What acts as an intracellular highway?
Endoplasmic Reticulum The ER has two major functions: Transport: Molecules, such as proteins, can move from place to place inside the ER, much like on an intracellular highway.
What is the function of intracellular transport?
Intracellular transport, via membrane-bound carriers, is essential for proper functioning of a cell. It, for instance, delivers newly synthesized proteins via the endoplasmic reticulum (ER) and the Golgi complex to the location where they can perform their function.
What structure mainly function in intracellular transport?
Since intracellular transport heavily relies on microtubules for movement, the components of the cytoskeleton play a vital role in trafficking vesicles between organelles and the plasma membrane by providing mechanical support.
What function is the highway of the cell?
The Rough ER which is studded with ribsomes is needed to carry substances, like proteins, to various parts of the cell. These proteins are delivered to other membrane bound organelles like golgi body or transported out of the cell. Endoplasmic reticulum is regarded as the highway of the cell!
What is the function of the cell membrane?
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
What is cytoskeleton function?
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 intracellular process?
Intracellular refers to the inside region of cells and what you find there. The cell membrane keeps all the organelles of the cell and the cytoplasm contained and allows material to move in and out of the cell. And remember that cytoplasm is simply the stuff that forms the cell.
Which organelle is responsible for intracellular transport Why?
So, the correct answer is ‘Endoplasmic Reticulum’.
What is the intracellular part of cell?
What organelle is an intracellular highway composed of membranous sacs and tubules called cisternae?
A system of membranous tubes and sacs, called cisternae. The ER functions primarily as an intracellular highway a path along which molecules move from one part of the cell to another. Analogy: A waiter at a restaurant. The rough endoplasmic reticulum is a system of interconnected, flattened sacs covered with ribosomes.
What is the nucleus function?
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.
What are the intracellular cargoes of a cell?
A variety of intracellular cargoes, including proteins, RNAs, vesicles, and even entire organelles, can move around inside a cell by this intracellular transportation system. [In this figure] Cytoskeleton consists of three types of filament proteins: microtubules, actins, and intermediate filaments.
What is the function of a highway?
The function of a highway is to provide a facility that allows the movement of vehicles. Different types of facilities are needed for various vehicle travel movements.
What controls the movement of molecules in the cell membrane?
Cell membrane controls the movement of molecules such as water, ions, nutrients, and oxygen in and out of the cell. Proteins on the cell membrane also involved in cell movement and the communication between cells.
What is the function of cell wall?
Cell wall 1 Cell wall is an extra layer of structural support and protection outside the cell membrane of plant cells. 2 Cell wall is made of cellulose, a polymer type of sugars. 3 The structural support of cell walls allows plants to grow to great heights (like pine trees). 4 When Robert C.
