In Class 11 Biology (Morphology of Flowering Plants), the arrangement of flowers on the floral axis is called 'Inflorescence'. There are two main types: Racemose and Cymose. Let's study the Racemose Inflorescence.
Inflorescence: The arrangement of flowers on a plant stem.
Racemose Main Axis: Never stops growing.
Acropetal Order: Old flowers at the base, new buds at the tip.
In a Racemose inflorescence, the main axis (the central stem) continues to grow endlessly and does not terminate into a flower. Instead, the flowers are born laterally (on the sides) of the growing stem.
Acropetal Succession:
Racemose inflorescence is an arrangement where the main stem continues to grow endlessly, and flowers grow on the sides in an acropetal succession (older flowers at the bottom, younger buds at the top).
Differentiate Between Active and Passive Immunity
Understand the crucial differences between active immunity (like vaccines) and passive immunity (like maternal antibodies or antivenom).
Acute Febrile Illness (AFI) — Definition, Causes and Diagnosis
Acute Febrile Illness (AFI) is a fever of ≥38°C with acute onset, without an obvious cause. Common causes: malaria, dengue, typhoid, influenza. Full clinical overview.
Adamsia: Classification and Symbiosis
Learn about Adamsia (Sea Anemone) from the phylum Cnidaria. Understand its fascinating symbiotic relationship with hermit crabs.
ADP Full Form — Adenosine Diphosphate in Biology
ADP full form is Adenosine Diphosphate. ADP + Pi → ATP (phosphorylation). ADP is the energy-depleted form of ATP. Structure, function and ATP-ADP cycle explained.
