How to learn biology|6 Effective and Easy ways

Biology is a subject of science which deals with the knowledge of living creatures.

This includes the study of both plants and animals in the nature.

It starts from smallest possible forms of plants and animals to the highly evolved forms.

The branch of biology dealing with plants is termed BOTANY.

And that dealing with animals is called ZOOLOGY.

The branch dealing with especially micro-organisms is called microbiology.

The subject deals in detail about birth, growth, reproduction, physiology and anatomy etc.

How to learn biology?

1. Have the diagrams or 3D structures: Biology can be understood better by use of diagrams or 3D structures of animals or plants. Since there is explanation about different parts of the anatomy or physiology, it has be seen first. Seeing them helps us to have a better memory of the part. Also it helps us understand what are the functions of that organ or part. how to learn biology

Further diagrams improve the memory of the subject. So you can see that the memory of that topic is better than that which you have read without the diagram.

2. Understand the terminology: The scientific terminology used in biology seems to be tough. This may be one of the reasons why some of them do not like it. But in fact, the terminology needs to be understood to make it easy.

Many of the scientific words in biology are from Latin or Greek. So if you understand the actual meaning of the word in those languages, it becomes easy to remember and understand.

For example the word “meta” means “next“. So in the word “metamorphosis”, meta means next. So it is meta+morpho+osis i.e next+physical+condition (state). Similarly, metaphase (a stage in cell division) means again “next” phase. So if you come across the word “meta” it always means next.

So try to understand the meaning of  words in the terminology. This makes it easy for your understand and also memorize any terms in course of study.

Some of the terms which one needs to understand are

amphi = both (amphibians = amphi+bians; means “both+living” ex: frogs, live both on land and water)

apo = Tip

teleo = Tail

artho = many (ex: arthopods = artho = many+ podos= foot).

some = also called “somes” means part.

There are many and try to understand and remember the terms. This will help you learn biology in a very easy manner.

3. Use natural comparisons: Also instead of just reading it from books use daily life activities. When you come across some physiology, metabolism, etc. see from daily experiences. This makes you understand and remember better. For example the beating of heart can be heard by self. You can even count number of beats for a minute. This makes you realize that the actual numbers are same as that mentioned in book. This makes you confident and also the knowledge more reliable.

So always use real life examples where possible to study biology.

4. Use laboratory: Using laboratory for many of the lessons is a good way to study biology. Since it is a science subject, like physics and chemistry, biology needs laboratory demonstrations.

Use of laboratory to study biology helps to enhance your interest and curiosity in the subject. Many experiments are done in lab. Some of them like staining of plant tissue slices, observation of animal tissues in slides, dissection of earthworms etc, helps understand the anatomy and physiology better. So it good to never bunk or miss a biology related lab work.

5. Read and revise: Once a particular chapter is discussed in classroom, it is better to revise it the same day at home. This helps you understand better and also clarify any doubts from your teacher the next day. Also it helps you memorize better and will be easy to get better results in exams.

But for this it is wise to always read from a standard Biology book. Since there are images and flow charts, having a book helps to memorize better.

How to read biology in detail manner:

As we discussed before, biology deals with every aspect of living beings. So one has to read it in different aspects like

1. Anatomy: It describes the structure of the bodies of plants, animals, microbes in detail manner.

For this one needs to know basics like Cell, tissue, organs etc.

Each cell has cell organelles like nucleus, cell membrane, ribosomes, golgi bodies, micortubules, mitochondria, etc.

Even one need to differentiate plant cell and animal cells as they are quite different.

Similar set of cells make up tissues. A group of tissues make up organs and organ systems. A group of organs make up an organism or animal. So different cells make different tissues, and glands.

“The anatomy is the primary factor by which one can differentiate the animals or plants”.

For instance aves (birds) have wings and two legs while insects have similar wings but many legs. Heart of reptiles is mostly 3 chambered while that of mammals is four chambered.learn biology

In plants there are simple leaves i.e. single big leaf and some have compound leaves which means a single leaf is differentiated into many small leaflets.

2. Physiology: This is next important factor to differentiate animals and plants. Physiology is the process by which anatomy of the plant or animal is maintained.

The physiology includes how an animal digests food, gets energy, method of reproduction, cell division, cell death etc.

The material like carbohydrates, amino acids, proteins, fats, vitamins, minerals  and nutrients are utilized in the process of physiology.

How food is converted to energy, how energy is used up in the body, role of enzymes, hormones in physiology.

Since 80% of animal and plant anatomy is made up of water. You can see its role in physiology and anatomy. Importance of water.

For example poikilothermic  animals have body temperature varying as per surroundings while that of isotherms have same or fixed temperature at all climates.

3. Taxonomy: Taxanomy is a way by which plants, animals and microbes are categorized for ease of study and description. For example mammals are a category of animals which breed their siblings by milk.

4. Life cycles: All living creatures have certain life cycles like birth, growth, reproductive phase and death. Some insect have egg, larva and then insect stages. So life cycle indicates how animal progresses in its life with reference to anatomy and physiology.

5. Morphology: This tells how animals appear externally. Because of morphology one can easily differentiate fish from tortoise in water.

6. Habits and habitats: Not all animals and plants are present all over the world.

They are present at places most suitable to them. Ex: Kangaroos are found mostly in Australia but not in Asia etc.

Amphibians like to reproduce mostly during rainy season and this is their habit.

To learn biology one should

  1. Have a standard text book for reference.
  2. Have a class notes written properly
  3. Draw and practice diagrams with proper labeling of parts in the diagram.
  4. Try to memorize the Greek or Latin terms as they seem to be tough to remember.
  5. Try to compare the aspects like physiology, anatomy of one species or family with another. One needs to know clear demarcation between the plants or animals.

Ex: Monocotyledons and dicotyledons. Monocotyledons have unbreakable seed while dicotyledons have a seed which is breakable into two exact halves.
