Differentiate between(a) Racemose and Cymose inflorescence(b) Fibrous root and adventitious root(c) Apocarpous and Syncarpous ovary
(a) Racemose inflorescence and Cymose inflorescence:
Racemose inflorescenceCymose inflorescence
In racemose type of inflorescences the main axis continues to grow.In cymose type of inflorescence the main axis terminates in a flower, hence is limited in growth.
The flowers are borne laterally in an acropetal succession.The flowers are borne in a basipetal order.
(b) Fibrous root and adventitious root:
Fibrous rootAdventitious root
In monocotyledonous plants, the primary root is short lived and is replaced by a large number of roots. These roots originate from the base of the stem and constitute the fibrous root system, as seen in the wheat plant.In some plants, like grass, Monstera and the banyan tree, roots arise from parts of the plant other than the radicle and are called adventitious roots.
(c) Apocarpous and syncarpous ovary:
Apocarpous ovarySyncarpous ovary
When more than one carpel is present, they may be free (as in lotus and rose) and are called apocarpous.They are termed syncarpous when carpels are fused, as in mustard and tomato.
