9. Morphology of Flowering Plants - part 04 -INFLORESCENCE


Inflorescence :

  • A specialised axis or branch over which flowers are produced or borne in definite manner is known inflorescence. 
  • Inflorescence has two parts Penduncle and flowers. 
  • All the flowers do not mature at same time. Chances of pollination increase and large number of flowers can be pollinated in single visit also makes the plant attractive.



Types of inflorescence :
a. Racemose : 


  • Growth of peduncle is infinite or unlimited. 
  • Apical bud is free for continuous growth. 
  • Flowers are borne in acropetal succession. (Mature flowers at the base) Order of opening is centripetal.




b. Cymose :


  • Growth of peduncle is finite limited. 
  • Apical meristem terminates into flower.
  • Flowers are borne in basipetal succession. (Mature flowers at the apex) Order of opening is centrifugal.

  9. Morphology of Flowering Plants - part 02 - STEM Stem :  The aerial part of the plant body is know as  shoot system.  Stem is the main axis of this shoot system.  Stem is the ascending part of the plant body which develops from  plumule  and reproductive units and is differentiated into  nodes and internodes.  It is usually  positively photorophic, negatively geotropic and negatively hydrotropic.  It shows different types of buds ( axillary, apical, accessory , etc.). At nodes it produces dissimilar organs such as leaves and flowers and similar organs such as branches.  Young stem is green and capable of photosynthesis. The primary functions of the stem are - To produce and support branches, leaves, flowers and fruits;  conduction of water and minerals and  transportation of food to plant parts. Modifications of stem :  Stem develops some modifications for additional or accessory functions. To perform such function stem shows different modifications : a. Underground stem :  In some

01 Reproduction in Lower and Higher Plants - part 05 - pollination Pollination :  Pollen grains being non motile, angiosperms have evolved the strategy to use - Abiotic agents (wind, water) and biotic agents (birds, insects, snails) to their flowers,  Feeding the visitors and  Exploiting their mobility for pollination and also seed dispersal.  Pollen grains are non-motile and they are usually carried from flower to flower by means of external agents.  Pollination is the  transfer of pollen grains from anther to the stigma  of the flower.  It is the prerequisite for fertilization because both the male and female gametes are non-motile.  Moreover gametes are produced at two different sites. Self pollination : It is a type of pollination which occurs  in a single flower or two flowers on a single plant.  It results in inbreeding or selfing.  In contrast cross pollination is the transfer of pollen grains from the anther of one flower to the stigma of another flower of different plants of
