Reproduction In Organisms Flashcards
(22 cards)
Simple binary fission is seen in
Amoeba
Transverse binary fission is seen in
Paramecium and planaria
Longitudinal binary fission is seen in
Euglena and vorticella
Multiple fission occurs during and in
And layers
During unfavourable conditions
3 layer encystation occurs
In amoeba, monocysts, plasmodium
Budding is seen in
Gemmules (internal buds) are seen in
Hydra
Gemmules- spongilla and sycon
Regeneration is seen in
Planaria
Spore is seen in
Chlaydomonas
Special asexual reproducing structure in fungi and algae
Zoospores
Conidia of penecillium
Rami->metula->philides(sterigmata)-> conidia
Why do fungi and algae switch to sexual mode of reproduction
During adverse conditions they switch to sexual mode of reproduction to bring variations among the individuals
Potato in vegetative propagation is
Underground root - tuber
Ginger,turmeric,banana in vegetative propagation are
Underground root- rizome
Onion and garlic in vegetative propagation are
Underground root- bulb
Amorphophallus, colocasia and crocus in vegetative propagation are
Underground root- corm
Grass is
Creeping stem - runner
Water hyacinth/terror of bengal is
Creeping stem- offset

Banana, pineapple, crysanthemum
Examples of stolon (branching in all directions from lowest node)
Strawberry, vallisneria
Examples of vegetative propagation by root are
Dallergia sisso (sesam) and sweet potato
Examples of vegetative propagation by leaf
Bryophillum and adiantum(walking fern)
Examples of vegetative propagation by bulbis
Agave, oxalis and lily
Example of Turions (fleshy bud in aquatic plants which help in pernnation)
Utricularia
