Question

define cell and explain it's types​

Answer 1

Answer:

Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed. A single cell is often a complete organism in itself, such as a bacterium or yeast. Other cells acquire specialized functions as they mature

define cell

• in simple words-

A cell is the structural and fundamental unit of life

• This is about cells-.

Cells are the basic, fundamental unit of life.

• You can also say this-

"A cell is defined as the smallest, basic unit of life that is responsible for all of life’s processes.”

Types-

now, it's time about the explaination of its types

There are two types of cells:

• Prokaryotes
• Eukaryotes

Prokaryotic Cells

• Prokaryotic cells have no nucleus. Instead, some prokaryotes such as bacteria have a region within the cell where the genetic material is freely suspended. This region is called the nucleoid.
• They all are single-celled microorganisms. Examples include archaea, bacteria, and cyanobacteria.
• The cell size ranges from 0.1 to 0.5 µm in diameter.
• The hereditary material can either be DNA or RNA.
• Prokaryotes reproduce by binary fission, a form of sexual reproduction.

Eukaryotic Cells

• Eukaryotic cells are characterised by a true nucleus.
• The size of the cells ranges between 10–100 µm in diameter.
• This broad category involves plants, fungi, protozoans, and animals.
• The plasma membrane is responsible for monitoring the transport of nutrients and electrolytes in and out of the cells. It is also responsible for cell to cell communication.
• They reproduce sexually as well as asexually.
• There are some contrasting features between plant and animal cells. For eg., the plant cell contains chloroplast, central vacuoles, and other plastids, whereas the animal cells do not

• Who discovered cells?

Robert Hooke discovered the cell in 1665.

Characteristics of Cells

Following are the various essential characteristics of cells:

• Cells provide structure and support to the body of an organism.
• The cell interior is organised into different individual organelles surrounded by a separate membrane.
• The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth.
• Every cell has one nucleus and membrane-bound organelles in the cytoplasm.
• Mitochondria, a double membrane-bound organelle is mainly responsible for the energy transactions vital for the survival of the cell.
• Lysosomes digest unwanted materials in the cell.
• Endoplasmic reticulum plays a significant role in the internal organisation of the cell by synthesising selective molecules and processing, directing and sorting them to their appropriate locations.

Cell Structure

• The cell structure comprises individual components with specific functions essential to carry out life’s processes. These components include- cell wall, cell membrane, cytoplasm, nucleus, and cell organelles
