Animal Cell – Definition, Structure, Parts, Functions and Diagram

Definition of animal cell Animals are a large group of diverse living organisms that make up to three-quarters of all species on earth. With their ability to move, to respond to stimuli, respond to environmental changes and adapt to different modes of feeding defense mechanisms and reproduction, all these mechanisms are enhanced by their constituent … Read more Animal Cell – Definition, Structure, Parts, Functions and Diagram

Cytoskeleton- Definition, Structure, Functions and Diagram

Cytoskeleton

Cytoskeleton Definition The cytosol of cells contains fibers that help to maintain cell shape and mobility and that probably provide anchoring points for the other cellular structures. Collectively, these fibers are termed as the cytoskeleton. The cytoskeleton gives cells structure and shape and allows them to move around. It’s also important for intracellular transport.  At … Read more Cytoskeleton- Definition, Structure, Functions and Diagram

Microfilaments- Structure and Functions

Microfilaments Definition Microfilaments, also called actin filaments, are polymers of the protein actin that are part of a cell’s cytoskeleton. They are long chains of G-actin formed into two parallel polymers twisted around each other into a helical orientation with a diameter between 6 and 8nm. Common to all eukaryotic cells, these filaments are primarily … Read more Microfilaments- Definition, Structure, Functions and Diagram
