Animal Cell Structure

All mammalian cells are eukaryotic, and whilst the eukaryotic type of cell is not exclusive to mammals, mammalian cells differ from other eukaryotic cells because of the organelles that are or are not present. For instance some plant cells have chloroplasts which are not present in mammalian cells, but both plant cells and mammalian cells are eukaryotic in nature. The term eukaryotic refers to the cell having specific membrane bound organelles, which are not present in prokaryotic cells. The defining feature of a eukaryotic cell is usually its membrane bound nucleus (the exception being the red blood cell) [1].

For a plant cell, the nucleus, without a doubt, is the most important organelle; but in the animal cell, the most vital structure is the mitochondria.

Eukaryotes include all living animal organisms other than the eubacteria and archaea. The eukaryote has a nucleus membrane that surrounds the nucleus in which the way they defined the

Nucleus – The nucleus is the largest organelle in the cell. It acts as the control system for almost all the activities of the cell. It stores the cell 's hereditary material, or DNA

The cell’s nonmembranous organelles include the cytoskeleton, microvilli, centrioles, cilia, ribosomes, and proteasomes. Membranous organelles include the endoplasmic reticulum, the Golgi apparatus, lysosomes, peroxisomes, and mitochondria.

Prokaryotic: (single cell)The plasma membrane encloses the cell, regulating the traffic of materials into and out of the cell, and separating its interior from the external environment.

There are two main types of cells in the world. The simplest cells such as bacteria are known as Prokaryotic cells, and human cells are known as Eukaryotic cells. The main difference between each of these cells is that a eukaryotic cell has a nucleus and a membrane bound section in which the cell holds the main DNA which are building blocks of life.

The cytosol is also present in the Plant, Animal, and Prokaryotic cells. The cytosol is the thick, gelatin-like liquid in the cell that accounts for almost 70% of its volume. The cytosol of a cell is the substance in which the organelles are suspended and it provides the proper conditions for their function and movement. The cytosol was discovered by Albert Claude, Christian de Duve, and George E. Palade in 1835.

organelles in cells found in a wide range of animals including amphibians, fish, reptiles, crustaceans, cephalopods, and bacteria. Mammals and birds.

P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes.

Cells are the basic components of all living things. Both the prokaryotic and the eukaryotic cell contain a plasma membrane, a cytoplasm, DNA, and ribosomes. One of the main differences between a eukaryotic and prokaryotic cell is that a prokaryotic cell lacks a nucleus, (pro means before and kary means nucleus) and it also lacks membrane-bound organelles. Instead of having a nucleus, prokaryotes have a single chromosome. This chromosome is often referred to as a gonophore. Due to prokaryotes being single celled, the inside of a prokaryotic cell is full of open space, meaning they do not contain any membrane walls. The prokaryotic cell makes up all bacteria and bacteria-like archaea (germs).

The cytoplasm is the area between the nucleus and the cell membrane. The cytoplasm contains many important structures. This area is basically the main place where you will find structures that help the cells stay alive.

Prokaryote cells - bacteria and archeans. They are single celled organisms, where the DNA is not separate from the cytoplasm. These prokaryote cells formed the earliest and most primitive life on earth.

In regards to their basic structure, according to the SEER Training website, “cells consist of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm.” (Training.seer.cancer.gov, 2017) This is true for animal cells however plant cells contain a fourth part which is known as the cell wall, it is located on the outside of the cell membrane and allows the cell to keep its rigid shape. It should also be known that there are types of cells that do not contain a nucleus, these are called prokaryotic cells and generally still have the same characteristics as cells that do have a nucleus which are known as eukaryotic cells. (Study.com, 2017) As seen in Figure 1 cells also contain organelles which keep the cell alive and allow it to function effectively.The cytoplasm of the cell which resides between the cell membrane and the nucleus is a gel-like liquid filling the inside of the cell. The cytoplasm allows the cell to have shape and allows the cell 's organelles to move around the cell as needed and function correctly. The nucleus is widely considered to be the control center or

The cytoplasm is a semifluid in the plasma membrane. It is in all eukaryotic cells. In prokaryotes, this is where the chemical processes of the cell take place. In eukaryotic cells, this is where organelles perform their functions. Cellular respiration also takes place here. One of stages of cellular respiration is glycolysis. Glycolysis is when glucose breaks down to form two pyruvates and 4 ATP. Its net result of 2 ATP is important for another process called the Krebs Cycle. This process is important because it begins cellular respiration. The cytoplasm also gives the cell its shape; without it, the cell would be “deflated” and substances would not be able to move throughout the cell. Organelles would have difficulty functioning too. It has been misunderstood that organelles float freely in the cytoplasm even
