Protist
A)using another for one's own benefit; having to do with an organism that draws benefit from another
B)a single-celled organism that has characteristics of both plants and animals
C)another term for a moneran; a single-celled algae
D)a part of a cell which has a particular function
E)the process by which sunlight is turned into sugars within a plant
B) a single-celled organism that has characteristics of both plants and animals.
Legume
A)a small swelling on the root of a legume
B)a type of plant that fixes nitrogen into soil
C)to replace what was lost
D)a chemical that is formed by nitrogen and another element
E)wa complex chemical in the body of an organism that has a particular purpose
B) a type of plant that fixes nitrogen into soil.
The correct answer is B) a single-celled organism that has characteristics of both plants and animals.
To arrive at this answer, let's break down the choices and eliminate the options that do not match the definition of a protist:
A) Using another for one's own benefit; having to do with an organism that draws benefit from another - This definition describes a parasitic relationship, which is not specific to protists.
C) Another term for a moneran; a single-celled algae - This choice is incorrect because monerans refer to a different category of organisms, and algae are not synonymous with protists.
D) A part of a cell which has a particular function - This definition describes an organelle, which is not specific to protists.
E) The process by which sunlight is turned into sugars within a plant - This definition describes photosynthesis, which is a process that occurs in plants, but not an exclusive characteristic of protists.
By process of elimination, the correct answer is B) a single-celled organism that has characteristics of both plants and animals. Protists are a diverse group of eukaryotic microorganisms that can exhibit characteristics found in both plants and animals, such as the ability to photosynthesize like plants and also move like animals.
