Cells are the structural and functional units of all living things. Cells come in many shapes and sizes, and are composed of a variety of organelles that carry out specialized tasks. Cells are capable of reproduction, growth, and response to their environment.
Cells: The Basic Unit of Life
3. Slide

Cells are the basic building blocks of all living organisms. There are two main types of cells, prokaryotic and eukaryotic. Prokaryotic cells, like bacteria, lack a nucleus and other membrane-bound organelles. Eukaryotic cells, like those in plants and animals, have a nucleus and various organelles that perform specific functions within the cell.
Different Types of Cells

A prokaryotic cell is a type of cell that lacks a nucleus and other membrane-bound organelles. These cells are found in bacteria and archaea, and are often smaller and simpler in structure than eukaryotic cells. Prokaryotic cells have genetic material in the form of circular DNA, and can reproduce through binary fission.

Bacteria are microscopic organisms that exist everywhere on earth. They can be harmful, causing infections and diseases, but some strains of bacteria are necessary for human health and play important roles in food production and environmental processes. Bacteria reproduce via asexual reproduction Bacteria often have different organelles that allow for there function and survival, like flagella that allow some bacteria to move

The nucleus of a cell is made up of genetic material, also known as DNA, which is what determines the characteristics of the cell. Cells are able to communicate with one another by releasing chemicals known as hormones. Cells contain tiny structures called organelles, which are specialized to perform certain functions within the cell.

Cell Membrane: The cell membrane is a biological membrane that separates the interior of all cells from the outside environment. It is composed of a phospholipid bilayer with embedded proteins. Cell Wall: The cell wall is a thick layer found on the outside of plant cells, bacteria cells, fungi cells, and some other eukaryotic cells. Its primary function is to provide structural support and protection for the cell. Cytoplasm: Cytoplasm is the material inside the cell membrane that contains the organelles and other cellular structures. It is a gel-like substance composed of proteins, water, salts, carbohydrates, and enzymes.

Plant cells are eukaryotic cells, meaning they have a nucleus and other membrane-bound organelles. Plant cells have a cell wall made of cellulose that acts as a protective layer and helps them maintain their shape. Plant cells contain chloroplasts, which are the sites of photosynthesis and the production of food for the plant.

Animal cells are made up of different organelles that work together to keep the cell functioning. Organelles include a nucleus, endoplasmic reticulum, mitochondria, and more. These cells are found in all multicellular organisms, such as plants and animals.
Animal Cells: An Introduction
16. Slide
60 seconds
Plant cells contain chloroplasts which are responsible for converting light into energy during photosynthesis. Animal cells have lysosomes which contain digestive enzymes that break down organic material. Plant cells have a cell wall which is composed of cellulose, a strong sugar molecule, while animal cells do not have a cell wall.

Animal cells contain structures called cilia, which are tiny hair-like projections that help the cell move. The nucleus of an animal cell is the only organelle that contains DNA. The plasma membrane of an animal cell is composed of lipids and proteins that regulate what enters and leaves the cell.

Plant cells have a cell wall and chloroplasts, which are used to make food from sunlight. Animal cells lack a cell wall and chloroplasts, and must get food from other sources. Both plant and animal cells have a nucleus, cytoplasm, and other organelles.
