Question

1 i) Define diffusion and osmosis. Which of these happen in the following cases?
a) Aquatic organisms using oxygen dissolved in water during respiration
b) Swelling up of deshelled egg on keeping in water
ii) Describe the structure of golgi apparatus.

Answer 1

Answer:

Answer-1){1}Diffusion- The movement of a substance from the higher concentration to lower concentration is known as diffusion.

Osmosis- The movement of a water molecules through the selectively permeable membrane is known as osmosis.

(a) aquatic organisms use oxygen dissolved in the water during the respiration (✓).

{2} Golgi apparatus is discovered by the camillo Golgi. The structure of gogli apparatus is made to store things.

Hope this helps you

Answer 2

Answer:
