Question

disadvantages of transpiration

Answer 1

DISADVANGAGES OF TRANSPIRATION ARE :-

1⃣WILTING: When the amount of water lost through transpiration exceeds absorption through roots, leaf cells becomes flaccid causing wilting plant wilt, but regain their turgidity in the evening When wilting persisting for a long time, it is called PERMANENT WILTING. Sometimes, it may be due to diseases also.

2⃣STUNTED GROWTH: Excessive transpiration results in the closing of Atlanta following the production of abscissic acid. It causes premature leaf fall and delayed flower production.

3⃣ENERGY EXPENDITURE: Most of the water absorbed is lost by transpiration and energy is utilised in transpiration so it is a gross energy expenditure.

4⃣ABSCISSION: When very little water is available to plants, transpiration results in the closing to Atlanta following resultsvin thevclosingvof stomata following the production of abscissic acid. It causes premature leaf fall and delayed flower production.

5⃣LOSS OF MINERALS: Transpiration stream is the path of movement of minerals sap through the vessels and trachea of xylem tissue, due to transpiration.

Answer 2

Disadvantages of transportation in plant are :-

Excess of transportation in plants cause the death of tissue or cell of the plant due to intense heat of the sun which plant doesn't capable to absorb sometimes plants may died .

Transportation in plant must be in order of equilibrium that is neither more nor less ( the absorbed water from the body parts of plant must be more then transpiration of water ) otherwise due to loss of water ( phenomenon called plesmolysis by which resines is made ) the plant died .
