Eugen Bleuler. (Swiss psychatrist)
Most animals are well adapted to their biotic and abiotic conditions due to behavioural, physiological or structural adaptations that increase their chances of survival and reproduction. I looked it up for you
Algae are photosynthetic, but they are also unicellular organisms (Euglena) and shares some of the common features with plants as well as animals. They move like animals and perform photosynthesis like plants. Therefore, they are classified into Protists, and not the Algae. Their most features resemble the non-photosynthetic protozoa, and not plants, and therefore, are put into the Protista.
They also lack a cell wall, which is a feature of plants.
Some scientists advocate their classification in plants because of their sexual mode of reproductiona, and formation of spores.
it really does depend on what type of 'cell' your talking about. If your talking about a battery type of cells then it's obviouse but I know that there are 3 trillion cells in your body :) reply if this was helpfull
