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.
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.
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.
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.
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.
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.
