Answer:
b. chloroplast
Explanation:
Chloroplasts are the double membrane-bound organelles that serve as the site for photosynthesis in eukaryotes. Chloroplasts are the organelles where eukaryotic autotrophs synthesize the organic nutrients by the process of photosynthesis. According to the given information, the first eukaryotic cells were heterotrophs as they derived energy by available organic compounds. They did not synthesize the organic nutrients to use them as fuel. Chloroplasts are not present in heterotrophic organisms such as animals. Therefore, chloroplasts are most likely to have appeared last in the eukaryotic cells.
The answer is glucose and oxygen.
Answer:
Cell wall and plastid
Explanation:
The most important difference between plant cell and animal cell is that plant cell contain cell wall for mechanical strength and plastid to carry out photosynthesis(chloroplast). and storage(leuko plast).
But in case of animal cell cyto skeleton is present in place of cell wall and plastid is absent because animals generally does not carry out photosynthesis.
