Biology-Theory/Essay

WAEC Biology Questions and Answers 2023, In addition to the objective section, the Biology exam also includes a theory component. This section of the exam provides candidates with one hour and forty minutes to complete. It is divided into two parts, commonly referred to as Part 1 and Part 2.

In Part 1, all the questions are compulsory, meaning that candidates must answer every question in this section. The questions in Part 1 cover a range of topics and require thorough knowledge and understanding of biology concepts.

Part 2 of the exam offers candidates some flexibility. Here, candidates are given the option to choose two questions from the section and provide well-constructed answers. This allows candidates to focus on the topics they feel most confident in and demonstrate their depth of knowledge in those areas.

waec biology theory questions 2023

Waec biology theory questions are a type of examination questions that require a written response to demonstrate knowledge and understanding of biological concepts, principles, and theories. These questions typically involve explaining biological processes, describing structures and functions of biological components, analyzing experimental data, and discussing relationships between various biological phenomena. The purpose of biology theory questions is to assess a student’s comprehension and application of biological theories and their ability to articulate their understanding in a written format.

Review of WAEC Biology Objectives 2023/2024

The WAEC Biology examination for the year 2023 is structured into two sections, namely Section A and Section B. Section A consists of objective questions, typically comprising around 60 questions. On the other hand, Section B consists of essay questions, usually ranging from 6 to 7 questions.

Again, we present the WAEC Biology questions and answers for your reference and preparation.

1. Question: What is the function of the mitochondria in a cell?
Answer: The mitochondria are responsible for generating energy in the form of ATP through cellular respiration.

2. Question: What is the role of the ribosomes in protein synthesis?
Answer: Ribosomes are the cellular structures where protein synthesis occurs. They read the mRNA and assemble amino acids to form proteins.

3. Question: What is the process by which plants convert sunlight into chemical energy?
Answer: Plants perform photosynthesis, a process in which they use sunlight, carbon dioxide, and water to produce glucose and oxygen.

4. Question: What is the purpose of the circulatory system in humans?
Answer: The circulatory system transports oxygen, nutrients, hormones, and other essential substances throughout the body. It also helps in removing waste products.

5. Question: Name the two main types of nucleic acids found in cells.
Answer: The two main types of nucleic acids are DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). DNA carries genetic information, while RNA plays a role in protein synthesis.

Lastly, please note that these are sample questions, and the actual WAEC Biology exam may have different questions. It is recommended to study the complete syllabus and refer to official study materials for thorough preparation.

2023/2024 Biology Questions and Answers (Theory Paper 1)

Below are the Biology questions and answers for the 2023/2024 Theory Paper 1:

• Question 1:

Explain the process of mitosis in detail.

Answer:
Mitosis is a vital cellular process that results in the formation of two identical daughter cells. It consists of several distinct stages: prophase, metaphase, anaphase, and telophase.

During prophase, the chromatin condenses into chromosomes, and the nuclear envelope starts to disintegrate. The centrioles move towards opposite poles, and spindle fibers begin to form.

However, In metaphase, the chromosomes align along the equatorial plane of the cell. The spindle fibers attach to the centromeres of each chromosome, ensuring their proper positioning.

During anaphase, the sister chromatids separate and are pulled towards opposite poles by the shortening of the spindle fibers. This ensures that each daughter cell will receive an identical set of chromosomes.

Finally, in telophase, the chromosomes reach the poles of the cell. The nuclear envelope reforms around each set of chromosomes, and the spindle fibers disassemble. Cytokinesis, the division of the cytoplasm, follows, resulting in the formation of two individual daughter cells.

• Question 2:

Discuss the structure and function of the human respiratory system.

Answer:
The human respiratory system is responsible for the exchange of gases, facilitating the intake of oxygen and the removal of carbon dioxide. It consists of several key components, including the nasal cavity, trachea, bronchi, bronchioles, and lungs.

Furthermore, the respiratory process begins with inhalation, where air enters through the nasal cavity or mouth. The air then passes through the trachea, which branches into the bronchi, further dividing into smaller bronchioles within the lungs. These bronchioles terminate in tiny air sacs called alveoli, which are the main sites of gas exchange.

Finally, the diaphragm, a dome-shaped muscle at the base of the lungs, plays a crucial role in respiration. It contracts during inhalation, expanding the thoracic cavity and causing the lungs to expand, while relaxation of the diaphragm during exhalation allows for the expulsion of air.

• Question 3:

Describe the process of photosynthesis and its importance to plants and ecosystems.

Answer:
Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose (a form of chemical energy) and oxygen. It occurs in the chloroplasts, specifically in the chlorophyll-containing cells of plant leaves.

However, during photosynthesis, light energy is absorbed by chlorophyll, which energizes electrons in the chlorophyll molecule. These energized electrons participate in a series of complex reactions that ultimately produce ATP (adenosine triphosphate), which is the energy currency of the cell.

Again in simultaneously, water molecules are split, releasing oxygen as a byproduct. The released oxygen is crucial for sustaining aerobic life on Earth. The carbon dioxide taken in from the atmosphere is used to build glucose through a series of enzymatic reactions known as the Calvin cycle.

• Question 4:

Explain the process of protein synthesis in cells.

Answer:
Protein synthesis is a fundamental process in cells that involves the production of proteins, which are essential for various cellular functions. It occurs in two main stages: transcription and translation.

During transcription, the DNA sequence in the nucleus is transcribed into a messenger RNA (mRNA) molecule. The enzyme RNA polymerase binds to a specific region of DNA called the promoter, unwinds the DNA double helix, and synthesizes a complementary RNA strand based on the DNA template. The mRNA molecule is synthesized in the 5′ to 3′ direction and contains the genetic information encoded in the DNA.
