Chloroplasts within the Euglena trap sunlight that is used for photosynthesis, and can be seen as several rod-like structures throughout the cell.
Functions of the leaf. Chloroplasts chloroplast: Microscopic structure containing chlorophyl found in green plant cells where photosynthesis takes place. are the tiny structures in plant cells where photosynthesis happens.Chloroplasts contain chlorophyll chlorophyll: The green chemical inside the chloroplasts of plant cells.It enables photosynthesis to take place. , a green pigment that absorbs light energy for photosynthesis. However, chloroplasts are not found in all plant cells.hloroplasts chloroplast: Microscopic structure containing chlorophyl found in green plant cells where photosynthesis takes place. are the tiny structures in plant cells where photosynthesis happens.
