Animal Cell 

Animal cell is a type of Eukaryotic cell i.e. they have a defined nucleus and membrane-bound organelles.Animal cell is the basic unit of  the tissues and organs of animals. 

Animal cells have a cell membrane, a Cytoskeleton, and a nucleus that contains genetic material. They also contain many organelles such as mitochondria which generates energy for the cell, Endoplasmic Reticulum and Golgi apparatus, which plays an important role in  protein synthesis and transport. 

Animal cells do not have a cell wall,  irregular and smaller size unlike Plant Cells. They also have centrioles which play an important role in cell division. Some animal cells also have cilia and flagella which helps in cell movement. Some animal cells also have a cytoskeleton, which provides structural support and helps in cell movement.

Description of Animal Cell Diagram labels is as follows

Cell Membrane 

Cell membrane is a thin, flexible barrier that surrounds the Animal cell . It is called a selectively permeable Membrane as it controls the movement of materials in and out of the cell.

Nucleus 

Nucleus is the  organelle of the  animal cell which is in the center.It contains  genetic material (DNA) and also  controls the cell’s activities.

Nuclear Envelope 

Nuclear envelope is the double-membrane structure that covers  the nucleus .It acts as a barrier to protect the genetic material.

Nuclear Pore 

Nuclear pores are openings on the nuclear envelope that allows the exchange of materials between the nucleus and the cytoplasm.

Cytoskeleton 

Cytoskeleton is the network of protein fibers. It provides structure and support to the cell. It also  helps to maintain cell shape and movement.

Endoplasmic Reticulum (ER) 

The Endoplasmic Reticulum is the network of flattened sacs and tubules which plays an important role in protein synthesis and transport.There are two types of Endoplasmic Reticulum– ROugh Endoplasmic Reticulum and Smooth Endoplasmic Reticulum.

Ribosomes

Ribosomes are small organelles which are responsible for protein synthesis.

Golgi Apparatus 

Golgi apparatus is a stack of flattened sacs which plays an important role in  modifying, sorting  and transporting proteins and lipids.

Mitochondria 

Mitochondria are the organelles that generate energy for the cell through cellular respiration. They are also called the powerhouse of the cell.

Lysosomes

Lysosomes are the small organelles that contain enzymes . It plays an important role in breakdown and recycling cellular waste.

Centrioles

Centrioles are the cylindrical small structures that are found in pairs in animal cells. Centrioles play an  important role in cell division by separating the chromosomes during cell division.

Microvilli 

Microvilli are small, finger-like projections on the cell membrane. It increases the surface area of the cell .They play an important role in absorption and sensing of the cell.

Cilia

Cilia are small, hair-like structures which protrude from the surface of some cells. They play an important role in  movement. Example – The movement of mucus in the respiratory tract. 

Flagella

Flagella are similar to cilia. but they are longer and thicker as compared to cilia . Flagella are used for movement. For example  the movement of sperm cells.

Peroxisomes

Peroxisomes are small, round cell  organelles which contain enzymes that break down certain molecules like  fatty acids and amino acids. They play an important role in detoxifying harmful substances in the cell.

Microfilaments

Microfilaments are thin, rod-like structures which make the cytoskeleton of the animal  cell. They provide structural support and help to maintain the shape of the animal cell.

Intermediate filaments

Intermediate filaments are thicker and stronger than microfilaments.it also makes up the cytoskeleton. They also provide structural support to the cell and help to resist mechanical stress.
