Asexual Reproduction

During fertilisation in plants the male and female gametes unite, triggering the process of cell division followed by seed formation. A gene $\mathrm{BBM}1$, expressed only in the male gamete, is responsible for eliciting rapid cell division. A researcher overexpressed the $\mathrm{BBM}1$ gene in the female gamete that resulted in the multiplication of the female gamete into an embryo and then the seed. The plants obtained from these seeds were genetically identical to the parent. This phenomenon is commonly seen in a few select plants naturally, and is known as

Define plasmotomy.

Oblique Binary fission is a kind of asexual reproduction in which plane is divided obliquely resulting in the formation of two unequal daughter cells.

Draw the diagram of oblique binary fission process.

Cell division itself is a mode of reproduction in

During unfavourable conditions, Amoeba reproduces by:

Hydra reproduces by internal budding.

Differentiate between the internal and external budding.

The process in which the offspring formed by internal budding eats their own mother is called_____.

What do you understand by endodyogeny?

In lower marine, diploblastic organisms, the internal budding results in the formation of gemmules.

Assertion $\left(\mathrm{A}\right)$: Symmetrogenic binary fission takes place in Paramoecium

Reason $\left(\mathrm{R}\right)$: The cytopharynx of the parent is retained by the proter.
