What is discovered cell?
The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope.
What is the main function of a cell?
They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves. Cells have many parts, each with a different function.
What are the three basic functions of a cell?
3 Major Functions of a Cell
- Energy Generation. Living cells exist in a perpetually active biological state.
- Molecular Transport. Each cell is surrounded by a membrane that delineates its boundaries and acts as a gatekeeper, controlling the movement of molecules into and out of the cell.
- Reproduction.
What is Cell very short answer?
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 a cell short definition?
A cell is a mass of cytoplasm that is bound externally by a cell membrane. Usually microscopic in size, cells are the smallest structural units of living matter and compose all living things.
What is a cell class 8?
The cell is the basic structural and functional unit of life. All living organisms are made up of cells. Cells make tissues, tissues make organs, organs make organ systems and organ systems make a living organism. Thus, the cell is the building block, or the structural unit of the living body.
Which is the largest cell?

Answer:
- The Cerebellum’s Granule Cell is the smallest cell in the human body that is between 4 micrometers to 4.5 micrometers long.
- The RBC ‘s size also found roughly 5 micrometers.
- Most scientists suggest that sperm is the smallest cell in terms of volume.
What is the function of cell class 8?
The main function of the nerve cell is to transmit messages to the brain from receptor organs and vice versa. It has control over the working of different parts of the body.
What is chloroplast Class 8?
The definition the chloroplast is “containing plastid found within the cells of plants and other photosynthetic eukaryotes.” Chloroplast is a green original only found in plants. They are the food producers of the cell. They are only found in plant cells and some protists. Animal cells do not have chloroplasts.
What are the functions of nucleus class 8?
The nucleus has 2 primary functions:
- It is responsible for storing the cell’s hereditary material or the DNA.
- It is responsible for coordinating many of the important cellular activities such as protein synthesis, cell division, growth and a host of other important functions.
