Mammals push just like humans do. Birds do poop while flying, although they often poop just before taking off, perhaps to lighten their load. Although this might not reassure your seven-year-old, you might also mention that in some cultures people believe that is very good luck to be hit by bird poop. Fish poop through the end like us and reptiles have anuses.

Significance of osmosis in unicellular organisms and plants?
Osmosis is important because some unicellular organisms are rather small and do not require intricate systems therefore it allows plants to easily take water from the soil by way of the roots making it simple and effective.
What life functions are carried out by unicellular organisms?
Well you see unicellular organisms are very unique in the fact that they live all on their own and move around with a flagellum or little motor, but to the point unicellular organisms carry out esscentally every function in life and they must in order to simply survive. One function is reproduction and they reproduce asexually
How does gas exchange take place?
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have:a large surface areaa thin permeable surfacea moist exchange surface.
Compare cells of plants animals and unicellular organisms?
Plant Cells: Cell Wall, Cell membrane, nucleus, ribosomes, endoplasmic reticulum, Golgi bodies, cytoplasm. Animal cells : Cell membrane, nucleus, ribosomes, endoplasmic reticulum, Golgi bodies, cytoplasm Unicellular: Depends on what kind of unicellular organism.
What are some advantages of being unicellular?
If you are unicellular you will be able to reproduce very quickly, thereby making more of your type of cells quickly. Another advantage to being unicellular is that unicellular organisms live a short life, so they are able to adapt very quickly, verses a multi-cellular organism that could take hundreds of years to adapt.
How does excretion take place in Mammals bodies?
Excretion is the elimination of waste from the body.
How long did it take for unicellular organisms to evolve to multicellular?
Answer is not exactly known, as origin of first unicellular organisms is unknown. First multicellular organisms appeared in late Precambrian. Look up Burgess Shale for details.
What is the excretion of cnidaria?
it is where the the nutrients runs out of the mouth or the anus of the organism therefor they take the nutrients that other organisms leave behind and they get the nutrients from that that is the excretion of cnidaria
How excretion take place in protozoa?
excreation takes place by contractile vacoule
What do unicellular drink?
The process of drinking by unicellular organisms is called pinocytosis. Cells take in drops of liquid outside the cell. They take in meager drops of extra-cellular fluids.
Why are multicellular organisms more efficent than unicellular organisms?
Multicellular organisms work like an assembly line, and if one part of a multicellular organism dies, it can be replaced, but if a part of a unicellular organism dies, the entire organism dies. The assembly line process is called specialization.

What organisms take place in photosynthesis?
plants and protists

What organisms do photosynthesis and cellular respiration occur to?
Respiration take place in all.Photosynthesis take place in auto phototrophs
