$\bold{→What \: is \: a \: cell?} \\ \bold{What \: is \: cell \: known \: as? \: Explain?}$

$\huge\mathbf\red {\underline{\underline{Answer:}}}$

• $\bold{Cells \: are \: the \: basic \: building \: blocks \: of \: all \: living things.} \\ \bold{ ... Cells \: also \: contain} \bold{ the \: body's \: hereditary} \\ \bold {material \: and \: can \: make \: copies \: of \: themselves.}$

$\huge\mathbf{\underline{\underline{Explanation:}}}$

$→$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

$\huge\bold{Question:-}$

What is Cell?

$\huge\bold{Answer:-}$

• A cell is defined as the smallest , basic unit of life that is responsible for all of life processes
• So, It is also known as Building Block of Life
• Cell is first discovered by Robert Hooke in the year 1665
• Robert Hooke observed a piece of bottle cork under a compound microscope and noticed minuscule structures that reminded him of small rooms.

Characteristics of Cell:-

• 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.

Types of Cells:-

Cells are similar to factories with different labourers and departments that work towards a common objective. Various types of cells perform different functions. Based on cellular structure, there are two types of cells:

1. Prokaryotes
2. Eukaryotes

--------> 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.

Eg:- archaea, bacteria, and cyanobacteria.

----------> Eukaryotic cells are characterised by a true nucleus.

The size of the cells ranges between 10–100 µm in diameter.

Eg:- plants, fungi, protozoans, and animals.
