Answer:

Start the reaction by absorbing light energy

Explanation:

Photosynthetic pigments are substances present in the chloroplasts of autotrophic beings. They have the function of absorbing light, triggering the photochemical reactions of photosynthesis, a fundamental process for the maintenance of life on the planet. With this, we can say that the role of pigments in the photosynthesis reaction is to initiate the reaction by absorbing light energy.

The different pigments (chlorophylls and carotenoids) absorb different wavelengths of sunlight, which is the main energy source on the planet.

Answer:

Option A, Start the reaction by absorbing light energy

Explanation:

Chlorophyll is a green color pigment in plant that helps in entrapping sunlight. Being green in color, it absorbs the blue and red light and reflects the green light. The molecules of chlorophyll gains energy from sunlight and then jumps to higher energy levels by the process known as photo excitation. These excited molecules get ionized to further initiate the process of photosynthesis.

Hence, option A is correct.

1. Enzyme is the molecule that serves to make reactions work. Enzymes are biochemical catalysts that catalyses chemical reactions in a cell by acting on substrates and convert them to products. Their rate of action increases with increase in substrate concentration, reaching optimum when all active sites of the enzyme are engaged.

2. Plastid are the tiny sacs in the cell that may contain starch. Plastid are major cell organelles found in the cells of plants and algae. Plastids are site for the manufacture and storage of important  chemical compounds used by the cell. They often contain pigments used in photosynthesis, and the types of pigments present can change or determine cells color.

3. Lysosome are packets within the cell that contain digestive enzymes. Lysosomes are one of many organelles found in animal cells. they are tiny like sacs filled with enzymes that enables the cell to process nutrients. They contain digestive enzymes which helps in the digestion of worn out organelles, food particles and engulfed viruses or bacteria.

4. Mitochondrion is a structure within a cell that is responsible for production of energy. Energy in a cell is produced through a process of cellular respiration which involves use of nutrients with oxygen gas to yield energy inform of ATP, water and carbon dioxide. The process takes place in the mitochondrion where oxygen acts as proton acceptor in the electron transport chain coupled by production of energy.

5. An Organelle is a small structure that serves specialized functions. A cell is made up of various organelles that help it perform its functions. Each organelle is specialized to perform as specific function different from other organelles, for example ribosomes is an organelle involved in the manufacture of proteins.

6. Golgi apparatus are group of flattened sacs that package and export materials out of the cell. Golgi apparatus also called golgi complex or golgi body, is a membrane bound organelle in eukaryotic cells that is made up by a series of flattened, stacked pouches called cisternae. They are responsible for transporting, modifying, and packaging proteins and lipids into vesicles.

7. Vesicles are tiny sacs connected to the Endoplasmic reticulum and Golgi apparatus. Vesicles are small structures within a cell, or extracellular, consisting of fluid enclosed by a lipid bi-layer. they form naturally during the process of secretion (exocytosis), uptake (endocytosis) and transport of materials within the cytoplasm.
