Detailed explanation-1: -Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green.

Detailed explanation-2: -The green color of chlorophyll is secondary to its importance in nature as one of the most fundamentally useful chelates. It channels the energy of sunlight into chemical energy, converting it through the process of photosynthesis.

Detailed explanation-3: -Chlorophyll b is a form of chlorophyll. Chlorophyll b helps in photosynthesis by absorbing light energy. It is more soluble than chlorophyll a in polar solvents because of its carbonyl group. Its color is green, and it primarily absorbs blue light.

Detailed explanation-4: -Why are chloroplasts green? Chloroplasts are green because they contain the pigment chlorophyll, which is vital for photosynthesis. Chlorophyll occurs in several distinct forms. Chlorophylls a and b are the major pigments found in higher plants and green algae.

Detailed explanation-5: -Chlorophyll or leaf green is a porphyrin derivative with magnesium as the central atom and is hence a metal complex dye. It is present in the chloroplasts in all green parts of plants as a mixture of blue green chlorophyll a and yellow green chlorophyll b, and constitutes the catalyst for photosynthesis.
