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

State two processes through which plants excrete their metabolic wastes

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

Select the correct statementa. During photosynthesis, oxygen is considered as an excretory product by plantsb. Stomata present are present in large numbers in the upper epidermis, that help in transpirationc. Lenticels in the leaves are specialized to eliminate oxygen, water and carbon-di-oxide.d. Resins, gums and ageing leaves are some ways by which plants excrete their waste products.only a,bonly b,donly a,donly c,d

Most of the gaseous exchange that occurs in a plant happens in what organ?

The process in which loss of water in the form of vapour from the aerial parts of plants takesplace is X which helps in Y. Here X and Y respectively are :(a) Transpiration and photosynthesis(b) Transpiration and temperature regulation(c) Translocation and movement of soluble products of photosynthesis in phloem(d) Translocation and absorption of water and minerals from soil by roots
