Final answer:
Chloroplasts are the organelles responsible for capturing sunlight energy and performing photosynthesis in certain organisms, allowing them to convert solar energy into chemical energy. Animal cells and fungal cells do not have chloroplasts and rely on other organisms for their energy.
Step-by-step explanation:
Chloroplasts are the organelles responsible for capturing sunlight energy and performing photosynthesis in certain organisms. These organelles are found in plant cells and algal cells and allow them to convert solar energy into chemical energy in the form of carbohydrates. Chloroplasts contain the pigment chlorophyll, which absorbs light energy and converts it into chemical energy through a series of chemical reactions. Other organisms, such as animal cells and fungal cells, do not have chloroplasts and rely on other organisms for their energy.
