What organelle holds chlorophyll?

The organelle that holds chlorophyll is called the chloroplast.

To understand how to get the answer to this question, let's break it down into steps:
1. Identify the topic: The question is asking about an organelle that holds chlorophyll.
2. Gather relevant knowledge: Chlorophyll is a pigment that plays a key role in photosynthesis, the process by which plants and some other organisms convert sunlight into chemical energy.
3. Recall cell biology: In cell biology, organelles are specialized structures within cells that have specific functions. One of the organelles associated with photosynthesis is the chloroplast.
4. Connect chlorophyll to an organelle: Remember that chlorophyll is responsible for the green color of plants and is necessary for photosynthesis. Since photosynthesis occurs in plant cells (and some other organisms, like algae), it is reasonable to conclude that chlorophyll is located within an organelle in plant cells.
5. Recall the function of the chloroplast: The chloroplast is the organelle where photosynthesis takes place. It contains chlorophyll and other pigments that capture light energy and convert it into chemical energy.
6. Formulate the answer: Putting all the information together, the organelle that holds chlorophyll is the chloroplast.

So, the answer to the question "What organelle holds chlorophyll?" is the chloroplast.
