Cell Membrane and Cell Transport

Master cell membrane structure and transport! Learn about osmosis, diffusion, and active transport.

Inside the Cell Membrane with the Amoeba Sisters Watch the video to help review the cell membrane before answering the following questions. Parts of the Cell Membrane Match the part of the cell membrane with their function Transport Protein A type of transport protein in the membrane whose role is to help large molecules get through the cell membrane. Phospholipid Specialized lipid made of a phosphate (polar), head and two fatty acid (nonpolar) tail. Phosphate head Hydrophilic, polar part of a phospholipid Fatty Acid Tails Hydrophobic, nonpolar part of a phospholipid Semipermeable Allows some substances to pass across it and not others. Cholesterol Molecule used to strengthen the cell membrane. Carbohydrates Molecules used to identify a cell. Cell Transport with the Amoeba Sisters Watch the video to review before answering the following questions. Passive vs. Active Transport Place the following into either active or passive transport. Passive Transport Does not require energy Goes with the concentration gradient Molecules move from high to low concentrations Active Transport Does require energy Moves against the concentration gradient Molecules move from a low area of concentration to a high area of concentration Type of Transport Place each type of transport in either passive or active transport. Passive Transport Osmosis Diffusion Facilitated Diffusion Active Transport Protein pumps Exocytosis Endocytosis Phagocytosis In this image, the first beaker shows what type of solution? Hypertonic Hypotonic Isotonic In the previous question, which way would water move in this solution? Into the cell Out of the cell Water would move equally both ways In this image, the second beaker shows what type of solution? Hypertonic Hypotonic Isotonic In the previous question, which way would water move in this solution? Into the cell Out of the cell Water would move equally both ways In this image, the third beaker shows what type of solution? Hypertonic Hypotonic Isotonic In the previous question, which way would water move in this solution? Into the cell Out of the cell Water would moe equally both ways For each image of red blood cells below, enter what type of solution the cells are in (hypertonic, hypotonic, or isotonic), Make sure you type your answers in lowercase. hypertonic isotonic hypotonic
