You are given the task of designing an aerobic, mixotrophic protist that can perform photosynthesis in fairly deep water (for example, 250 meters deep) and can also crawl about and engulf small particles. With which two of the following structures would you provide your protist?1. hydrogenosome
2. apicoplast
3. pseudopods
4. chloroplast from red alga
5. chloroplast from green alga

3. pseudopods

4. chloroplast from red alga

Explanation: Pseudopods are extensions of the Cytoplasm of cells like Amoeba, they are changed in shape and appearance in order to aid the movement and for predation of the organisms that possess it.

Chloroplast from Red algae are characterized as not having Centrioles and flagella in their Eukaryotic cells and are known to contain the red pigments instead of the green pigments as seen generally in chloroplast.

b is the correct answer
