The sun is the ultimate source of energy for virtually all organisms. Photosynthetic cells are able to use solar energy to synthesize energy-rich food molecules and to produce oxygen.

Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...

Cell structure Description Function Cell type ... plant cell or fungal cell Chloroplasts Disc-shaped structures found in cytoplasm Location where photosynthesis occurs and sugar is produced?

The team isolated the chloroplasts from algal cells using a centrifuge and gentle stirring. Instead of then piercing the host cells’ membranes, as in earlier work, the researchers adjusted the culture ...

The precise structure sheds fresh light on the ... such as in bacteria or the cell nucleus of higher cells. However, it ...
