A type of plastid that contains chlorophyll which is where photosynthesis takes place.
An organelle that modifies,sorts,and packs molecules and stores or sends it around the cell when needed.
Often known as the "powerhouses" of the cell, this organelle generates energy for the cell through cellular respiration.​ This means it takes in nutrients from the cell, breaks it down, and turns it into energy. /
