Study Guide for Exam (Labs 2–7)

These flashcards cover key concepts from Labs 2 to 7, providing a comprehensive review for the exam.

What is the purpose of oil immersion in microscopy?

It replaces the air gap between the lens and slide, increasing resolution and brightness.

What are the main differences between prokaryotes and eukaryotes?

Prokaryotes are unicellular, undergo binary fission, and lack membrane-bound organelles; eukaryotes are multicellular, undergo meiosis/mitosis, and have membrane-bound organelles.

What are the functions of the lysosomes?

Lysosomes are responsible for digestion and recycling of cellular waste.

What is the primary function of erythrocytes in the blood?

Erythrocytes are responsible for transporting gases such as oxygen and carbon dioxide.

What does the cardiac cycle consist of?

The cardiac cycle consists of systole (contraction) and diastole (relaxation) phases.

What happens during the phase of cytokinesis in cell division?

Cytokinesis is the process where the cell splits into two daughter cells after mitosis or meiosis.

What is the normal range for blood pressure?

The normal blood pressure range is 120/80 mmHg.

What occurs during expiration?

During expiration, the diaphragm relaxes, the chest decreases in size, pressure increases, and air is expelled.

What is the role of the Golgi apparatus in a cell?

The Golgi apparatus modifies and packages proteins for secretion or delivery to other organelles.

What does Boyle's Law describe in terms of gas behavior?

Boyle's Law states that pressure is inversely related to volume; as volume increases, pressure decreases.
