Diffusion and Osmosis
Give examples of osmosis and diffusion.
‘Osmosis is a special kind of diffusion’. Comment.
What is the role of water in the process of diffusion?
Explain: Plasmolysis is the process by which a plant cell loses water through hypertonic solutions.
The aroma of food comes from the kitchen because of-(a) Osmosis(b) Diffusion(c) Convection(d) Fragmentation
During respiration, glucose and oxygen enter our body cells and waste products carbon dioxide and water leave the body cells by the process of :(a) effusion (b) osmosis(c) diffusion (d) plasmolysis
Which process in a plant is accomplished by utilising energy from ATP : transport of water and minerals or transport of food ?
Give one example of the movement of a plant part which is caused by the loss of water (or migration of water).
Water and dissolved minerals get into the root hair of a plant by a process called A and enter the conducting tissue B. The process C helps the water and dissolved minerals to move up through the tissue B in roots and stem, and reach the leaves of a plant . In the leaves food is made by a process D. This food is then transported to all the parts of a plant through tissue E. The process of distributing food made in the leaves to all the parts of the plant is called F.(a)What are (i) A (ii) B (iii) C (iv) D (v) E, and (vi) F ?(b) Which tissue is made up of living cells : B or E ?(c) Which tissue, B or E, contains sieve tubes ?(d) Which tissue, B or E, contains tracheids ?
Explain why, the diffusion of a solid in another solid is a very slow process.
