Verified step by step guidance

Understand the structure of a chloroplast: Chloroplasts are organelles found in plant cells and are responsible for photosynthesis. They have several components, including the stroma, thylakoids, and grana.

Identify the function of each component: The stroma is the fluid-filled space surrounding the thylakoids in chloroplasts. It contains enzymes, ribosomes, and chloroplast DNA, which are essential for the synthesis of organic molecules.

Differentiate between the options: Granum is a stack of thylakoids, chlorophyll is a pigment, thylakoids are membrane-bound compartments, and mitochondria are organelles involved in energy production, not part of the chloroplast.

Focus on the description given: The problem describes a 'gelatinous matrix inside the chloroplast containing ribosomes, DNA, and enzymes.' This description matches the stroma, which is known for containing these components.

Conclude based on the information: Given the description and the functions of each component, the correct answer is 'd) Stroma,' as it fits the description of containing ribosomes, DNA, and enzymes within the chloroplast.
