Which of the following shows the correct relation at atmospheric pressure?

When a seed is soaked overnight in water, what happens to its cells?

When rajma seeds are soaked in water overnight, they swell. What gives the explanation for this?

Which of the following is a characteristic of mass flow movement?

Mention the type of molecular movement which is highly selective and also requires special membrane proteins, but works without the requirement of energy.

Why does the rate of transport reach maximum or become saturated in facilitated diffusion?

Passive transport across a membrane, when two protein molecules move in opposite direction and independent of each other, is called as 

Mention one similarity between transport proteins and enzymes proteins.

Give one basic difference between antiport and uniport

What are the different factors that affect the rate of diffusion?

What are proteins? what role do they play in diffusion?

Mention two factors on which net direction of molecules and rate of osmosis depends

Why is osmotic potential given a negative sign?

Enumerate the importance os osmosis in the life of the plants. (any two points)

Various types of transport mechanisms are needed to fulfil the mineral requirements of a plant. Why are they not fulfilled by diffusion alone?

Briefly, describe water potential. what are at the factors affecting it?

What happens when a pressure greater than the atmospheric pressure is applied to pure water or a solution?

Name the two theories which explain water movement in stems.Give the explanation of root pressure theory.

Enumerate the process of guttation.How is it affected by root pressure?
