Yes, materials that enter the cell by phagocytosis also cross through the cell membrane, but in a different manner compared to passive or active transport. In phagocytosis, the cell membrane engulfs large particles or microorganisms, forming a vesicle that brings these materials into the cell. This process involves the membrane folding around the substance rather than allowing it to pass through like smaller molecules do in passive or active transport.

Name the processes that are involved in the transport of materials in protists?
In protists, the processes involved in the transport of materials include diffusion, active transport, phagocytosis, and pinocytosis. Diffusion allows small molecules to passively move across the cell membrane, while active transport uses energy to move materials against a concentration gradient. Phagocytosis involves the engulfment of solid particles by the cell, while pinocytosis facilitates the uptake of fluids and dissolved molecules.
Process that amoebas use to take in food and other materials?
Amoebas use phagocytosis to take in food and other materials. During phagocytosis, the amoeba extends its cell membrane around the particle and engulfs it, forming a food vacuole. The food is then digested inside the vacuole.
What are five transport mechanism where by metabolites nutrient or ions cross the cell membrane?
There are many forms of membrane and cell transport. These are the basic transport mechanisms in a prokaryotic animal cell. Facilitated Diffusion Osmosis Diffusion Exocytosis (this takes two forms; phagocytosis and pinocytosis depending on whether the cell is "eating" or "drinking") Endocytosis Carrier Molecules/Channel Proteins
Is amoeba engulfing its food an example of active transport?
No, amoeba engulfing its food is not an example of active transport; it is a process known as phagocytosis. During phagocytosis, the amoeba extends its membrane to surround and engulf food particles, forming a food vacuole. This process does not require energy input in the form of ATP, which is characteristic of active transport. Instead, it relies on the movement of the cell membrane and is more of a passive process.
What is the process by which materials are engulfed by the cell membrane and brought into the cell?
The process by which materials are engulfed by the cell membrane and brought into the cell is called endocytosis. It involves the formation of vesicles that surround the material to be taken in and then fuse with the cell membrane to release the contents into the cell. There are two main types of endocytosis: phagocytosis, for larger solid particles, and pinocytosis, for smaller liquid particles.
Phagocytosis pinocytosis and exocytosis are all kinds of what transport?
These are all types of active transport involving the movement of materials across a cell membrane. Phagocytosis refers to the process of engulfing large particles, pinocytosis involves taking in fluids or solutes, and exocytosis is the release of materials from a cell.
Name the processes that are involved in the transport of materials in protists?
In protists, the processes involved in the transport of materials include diffusion, active transport, phagocytosis, and pinocytosis. Diffusion allows small molecules to passively move across the cell membrane, while active transport uses energy to move materials against a concentration gradient. Phagocytosis involves the engulfment of solid particles by the cell, while pinocytosis facilitates the uptake of fluids and dissolved molecules.
What are the two types of active transport?
The two major parts of active transport are endocytosis and exocytosis. Endocytosis is taking material into the cell by means of infoldings in the cell membrane. There are two types of endocytosis: phagocytosis (large molecules) and pinocytosis (small molecules). Exocytosis is the release of materials from a cell. The vacuole membrane and the cell membrane fuse together and the contents are released.
Differentiate phagocytosis and exocytosis?
Phagocytosis is the process by which cells engulf and digest large particles, such as bacteria or cellular debris, through the formation of vesicles called phagosomes. Exocytosis, on the other hand, is the process by which cells release substances stored in vesicles outside the cell by fusing the vesicle membrane with the cell membrane. In phagocytosis, material is ingested, while in exocytosis, material is released.
What are five ways that the membrane can deal with materials?
The cell membrane can deal with materials through several mechanisms: Passive Transport: This includes diffusion and osmosis, where substances move across the membrane without energy input, following their concentration gradients. Active Transport: This process requires energy, usually in the form of ATP, to move substances against their concentration gradients using transport proteins. Endocytosis: The membrane can engulf materials, forming vesicles to bring them into the cell, which includes phagocytosis for solids and pinocytosis for liquids. Exocytosis: This is the process by which cells expel materials by fusing vesicles with the membrane, releasing their contents outside the cell. Facilitated Diffusion: Specific molecules can cross the membrane via protein channels or carriers, allowing selective transport without energy expenditure.

Amoebas use phagocytosis to take in food and other materials. During phagocytosis, the amoeba extends its cell membrane around the particle and engulfs it, forming a food vacuole. The food is then digested inside the vacuole.

A twisted membrane with portions that breakoff to form vesicles that transport materials?
This process is called endocytosis, where the cell membrane invaginates to form vesicles that transport materials into the cell. These vesicles can then fuse with other organelles or transport materials to other parts of the cell.

During phagocytosis, the amoeba extends its membrane to surround and engulf food particles, forming a food vacuole.

What types of materials does osmosis transport?
Osmosis transports water molecules across a partially permeable membrane, such as a cell membrane. It does not transport other types of materials, like ions or larger molecules.
The formation of a pocket of the plasma membrane to bring in solid materials is called?
The process where the plasma membrane forms a pocket to bring in solid materials is called endocytosis. This involves the engulfment of particles by the membrane to create a vesicle inside the cell for further processing.
