Write the difference between imbibition and osmosis. Why these are important for
plant growth and development?
Answers
☆Imbibition is the process of water absorption through a solid substance, whereas, osmosis is the process of movement of water from higher concentration to lower concentration through a semi-permeable membrane.
☆The growth of plant body: Osmosis indirectly helps in cell division by creating turgidity which results from the growth of the plant body.
☆Imbibition is the first step of water absorption. It facilitates water absorption by roots and helps in the seed germination.
Difference between imbibition and osmosis are as follows.
Explaination:
1. Imbibition is the absorption of water by
solid surface due to difference in
concentrations gradients
2.In osmosis ,water moves from high
concentration gradient to low
concentrations gradient till equilibrium
attained through semi permeable
membrane.
Both are important to plant growth and development as.
1. Seed absorb water due to imbibition and
develop into plants.
2. Cells loses or gain water when placed in
external environment due to osmosis.
