Slide 2 Slide 3 A cell is the basic unit of structure and function of all living things. We are made of TRILLIONS of cells! All humans, animals, plants, and bacteria are made of cells! Slide 4 A cell has many different parts that help it function. These are called organelles. Organelles have structure (how its built) and a function (what it does). Slide 5 The cell membrane is the outer layer of the cell that works as a screen allowing nutrients, water, and oxygen in the cell while keeping harmful substances out. Slide 6 The cytoplasm is a gel-like fluid that holds all organelles allowing them to move and function properly. Slide 7 The mighty mitochondria is considered the powerhouse of the cell because it helps the cell break down nutrients creating energy for the cell. Slide 8 Golgi bodies function as a post office for the cell because it helps package up proteins and nutrients to ship off to other parts of the cell. Slide 9 The nucleus is considered the brain of the cell because it controls what each cell does and becomes. DNA is located in the nucleus of every cell. Slide 10 The nucleolus is part of the nucleus. Ribosomes are created here. Slide 11 The endoplasmic reticulum serves as a transport system or highway for proteins and other organelles to move about the cell. There is rough and smooth endoplasmic reticulum. The rough ER is studded with ribosomes, the smooth ER is not. Slide 12 Ribosomes function as little protein factories, producing proteins to aid in cell function. Slide 13 Lysosomes can be compared to a recycling center. They break down nutrients, molecules, and waste materials for different purposes. Slide 14 Vacuoles are the storage tank for the cells storing energy, food, water, etc. Plant cell have one large vacuole while animal cells have multiple small vacuoles. Slide 15 Chloroplasts are only found in plant cells. Chloroplasts take in sunlight and transforms it to energy for the plant (photosynthesis occurs here). Chloroplasts are the reason why leaves and other plants are green in color. Slide 16 A cell wall is only found in a plant cell & provides extra support & protection for the plant cell.
