GENERAL HISTOLOGY

Detailed explanation-1: -In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Detailed explanation-2: -The organelles that contain a green pigment and are selectively found in plants are called chloroplasts. These organelles contain chlorophyll pigment, which allows them to capture solar energy to prepare food.

Detailed explanation-3: -What makes a leaf green is chlorophyll, the green pigment located within the chloroplasts. More specifically, chlorophyll resides in the thylakoid membranes. The chlorophyll absorbs energy from sunlight, and it is this energy that drives the synthesis of food molecules in the chloroplast.

Detailed explanation-4: -Chloroplastida (green algae and plants) Green algal chloroplasts are characterized by their pigments chlorophyll a and chlorophyll b which give them their green color.

Detailed explanation-5: -As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.
