Cells have many similarities between different species. Example: Mitochondria can be found in the cells of humans, dogs, spiders, trees, etc. Cells are the basic unit of structure and function in all living things. Cell Structure Cells form parts of your organs. It gives your body its’ shape, size, strength. Cell Function Cells perform all of an organism’s tasks and functions.

Obtain oxygen and food get rid of wastes allow you to grow and repair. Cell Size Most cells are so small they are microscopic. Microscopic: can only be seen by the human eye with the help of a microscope. Approximately 100,000 skin cells fit in a square centimeter.

Approximately 250 million red blood cells are found in a drop of blood. Development of the Cell Theory The cell theory states the following: All living things are composed of cells. Cells are the basic units of structure and function in living things. All cells are produced from other cells. Unicellular vs. Multicellular Unicellular, or single- celled, organisms include bacteria, the most numerous organisms on Earth. Multicellular organisms, like this dog, are composed of many cells.

Unicellular Multicellular Advantages of Being Multicellular In multicellular organisms, cells are often organized into tissues, organs, and organ systems. This allows our cells to perform specialized and unique tasks. End of Section: Discovering Cells Section 2: Looking Inside Cells What role do the cell wall and cell membrane play in the cell? What is the role of the nucleus in the cell? What organelles are found in the cytoplasm and what are their functions? How do cells differ? Organelles (and other Cell Structures) Organelle: a tiny structure that has a specific function inside the cell, floating in the cytoplasm Found in Both Plant and Animal Cells Found Only in Plant Cells Animal Cells nucleus cell wall lysosomes cell membrane chloroplasts vacuoles (several small) cytoplasm vacuole (one large) endoplasmic reticulum ribosomes Golgi body mitochondria Plant and Animal Cells Cell Membrane NOT an organelle What is it?
