Answer: Option D. Vestigial trait
Explanation:
Vestigial traits simply involves those traits (such as organs, structurrs or behaviors) which are found or occurs in organisms or animals, that have lost all or most of their original function through evolution. These vestigial structures were organs that performed some important functions in the organism at one point in the past. In most cases, organs or traits once identified as vestigial simply had an unrecognized function.
Photosynthesis in algae cells
Ecosystems were able to maintain themselves by cycling the
nutrients and energy obtained from external sources. The flow of energy through
a food chain is known as energy flow. At tropical level, solar energy is used by the primary producers to produce organic plants materials through photosynthesis.
I have the same question right now and the correct answer is photosynthesis
Answer:
No, eukaryotic cells cannot live without mitochondria and chloroplasts; they provide the energy cells need to survive.
Explanation:
It is not possible today for a eukaryotic cell to live without mitochondria or chloroplasts since these are the organelles responsible for providing the energy cells need to survive.
Mitochondria are the organelles that synthesize energy in cells. Chloroplasts are the organelles that contain chlorophyll and where photosynthesis takes place in a cell.
