Cell Lives Objectives

List the steps involved in taking a cell from the body and preparing it for examination under the microscope.
Provide examples of cells that have different structures related to their functions.
Explain different cellular life stages, including mitosis, hypertrophy, differentiation, and apoptosis.

In this video Mark puts together many of the concepts covered so far in this guide: science discovery (exploring, describing, and explaining), microscopy, staining, and cellular structure.

The cheek cells are squamous (flattened) epithelial cells and they almost look like the “generic” round cell models. However, most cells in the human body have different shapes that match their functions. In each of the upcoming guide you will be introduced to different cells that form the tissues that make up organs.

This video uses easy-to-make models to describe the structures of some of the cells we’ll be studying under the microscope in upcoming guides.

A cell can change in structure and function in its lifetime.

These are four cellular life stages:

Mitosis

One cell divides and becomes two daughter cells.

Hypertrophy

A cell grows in size over time.

Differentiation

A cell changes its structure and function over time.

Apoptosis

A cell is programmed to die at a certain time.

This video discusses the various cellular life stages.
