Asexual reproduction is carried out by:

The number of taxa exhibiting asexual reproduction is drastically reduced in higher plants (angiosperms) and higher animals (vertebrates) as compared with lower groups of plants and animals. Analyse the possible reasons for this situation.

$A$ bacterium divides every $35$ minutes. If a culture containing $10^5$ cells/ml is grown for $175$ minutes,what will be the cell concentration/ml after $175$ minutes?

In $Ophioglossum$ (a fern),the chromosome number in a gamete is ..... and in potato,the chromosome number in a gamete is ....

$Statement\; 1$: $A$ plant can be retained and multiplied indefinitely without any change or variation through asexual reproduction.
$Statement\; 2$: Asexual reproduction does not involve meiosis and syngamy.

Organisms showing internal fertilisation show a reduction in the number of . . . . . . gametes and an increase in the number of . . . . . . gametes.
