Questions Related to guttation
Waste products produced during respiration in plant is/are
-
CO$ _{2}$
-
Water
-
Oxygen
-
Both A and B
- Like animals, plants also respire all the time because their cells need energy, to stay alive, but plants can only photosynthesize when they are in the light. Photosynthesis happens in the chloroplasts of plant cells.
- It produces glucose for use by the plant, and oxygen as a waste product. Respiration uses oxygen and produces carbon dioxide and water as a waste product.
Waste products produced by plants is/are
-
CO$ _2$
-
Water
-
Oxygen
-
All of the above
Oxygen is a waste product of photosynthesis. While carbon dioxide is exhaled by the plants at night in absence of photosynthesis. Excess water is given out by transpiration.
So the answer is- all of these.
The main waste products of plants are
-
CO$ _2$ and NO$ _2$.
-
CO$ _2$ and water vapour.
-
CO$ _2$, O$ _2$ and water vapour.
-
None of the above.
Plants eliminate some waste through diffusion. During the day, excess oxygen gas produced by photosynthesis is released through the stomata. Carbon dioxide produced by respiration is normally used up during photosynthesis. At night, however, as photosynthesis slows, carbon dioxide is not used up as fast as it is produced, and it is released as a waste product. Plants also release waste water by transpiration and guttation.
Plants excrete gases through
-
Microscopic pores in leaves.
-
Small porous roots.
-
Flowers.
-
Seeds.
Plants eliminate some waste through diffusion. During the day, excess oxygen gas produced by photosynthesis is released through the stomata. Stomata are microscopic pores in leaves. Carbon dioxide produced by respiration is normally used up during photosynthesis. At night, however, as photosynthesis slows, carbon dioxide is not used up as fast as it is produced, and it is released as a waste product. Plants also produce oxygen as a by-product of photosynthesis. The oxygen that is not used for respiration is also excreted through the stomata. Plants do not excrete gases through flowers, roots and seeds.

Which one of the following is not related to guttation?
-
Water is given out in the form of droplets
-
Water given out is impure
-
Water is given out during daytime
-
Guttation is of universal occurance
In soil rich in moisture content water floods a plant root system. Leaves can retain only a finite amount of water. Excess water i.e xylem sap from the roots is given out through pores or edge of leaves in the form of droplets. This process is called guttation. As this water contains different organic and inorganic substances from the plant it is considered impure. Also, guttation is of universal occurrence. Thus the correct answer is option C.
Which condition favors guttation?
-
High humidity
-
Low humidity
-
More transpiration
-
Bright sunlight
Guttation is the phenomenon of the release of small water droplets from the pores of the plants. It is done in order to release the extra water out of the plant in very humid conditions. It is commonly seen in mesophytes.
Loss of water from tips of leaves is
-
Transpiration
-
Guttation
-
Bleeding
-
Respiration
