Question

what is a cell? how it works​

Answer 1

$\huge\fbox\red{Answer}$

Cell

Cell is the smallest structural and functional unit of an organism. It is the building block of a living organism. It is membrane-bound and is made up of cytoplasm, genetic material and other cell organelles or components.

How does it works ?

Cells get raw materials — including water, oxygen, minerals and other nutrients — from the foods you eat. They let in raw materials through the cell membrane: the thin, elastic structure that forms the border of each cell. Cells have internal structures called organelles. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.

Answer 2

• The simplest structural and functional unit in life is the cell.
• The cytoplasm of every cell is surrounded in a membrane and includes various substances such as proteins and nucleic acids.
• A light microscope is the sole way to observe most plant and animal cells, which range in size from 1 to 100 micrometers.
• Electron microscopy offers a much higher resolution than conventional microscopy and may disclose a lot more information about the cell structure.
• Unicellular organisms (such as bacteria) and multicellular organisms (comprising numerous cells) are the two types of organisms (including plants and animals).
• The bulk of single-celled creatures are microorganisms.
• Plants and animals have different cell counts depending on the species.
• There are 40 trillion (41013) cells in the human body, according to estimates.
• The brain has around 80 billion of these cells.
