6. what kinds of organisms carry out photosynthesis? a. plants, algae, and fungi b. bacteria, algae, and fungi c. plants, algae, and bacteria d. bacteria, fungi, and plants

C, Plants, algae, and bacteria

Plants and algae both consists chloroplast and carry out photosynthesis to make their own food. A group of bacteria(not all bacteria) is able to carry out photosysthesis like plants and algae to make their own food. These group of bacteria contain light absorbing pigment that makes them able to photosynthesize. Some common bacteria that  photosynthesize are cynobacteria, purple bacteria, green sulphur bacteria and green gliding bacteria. These all bacteria contain pigment to absorb light and perform photosynthesis to make their own food.

Photosynthesis carries out by plants, algae, and bacteria.

Further Explanation:

Photosynthesis starts with the absorption of light or solar energy by the plant pigments called chlorophyll. The activated chlorophyll molecule helps in the electron transfer from one acceptor to another forming a chain.

Mainly photosynthesis occurs in bacteria, algae and plants. The plant and algae both consists chloroplast that carry out photosynthesis through this process they can make their own food. Some bacteria can perform or carry photosynthesis and make their own food. Bacteria consists pigment which can easily absorb by light and carry out photosynthesis. Some examples of autotrophic bacteria are purple bacteria, cyanobacteria and green sulphur bacteria.

The first phase of photosynthesis the light-dependent reaction in which the absorbed light is utilized to produce molecules carrying energy that is used in the second phase to form carbohydrates by reducing carbon dioxide. The second phase of the photosynthesis is the dark reaction or the light-independent reaction happens in the stroma and utilizes the products formed during the light-dependent phase.
