Multiple choice botany transpiration guttation excretion in plants long distance transport of water

The process of water exudation through the hydathode is called as

  1. Guttation

  2. Transpiration

  3. Excretion

  4. Hydrolysis
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Guttation is the loss of water in  the form of liquid through hydathodes or water stomata. It occurs due to positive root pressure and serves to remove excess water from the plant. As xylem sap is having dissolved minerals, water droplets that ooze out from them contain solution of water and minerals.

If the absorption is more and transpiration is less then process affected will be

  1. Root pressure

  2. Guttation

  3. Bleeding

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Transpiration is defined as loss of water as gas or vapour from leaves through the stomatal pore. If there is less transpiration due to high atmospheric humidity and the soil is well watered; there will be an increase in root pressure. The increased root pressure leads to oozing out of the solution of minerals from hydathodes (called as guttation) and other openings (called as bleeding). Thus, the correct answer is option D.

The process involved in the formation of toddy is

  1. Guttation

  2. Transpiration

  3. Bleeding

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Toddy refers to fermented palm wine. It is prepared by fermentation of sap obtained from palm trees. The process of obtaining sap from trees is through bleeding of plant. The sap is extracted and collected by a tapper. Typically the sap is collected from the cut flower of the palm tree. A container is fastened to the flower stump to collect the sap. The white liquid, that initially collects tends to be very sweet and non-alcoholic before it is fermented.

Which one is not related to transpiration?

  1. Regulation of plant body temperature

  2. Absorption and distribution of mineral salts

  3. Circulation of water

  4. Bleeding
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Bleeding takes place through injured organs of the plant. It usually describes fluid oozing from injured plant parts. Transpiration describes the loss of water in vapour form and helps in cooling of leaf surface as well as the movement of mineral ions in transpiration stream. Transpiration is primarily responsible for uptake of water circulating in plant's xylem vessels and tracheids.

Oozing out of water drops from injured edges or tips is

  1. Bleeding

  2. Guttation

  3. Transpiration

  4. Oozation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Oozing out of water drops from injured edges or tips in plants is called bleeding. Bleeding usually develops because of the pressure of sap inside of the tissues which conducts water and sugars around the plant. If any positive pressure exist in the xylem due to any cut or opening results in the exudation or bleeding of the solution from the trachery elements.

So, the correct answer is option A.

Oozing of water drops from injured leaf edges is

  1. Bleeding

  2. Guttation

  3. Transpiration

  4. Translocation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

When water oozes out from the pores of the plants known as Hydathodes then it is known as Guttation.

When water vapour is released from the stomata then the process is known as transpiration .
When the water oozes out from injured leaf edges then it is known as bleeding. 
So the correct answer is 'Bleeding'.
