Question

WHAT IS A CELL? WHAT ARE THE FUNCTIONS OF CELL?

Answer 1

$\bigstar$ Cells :

All living organisms are made of cells. A cell is the basic unit of structure of all living organisms. Plants and cells are made of trillions of cells. Some living organisms consist of only one cell, e.g bacteria. Cells are different in sizes, shapes, and functions.

Types of Cells :

• Skin cells.
• Bone cells.
• Nerve cells.
• White blood cells (WBC)
• Red blood cells. (RBC)
• Muscle cells.

Skin cells :

Skin cells cover boy and protect inner layers.

Bone cells :

Bone cells produce bones in shape and support bones.

Nerve cells :

Nerve cells conduct messages to brain.

White blood cells (WBC) :

White blood cells fight against germs cause diseases.

Red blood cells (RBC)  :

Red blood cells transport oxygen around the body.

Muscle cells :

Muscle cells contract and bring about movement.

Answer 2

What is a cell?

Cells are the fundamental structure squares of every single living thing. The human body is made out of trillions of cells. They give structure to the body, take in supplements from nourishment, convert those supplements into vitality, and complete particular capacities. Cells additionally contain the body's genetic material and can make duplicates of themselves.  

Cells have numerous parts, each with an alternate capacity. A portion of these parts, called organelles, are specific structures that play out specific undertakings inside the cell. Human cells contain the accompanying significant parts, recorded in order request:

Cytoplasm

Inside cells, the cytoplasm is comprised of a jelly-like liquid (called the cytosol) and different structures that encompass the nucleus.

Cytoskeleton  

The cytoskeleton is a system of long filaments that make up the cell's basic structure. The cytoskeleton has a few basic functions, including deciding cell shape, taking an interest in cell division, and enabling cells to move. It likewise gives a track-like framework that coordinates the development of organelles and different substances inside cells.  

Endoplasmic reticulum (ER)  

This organelle helps process atoms made by the cell. The endoplasmic reticulum additionally move these particles to their particular goals either inside or outside the cell.  

Golgi apparatus

The Golgi apparatus bundles particles handled by the endoplasmic reticulum to be moved out of the cell.  

Lysosomes and peroxisomes

These organelles are the reusing focal point of the cell. They digest outside microscopic organisms that attack the cell, free the cell of harmful substances, and reuse destroyed cell segments.  

Mitochondria  

Mitochondria are unpredictable organelles that convert vitality from sustenance into a structure that the cell can utilize. They have their own hereditary material, separate from the DNA in the nucleus, and can make duplicates of themselves.  

Nucleus  

The nucleus fills in as the cell's command center, sending headings to the cell to develop, develop, separation, or pass on. It likewise houses DNA (Deoxyribonucleic Acid), the cell's genetic material. The nucleus is encompassed by a membrane called the nuclear envelope, which secures the DNA and isolates the nucleus from the remainder of the cell.  

Plasma membrane

The plasma membrane is the external covering of the cell. It isolates the cell from its condition and enables materials to enter and leave the cell.  

Ribosomes  

Ribosomes are organelles that procedure the cell's hereditary directions to make proteins. These organelles can glide unreservedly in the cytoplasm or be associated with the endoplasmic reticulum.
