Reproduction in Organisms Test - 13

Sucker is underground shoot that some stage emerges above the soil surface and gives rise to a new plant. It is initially nourished by parent plant but later become independent.

Fruit formation without fertilisation results into seedless fruit. Parthenogenesis is development of new individual from unfertilised eggs. Parthenocarpy can be induced artificially using plant hormone auxin.

Bryophyllum plants grow in marshy areas where seeds are not able to germinate. The leaf margin of Bryophyllum contains numerous plantlets before falling on muddy land.

During vegetative propagation, new organisms are formed by single plant parts. So, new individuals are genetically similar to each other and there is no genetic variation.

Gemmules are internal buds found in sponges and are involved in asexual reproduction. It is an asexually reproduced mass of cells, that is capable of developing into a new organism i.e., an adult sponge

In Hydra small outgrowth develops at the bottom side which grows into a bud. The well-developed buds detach from the parent body as new individual.

Corm is an organ of perenation and vegetative propagation consisting of a short erect fleshy swollen underground stem. It store food material.

Micropropagation is the technique of growing large number of plantlets using small parts of plants. Plant parts are totipotent or able to generate whole plant with small portion. This process is also called as tissue culture in which true type of plants.
