Prokaryotic Cells: These are the cells that do not have the exact nucleus. All the single-celled or unicellular organisms comprising amoeba, bacteria, and paramecium are gathered into prokaryotes.

Eukaryotic Cells: These are the cells with the exact nucleus and other particular organelles. All the multicellular organisms comprising plants, animals, algae, birds, reptiles are grouped into eukaryotes and are collected from many cells.

Plant Cell

Plant cells are eukaryotic cells with an exact nucleus along with particular structures known as organelles that carry out definite functions.

Animal Cell

An animal cell is a type of eukaryotic cell that has an absence of a cell wall and has an exact, membrane-bound nucleus along with other cellular organelles.

Cell Organelles

The cellular constituents are known as cell organelles. These are membrane-bound, present within the cells, and are different in their structures and functions. They manage with their functions professionally for the usual functioning of the cell. Few of them functions offering shape and support, whereas some are included in the locomotion and reproduction of a cell. There are different organelles present within the cell and are categorized into three groups based on the presence or absence of membrane.

Cytoplasm

The cytoplasm is available both in plant and animal cells. They are jelly-like material, found between the cell membrane and nucleus. The cytoplasm is one of the vital constituents of the cell, where all the cell organelles are surrounded.
