FLASHCARD CHAPTER 4 BIOLOGY FORM 4

Front

What is the primary focus of Chapter 4 in Biology Form 4?

Back

Chapter 4 typically covers topics related to cellular biology, including cell structure, function, and processes.

Front

Define the term 'cell membrane'.

Back

The cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

Explain the role of mitochondria in cellular respiration.

Back

Mitochondria are known as the powerhouse of the cell, where they convert nutrients into energy through the process of cellular respiration.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and membrane-bound organelles.

Front

What is osmosis?

Back

Osmosis is the movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

Describe the process of photosynthesis.

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the significance of the cell cycle?

Back

The cell cycle is crucial for growth, development, and repair in organisms, as it regulates cell division and replication.

Front

Define 'enzyme' and its role in biological reactions.

Back

An enzyme is a protein that acts as a catalyst to accelerate chemical reactions in the body without being consumed in the process.

Front

What is the function of chloroplasts in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy stored in glucose.
