Cells:

Cells The basic building blocks of life

What Are Cells?:

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?:

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:

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?:

What are the differences between Eukaryotic and Prokaryotic cells? Prokaryotic cell Eukaryotic Cell

We will be focusing on Eukaryotic cells:

What are found in cells?:

What are found in cells? All cells contain Organelles Organelles are small structures found in cells with specialized functions

Organelles and their Function :

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.):

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?:

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:

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 neighbor:
