Biology Lecture: Cell Structure and Functions

Biology Lecture: Cell Structure and Functions

Chapter 1: Introduction to Cells

Cells are the basic structural, functional, and biological units of all living organisms. They are often called the

building blocks of life.

Chapter 2: Cell Types

There are two main types of cells: Prokaryotic and Eukaryotic. Prokaryotic cells lack a nucleus and

membrane-bound organelles. Eukaryotic cells have a nucleus and specialized organelles.

Chapter 3: Cell Membrane

The cell membrane controls the movement of substances in and out of cells and organelles. It consists of a

phospholipid bilayer with embedded proteins.

Chapter 4: Nucleus

The nucleus contains most of the cell's genetic material and regulates gene expression and cell division.

Chapter 5: Mitochondria

Known as the powerhouse of the cell, mitochondria generate ATP through cellular respiration.

Chapter 6: Other Organelles

Other important organelles include the endoplasmic reticulum, Golgi apparatus, lysosomes, and ribosomes,

each with specific roles in cell function.
