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. ... Hence, they are known as the building blocks of life.
What is a cell answer in one word?
Cell is the structural and functional unit of an living organism. In other words, (only for better understanding) Cell is the building blocks of an living organism .

Trees in a forest, fish in a river, horseflies on a farm , lemurs in the jungle, reeds in a pond, worms in the soil — all these plants and animals are made of the building blocks we call cells. Like these examples, many living things consist of vast numbers of cells working in concert with one another.
What are the two cell types?
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 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.
