Movement of cell against concentration gradient is called
osmosis
active transport
diffusion
passive transport
Answer: Option
Explanation:
Active transport, this is the only transport method that can move species against their concentration gradient (from low to high concentration). Facilitated diffusion only moves species down their concentration gradient from high to low concentration.

The answer is active transport due to the use of energy that's why it is against a concentration gradient.

Sometimes, the movement of the cell can cause the highest concentration of cell inside the metal plasma cells.

@Ravi.

Osmosis is the movement of water from higher concentration level to lower concentration level whereas active transport is the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.

What is the difference between osmosis and active transport?

Samuel said:   9 years ago
The right answer is active transport and not osmosis.

I thought that this is mainly corporation in our system.

I Think it is active transport because osmosis occur in fluid contents or in water but it is too different over here. Due to that I am thinking it is active transport.

Osmosis is a kind of passive transport. It takes place down the concentration gradient. Similarly diffusion, facilitated diffusion, filtration are also kind of passive transport. The different is osmosis generally means movement of water molecule. Above they mentioned movement of cell against concentration gradient. Osmosis generally occurs in blood cells so it is correct.

Osmosis is the movement of water molecule from higher level to lower level, active transport is the movement of cell to give nutrient to plant.

Why answer is active transport?
