Which structure is the arrow pointing to?

What is the function of this organelle?

answer 1. The arrow is pointing to the "nucleus."

Explanation:

A cell is the smallest unit in an organism. It mainly functions to provide structure to the human body, thus it is called "the building blocks of life."

There are 6 organelles in a cell and these are Nucleus, Ribosomes, Endoplasmic Reticulum, Golgi Apparatus, Chloroplasts, and Mitochondria.

The arrow is pointing to the cell's nucleus in the image above. This is an organelle that is enclosed in a membrane. It is where you can find the deoxyribonucleic acid or the DNA, which is essential for hereditary function. It also coordinates activities in the cell, such as metabolism, synthesis of proteins, cell division.

Remember, not all cells have a nucleus. Only eukaryotic cells have a nucleus. These cells are considered more advanced.

2. An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
