviduct by one of the ovaries
every month. Uterus is the part where development of the baby takes place. Like the
sperm, an egg is also a single cell.
The first step in the process of reproduction is the fusion of a sperm and an ovum. When
sperms come in contact with an egg, one of the sperms may fuse with the egg. Such
fusion of the egg and the sperm is called fertilization.

Phylum Hepatophyta:
Liverworts
Like the moss, liverworts begin as a haploid spore. As a
liverwort spore germinates, it develops into a flat, lobed,
leaf-like structure called a thallus. The thallus
grows prostrate with the ground’s surface, forming
rhizoids that anchor it in place.
Liverworts reproduce asexually primarily by
fragmentation; however, some liverworts may also
reproduce asexually by bundles of tissue called
gemmae. In many liverworts, gemmae develop in
small cup-like structures called gemmae cups.
Splashed from the cups by rain,...
