how do amoebeas react to danger, heat and cold and how do they drink i need full explanations?

Question

plz no dumb answers...and im in gr 9...so no complicated thing...thank you...

Answer 1

Amoebae react to danger usually by moving out of the way. If something is to hot or cold, they will...move away from it, if they can't and it's too hot or cold they'll die. They don't really "drink" but they absorb water through their membrane...they usually live in water, so that's not a problem.

Have you ever seen them eat?...It's pretty interesting...they engulf bacteria...and a few million years back, something like that kicked off endosymbiosis...which is something I will not scare you with right now. ;)

Amoeba itself is found in freshwater, typically on decaying vegetation from streams, but is not especially common in nature. However, because of the ease with which they may be obtained and kept in the lab, they are common objects of study, both as representative protozoa and to demonstrate cell structure and function. .. Each has a single nucleus, and a simple contractile vacuole which maintains its osmotic pressure, as its most recognizable features. It obtains its food by phagocytosis.

A good method of collecting amoeba is to lower a jar upside down until it is just above the sediment surface. Then one should slowly let the air escape so the top layer will be sucked into the jar. Deeper sediment should not be allowed to get sucked in. It is possible to slowly move the jar when tilting it to collect from a larger area. If no amoeba are found, one can try introducing some rice grains into the jar and waiting for them to start to rot. The bacteria eating the rice will be eaten by the amoeba, thus increasing the population and making them easier to find.


sorry but hope this will help!!!

Answer 3

Amoebas are ancient protozoans. They are said to be called as living fossils.

They simply move away from the site. There's also a way in which they undego a stage called Encapsulation where they protect or defend themselves from any kind of Advorse conditions.

Amoebae just engulf the food particles with a process called Holozoic mode of Nutrition.

I think this answer works out for you.
