5. MORPHOLOGY OF FLOWERING PLANTS
Flowering plants display a vast diversity in morphology, including variations in roots, stems, leaves, flowers, fruits, and seeds. The root system can be either tap or fibrous, serving functions such as water absorption and food storage. The flower, a modified shoot for sexual reproduction, can exhibit numerous structural characteristics and inflorescence types, which significantly aid in the classification and identification of plant families.

What we have learnt
- Flowering plants have distinct root and shoot systems, with roots serving to absorb water and provide support.
- The structure of the flower is essential for understanding reproductive processes and varies across species.
- Various vocal terms such as phyllotaxy, placentation, and aestivation describe leaf arrangement and reproductive structures.
Key Concepts
- -- Phyllotaxy
- The pattern of arrangement of leaves on the stem or branch, typically classified as alternate, opposite, or whorled.
- -- Aestivation
- The arrangement of sepals or petals in floral buds, which can be classified into types like valvate, twisted, imbricate, and vexillary.
- -- Placentation
- The arrangement of ovules within the ovary, which can vary among different flowering plants.
- -- Racemose Inflorescence
- An inflorescence type where the main axis continues to grow and flowers are borne laterally in an acropetal manner.
- -- Cymose Inflorescence
- An inflorescence in which the main axis terminates in a flower, limiting further growth.
