GENERAL HISTOLOGY

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: -A pigment within the chloroplasts of a plant cell is responsible for the green color. It makes a lot of sense that many plants are green because their cells are green, but what gives them this color? The answer is a substance called chlorophyll.

Detailed explanation-4: -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-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.
