Detailed explanation-1: -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-2: -Chloroplasts house a pigment called chlorophyll, which is responsible for absorbing energy from sunlight to carry out photosynthesis. Chlorophyll absorbs only blue and red wavelengths for photosynthesis. It does not absorb green wavelengths. Instead, it reflects green light, causing the chloroplast to appear green.

Detailed explanation-3: -These accessory pigments can be other chlorophylls or they can be completely different pigments with completely different colors, including yellow (xanthophylls), orange (carotenes), red and purple (phycobilins) or brown and gray (phaeophytin).

Detailed explanation-4: -A chloroplast is a structure in a plant cell that contains chlorophyll. Chlorophyll is a pigment that gives plants their green color.
