Term Definition
Osmosis A process that releases energy
Carbohydrates Carbohydrates are ugar, starch, and cellulose.They provide cells with energy and structural support.
Lipids Lipids are ats, oils, and waxes. Lipids can't mix with water. Lipids provide the cell with energy.
Proteins Proteins are made of smaller molecules-amino acids. Proteins control chemical reactions, support repair and growth of tissue, allow movement, fight infection, and deliver oxygen.
What happens when chemicals join amino acids? Proteins are formed
Why is water important to a cell? Many of the chemical reactions in a cell take place in water.
Diffusion Diffusion occurs when molecules spread out until they are evenly mixed.
Exocytosis Molecules move out of the cell
Endocytosis Molecules move into the cell
How does cell size affect the transport of materials into a cell? It takes a longer period of time for materials to move into a large cell
The process that uses energy to transport materials across the cell membrane Active transport
What process produces energy without oxygen? Fermentation
Which process releases energy? Cellular respiration
Are cells alive? Yes
Are atoms and molecules alive? No
Do cells grow and reproduce? Yes
What is the smallest possible living thing? A cell
What is the smallest unit of an element? Atom
Passive Transport Molecules diffuse through a membrane
Active Transport Cell use chemical energy
