A biology essay would essentially discuss different plant and animal life forms. It can also explain experiments that are conducted to prove a life theory and are written with different levels of understanding of the subject and the class you study in.
Before beginning writing study the required textbooks and understand various concepts. You would be expected to write the assignment as per different styles such as MLA, Harvard, APA, etc. and it must be written within the specified number of words. A number of resources are available in the form of books, journals and online resources. If you need to refer to these resources, be sure to provide the proper citation to them. If citation were not given, then the paper would be called as plagiarized. It should have an introduction, a body, a conclusion and a separate page where the resources are listed. This is called a structured format for writing.
A biology essay for a high school student would explain basic concepts. It would answer questions on topics such as cell division, mitosis and meiosis, chromosome, simple life forms such as amoebas and other single cell life forms. You may also have to explain concepts of hereditary, sexual and asexual reproduction, evolution theory and so on. An undergraduate student would be expected to conduct experiments and create a lab journal where observations and readings would have to be noted.
The biology paper has a better impact when it is written along with illustrations and drawings. Free drawing software is available and MS Word also has features that let you create simple drawings. Again, it is important to give a reference to the source from where the drawing was used. Students studying in graduate programs would be dealing with specialized biology subjects such as botany, zoology, genetics and so on and the level of writing expected here is higher.
In our team of writers there are many members who have served as biology teachers in various schools and colleges. All of them are native English speakers and have a through understanding of the subject. The documents we write is properly structured and references are given as needed. We have collectively written hundreds of essays for high school students as well as undergraduate and college students, studying in UK and US colleges.
We understand the requirements and objectives of the assignment and the academic level to which it should be written. We then plan the document and give it a proper structure, decide what goes into it and then gather the required resources. This methodology ensures that you get high grades and we have hundreds of satisfied customers who express their thanks for the writing services that we provide. Along with biology essay we also writeessays on many topics related to maths, science, chemistry, physics, history, law and many more.

What are Tissues?
The word tissue is derived from a Latin word meaning to “weave.” Cells that make up tissues are sometimes “woven” together with extracellular fibers.
Likewise, a tissue can sometimes be held together by a sticky substance that coats its cells.
There are four main categories of tissues: epithelial, connective,muscle and nervous. Let’s take a look at epithelial tissue.
Epithelial Tissue
Epithelial tissue covers the outside of the body and lines organs and cavities. The cells in this type of tissue are very closely packed together and joined with little space between them.
With a tightly packed structure we would expect epithelial tissue to perhaps serve some type of barrier and protective function and that is certainly the case.
Epithelial tissue helps to protect organisms from microorganisms, injury, and fluid loss.
In an epithelium, the free surface is usually exposed to fluid or the air while the bottom surface is attached to a basement membrane.
Classifying
Epithelia are commonly classified based on the shape of the cells on the free surface, as well as the number of cell layers. Sample types include:
Simple Epithelium: A simple epithelium has a single layer of cells.
Stratified Epithelium: A stratified epithelium has multiple layers of cells.
Likewise, the shape of the cells on the free surface can be:
Cuboidal
Analogous to the shape of dice.
Columnar
Analogous to the shape of bricks on an end.
Squamous
Analogous to the shape of flat tiles on a floor.
By combining the terms for shape and layers, we can derive epithelial types such as stratified squamous epithelium or simple columnar epithelium.

The heart is the organ that supplies blood and oxygen to all parts of the body. It is about the size of a clenched fist, weighs about 10.5 ounces and is shaped like a cone. The heart is located in the chest cavity just posterior to the breastbone, between the lungs and superior to the diaphragm. The heart is surrounded by a fluid filled sac called the pericardium. Blood is pumped away from the heart through arteries and returns to the heart through veins. The major artery of the body is the aorta and the major veins of the body are the vena cava.

Chambers
The heart is divided by a partition or septum into two halves. The halves are in turn divided into chambers. The upper two chambers of the heart are called atria and the lower two chambers are called ventricles. Valves allow blood to flow in one direction between the chambers of the heart.
Heart Wall
The heart wall is divided into three layers:
- Epicardium
- Myocardium
- Endocardium
Cardiac Conduction
Cardiac conduction is the rate at which the heart conducts electrical impulses. Cardiac muscle cells contract spontaneously and are coordinated by nodal tissue, specifically the sinoatrial node. There are other factors that influence heart rate as well. These include endocrine hormones, body temperature and exercise.
Cardiac Cycle
The cardiac cycle is the sequence of events that occur when the heart beats. There are two phases of this cycle:
- Diastole – Ventricles are relaxed.
- Systole – Ventricles contract.
