Question
State two processes through which plants excrete their metabolic wastes
Solution
Plants excrete their metabolic wastes primarily through two processes:
-
Transpiration: This is the process through which water is moved from the roots to the leaves of the plant, where it is then evaporated into the atmosphere. This process helps to carry away waste products from the plant's metabolic activities.
-
Guttation: This is the process through which plants excrete water and waste products from their leaves. This usually happens at night when the plant's stomata (small openings in the leaf surface) are closed and the plant is not transpiring. The water and waste products are forced out of the plant through special structures called hydathodes.

Plant use completely different process for excretion as compared to animals. Which one of the following process is not followed by plant for excretion?AThey can get rid of excess water by transpirationBThey selectively filter toxic substance through their leavesCWaste products are stored as resins and gums in old xylem.DThey excrete waste substance into the soil around them
Excretion is an important process in both plants.Below is a list of processes that occur in plants.1. Flowering plants release chemicals that attract pollinators.2. Auxins that are produced in apical cells diffuse to the area of elongation.3. Carbon dioxide produced during respiration diffuses out of leaves via stomata.4. The common reed Phragmites australis releases acid from it's roots to destroy competing species.5. Excess chlorine and heavy metals are transferred to cells in the leaves. These substances are lost when the leaves fall by abscision.Which of the processes above are examples of excretion?Question 3Select one:A.3, 4 and 5B.Only 3 and 5C.2, 3 and 4D.3 only
