What causes apical dominance?
Apical buds are those located at the end of stems; lateral buds are located in the leaf axils along the length of the stems. Apical dominance occurs when a branch tends to get longer and longer without sending off branching shoots. This occurs because of a substance called auxin which is produced in the apical buds and which inhibits growth of stems from the lateral buds.
What would happen if apical meristem is cut in a plant?
Cutting the apical meristem in a plant would result in the loss of apical dominance, leading to lateral buds being activated to grow. This can cause branching to occur from lower parts of the plant, changing its overall growth pattern.
Which hormone is responsible for thickening the endometrium?
the hormone responsible for thickening the endometrium is progesterone.
How is the shoot apical meristem different from the root apical meristem?
The main difference betweem root and shoot apical meristem is that in case of root apical meristem dermatogen and periblem fuses at apex and give rise to calyptrogen which is responsible for the formation of root cap
What hormone is responsible for triggering ovulation in the menstrual cycle?
The hormone responsible for triggering ovulation in the menstrual cycle is called luteinizing hormone (LH).
Which hormone is most involved in apical dominance?
auxin
What do auxin's control?
Auxin is a plant hormone that is involved in many signal processes. It is most commonly talked about in apical dominance

How do you prepare a best project on apical dominance?
To prepare a project on apical dominance, consider researching the factors influencing apical dominance, its importance in plant growth and development, and its practical applications in agriculture and horticulture. Include diagrams or illustrations to explain key concepts, and consider conducting experiments or observations to demonstrate apical dominance in action. Conclude with a summary of the project findings and implications for future research or agricultural practices.
What is the meaning of 'apical dominance'?
Authority or control
Who discovered apical dominance?
Thimann and Skoog in 1934
What plant hormone is Produced mainly in shoot tips and leaves?
Auxin is a plant hormone mainly produced in shoot tips and leaves. Auxin plays a crucial role in promoting cell elongation, apical dominance, and phototropism.
What is the advantages of an apical dominance?
Apical dominance is a phenomenon seen in plants in which a central stem becomes dominant, growing faster than other stems and secreting hormones which inhibit stem growth below the terminal bud at the end of the apical stem. A number of plants and trees exhibitapical dominance, with fir trees being a classic example. The distinctive triangular shape of the fir tree is the result of apical dominance, with the trunk of the tree being the apical stem. There are a number of reasons why plants adopt apical dominance. By pouring energy into a central stem, plants can achieve height quickly, which increases their access to nutrients and also helps the plant block competition. This phenomenon is also exhibited in rooting systems, where apical dominance results in a long, very strong taproot which keeps the plant firmly anchored in place, unlike a fibrous root system, which can make the plant unstable in some soils. The terminal bud on the apical stem secretes the hormone auxin, which blocks growth in lower stems. If it is removed or the circulation is inhibited, other stems below will start to shoot up, and one may in turn become apical. Apical dominance can also be seen in branches; branches which grow from the main stem will in turn inhibit the growth of smaller branches from stems along their length.
What process makes the plant to grow straight to versus spread out?
apical dominance
What hormone or hormones can be used to assist plant growth?
Auxins which promote apical dominance, cell elongation and root growth and gibberilins which stimulate elongation growth.
How does a willow tree sprout from its trunk?
A willow tree sprouts new branches from its trunk through a process called apical dominance, where the growth hormone auxin inhibits the growth of lateral buds until the main shoot is established.
What will happen if apical meristem is damaged or cut?
If the apical meristem is damaged or cut, it may result in a loss of apical dominance, leading to the activation of lateral buds and the development of multiple stems. This can cause changes in the plant's growth pattern and structure.
