Attached, or bound, ribosomes are found on the exterior of an organelle called the endoplasmic reticulum. Because the ribosomes give the organelle a lumpy appearance, the ribosome-containing portion is called the rough ER. Bound ribosomes also translate mRNA for proteins which will be moved outside the cell. …
Q. Is cytoskeleton found in animal or plant cells?
Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

Q. What structures of the cytoskeleton are found in animal cells?
Three major types of filaments make up the cytoskeleton: actin filaments, microtubules, and intermediate filaments. Actin filaments occur in a cell in the form of meshworks or bundles of parallel fibres; they help determine the shape of the cell and also help it adhere to the substrate.
Q. Which part of the cytoskeleton is only found in animal cells?
Centrioles
Q. Is cytoskeleton found in plant cell?
Virtually all eukaryotic cells, including plant cells, have a cytoskeleton. Cytoskeletal systems extend internally from the membrane covering the cell surface to the surface of the membrane system surrounding the cell’s nucleus.
Q. Where do proteins made on free ribosomes go?
Overview of protein sorting. In mammalian cells, the initial sorting of proteins to the ER takes place while translation is in progress. Proteins synthesized on free ribosomes either remain in the cytosol or are transported to the nucleus, mitochondria, (more…)
Q. How many binding sites does a ribosome have?
Three
Q. What is sER and RER?
The smooth endoplasmic reticulum (SER) is distinguished from the rough endoplasmic reticulum (RER), the other basic type of endoplasmic reticulum, by its lack of ribosomes, which are protein-synthesizing particles that can be found attached to the outer surface of the RER to give the membrane its “rough” appearance.
Q. Does protein synthesis occur in rough ER?
Rough endoplasmic reticulum (RER), series of connected flattened sacs, part of a continuous membrane organelle within the cytoplasm of eukaryotic cells, that plays a central role in the synthesis of proteins. …
