There is no nuclear membrane. The cells having nuclear material without nuclear membrane are termed prokaryoticcells. The organisms with these kinds of cells are called prokaryotes (pro : primitive; karyon : nucleus). Examplesare bacteria and blue green algae. The cells, like onion cells and cheek cells having well-organised nucleus witha nuclear membrane are designated as …
The entire content of a living cell is known as protoplasm. It includes the cytoplasm and the nucleus. Protoplasm is called the living substance of the cell.
GeneGene is a unit of inheritance in living organisms. It controls the transfer of a hereditary characteristic from parents to offspring.

Nucleus contains thread-like structures called chromosomes
A smaller spherical body in the nucleus. It is called the nucleolus.
Nucleus is separated from the cytoplasm by a membrane called the nuclear membrane.
Nucleus It is an important component of the living cell. It is generally spherical and located in the centre of the cell. It canbe stained and seen easily with the help of a microscope. Nucleus is separated from the cytoplasm by a membrane called the nuclear membrane. This is also porous and allows the movement …
Cytoplasm is the jelly-like substance present between the cell membrane and the nucleus. Various other components, ororganelles, of cells are present in the cytoplasm. These are mitochondria, golgi bodies, ribosomes, etc
, there is an outer thick layer in cells of plants called cell wall. This additional layer surrounding the cell membrane isrequired by plants for protection. Plant cells need protection against variations in temperature, high wind speed, atmospheric moisture etc.
