Answer:
e) unicellular, colonial, or multicellular.
Explanation:
Protists originates from the Kingdom Protoctista. They comprise of organisms that are unicellular (Amoeba) or unicellular-colonial (volvox) in nature and which have no tisssues, therefore they are at the cellular level of organization.
Examples include, Amoeba, Paramecium, Euglena, Slime mold, Kelp, Diatoms, DInoflagellates. etc.
Some of them are also considered to be multicellular eukaryotes e.g slime molds, red algae etc. Eukaryotic organisms are organisms that possess cells containing a nucleus.
Characteristics in which protists exhibit varies from one species to the other.
For example, the mode of nutrition in eukaryotic algae are autotrophic in nature, in amoeba, they are gifted with pseudopods(false feets) in which they used to engulf prey(a term known as phagocytosis) therefore making them to be heterotrophic in nature.
In protist, locomotion varies from one organism to another. For example, in Amoeba , locomotion is achieved by extending and retracting pseudopods, Euglena are flagellated in nature , hence they move with the flagella. In Paramecium that are ciliated in nature, they move by propelling their cilia. etc.
<u>Answer:</u>
ATP or the Adenosine Triphosphate is the energy currency of the living world, which transfers energy from one organic molecule to other, even from one cell organelle to other.
<u>Explanation:</u>
The functional group of ATP is phosphate which is quite evident from its name.
Adenosine diphosphate is the parent molecule. During either photophosphorylation or the respiration, the Inorganic phosphate molecule that is present in the cellular fluid gets attached to the parent molecule ADP via a high energy bond which is broken to give energy to the normal reactions.
