What organelle do plants have that functions in a similar way to a contractile vacuole and helps to prevent the cell from becoming destroyed in hypotonic environments? Explain how it works.

Answers

Answer:

CELL WALL

Explanation:

Plants can prevent their cells from becoming destroyed when placed in hypotonic environment through the help of the rigid cell wall surrounding the cells.

Hypotonic solution is a solution of lower solute concentration that is they are rich in solvent molecules such as water. The rigid cell wall provides a form of pressure called tugor pressure as a result of the action of the pressure pushing against the cell wall from the swelling of the cell. For instance, when a plant cell is exposed to an hypotonic solution, water enters into the cells and the cell swells, instead of the cell exploding, the rigid cell wall prevents that from happening.

The rigid cell wall of plants consist of polysaccharides cellulose, pectins and other strong materials and these help the plant to withstand varying internal osmotic pressures from hypotonic environments.

What is DNA complementarity?

DNA complementarity may be defined as the process through which demonstrates the resemblance of DNA bases in the double helix such that adenine in one strand is opposite thymine in the other strand and cytosine in one strand is opposite guanine in the other.

The mechanism of DNA complementarity also explains the principle of Chargaff's rule. It states that the amount of adenine equals to the amount of thymine while the amount of cytosine equals to the amount of guanine.

According to Watson and Crick, DNA consists of two strands with complementary pairs of nucleotides. One strand is a template to the synthesizing strand which forms complementarily with respect to the template or parental strand.

Therefore, the matching of each strand of DNA with its complement is well described above.

When red light strikes certain cones, they excitea particular bipolar cell. When green light strikes the same cones, they inhibitthe bipolar cell. This observation supports which theory

Answers

Answer:

The correct answer is : The opponent process theory

Explanation:

The opponent process theory states that one color of the color pair dominant over the other color and suppresses it. German physiologist Ewald Hering proposed it for the first time in late 18th century.

The opponent process theory of color vision suggests that our ability to perceive color is controlled by three receptor complexes with opposing actions. According to this theory the human eye perceive color is regulated by the 3 antagonist or opposing systems or channels in the eye.

For example, when red color hits the specific region of cones it activates the specific bipolar cells but when the cones stroked by the green color the bipolar cells are inhibited due to the members of different color channel or pair.

Thus, the correct answer is : The opponent process theory
