Question

Tabulate the process of reproduction into its various types.Give one example of each type.

Answer 1

Hi friend,

Reproduction is a process by which organisms produce new individuals of same species.

Reproduction is of two types-:

•Sexual reproduction- It is a process by which two individuals produce offsprings.Gametes formation takes place.It is a complex process.Variations occurs in it.For example- In humans,cats,dogs.

•Asexual reproduction- It is a process by which one individual produces offsprings.Gametes formation doesn't takes place.Variations doesn't takes place.Its a simple process.

---)Asexual reproduction is of 2 types-

Budding and Binary fission.

Budding takes place in HYDRA,YEAST,ETC.

Binary fission takes place in AMOEBA,ETC.

Hope it helped you..........................

Answer 2

Answer:

The different methods of asexual reproduction are as follows:

(1) Binary fission- The process in which parent cell elongates and gets divided into two identical daughter cells is called binary fission. Each daughter cell grows into an independent adult. It takes place in unicellular organisms.

(2) Endospore Formation- The method in which a spore wall is formed around a bacterial cell to form an endospore is called endospore formation. Under favorable conditions, this endospore germinates to form an active bacteria.

(3) Vegetative propagation- The type of asexual reproduction in which vegetative parts of a plant like stems, leaves, and root, etc. give rise to new ones is called vegetative propagation. Examples: stem cutting in Champa, eye growth in potatoes, bud in case of Myriophyllum.

(4) Budding: It involves the formation of a new organism from a projection called bud. After growing to full size, the budgets detached from a parent and forms a new independent individual. It is commonly observed in yeast.

(5) Spore Formation: In this mode of reproduction, spores germinate and develop into a new individual, under favorable conditions. The spores are tiny spherical unicellular structures protected by a thick wall. It is seen in ferns and moss.

(6) Fragmentation: It is a form of asexual reproduction in which a new organism is formed from the fragments of the parent organism. It is the only mode of asexual reproduction in Spirogyra.
