Snapshot of biology notes form 1

The study of biology is crucial as it helps students live a better life. Many of the lessons learned in biology notes form 1 gives learners a solid foundation on future biological undertakings. The following are free notes on different chapters explored in biology notes.

Introduction to biology

Biology notes form 1 begin with introduction to biology. Biology is derived from two Greek words bios meaning life and logos meaning study or knowledge. According to these words, biology means life knowledge. As an academic field, biology is the study of living things or organisms. There are two main branches of biology; botany and zoology. Botany is the study of plants while zoology deals with the study of animals. Other branches of biology include;

1. Microbiology- it is the study of microorganisms (microscopic)
2. Morphology- it refers to the study of external structure of organisms
3. Anatomy- deals with the study of internal organs or structure of organisms
4. Physiology- it entails the study of how cells or body works/ functions
5. Biochemistry- it involves the study of chemistry of materials in living organisms
6. Cytology- this is the study of cells
7. Genetics- a branch of biology that deals with inheritance
8. Ecology- a branch that studies the relationship between organisms and their environment
9. Taxonomy- it deals with classification of organisms; sorting them into groups
10. Histology- it is the study of fine structure of tissues
11. Virology- deals with the study of viruses
12. Bacteriology- the study of bacteria
13. Entomology- a branch of biology that deals with study of insects
14. Ichthyology- it is the study of fish

What is the importance of biology?

Studying biology has immense benefits to learners. The following are benefits of studying biology;

1. Biology helps learners understand how the human body functions
2. It helps learners understand the developmental changes that occur in the body
3. Studying biology contributes to improved life
4. The study of biology opens up diverse career possibilities including; medicine, nutrition, public health, dentistry, agriculture, biochemistry, teaching, research, environmental science and more.

Characteristics of living organisms/ things

Living things or organisms portray certain characteristics or attributes not present to non-living organisms. These are the characteristics that define living organisms. The following are activities performed by living things.

1. Nutrition- it is the process in which nutrients or food are manufactured and utilized by living organisms. Green plants and certain bacteria produce their own food. All other living organisms feed on complex organic substances
2. Respiration- is the process in which food is broken down to release energy. The energy produced is used for various activities by the organism
3. Gaseous exchange- this is the process in which gases (carbon dioxide and oxygen) are taken in and out of living organisms through respiratory processes
4. Excretion- it is the process in which metabolic wastes are removed from the body. Body excretion comprise of urea, carbon dioxide (carbon (IV) oxide) etc.
5. Growth and development- growth is defined as an irreversible change in size. Development is irreversible change in complexity. As living organisms grow, they increase in size. When living organisms grow and develop, they become more differentiated
6. Reproduction- it is the formation of new individuals of species to maintain continued existence and population growth
7. Irritability- it is the ability of organisms to detect and respond to changes in the environment. This attribute is of great survival to organisms
8. Movement- is defined as a progressive change in position from one place to another. Some living organisms are sessile (i.e. fixed to the substratum). For instance, majority of plants move only certain parts.
