<h3>What is carbon dioxide?</h3>
Carbon dioxide is one of the gases that cycle around in the universe. It is an integral part of the carbon cycle. The carbon cycle is a model that depicts the movement of carbon in the ecosystem.
The natural source of carbon dioxide that was left out is the calcareous shells of organisms. The major metabolic process that was left out is respiration.

Cellular communication is the function of the plasma membrane that allows it to respond to certain stimuli from outside the cell and hormones to bind to receptors.
<h3>What is plasma membrane?</h3>
It is a double layer of lipids that covers and delimits the cells, serving as a border between the inside and the outside of the cell, and also allowing a physicochemical balance.
<h3>Characteristics of plasma membrane</h3>
Enables the development of compartments; allows or rejects the entry and/or exit of particles; acts as a mechanical defense; and reacts to external signals and stimuli.
It reacts and transmits information inside the cell, starting certain biochemical processes: cell division, cell movement or the segregation of biochemical substances.
Therefore, we can conclude that the main characteristic of the plasma membrane, that is, its ability to allow or reject the entry of certain molecules into the cell.

Answer:
The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason.
New cells are born through the division of their “parent” cell, producing two “daughter” cells from one single “parent” cell.
Daughter cells start life small, containing only half of the parent cell’s cytoplasm and only one copy of the DNA that is the cell’s “blueprint” or “source code” for survival. In order to divide and produce “daughter cells” of their own, the newborn cells must grow and produce more copies of vital cellular machinery – including their DNA.
The two main parts of the cell cycle are mitosis and interphase.
Mitosis is the phase of cell division, during which a “parent cell” divides to create two “daughter cells.”
The longest part of the cell cycle is called “interphase” – the phase of growth and DNA replication between mitotic cell divisions.
Both mitosis and interphase are divided into smaller sub-phases which need to be executed in order for cell division, growth, and development to proceed smoothly. Here we will focus on interphase, as the phases of mitosis have been covered in our “Mitosis” article.
Interphase consists of at least three distinct stages during which the cell grows, produces new organelles, replicates its DNA, and finally divides.
