Sequencing ,[object Object],Discovering Cells Hooke sees cells in cork. Leeuwenhoek sees many one-celled organisms. Schleiden concludes that all plants are made of cells. Schwann concludes that all animals (and all living things) are made of cells. Virchow proposes that new cells form only from cells that already exist. - Discovering Cells

Building Vocabulary ,[object Object],Key Terms: Examples: - The Cell in Its Environment selectively permeable The cell membrane is selectively permeable , which means that some substances can pass through the membrane while others cannot. diffusion Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. osmosis Osmosis is the diffusion of water molecules through a selectively permeable membrane. The movement of dissolved materials through a cell membrane without using cellular energy is called passive transport . Active transport is the movement of materials through a cell membrane using cellular energy. Key Terms: Examples: passive transport active transport
