Today's Lesson

Welcome to Cells and Basic Biochemistry! In this lesson, we'll explore how to review: cells as basic unit of life. Scientific inquiry allows us to investigate and explain natural phenomena.

A cell is the smallest unit of life—the basic building block of all living things. Some organisms, like bacteria, are made of just one cell. Others, like humans, are made of trillions of cells! Each cell has parts that do different jobs: the nucleus controls the cell, the cell membrane holds it together, and other parts help with energy and growth. Think of cells as tiny factories that keep life going!

As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.

Take notes on key points and make connections to what you've already learned in previous lessons.
