What cells and organelles means

You learn the main parts inside plant and animal cells and what each part does. This helps you understand how living things work and answer questions about cell structure in junior high science.

What you will practise

  • Name cell parts from short science questions
  • Match organelles to their jobs in the cell
  • Identify parts found in plant cells only
  • Distinguish plant cells from animal cells
  • Choose the correct answer from similar cell terms

Before you start

You should already know the idea that living things are made of cells. It also helps if you can read simple diagrams and follow basic science terms.

Worked example

One question from this skill's own question bank, shown with its full working.

Question

Which organelle is known as the powerhouse of the cell?

  • Nucleus
  • Mitochondria
  • Ribosome
  • Cell wall
Answer: Mitochondria

Working: Mitochondria release energy through respiration, earning the nickname "powerhouse".

Common mistakes to avoid

  • Confusing the nucleus with the cell wall. The nucleus controls the cell, while the wall supports plant cells.
  • Mixing up mitochondria and other organelles. Remember that mitochondria release energy.
  • Thinking animal cells have a cell wall. Only plant cells have a rigid cell wall.
  • Forgetting that DNA is kept in the nucleus. Do not place genetic material in the cell membrane.

Curriculum and exam alignment

Ghana GES Basic 7 to 9 syllabusBECE

This topic usually appears in junior high biology under cells, living organisms, or basic life processes. It supports BECE preparation by building the foundation for questions on cell parts and their functions.

Curriculum notes are a general guide to where this work normally sits. Always check the syllabus your school or examination body is currently using.
