Which of the following protists are autotrophic. Select all that apply. Partial credit will be given.

Question

Question 8 options:

Paramecium

brown algae

radiolarian

red algae

slime mold

green algae

Answer 1

The autotrophic protists from your list are:

1. Brown algae - These are multicellular and contain chlorophyll, allowing them to photosynthesize.
2. Red algae - They are also photosynthetic and contain pigments that allow them to capture light energy.
3. Green algae - This group is primarily autotrophic and includes many freshwater and marine species that perform photosynthesis.

The other options—Paramecium (which is heterotrophic), radiolarian (which are also mostly heterotrophic), and slime mold (which is heterotrophic as well)—are not autotrophic.

So, the correct answers are:

• Brown algae
• Red algae
• Green algae
