A gelatinous matrix inside the chloroplast containing ribosomes, DNA and enzymes is the:

• A. Granum
• B. Chlorophyll.
• C. Thylakoid.
• D. Stroma.
• E. Mitochondria.

Answer: (D)

Verified step by step guidance

1. Begin by identifying the structure of a chloroplast. Chloroplasts are organelles found in plant cells and are responsible for photosynthesis.
2. Understand the components within a chloroplast. The chloroplast contains several key structures: thylakoids, grana, stroma, and chlorophyll.
3. Define each component: Thylakoids are membrane-bound compartments inside chloroplasts, grana are stacks of thylakoids, chlorophyll is the pigment responsible for capturing light energy, and the stroma is the fluid-filled space surrounding the thylakoids.
4. Recognize the function of the stroma. The stroma is a gelatinous matrix that contains ribosomes, DNA, and enzymes necessary for the synthesis of organic molecules during photosynthesis.
5. Conclude that the stroma is the correct answer, as it matches the description of containing ribosomes, DNA, and enzymes within the chloroplast.
