Key Topics in SPM Biology 2013 with Sample Questions and Answers

To better understand what to expect, here are some major topics with example questions and detailed answers based on the 2013 syllabus and past exam patterns.

Cell Structure and Function

Sample Question:

Describe the differences between prokaryotic and eukaryotic cells.

Answer:

Prokaryotic and eukaryotic cells differ in several aspects:

• Nucleus:
• Prokaryotic cells lack a true nucleus; their genetic material is free in the cytoplasm.
• Eukaryotic cells have a well-defined nucleus enclosed by a nuclear membrane.

• Cell Size:
• Prokaryotic cells are generally smaller (1-10 μm).
• Eukaryotic cells are larger (10-100 μm).

• Organelles:
• Prokaryotes lack membrane-bound organelles like mitochondria, endoplasmic reticulum, and Golgi apparatus.
• Eukaryotic cells contain these organelles, which perform specialized functions.

• Cell Wall:
• Prokaryotic cell walls are primarily made of peptidoglycan.
• Plant eukaryotic cells also have cell walls made of cellulose, whereas animal cells do not.

• Reproduction:
• Prokaryotes reproduce asexually via binary fission.
• Eukaryotes reproduce through mitosis and meiosis.

Genetics and Heredity

Sample Question:

Explain the role of DNA in inheritance.

Answer:

DNA (Deoxyribonucleic Acid) is the hereditary material that carries genetic information in all living organisms. Its primary role in inheritance includes:

• Storage of Genetic Information:

DNA contains the instructions necessary for the growth, development, and functioning of an organism.

• Transmission of Traits:

During reproduction, DNA is replicated and passed from parents to offspring, ensuring the transfer of genetic traits.

• Genetic Code:

The sequence of bases (adenine, thymine, cytosine, guanine) encodes specific proteins, which determine inherited characteristics.

• Replication:

Before cell division, DNA undergoes replication, ensuring each daughter cell receives an identical copy.

• Mutation:

Changes in DNA sequences can lead to variation, which is essential for evolution and adaptation.

Ecology and Environment

Sample Question:

Describe the importance of a food chain in an ecosystem.

Answer:

A food chain illustrates the transfer of energy and nutrients from one organism to another within an ecosystem. Its importance includes:

• Shows the Flow of Energy:

It demonstrates how energy is transferred from producers (plants) to consumers (herbivores and carnivores).

• Maintains Ecological Balance:

Helps understand predator-prey relationships and population control.

• Identifies Key Species:

Indicates the roles of producers, consumers, and decomposers in maintaining ecosystem health.

• Educational Tool:

Aids in understanding the complexity of food webs and the interdependence among organisms.
