Answer:
B- Photosynthesis
Explanation:
Chloroplasts are <em>chlorophyll-containing, eukaryotic cell structures</em> that function in photosynthesis by absorbing energy from sunlight, combining this energy with water and CO2 to convert them to sugars . This cell structure is known as a plastid. The sugars produced, are important for the survival of the plant.
Chloroplasts reproduce on their own, independent of the whole cell because they contain their own DNA. Plant chloroplasts are located in guard cells in plant leaves. Closely linked to these guard cells are tiny pores called stomata, which allow gas exchange required for photosynthesis.
Photosynthesis occurs in two stages:
- The light reaction stage
- The dark reaction stage
The Light reaction stage takes place in the presence of light. Clorophyll converts light into chemical energy in the form of ATP and NADPH. Both molecules produced, are used in the dark stage to produce sugar.
In the dark reaction stage, the stroma, containing enzymes, facilitates reactions leading to the production of sugars from ATP and NADPH. This process is also called the carbon fixation stage. The sugar produced can be stored in the form of starch for other processes such as respiration.

The principles of fossil succession and natural selection are connected to Rocks and fossil fuels respectively.
<h3>Define principle of Fossil Succession ?</h3>
A method for determining the relative age of a fossil is through fossil succession. It can put the fossils in chronological order by using the geological strata to identify the rock layers where they are located.
<h3>Principle of fossil selection .</h3>
The law of fossil succession, also referred to as the principle of fossil succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna and that these fossils succeed each other vertically in a definite, reliable order that can be recognized over considerable horizontal distances.
