Solution Verified by Toppr Correct option is D) Ethylene is the only gaseous plant hormone. It is also called as ripening hormone as it plays the important role in controlling the fruit ripening. During fruits ripening, the respiration rate in fruits is increased by ethylene.

As we know, one of the important factors in the culture medium is pH such as sucrose inversion during, mineral availability, PGR uptake, root growth, somatic embryogenesis, regeneration,.

Gibberellins are a group of plant hormones responsible for growth and development. They are important for initiating seed germination. Low concentrations can be used to increase the speed.

2.1 Auxins. This group of phytohormones has the ability to induce cell elongation in the subapical region of the stem . Besides this ability, auxins are involved in almost all aspects of plant growth and development such as stem and root elongation, stimulation of cell division, lateral and adventitious root initiation, apical dominance, vascular tissue differentiation, gravitropism and.

The normal range for an animal cell varies from 10 to 30 micrometers while that for a plant cell stretches from 10 to 100 micrometers. Beyond size, the main structural differences between plant and animal cells lie in a few additional structures found in plant cells. These structures include: chloroplasts, the cell wall, and vacuoles.

(v) Plant cells do not have specialized proteins. Movement in our legs (i) It occurs in response to our requirements and is a voluntary action. (ii) Movement in our legs is voluntary action which is controlled by cerebellum part of hind brain. (iiip) Nerves carry the message for movement of legs.

Gibberellin is type of plant and fungal hormone. While its role in fungal development is not as clearly understood, it has been extensively studied in plants. Gibberellin is one of 5 major groups of plant hormones, the others being auxins, cytokinins, ethylene and abscisic acid.

A plant in the laboratory is given an increased dose of a hormone, which promotes the development of seedless fruits. asked Oct 19, 2020 in Biology by Kaanta ( 54.2k points) control and coordination

Cell Walls. All plant cells have cell walls made of cellulose -- this is a defining factor for plant cells. Under a microscope, plant cells from the same source will have a uniform size and shape. Beneath a plant cell’s cell wall is a cell membrane. An animal cell also contains a cell membrane to keep all the organelles and cytoplasm.

A really obvious difference is in the outer shell of the cell. In addition to a cell membrane, plants have cell walls made out of tough compounds called cellulose and lignin, which makes them rigid and tough — useful for keeping trees from collapsing into gelatinous piles of plant tissue.
