Cells are of two types:
eukaryotic, which contain a nucleus
, and prokaryotic cells, which do not have a nucleus, but a nucleoid region is still present. Prokaryotes are single-celled organisms, while eukaryotes can be either single-celled or multicellular.

What is cell Class 9?
“A cell is defined as
the smallest, basic unit of life that is responsible for all of life’s processes
.” Cells are the structural, functional, and biological units of all living beings. A cell can replicate itself independently. Hence, they are known as the building blocks of life.
What is inside a cell?
Inside a Cell
A cell consists of
a nucleus and cytoplasm
and is contained within the cell membrane, which regulates what passes in and out. The nucleus contains chromosomes, which are the cell’s genetic material, and a nucleolus, which produces ribosomes. … The endoplasmic reticulum transports materials within the cell.
What are basic cells?
Cells are
the basic building blocks of living things
. The human body is composed of trillions of cells, all with their own specialised function. Cells are the basic structures of all living organisms. … These organelles carry out tasks such as making proteins
?
, processing chemicals and generating energy for the cell.
Which is the largest cell in human body?
The longest cell is the nerve cell. The largest cell in the human body is
female ovum
. Smallest cell in the human body is male gametes, that is, sperm.
How many type of cell do we have?
There are about
200 different types
of cells in the body.
What are the 7 functions of a cell?
The seven processes are
movement, reproduction, response to external stimuli, nutrition, excretion, respiration and growth
.
Which type of cell is more simple?
The primarily single-celled organisms found in the Bacteria and Archaea domains are known as prokaryotes. These organisms are made of
prokaryotic cells
— the smallest, simplest and most ancient cells.
What is the example of cell?
A cell is defined as the smallest unit of an organism with a nucleus. An example of a cell is
a unit in the tissue of an animal muscle
. A small enclosed cavity or space, such as a compartment in a honeycomb or within a plant ovary or an area bordered by veins in an insect’s wing.
What type of cell is Bacteria?
Prokaryotic cells
(i.e., Bacteria and Archaea) are fundamentally different from the eukaryotic cells that constitute other forms of life. Prokaryotic cells are defined by a much simpler design than is found in eukaryotic cells.
