Plastids are vital organelles in plant cells. Which of the following is a function of plastids?

Correct option is C

The correct answer is (C) Photosynthesis.

Explanation:
Plastids are specialized organelles found in plant cells, and their primary function is to carry out photosynthesis, the process by which plants convert light energy into chemical energy in the form of glucose. The most important type of plastid involved in this process is the chloroplast, which contains the green pigment chlorophyll that absorbs light energy.

Information Booster:

• Plastids are membrane-bound organelles found in plant cells and some algae. They are involved in several key functions, including photosynthesis, storage of nutrients, and pigment synthesis.

• The most well-known plastids are chloroplasts, which are responsible for photosynthesis and contain chlorophyll, the green pigment that absorbs sunlight.

• Other types of plastids include chromoplasts (responsible for the synthesis of pigments like carotenoids, giving fruits and flowers their color) and leucoplasts (which are involved in the storage of starch, lipids, and proteins).

• Photosynthesis in chloroplasts is vital for converting sunlight into usable energy for the plant, which is then passed through the food chain.

Additional Knowledge:

• Movement of organelles: This is typically facilitated by the cytoskeleton, which is made up of proteins such as microtubules and actin filaments.

• Synthesis of proteins: The ribosomes are responsible for protein synthesis in cells, not plastids.

• Storage of genetic information: This function is carried out by the nucleus in eukaryotic cells, where DNA is stored and transcribed.
