CellsThe basic building blocks of life

What Are Cells?• What do you Know about

cells?• Are there different types

of cells?• What are different types of

cells?• Why are they important?• Are there different parts

of cells?

What are Cells?• Cells are the basic building blocks of life• They provide structure for the body,

take in nutrients from food, convert those nutrients into energy, and carry out specialized functions• Cells have many parts, each with a

different function.• these parts are called organelles that have

specialized structures and perform certain tasks within the cell

• Examples of cells: Skin cells, blood cells, nerve cells, sex cells, fat cells, cancer cells

Two Types of cells•Prokaryotic cells• organisms without a cell nucleus or any other membrane-bound organelles.

•Eukaryotic cells• organisms whose cells are organized into complex structures by internal membranes and a cytoskeleton. The most characteristic membrane bound structure is the nucleus

What are the differences between Eukaryotic and Prokaryotic cells?

We will be focusing on Eukaryotic cells

What are found in cells?• All cells contain Organelles• Organelles are small structures found

in cells with specialized functions

Organelles and their Function •Nucleus: the Boss! control center of cell. Also houses DNA

• Cell membrane: separates cells contents from environment. semi permeable• Cytoplasm: Jelly like substance inside the cell. (made of

water, salt and proteins)•Mitochondria: Produces energy for the cell; the “power

house!” of the cell• Rough ER: transport and storage, and is lined with

ribosomes• Ribosomes: makes proteins

Organelles and their Function (cont.)•Golgi Apparatus: synthesis, packages and

releases proteins or lipids. Like UPS

•Centrioles: where cellular division and reproduction occur•cytoskeleton: Supports structure and helps move

proteins•Lysosomes: contains enzymes for digestion•Vesicle: “vehicle”, moves proteins, lipids and

carbohydrates throughout cell

Animal Cell

With your neighbor, label as many organelles as you can

What about plant cells?• Plant cells and animal cells are similar, BUT NOT

exactly alike. • There are both different and similar organelles found

in plant and animal cells• What are some of the differences?

Organelles found in plants, and not animal cells•Cell Wall: the outer most

membrane of the cell, provides support and protection •Vacuoles: storage

compartments for nutrients •Chloroplast: where light

is captured and converted to energy (photosynthesis)

Compare and Contrast Plant and Animal Cells using a vendiagram. Then discuss with your neighborPlant Similarities Animal
