A Correct answer
Explanation

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.

Multiple choice

Which of the following conditions is necessary for photosynthesis?

  1. Sunlight

  2. Chlorophyll

  3. Carbon dioxide and water

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

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.
