<span>The hormone which is being produced under a water-deficit condition which triggers a drought response is known as Abscisic Acid or ABA.

Abscisic acid is termed as a plant hormone. The main functions in the development of plants include
1. Stomatal closure.
2. Control of organ size.
3. Bud dormancy.
It responds to environmental stresses in plants, which include heat stress, freezing tolerance, cold tolerance, soil salinity, and drought.</span>

Answer:

Abscisic acid

Explanation:

Abscisic acid (ABA) is a plant hormone, which is produced by plants during stress conditions, such as drought (water-deficit conditions), thus, also known as stress hormone.

In dry conditions, it reduces water loss from plant leaves by reducing the rate of transpiration. ABA causes alteration in the osmotic pressure of stomatal guard cells of leaves. It leads to shrinking and closing of stomata, due to which transpiration is reduced.

Thus, the correct answer is 'abscisic acid.'

In biology, the level of organisation from simplest to complex level can be summarized as:

Organelles → cells → tissues → organs → organ systems → organisms → populations →communities → ecosystem → biosphere.

It is clear that tissue is organization level that exists between cells and organs.

When similar cells are assembled together to perform specific function, the assembly or this organization is said to be the tissue.

There can be different types of tissues such as muscle tissue, nerve tissue et cetera.

Similarly, tissues arrange themselves to carry out specific function in the form of organ.

For example, heart is made up of cardiac tissue.

ahrayia [7]

Answer:

<u>Isotonic</u>

Explanation:

If the solute concentration of the cell and that of its surrounding medium are the same there will be no net flow of water in either directions. In this case, the external solution is said to be isotonic to the cell.

Both the cytoplasm concentration and the glucose in the test tube are the same.
