Science Chapter 2 Vocab Quiz

a series of chemical reactions that convert light energy, water, and carbon dioxide into the food-energy molecule glucose and give off oxygen

• diffusion
• organelle
• photosynthesis
• cell membrane

the theory that states that all living things are made of one or more cells, the cell is the smallest unit of life, and all new cells come from preexisting cells

• cell theory
• cytoplasm
• cell respiration
• osmosis

a membrane-bound organelle that uses light energy and makes food - a sugar called glucose - from water and carbon dioxide in a process known as photosynthesis

• organelle
• chloroplast
• cytoplasm
• diffusion

the diffusion of water molecules only through a membrane

• cell theory
• cell wall
• nucleus
• osmosis

a flexible covering that protects the inside of a cell from the environment outside the cell
