They are paired tube-like organelle composed of a protein called tubulin. Centrioles are about 500nm long and 200nm in width that are found close to the nucleus and helps in cell division. They are also found in cilia and flagella.
Also known as the ‘microtubule-organizing center‘ of the animal cells, they are made up of two centrioles, linked together by interconnecting fibers. The centrosomeis similar to DNA, where one centrosome from each parent cell is transferred to the daughter cell.
They are small membrane-bound organelles, filled with hydrolytic enzymes that can break down biomolecules such as carbohydrates, fats, and proteins. The size oflysosomes varies among different cell types, with the largest ones measuring more than 1.2 μm.
It is the outermost membrane of an animal cell having a thickness of 5-10 nm that separates the interior of the cell from outside. The cell membraneis selectively permeable in nature, consisting of a lipid bilayer with proteins, glycolipids, and cholesterol attached to them in a specific pattern.
Protecting the integrity of the cell from the outside environmentAllowing selective entry and exit of substances in and out of the cellMaintaining the shape of the cellProviding mechanical support to the cellIt is a continuous membrane-bound organelle, that remains distributed throughout the cytoplasm and forming connections between nuclear envelope and the cell membrane. There are two types of ER: rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER). The surface of RER is studded with ribosomes, which gives it a rough appearance, w...
Also known as the Golgi body or Golgi complex, it is a series of five to eight cup-shaped, membrane-covered sacs called cisternae. They receive proteins and lipids from RER, which are then modified, sorted, packaged, and transported to their destination.
They are a network of rod-shaped proteins called actin that forms a part of the cell cytoskeleton. Microfilamentsare the thinnest of all the cytoskeletal filaments, having a diameter of about 6-7 nm.
They are hollow tubes composed of the protein tubulin. They are the largest of all cytoskeletal filaments, measuring about 24 nm in thickness.
They are elongated fibrous proteins forming a coiled-coil structure. Intermediate filaments have a diameter of 8-10 nm that are intermediate in size compared to the other two cytoskeletal elements. Microtubules, together with microfilaments and intermediate filaments, complete the cytoskeleton of the cell.

Apr 5, 2024 · The animal cell diagram depicts the various parts and structures within a cell, including the Nucleus, Cytoplasm, Cell Membrane or Plasma Membrane, Mitochondria, Endoplasmic Reticulum, Golgi apparatus, and many more.
There are 12 main components of an animal cell: The Cell Membrane. The cell membrane is the outer edge of the cell and forms the boundary between the inside of the cell with all of its organelles and the extracellular matrix.

May 9, 2023 · An animal cell lacks a cell wall or chloroplasts. Its outer coating is a semipermeable cell membrane. Animal cells are the fundamental units of life in protozoa and multicellular animals. Each cell is a wonder in its own right, plus they work together as building blocks for tissues, organs, and organ systems.
Oct 19, 2020 · Definition. Animal cells are the basic unit of life in organisms of the kingdom Animalia. They are eukaryotic cells, meaning that they have a true nucleus and specialized structures called organelles that carry out different functions.
