Ethylene
auxins are group of related chemical substances which activity greatly affect the physiological processses in plant and animal.auxins helps in stimulating plant growth and also hasten fruit ripening.
Ethylene is a plant hormone that can trigger the ripening of fruits, senescence of leaves, and flower wilting. In flowers, exposure to ethylene can lead to premature wilting, petal discoloration, and overall shorter vase life. Proper management of ethylene exposure is important to maintain the freshness and longevity of cut flowers.
Plant responses to ethylene include fruit ripening, leaf and flower senescence (aging), and abscission (shedding) of leaves and flowers. Ethylene can also induce the opening of stomata, which are tiny pores on the surface of leaves that regulate gas exchange.
flowers an leaves
A Cactus - it has a modified stem which produces flowers, but no leaves.
A Rose has leaves and flowers.
Usually stems hold flowers, leaves, and fruit on plants.
They are modified leaves
Determinate growth occurs when leaves and flowers grow to a set size.
The plant hormone ethylene inhibits abscission, which is the process of shedding leaves, flowers, or fruits in plants. Ethylene plays a key role in the regulation of various physiological processes in plants, including senescence and fruit ripening.
Above ground system in plants consists of stem, leaves and flowers.
