About the Well Labelled Diagram of Animal Cell;
The well labelled diagram of an animal cell depicts the various organelles that are found in a typical animal cell. Some of the organelles shown include the nucleus, the mitochondria, the endoplasmic reticulum, the Golgi apparatus, the lysosomes and the plasma membrane. The diagram also shows the cytoplasm and the cell membrane.
A Well Labelled Diagram of Animal Cell
A well labelled diagram of an animal cell shows the major organelles and their functions. The cell membrane is the outermost layer of the cell and it surrounds the cell cytoplasm. The cytoplasm is the internal organelle and it contains the cell nucleus and other organelles. The cell nucleus is the largest organelle and it contains the cell’s genetic material. The mitochondria are the organelles that produce energy for the cell and the endoplasmic reticulum is the organelle that manufactures proteins. The Golgi apparatus packages proteins for transport within the cell and the lysosomes are the organelles that break down cellular waste products. The cell membrane is selectively permeable and it allows some substances to enter and exit the cell while preventing other substances from entering or exiting.
Cell Membrane/Plasma Membrane
The cell membrane is a lipid bilayer that surrounds the cells of all living organisms. It is composed of two layers of phospholipids, which are arranged so that the hydrophobic (water-hating) tails of the phospholipids are pointing inward and the hydrophilic (water-loving) heads are facing out. This creates a barrier that prevents water-soluble molecules from entering or leaving the cell. The plasma membrane is the cell membrane of a eukaryotic cell.
Cytoplasm/Cytosol
Cytoplasm is the semifluid substance that occupies the cells of living organisms. It is composed of water, proteins, lipids, and other organic and inorganic molecules. The cytosol is the portion of the cytoplasm that is not occupied by organelles.
The Nucleus
The nucleus is a small, dense region of an atom that contains the atom’s genetic material. The nucleus is surrounded by a protective layer of electrons. The nucleus contains the protons and neutrons of the atom.
Ribosomes
are organelles in the cell that are responsible for protein synthesis. They are small, round, and made up of proteins and RNA. Ribosomes attach to the end of the mRNA molecule and use the sequence of codons to create a protein.
The Endoplasmic Reticulum
The endoplasmic reticulum is a membranous network of tubes and sacs that extends throughout the cytoplasm of a eukaryotic cell. It is involved in the processing of proteins and lipids. The endoplasmic reticulum consists of two main types of compartments: the rough endoplasmic reticulum and the smooth endoplasmic reticulum.
The rough endoplasmic reticulum is studded with ribosomes, which are the sites of protein synthesis. The proteins that are synthesized on the ribosomes are transported to the smooth endoplasmic reticulum, where they are processed and folded into their correct shapes. The smooth endoplasmic reticulum is responsible for the secretion of proteins and lipids from the cell.
Golgi Apparatus
The Golgi apparatus is a cellular organelle that is found in the cytoplasm of eukaryotic cells. It is a membranous sac that is about 1-2 micrometers in diameter and is about 5 micrometers long. The Golgi apparatus is responsible for the processing and transport of proteins and lipids that are synthesized in the endoplasmic reticulum.
The Golgi apparatus has a number of important functions, including the:
– Processing of proteins and lipids that are synthesized in the endoplasmic reticulum
– Transport of proteins and lipids to other cellular organelles
– Secretion of proteins and lipids to the outside of the cell
– Assembly of complex proteins
The Mitochondria
The mitochondria are organelles in the cytoplasm of the cell. They are unique in that they have their own DNA, which is separate from the DNA in the nucleus. The mitochondria are responsible for producing energy for the cell.
FAQs
Q1. What is an animal cell?
A1. An animal cell is a type of eukaryotic cell, which is a cell that contains a membrane-bound nucleus. Animal cells also have other organelles such as mitochondria, lysosomes, and endoplasmic reticulum. These organelles help the cell to perform its various functions.
Q2. What is the difference between animal cells and plant cells?
A2. The major difference between animal cells and plant cells is that plant cells have a cell wall, while animal cells do not. Plant cells also have chloroplasts, which are not found in animal cells. Additionally, plant cells contain plastids, which are organelles that store pigments or starch, while animal cells do not.
Q3. How big is an animal cell?
A3. The size of an animal cell can vary depending on the type of cell. Generally, animal cells range in size from 10-30 micrometers in diameter.
Q4. What are the components of an animal cell?
A4. The components of an animal cell are the nucleus, cytoplasm, endoplasmic reticulum, Golgi apparatus, mitochondria, lysosomes, and vacuoles. The nucleus is the center of the cell and houses the genetic material. The cytoplasm is the jelly-like substance that houses the other organelles. The endoplasmic reticulum is responsible for protein synthesis and the Golgi apparatus is responsible for packaging and transporting proteins and other molecules. Mitochondria are responsible for producing energy for the cell and lysosomes are responsible for breaking down proteins and other molecules. Vacuoles are fluid-filled structures that are responsible for storing water, salts, and other molecules.
Q5. What is the function of an animal cell?
A5. The main function of an animal cell is to provide a structure for the cell and to allow the cell to perform its various activities. Animal cells are responsible for growth, reproduction, metabolism, and response to stimuli.
