Good notes can you send me in my whatspp number

Answer

When young flowers arise from base of plant is known as basipetal order and if the flowers arise from tip then known as acropetal order.

Answer

Acropetal Order in Inflorescence:
Acropetal order in inflorescence refers to the arrangement of flowers on the main axis in such a way that the youngest flowers are present at the apex or top of the inflorescence, while the older or mature flowers are located towards the base. In other words, the flowers open in succession from the bottom to the top of the inflorescence.

Basipetal Order in Inflorescence:
Basipetal order in inflorescence is the opposite of acropetal order. It refers to the arrangement of flowers on the main axis in such a way that the youngest flowers are located at the base or bottom of the inflorescence, while the older flowers are present towards the apex or top. In this case, the flowers open in succession from the top to the bottom of the inflorescence.

Differences between Acropetal and Basipetal Order in Inflorescence:
1. Arrangement of Flowers:
- Acropetal Order: The flowers are arranged in a sequential order, with the youngest flowers at the top and the older flowers at the bottom.
- Basipetal Order: The flowers are arranged in a sequential order, with the youngest flowers at the bottom and the older flowers at the top.

2. Direction of Flower Opening:
- Acropetal Order: The flowers open in succession from the bottom to the top of the inflorescence.
- Basipetal Order: The flowers open in succession from the top to the bottom of the inflorescence.

3. Growth Pattern:
- Acropetal Order: The growth of the inflorescence proceeds in an upward direction, with the apex being the active growing point.
- Basipetal Order: The growth of the inflorescence proceeds in a downward direction, with the base being the active growing point.

4. Examples:
- Acropetal Order: Examples of acropetal order inflorescences include raceme, spike, and panicle.
- Basipetal Order: Examples of basipetal order inflorescences include corymb, umbel, and capitulum.

Conclusion:
Acropetal order and basipetal order in inflorescence are two different arrangements of flowers on the main axis. Acropetal order has the youngest flowers at the top and the older flowers at the bottom, with flower opening proceeding from bottom to top. Basipetal order has the youngest flowers at the bottom and the older flowers at the top, with flower opening proceeding from top to bottom. Understanding these orders helps in identifying and classifying different types of inflorescences.
