What does the rough endoplasmic reticulum do?
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
What is the function of a cytoplasm?
The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.
What is the function of the cytoskeleton?
The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.
What is the function of rough endoplasmic reticulum quizlet?
Function: Rough endoplasmic reticula are involved in the synthesis of proteins.
Why are there ribosomes on the rough ER?
Rough ER is named for its rough appearance, which is due to the ribosomes attached to its outer (cytoplasmic) surface. The ribosomes on rough ER specialize in the synthesis of proteins that possess a signal sequence that directs them specifically to the ER for processing.
What is cytoplasm very short answer?
cytoplasm, the semifluid substance of a cell that is external to the nuclear membrane and internal to the cellular membrane, sometimes described as the nonnuclear content of protoplasm. In eukaryotes (i.e., cells having a nucleus), the cytoplasm contains all of the organelles.
What happens if the cytoplasm malfunctions?
Cytoplasm also helps to move things around in the cells such as hormones and dissolves any cellular waste that may occur. If a cell would be without cytoplasm it could not retain its shape and would be deflated and flat. The organelles would not stay suspended in the solution of a cell without the support of cytoplasm.
What is the role of cytoplasm in nucleus?
The primary component of the protoplasm is the cytoplasm which is situated between the nucleus and the cell membrane in the eukaryotic cells. It contains all the organelles. It regulates the environment of the cell and maintains the cell shape.
Is cytoskeleton prokaryotic or eukaryotic?
Initially, it was thought that the cytoskeleton was exclusive to eukaryotes but in 1992 it was discovered to be present in prokaryotes as well. This discovery came after the realization that bacteria possess proteins that are homologous to tubulin and actin; the main components of the eukaryotic cytoskeleton.
What happens when the cytoskeleton malfunctions?
Consequently, defects in cytoskeletal structures lead to various diseases, including cancer and neurological disorders. Different cytoskeletal systems do not function in isolation, but collaborate with each other in cells.
