These are the monerans which are without cell wall and are the smallest cellular entities.

Like animals they have glycogen as their main reserve food material.

These are the enucleated protoplasts whose activities are controlled by companion cells.

Photosynthetic bacteria uses sunlight and chemosynthetic organisms use the chemical energy.

Hair are present in this zone to increase the surface area and thus, absorbs more water.

It is the nucleoid which is a circular DNA of prokaryotes.

This is the study of pathogen in relation to host and the causes of disease.

Lysosomes have the digestive enzymes for the breakdown of bonds.

They are very active cells and require more energy.

The regions of DNA packed in facultative heterochromatin will not be consistent between the cell types within a species, and thus is a sequence in one cell that is packed in facultative heterochromatin.

Glycogen is the reserve food in animals and starch is the reserve food in plants.

Alleles are always present on the same locus of homologous chromosomes for crossing over.

It is the sexual reproduction in which a bud arises from the main cell of body.

It is the basal cell of the filament which helps in its attachment to the substrate.

In this condition, flagella is present on one end of the cell in a tuft.

It is the condition in which the mega and microspores are distinguishable from each other.

This division involves recombination due to which this step is unique to meiosis.

It occurs due to change in the allosteric site.

This is the kingdom of the photosynthetic organisms.

The lamina is silicate type due to the presence of silica grains.
