Biology : The Scientific Study Of Living Things Essay

There are many different types of cells in the human body. These cells would not be able to function on their own, they are all part of a large organism that is called - you.

1. An understanding of chemistry is important for an understanding of biology because biology needs the models of chemistry to better describe life.

Without the cells there will be no life. A cell is the the building block of the body. There 2 different types of cells there are animal cell and plants cells. Eukaryote is any cell that has a cell membrane bound. It also contains organelles.

Biology explains what occurs within all living things. Chemistry explains the reactions between different substances at the molecular level. Physics, however, explains how and why everything occurs in the universe. Through the use of mathematics, physics explains why things must go down and why it is impossible to reach the speed of light. Physics simply mirrors my personality as I am an individual who enjoys an explanation for everything.

A cell is the basic unit of life, essential to maintaining the physiology of the larger organism. In animals, certain organelles metabolize food into energy, and then uses the energy for repair, growth and reproduction. Similarly, chloroplasts in plant cells transform sunlight into energy, a process known as photosynthesis.

Every living thing is composed up of cells that contain DNA. The cells are specialized to its own function. It can carry the information needed to make up the body and hands.

Cells are the basic units of structure and function in an organism, and Cells come only from the reproduction of existing cells.

Breaking down an organism leads scientists to identify cells. A group of cells create tissues, tissues combined are organs, and organs and their functions make up systems. Basically, cells make up living organisms. There are 2 kinds of cells: Prokaryotic and Eukaryotic. Within a prokaryotic, it doesn’t contain a DNA bounded nucleus; however, a eukaryotic cell does. Though the prokaryotic cell differs from a eukaryotic cell, they share a cell membrane. The cell membrane is composed of a phospholipid bilayer and proteins, which makes it selectively permeable. It is located outside of the cytoplasm and controls the movement of substances in and out of the cell. Its basic function is to protect the cell from its surroundings by selecting what can enter and exit the cell.

The human body is made up of 100 trillion cells. All cells have the same basic structure (see figure 1) however some cells are specialised to suit a specific purpose. An example of this is the pancreatic beta cells found in the islets of Langerhans. These cells are specialised to synthesise the protein insulin that is involved in the metabolism of glucose in the cells. (Layden, 2010)

Each cell contains the genetic coding that makes organisms function. A collection of similar functioning cells form tissues. Groups of tissues form organs, organs make systems and all of this together is the human body. Cells store DNA, which are the blueprints of the body. Humans have 46 chromosomes that come from parents; they create the genetic coding

The human body is made up of millions of tiny cells that can only be seen under a microscope, cell also vary in shape and size. Cells are the basic structural of all living things. The human body is poised of trillions of cells. They give structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of them. Cells all have different sizes, shapes, and jobs to do. Each cell has a different function. The actual definition of cells is the smallest structural unit of the body that is capable of

Cells are some of the smallest organisms around. All living things consist of cells, and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly.

In order for cells and organisms to “live” they need to perform certain tasks such as produce energy through respiration, send messages, maintenance and reproduction. To enable the cell to do so, it contains within small structures called organelles, each organelle is different and carries out a specific function.

In real life, organic chemistry is the cause for such products as rubber, vitamins, and paper, while synthetic products such as nylon can be attributed to inorganic chemistry. Analytical chemistry stretches across many fields, such as oil and petroleum, food and agriculture, forensics, and manufacturing. Meanwhile, physical chemistry is a bit narrower, but it is still involved in various fields such as pharmaceuticals and materials. Biochemistry in real life usually takes the form of research into the complexity of a being’s inner workings, and can pay off in such was as medicines or cures for diseases.

Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment, why they hold the different properties that depict them, how their atomic structure may be fathomed, and how they may be manipulated and changed.
