  3. Cell Organelles pg.3 • Organelles perform specific functions in cells. • All cells contain organelles that perform different functions within a cell. • Mitochondrion is the power house of the cell and is a organelle. • The nucleus contains DNA and inside the DNA are the genes. • The vacuole is a membrane-bound sac within a cell or tissues that stores water or other materials. • A plant cell usually has one large vacuole. • Ribosome is a organelle responsible for protein synthesis. • Cytoplasm is the jelly like substance in the cell. • Endoplasmic Reticulum is the network of passage ways in a cell. • Golgi Body- it receives materials and packages them and disperses them to other parts of the cell. • Lysosome break down food particles.

  4. Active and Passive Transport pg.4 • Active transport uses extra energy. • Passive transport doesn’t use any energy. • Diffusion is a type of passive transport and is the movement of molecules from an area of higher concentration to an area of lower concentration. • Osmosis – is another type of passive transport that involves the movement of water . • The definition of osmosis is the diffusion of water through the membrane that allows specific substances to pass through.

  5. Cellular Respiration pg.5 • Plant cells use carbon dioxide , water, and light to make food, or glucose. • The production of glucose in plants is known as photosynthesis. • Cellular Respiration occurs when bacteria, plant, fungi, and animal cells convert glucose to make energy. • Glucose- the simplest form of sugar, used as a source of energy . • First stage of cellular respiration takes place in the cytoplasm. • Cytoplasm- the jelly like substance of a cell. • The second and third stage require oxygen the first stage doesn't.

  6. Fermentation pg.6 • When oxygen is not available cellular respiration can not work. • So energy is formed through fermentation. • Fermentation-the process in which cells break down molecules without the use of oxygen. • There are two types of fermentation lactic acid fermentation and alcohol fermentation.

  7. Meiosis and Mitosis pg.7 • The three main stages of cell division is interphase, mitosis, and cytokinesis. • Mitosis has four stages prophase, metaphase, anaphase, and telophase. • Meiosis- the type of cell division that produces reproductive cells.

  8. Asexual Reproduction pg.8 • There are four types of asexual reproduction binary fission, spores, budding, and vegetative reproduction. • Binary fission-a type of asexual reproduction in which a cell divides into two parts. • Budding- a type of asexual reproduction that involves the outgrowth of a small part of the parent and develops into a new organism. • Spores- a type of asexual reproduction when spores reproduce on there own. • Vegetative reproduction-a type of asexual reproduction found in plants when a growth from the parent plant eventually becomes a new plant.
