Chloroplasts are observable as flat discs usually 2 to 10 micrometers in diameter and 1 micrometer thick. In land plants, they are, in general, 5 μm in diameter and 2.3 μm thick. The chloroplast is contained by an envelope that consists of an inner and an outer phospholipid membrane. Between these two layers is the intermembrane space. A typical parenchymacell contains about 10 to 100 chloroplasts.The material within the chloroplast is called the stroma, corresponding to the cytosol of the original bacterium, and contains one or more molecules of small circular DNA. It also contains ribosomes however most of its proteins are encoded by genes contained in the host cell nucleus, with the protein products transported to the chloroplast.

In vascular plants, phloem is the living tissue that carries organic nutrients ( known as photosynthate), particularly sucrose, a sugar to all parts of the plants .

Photosynthesis requires three essential components: sunlight as the energy source, chlorophyll to capture light energy, and carbon dioxide plus water as raw materials. All these conditions are necessary for the process to occur, making D the correct answer.

The question describes the exact definition of photosynthesis - green plants producing food from CO2 and water using sunlight in chlorophyll's presence. This matches option A perfectly.

Mg is present in chlorophyll and helps in photosynthesis. It is helpful in activation of some enzymes. It also act as an information carrier.

Plastocyanin is a copper containing protein involved in electron transfer. Amicyanin is a type I copper protein that plays an integral role in electron transfer.

Chromoplasts are colored plastids that contain various pigments. Chloroplasts are a specific type of chromoplast that contain the green pigment chlorophyll, which is essential for photosynthesis.

Both a and b are correct. Phaseolus vulgaris and Daucs carota can fix carbon monoxide and can reduce CO pollution.
