What is the structure labeled with an arrow?

A. Cytoplasm
B. Nucleus
C. Cell wall
D. Flagellum

In the given diagram, the structure labeled with an arrow is the nucleus. Therefore, option (B) is correct.

The nucleus is the most integral component of the cell. A nucleus can be defined as a double-membraned eukaryotic cell organelle that consists of genetic material.

The nucleus is typically the most evident organelle in the cell. The nucleus is entirely bound by membranes and is surrounded by the nuclear envelope.

The contents of the nucleus distinguish from the cytoplasm by the membrane. The nucleus contains hereditary information about the cell and controls its growth and reproduction.

The nucleus is not just a storage section for DNA but also occurs to be the home of cellular processes. In the nucleus, DNA  can be duplicated and the process is named as named DNA Replication and produce an identical copy of the DNA.

In the diagram, the arrow indicates the nucleus.

A student asks a class the following question, “Polyethylene has a relatively short formula (C2H4) while nylon has a long formula (C12H22N2O2). However, in a toothbrush, the handle is relatively long while the bristles are relatively short. How is this possible?”

Choose the explanation below that best responds to the student’s question.


A
Molecules are so small that they cannot be seen with a naked eye. Therefore, being a slightly bigger molecule on that scale will not influence how big the part of the toothbrush is.

B
In a toothbrush, the polyethylene chain is most likely a longer chain of molecules than the nylon chain, making the handle longer than the bristles.

C
Polyethylene is used for the bristles and nylon is used for the handle, because the size of the molecule does determine the size of the object being built by the molecules.

D
Polyethylene has a short formula, but it makes a long chain. Nylon has a long formula, but it is fat, not long. That is why the nylon bristles are short while the handle is long and thin.
