NEET BIOLOGY

Detailed explanation-1: -Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar).

Detailed explanation-2: -Photosynthesis is the process by which light energy is converted to chemical energy whereby carbon dioxide and water are converted into organic molecules. The process occurs in almost all algae, and in fact much of what is known about photosynthesis was first discovered by studying the green alga Chlorella.

Detailed explanation-3: -Algae (singular alga) are a diverse group of plant-like aquatic organisms. Oceanic algae is often referred to as phytoplankton. These simple organisms use photosynthesis to produce energy from sunlight, which allows them to make carbohydrates, oils and proteins.

Detailed explanation-4: -Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
