Final answer:
The membrane studded with photosynthetic pigments in plant cells is the chloroplast.
Step-by-step explanation:
The membrane studded with photosynthetic pigments in plant cells is the chloroplast. This organelle is responsible for the process of photosynthesis, which takes place in the chlorophyll-rich thylakoid membranes within the chloroplast. The thylakoid membranes contain the pigment chlorophyll, which captures sunlight and converts it into chemical energy.
