The Wonder of Cells

By Tara Pierre

What Is a Cell?

Cells are basic building blocks of living things. Humans are made up of trillions of cells, with their own specialized functions. They have adapted over billions of years, due environmental changes.

You will soon know the wonders of cells, and the way that they work in their different functions. Enjoy the ride!

Ribosomes

These protein builders arrange the cells. These connect one Amino Acid ( are biologically important organic compounds containing amine, and carboxylic acid functional groups, along with a side-chain, specific to each amino acid) at a time, to build a long chain. Ribosomes are important because they contain protein, which is very important for cell growth and reproduction.

Nucleus

The Nucleus is a cell membrane, with a bound structure, that contains the cells hereditary information. With that, it controls cell growth and cell reproduction. There are 5 parts of this cell membrane, and they are:

1. Nuclear Envelope- which encloses the contents of the nucleus during a cell's life-cycle.

2. Nuclear Pore- allows the transport of molecules across the nuclear envelope.

3. Nucleolus- makes ribosomal subunits from proteins and ribosomal RNA, then sends the subunits out to the rest of the cell where they combine into complete ribosomes.

4. Chromosomes- made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.

5. Chromatin- substance of a cell nucleus, consisting of DNA, RNA, and various proteins, that forms chromosomes during cell division.

6. Endoplasmic Reticulum- While the function of the nucleus is to act as the cell brain, the ER functions as a manufacturing system.

Cytoplasm

This is a thick solution that fills each cell and is enclosed by the cell membrane. It's composed of water, salts, and proteins. It's fluid that fills the cell. Before, scientists called it the protoplasm.

Mitocondria

These organelles act like a digestive system , that takes in nutrients, breaks them down, and creates energy molecules for the cell. They are tiny organelles, that float freely throughout the cell. Muscle Cells have many of these!

Cell Membrane

Consider this as a bag. It keeps things inside. But, it has holes. All cells have a cell membrane that keeps all of the little pieces inside. The membrane holds cell pieces and fluids, but keeps the bad stuff away.
