Final answer:
The types of living things are able to do photosynthesis is 1) Plants only
Step-by-step explanation:
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis. These organisms are known as photoautotrophs because they use light to manufacture their own food. They convert light energy from the sun into chemical energy in the form of carbohydrates.
Plants are the most well-known photoautotrophs and are often the first organisms that come to mind when thinking about photosynthesis. They have specialized cells called chloroplasts that contain a green pigment called chlorophyll, which captures sunlight and enables photosynthesis to occur. Plants serve as the primary producers in many ecosystems, providing food and oxygen for other organisms.
In conclusion, the correct answer is 1) Plants only. Only plants, algae, and cyanobacteria are capable of performing photosynthesis as they have the necessary structures and pigments to capture light and convert it into chemical energy.
