prokaryotic and eukaryotic

. Prokaryotic cells lack a nucleus and other membrane-bound organelles. Eukaryotic cells have a nucleus and other membrane-bound organelles.

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.

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.

What is the main function of cell?

Cells provide six main functions. They

provide structure and support

, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction.

What is 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.

Where do cells come from?

All cells come

from pre-existing cells by cell division

. Schwann also proposed “Free Cell Formation” or spontaneous generation of cells — this was before Pasteur’s definitive experiments. Modern Cell Theory Also States: Life’s chemical processes, such as metabolism, occur inside of cells.
