When a cell grows its plasma membrane expands does it involve exocytosis or endocytosis please explain?
I believe it's endocytosis, Because the cell takes in the food or the (transport) vesicles to grow " by the three types of endocytosis: Phagocytosis " Cellular eating " Pinocytosis " Cellular drinking " and " Receptor-mediated endocytosis "
And they will fuse with the plasma membrane and become part of it, so accordingly, the plasma membrane is expanding.
What else can I help you with?
Ribosomes-rough endoplasmic reticulum-vesicle-Golgi apparatus- vesicle- within the cell or outside the cell explain where in this pathway the process of exocytosis plays a role?
These are all organelles and all cellular organelles are located within the cell's cytoplasm which is located within the cell. Exocytosis is a process that occurs when vessicles bud off from the golgi apparatus (golgi body) and transport proteins or other cellular materials to the edge of the cell, where they fuse with the cell membrane and excrete the contents into the extracellular space (the space outside of the cell).
Three types of active transport?
Active transport is the process of moving solutes against their electrochemical gradient. This is essential to maintain the intracellular ionic composition of cells and to import solutes that are at a lower concentration out side the cells and to import soultes that are at a lower concentrion outside the cell than inside. (i) Coupled transporters couple the uphill transport of one solute across the membrane to the downhill transport of another. (ii) ATP-driven pumps couple uphill transport to the hydrolysis of ATP. (iii) Light-driven pumps, which ae found mainly in bacterial cells, couple uphill transport to an input of energy from light.Your three types of Active Transport is therefore Coupled Transporters, ATP-driven pumps, and Light-driven pumps.
What is a model used to explain the components and properties of a plasma membrane?
The fluid mosaic model is commonly used to explain the structure and function of the plasma membrane. It describes the membrane as a fluid lipid bilayer with embedded proteins that can move laterally, giving the membrane its dynamic nature. The model helps illustrate how the plasma membrane controls the passage of substances into and out of the cell.
Explain the difference between passive transport and active transport Give several types of each and explain how they work?
when molecule travels from a higher concentration to a lower concentration through a concentration gradient.It is known as passive transport. Active transport refers to when molecule travels from a region of lower concentration to a region of higher concentration against the concentration gradiet. Transport of protein is an active transport. Fit it in the sentence your way
What are the limitations of the Davson-Danielli model of membrane structure?
The Davson-Danielli model of membrane structure is limited because it suggests that membranes are made of a simple sandwich-like structure, which does not account for the dynamic nature of cell membranes and the presence of integral membrane proteins. This model also fails to explain how membranes can selectively allow certain substances to pass through while blocking others.
Explain how endocytosis and exocytosis work?
Endocytosis is when the cell membrane engulfs a particle and brings it into the cell, forming a vesicle. Exocytosis is when particles are expelled, usually from the Golgi apparatus forming vesicles and having it fuse with the surface of the cell.

A large protein needs to enter a cell to help the cell perform a function. Explain what process the cell must use to allow the protein to enter and why.?
The cell must use a process called endocytosis to allow the large protein to enter. This process involves the cell membrane engulfing the protein and forming a vesicle that brings it inside the cell. Endocytosis is necessary for large molecules, like proteins, because they cannot pass through the lipid bilayer of the cell membrane due to their size and polarity. Once inside, the protein can be utilized for various cellular functions.
What model is used to explain the componets and properties of plasma membrane?
The Fluid Mosaic Model is used to explain the components and properties of the plasma membrane. This model describes the plasma membrane as a dynamic structure composed of a lipid bilayer with embedded proteins that can move and interact within the membrane.

Explain the part played by the cell membrane in the movement of substances into and out of the cell?
The correct answer is diffusion. Diffusion is the process by which materials enter and leave a cell through the cell membrane.
What is cell membrane explain in urdu?
plasma membrane is the outer most boundary of animal cell.it is chemically composed of lipids and proteins.it is selectively permeable allow certain materials to move in and out.fluid mosaic modle explain its structure.
The is a model used to explain the components and properties of a plasma membrane?
Fluid-mosaic model
Explain how ice-wedging can weather a rock?
Ice-wedging occurs when water seeps into cracks in a rock, freezes, expands, and widens the crack. As the water repeatedly freezes and thaws, the crack will continue to expand due to the pressure exerted by the ice. Over time, this process can cause the rock to break apart into smaller pieces.
