Does dissolved minerals enter into the root hair by osmosis not by diffusion?
Dissolved minerals primarily enter root hairs through the process of active transport, where the plant expends energy to move minerals against their concentration gradient. This is a primary mechanism for absorbing essential nutrients such as nitrogen, phosphorus, and potassium. Osmosis and diffusion play a role in water uptake and movement within plant tissues but are not the main routes for mineral absorption.
When a potassium ion K plus moves from the soil into the vacuole of a cell on the surface of a root it must pass through several cellular structures what correctly describes the?
The correct description is that the potassium ion K+ enters the root cell through the plasma membrane by facilitated diffusion or active transport. It then moves through the cytoplasm and finally enters the vacuole by active transport using membrane transport proteins.
Is water a passive diffusion or facilitated diffusion or active trensport or phagocytosis?
Passive diffusion. Water moves from an area of high concentration to an area of low concentration. It is not facilitated diffusion, as it does not require transport proteins to assist it's movement. It is not active transport because it is not moving to an area of higher concentration, and it does not require enzymes or energy to move. Phagocytosis is also incorrect because it is when large particles are "enveloped" by the cell membrane of a larger cell and taken into the larger cell.
Is the final equilibrium state the same for a molecule that enters by facilitated diffusion as for one that enters by diffusion?
Yes
How is most glucose transported into cells?
Passive transport is the kind of movement Êwhen glucose enters a liver cell through a protein channel. It does not require an input of chemical energy being driven by the growth of entropy in the system.Ê
How does a cell control what enters and leaves?
A cell controls what enters and leaves through its selectively permeable cell membrane. This membrane allows only specific molecules to pass in and out through various mechanisms like active transport, passive transport, and facilitated diffusion. Additionally, the cell may use protein channels or pumps to regulate the movement of substances in and out of the cell.
What is the process by which oxygen enters the blood in the capillaries that surround the alveoli?
my guess is facilitated transport so since anyone could write anything on here weather is wrong or not. i decided to show ya.CORRECT ANSWER IS:Diffusionfacilitated transport is wrong
Does glucose enters a cell most rapidly by facilitated diffusion?
No, glucose enters a cell most rapidly through facilitated diffusion with the help of glucose transporters, such as GLUT proteins. Facilitated diffusion allows glucose to move down its concentration gradient into the cell without requiring energy.
What happens after oxygen from air enters the lungs?
after the oxygen from the air enters the lungs,the oxygen gets sent to the heart and then travels through the arteries with the blood.
What is the process called that allows materials to enter or leave a cell?
There are two different types of transport in which materials enter and exit a cell.Active TransportIon pumps - push molecules in and out of the cell against the concentration gradientEndocytosis - the cell membrane forms an envelope around the material and the material enters the cellExocytosis - the opposite of endocytosis, where materials exit the cell. This most frequently occurs in secretory cells (e.g. to create saliva, sweat, proteins, chemicals)Pinocytosis - is exocytosis, but where liquids are taken in to the cellPassive TransportDiffusion - gases diffuse across the membrane with the concentration gradientOsmosis - diffusion of water across the membrane with the concentration gradientFacilitated diffusion - diffusion, but the rate is increasedPassive transport requires no energy expenditure by the cell. Active transport does, and is why cells make energy.I hope this helps :)
What process the cell must use to allow the protein to enter and why?
The process the cell must use to allow the protein to enter is rather simple and uncomplicated. The cell uses the process of osmosis and diffusion along a concentration gradient to allow for passage in and out of the cell.
