The Diagram of Animal Cells

All species of large complex organisms are eukaryotes, including plants, animals and fungi. Eukaryotes are organisms whose cells contain complex structures enclosed with membranes, having a nucleus and other membrane-bound organelles. Even though all cells share the main components of the cell and other organelles, they also have distinctive features that differentiate them. Unlike plant cells, animal cells do not have cell walls and chloroplasts, which leads to the lack of a rigid cell wall. This causes the cells of animals to adopt a wide array of shapes. The aforementioned membrane-bound organelles are tiny cellular structures that have different functions, each one being necessary for normal cellular operation. In order to better understand how these cells work, here is some information on the animal cell diagram.

A typical animal cell contains centrioles, cytoplasm, endoplasmatic reticulum, Golgi complex, lysosomes, microtubules, mitochondria, nucleus, nucleolus, nucleopore, and ribosomes. Centrioles have the role of organizing the assembly of microtubules during cell division. The cytoplasm is a gel-like substance within the cell which holds the organelles together. The endoplasmatic reticulum consists of an extensive network of membranes made of regions with ribosomes and regions that do not have ribosomes. The Golgi complex (or apparatus) is in charge of manufacturing, storing and shipping certain cellular products, so it has an important role in the cellular digestion. Lysosomes are enzyme sacs that digest macromolecules such as nucleic acids. Microtubules are also meant to help support and shape the cell. Mitochondrias are power producers in charge of cellular respiration. The nucleus is the membrane bound structure where the cell’s hereditary information is being held, meaning the structure which contains the cell DNA. It is also the central and largest part of the cell. The nucleolus is the structure within the nucleus that has an important role in the synthesis of ribosomes. The nucleopore is a small hole within the membrane which is responsible for allowing nucleic acids and proteins to move in and out of the nucleus. Ribosomes consist of RNA and proteins and are in charge of protein assembly.

As you can see in the cell diagram, these are the components of typical animal cells. Other structures that an animal cell may contain include peroxisomes, the cytoskeleton, cilia and flagella. The animal cell diagram can help both teachers and students, since it enhances the learning and better understanding of animal cells, which are the basic units of every single eukaryote organism.
