Final answer:
Plants and algae are two eukaryotic groups that have cellulose cell walls and chloroplasts.
Step-by-step explanation:
In the domain Eukaryota, plants and algae are two eukaryotic groups that have cellulose cell walls and chloroplasts. Cellulose is a complex carbohydrate that provides structural support to the cell wall, while chloroplasts are responsible for photosynthesis, the process of converting sunlight into glucose for energy.
Plants are multicellular organisms that have chlorophyll a and b as photosynthetic pigments. They have cellulose cell walls and are capable of producing their own food through photosynthesis. Algae, on the other hand, can be either unicellular or multicellular and also have chloroplasts and cell walls made of cellulose, but they are not considered plants.
To summarize, plants and algae are two eukaryotic groups that have cellulose cell walls and chloroplasts, which enable them to carry out photosynthesis.
