Introduction to Biology

Biology, as a school subject, is the study of life and living things. It focuses on plants, animals, humans, and microorganisms. Through Biology, students learn how life processes work, how living organisms interact with their environment, and the role they play in maintaining balance in nature. It is a subject that connects directly to everyday life, making it both interesting and practical for students.

There you have the answers to the objective section of Biology Exam Questions for SS1 first term. Use the comments section to let me know if you have any questions you would want me to clarify or discuss further.

Answers to Section B (Theory)

Question 1

1a. Define Fruticose lichens.

Fruticose lichens are bushy or shrubby lichens with branched structures that grow upright or hang down.

1b. Describe the association between the mycobiont and phycobiont in a lichen.
The mycobiont (fungal partner) provides protection and moisture, while the phycobiont (algal partner) carries out photosynthesis to produce food for the lichen.

Question 2

Question 3

3a. What is Systematics?

Systematics is the scientific study of the diversity of organisms and their evolutionary relationships.

3b. Why can’t the virus fit into any of the 5 kingdoms of classification?
Viruses cannot fit because they lack cellular structure, do not perform metabolic activities, and can only reproduce inside a host.

Question 4

How to Pass Biology Exam Questions for SS1 First Term

Here are some simple but powerful tips to help you pass your Biology exam questions for SS1 first term:

1. Know Your Syllabus Well

Start by going through your SS1 First Term Biology syllabus. This will help you to know the most important topics and focus on them. Don’t skip any section, no matter how small. Every part is a step to success.

2. Understand the Basics

In Biology, understanding concepts is key. Learn about cell structure, plant and animal classification, and the basics of life processes like nutrition and respiration. When you understand the basics, everything else becomes easier.

3. Practice Past Questions

Past questions are a great way to prepare. They give you an idea of how questions are framed and help you know the important areas to focus on. Practice answering them on time, so you get used to exam conditions.

4. Use Diagrams

Biology involves many diagrams, so practice drawing them. A clear, labeled diagram can earn you easy marks. Whether it’s a plant cell or the human digestive system, knowing how to draw it is a game-changer.

5. Stay Organized

When you are answering questions, make sure your work is neat and well-organized. Use bullet points or short paragraphs. This helps the examiner to follow your answers easily.

6. Take Care of Your Health

Eat well and sleep well before the exam. A healthy body supports a sharp mind. Don’t stay up too late studying the night before the exam. Rest well, and you’ll be ready to tackle any question.

7. Stay Confident

You’ve prepared, now trust your knowledge. When you walk into the exam hall, stay calm. Read each question carefully, and answer with confidence. You’ve got this!
