Cell Structure and Organisation: แบบฝึกหัด

A student observes a cell under a light microscope and identifies a large central vacuole and chloroplasts. Which type of cell is being observed?

Red blood cells are specialized for the transport of oxygen. Which structural feature helps them carry the maximum amount of oxygen possible?

Which of the following correctly matches the cell structure to its function?

Which organelle is responsible for the process of aerobic respiration to release energy for cellular activities?

Which structural adaptation allows a red blood cell to transport more oxygen efficiently?

In a plant cell, what is the function of the large, sap-filled vacuole?

Compare one structural difference between a typical animal cell and a typical plant cell regarding their outer boundaries.

A root hair cell has a long, narrow protrusion. Explain how this specific adaptation supports its function in a flowering plant.

A student observes two different cell types under a light microscope. Cell A is a rectangular cell with a rigid outer layer and several green oval structures inside. Cell B is an irregular, spherical shape and lacks these green structures.

(a) Identify the kingdom of life Cell A likely belongs to and name the green structures observed.
(b) Compare the vacuoles found in Cell A and Cell B in terms of their size and permanence.

Specialised cells have unique structures that allow them to perform specific functions efficiently.

(a) Describe two structural adaptations of a red blood cell that enable it to transport the maximum amount of oxygen.
(b) Muscle cells contain a significantly higher number of a specific organelle compared to skin cells. Identify this organelle and explain why it is essential for the function of muscle tissue.
