Question

which protist exhibits both animal - like and plant - like characteristics?
○ a protist that has pseudopods and swims by using cilia
○ a protist that makes its own food and has glass - like cell walls
○ a protist that is a heterotroph and has chlorophyll
○ a protist that can move or be stationary

Explanation:

• Option 1: A protist with pseudopods and cilia - Pseudopods are for movement (animal - like in some ways, but cilia are also a form of locomotion. However, there is no plant - like characteristic (e.g., photosynthesis) mentioned here.
• Option 2: A protist that makes its own food (plant - like, autotrophic) and has glass - like cell walls (diatoms have silica - based cell walls). But there is no clear animal - like characteristic (e.g., heterotrophic feeding in some situations) emphasized.
• Option 3: A heterotroph (animal - like, as animals are heterotrophs) and has chlorophyll (plant - like, as plants use chlorophyll for photosynthesis). This shows both animal - like and plant - like characteristics.
• Option 4: A protist that can move or be stationary. Movement is more of an animal - like characteristic (but some plants can have limited movement - like tendrils moving towards light), and stationarity is more plant - like. But it is a very general characteristic and not as specific as the combination in Option 3.

Answer:

a protist that is a heterotroph and has chlorophyll
