In this question, you will have to write about vegetative propagation and support your answer with examples like:. Diagram showing the eyes of a potato. This question is about defining juvenile phase, reproduction phase and senescent phase. Question 9 asks students to write why higher organisms use the sexual reproduction method, though being complex.

These two questions ask the differences between zygote and zoospore, and gametogenesis and embryogenesis, respectively. Here, students will have to describe the changes that take place during post-fertilisation in flower.

This question is about the explanation of bisexual flowers, and asks the learners to collect five bisexual flowers from their surrounding areas, and seek for their scientific and common names.

It aims at explaining the living world in terms of scientific principles. It is important to note, however, that living things interact with the non living things in the environment as Well.

Biology, therefore also entails the study of non living things as well. The role of human beings in shaping the environment is also investigated in biology.

In summary, biology deals with the study of origins, types, nature, growth, development, interactions and maintenance of all life forms on earth. Branches of Biology Biology is such a broad field of knowledge.

It is divided into two broad branches 1. Zoology - This is a branch of biology that deals with the study of animal life. Botany - This is a branch of biology that deals with the study of plant life.

Within the two branches, there exist even smaller branches because the branches botany and Zoology are very wide and complex. The smaller branches of biology include: a Ecology - This is the study of the interrelationships between organisms and their environment. Ecology aims at establishing how organisms are related to each other and their environment. Ecology is further subdivided into smaller branches.

These can be forest ecology, marine ecology, rangeland ecology etc. It deals with the study of how variations differences occur between parents and their offspring.

It is also concerned with how various characteristics are passed on from parents to offspring. It deals with the processes that take place in the body of organisms.

Importance of biology The study of biology is very important. The knowledge acquired from this study can benefit an individual in myriad ways.

The study of biology is important in that: The knowledge acquired from the study of biology can be very helpful in solving environmental problems such as food shortage, poor health services, pollution and environmental degradation. The study of biology can grant one an entry into various careers such as medicine, veterinary medicine, animal husbandry, horticulture and dentistry.

The study of biology leads to development of scientific skills which are very useful in life. These include skills of observing, identifying, recording, classifying, measuring, analyzing and evaluating. These skills can enable one learn how to make right choices and lead an improved life. Through the study of biology man learns the causes of human, plant and human diseases and how best these diseases can be prevented and cured. Biological knowledge acquired in the study of biology is very useful in enhancing international cooperation.

Characteristics Of Living Things Living things share a lot of characteristics in common. These characteristics are discussed below.

Living things require nutrients for various purposes; growth, repair of worn out tissues and for provision of energy. Plants manufacture their own food using light energy, carbon IV oxide, water and mineral salts through the process of photosynthesis.

Conversely, animals feed on already manufactured foods from plants and other animals. During respiration, oxygen is used while energy, carbon IV oxide and water are released.

Respiration occurs in all living cells. The energy produced in living things is very useful as it enables the living things carry out some of their physiological processes. The energy is also required for growth and development, movement and repair of worn out tissues.
