Question

Paramecium ke bare me 10 main points

Answer 1

Paramecium move with the help of the cilia which are hair-like structures that create whiplash like movements. This movement is similar to oars moving a boat along.Paramecia consume yeasts, algae, and bacteria as food. In order to eat they use their cilia to sweep their prey into their oral groove and then into the mouth.Some paramecia are able to form relationships with other organisms that provide mutual benefit.Paramecia reproduce through binary fission with means the macronucleus splits, creating micronuclei which then undergo mitosis. This is referred to as asexual reproduction. The offspring from this type of reproduction is identical to the original paramecium.Paramecia can also reproduce sexually when they are experiencing starvation. Only paramecia of the same species can mate, and only different mating types can mate. The offspring from this type of reproduction is genetically new.Paramecia are from the protozoa class.Paramecia have no eyes, no heart, no brain, and no ears.Paramecia are able to undergo reproduction and digestion even without many of the systems in other organisms.When a paramecium ingests food it also ingests water, which is pumped out via the vacuole pumps.Paramecia have a stiff outer cover that gives it its slipper like appearance.




Mark it as brainliest please...(￣ω￣;)

Answer 2

I. it is found in freshwater ponds, pools, ditches, lakes, etc. it is abundantly found in stagnant water, where decaying organic matter is in plenty.
ii. it moves here and there with the help of cilia .
iii. cilia help in food capture.
iv. it ingests bacteria and other microscopic organism or minute protozoans. so nutrition is holozoic.
v. digestion : intracellular
vi. respiration takes place by general body surface through diffusion process.
vii. excretion is done contractile vacoule and cytoproct.
viii. reproduction : asexually by transverse binary fission and sexually by conjugation.
ix. paramecium is a unicellular, microscopic, free living organisms.
x. paramecium was named by john hill in 1752. and Antony van leeuwenhoek described about paramecium.
