REPRODUCTION IN PLANTS AND ANIMALS

Ø Reproduction is the biological process by which organisms give birth or give rise to a new organism.

Ø This process is seen in all living organisms- both plants and animals.

Asexual Reproduction:

Ø Production of an offspring by a single parent without the formation and fusion of gametes is called asexual reproduction.

Ø Asexual reproduction occurs by spore formation.

Ø This is the most common method of asexual reproduction in fungi and bacteria.

Sexual Reproduction in Plants:

Ø Sexual reproduction is the process in which two gametes (male and female) are fused to produce offspring of their own kind.

Ø In such cases both sexes, male and female sex organs are needed to produce gametes.

Structure of the Ovule:

Ø The main part of the ovule is the nucellus which is enclosed by two integuments leaving an opening called as micropyle.

Ø The ovule is attached to the ovary wall by a stalk known as funiculus.

Ø Chalaza is the basal part.
