EXCRETORY PRODUCTS AND THEIR ELIMINATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In Plants, CO2 and water are excreted resp. by
A
Transportation; Excretion
B
Transpiration; Leaf
C
Stomata; Transpiration
D
Vacuoles; Transportation
Explanation: 

Detailed explanation-1: -Oxygen released during photosynthesis is used for respiration while carbon dioxide released during respiration is used for photosynthesis. Excess of water is also excreted from the plant body through the stomatal pores and from the surfaces of fruits and stems.

Detailed explanation-2: -Plants remove carbon dioxide and oxygen by vapour through the stomata, this process is called transpiration. Thus waste gaseous products or plants are carbon dioxide and oxygen.

Detailed explanation-3: -Excretion is carried out in the plants in the following ways: The gaseous wastes, oxygen, carbon dioxide, and water vapor are removed through the stomata of leaves and lenticels of stems. Some waste products collect in the leaves and bark of trees. When the leaves and bark are shed, the wastes are eliminated.

Detailed explanation-4: -Transpiration is the evaporation of water from plants occurring at the leaves while their stomata are open for the passage of CO2 and O2 during photosynthesis.

Detailed explanation-5: -Stomata have two main functions, namely they allow for gas exchange acting as an entryway for carbon dioxide (CO2) and releasing the Oxygen (O2) that we breath. The other main function is regulating water movement through transpiration.
