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.
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.
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
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.
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.
Metabolism is the set of all chemical process that take place in the body. The processes allow all life sustaining functions needed in the cells of living organisms.
Excretion is the elimination of waste from the body.
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
excreation takes place by contractile vacoule
It is believed to have taken about 2 billion years for unicellular organisms to evolve into multicellular organisms. The transition from unicellular to multicellular life forms is thought to have occurred around 600 million years ago.
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.
The life processes of unicellular organisms take place within a single cell. This includes functions such as metabolism, reproduction, and response to stimuli, all occurring in the cell's cytoplasm and organelles. Since these organisms are composed of just one cell, they must perform all necessary life functions independently. Examples include bacteria and protozoa, which carry out processes like nutrient absorption and waste elimination within their cellular structure.

Division of labor is not present in unicellular organisms because these organisms consist of a single cell that performs all necessary functions for survival, such as metabolism, reproduction, and response to stimuli. Unlike multicellular organisms, where specialized cells can take on distinct roles, unicellular organisms rely on the same cellular machinery to carry out all life processes. This simplicity allows them to efficiently manage their activities within a single cell, making division of labor unnecessary.

Respiration take place in all.Photosynthesis take place in auto phototrophs
