Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product.
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

Stem cells become specialized cells such as blood cells because certain genes are activated and cause a particular cell to develop (Option B). It is called differentiation.
<h3>What is cellular differentiation?</h3>
Cellular differentiation refers to the process by which certain genes are expressed in a particular cell lineage.
Cellular differentiation leads to the formation of mature specialized cells that perform specific functions.
For example, immature hematopoietic stem cells become differentiated to produce mature red blood cells.
