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.
