Detailed explanation-1: -Chloroplasts contain the pigment chlorophyll to absorb light energy. In plants, these essential organelles occur in all green tissues, though they are concentrated particularly in the parenchyma cells of leaves.

Detailed explanation-2: -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-3: -Most plant cells are green due to the presence of chlorophyll, the pigment that traps sunlight, which the plant then uses as part of photosynthesis.  But you can’t always count on this to be true. Flower cells may contain red, orange and yellow pigments, and root cells may contain no colorful pigments at all.

Detailed explanation-4: -Chloroplasts are also found in photosynthetic tissues that do not appear green, such as the brown blades of giant kelp or the red leaves of certain plants. In plants, chloroplasts are concentrated particularly in the parenchyma cells of the leaf mesophyll (the internal cell layers of a leaf).

Detailed explanation-5: -Plant cells are eukaryotic cells that vary in several fundamental factors from other eukaryotic organisms. Both plant and animal cells contain a nucleus along with similar organelles. One of the distinctive aspects of a plant cell is the presence of a cell wall outside the cell membrane.
