The hormone that is used to keep flowers fresh isa)cytokininb)gibberellinsc)auxind)abscisic acidCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Option (a)---->>
Cytokinins also act in conjunction with auxin (another plant hormone) to retard senescence, which, at least in its early stages, is an organized phase of metabolism and not just a breakdown of tissue.commercially in the storage of green vegetables to reduce yellowing.

Answer

As we know Abscisic Acid do not allow the plants to mature and acts like a growth inhibitor will never keep the plants fresh but destroy them
Gibberellins and Auxin help in plant growth.Auxin is responsible for phototropism and it is a growth hormone present at shoot and root system whereas gibberellins help in development of seed to plant,helps the plant to bear fruits and flower
Finally Cytokinin helps in cell division (mitosis)and helps in maintain the freshness of the plant. Gibberellins and Auxin work under Cytokinin to promote development of the plant

Answer

Cytokinin is essentially known to delay senescence by retarding the rate of destruction and degeneration of chlorophyll molecules and proteins among its various other physiological functions. This process is known as the 'Richmond Lang effect'.

Answer

Answer:

Flowers are living organisms and, like any other living organism, they undergo various physiological processes. One of these processes is the aging and wilting of flowers, which occurs due to the breaking down of cells and loss of turgidity. To prevent this natural process and extend the vase life of flowers, hormones are often used. The hormone that is commonly used to keep flowers fresh is cytokinin.

What are hormones?
- Hormones are chemical messengers that control and regulate various physiological processes in living organisms.
- In plants, hormones play a crucial role in growth, development, and response to environmental stimuli.

What is cytokinin?
- Cytokinins are a group of plant hormones that promote cell division, delay senescence (aging), and maintain the overall health of plants.
- They are naturally produced in the meristematic tissues of plants, such as the roots, shoots, and developing fruits.
- Cytokinins are involved in various physiological processes, including cell division, shoot initiation, and differentiation of vascular tissues.

How does cytokinin keep flowers fresh?
- When flowers are cut from the plant, they lose their connection to the plant's vascular system, leading to a decrease in nutrient and water uptake.
- This loss of water and nutrients affects the turgidity and overall freshness of the flowers.
- Applying cytokinin to the flowers helps in maintaining their turgidity and delaying the natural aging process.
- Cytokinins stimulate cell division, which helps in the formation of new cells and prevents the breakdown of existing cells.
- By promoting cell division and delaying senescence, cytokinins keep the flowers fresh for a longer period.

Other hormones:
While cytokinins are commonly used to keep flowers fresh, other hormones also play a role in flower preservation. These include:
- Gibberellins: They promote stem elongation and can be used to increase the size of flowers.
- Auxin: It regulates growth and development, including the opening and closing of flower buds.
- Abscisic acid: It promotes the closure of stomata and plays a role in plant stress responses.

However, cytokinins are specifically known for their ability to delay senescence and keep flowers fresh, making them a popular choice for flower preservation.
