Means of Transport in Plants

Name the proteins that facilitate the movement of the water across the membrane channel. (Aquaporins/Globulins)

_____ (Aquaporins/Desmosomes) regulate the movement of water across the membrane.

Define aquaporins.

Which of the membrane channels helps in the transport of water in the plants.

Aquaporins only help in the transport of salts in the plant.

The movement of one molecule independent of the other molecules across the cell membrane is known as 

What is the transport of only one molecule, without coupling to the transport of another molecule or ion is called?

Write about uniport means of transport in plants.

Fill in the blank with the correct option provided in the bracket.

The transport process that carries out downhill transportation of molecules like in simple diffusion but involves transport proteins is _____(active transport/osmosis/facilitated diffusion).

Which among the following are common to both facilitated diffusion and active transport.

Differentiate between simple diffusion and facilitated diffusion.

All simple diffusion does not require the involvement of transport proteins, but all facilitated diffusion requires transport proteins for the transportation of substances.

Which among the following statement is correct?

Osmosis is a special kind of diffusion, in which water diffuses across the cell membrane. The rate and direction of osmosis depend upon both pressure gradient and_____.

Name the part of the plant body, which absorbs mineral nutrients.

The porins are_____that form huge pores in the outer membranes of the plastids.

Water channel consists of how many types of aquaporins?

Porins are the lipid molecules that form large pores in the outer membranes of plastids, mitochondria and some bacteria.

Characteristic of ion channels is/are _______.

Explain diffusion pressure gradient.
