What is the role of ATP in our bodies? What is the role of chlorophyll during photosynthesis? What is the role of light during the process of photosynthesis? What is ATP synthase and what is its role? What are the metabolic roles of ATP, NAD+, and NADPH in photosynthesis and cellular ...
Q2: What is the role of chlorophyll in photosynthesis? Ans: Chlorophyll is a pigment molecule that absorbs light energy from the sun and transfers it to other molecules within the plant cell. It is the primary pigment involved in photosynthesis and gives plants their green color. Chlorophyll is...
Photosynthesis occurs in chloroplasts, a type of plastid (an organelle with a membrane) that contains chlorophyll and is primarily found in plant leaves. Chloroplasts are similar tomitochondria, the energy powerhouses of cells, in that they have their own genome, or collection of genes, contained...
Chromoplasts are pigmented plastids. They impart a variety of colours to plant cells. They contain carotenoids but lack chlorophyll.
Porphyrinsare cyclic tetrapyrroles that perform critical roles in a variety of biological systems. ... Several types of chlorophylls exist which differ with respect to the substituents on the tetrapyrrole ring. Chlorophylls are employed by photosynthetic organisms to absorb energy for photosynthesis. ...
Water plays a multifaceted role in plant biology, not only as a solvent for nutrient uptake but also as a key player in photosynthesis and transpiration. It’s essential for the movement of nutrients through the xylem, and for maintaining cell turgidity, which keeps plants upright and robust....
