CellULAR transport AD2023

Master cellular transport! Plasma membrane, passive/active transport, osmosis, diffusion, and bulk transport questions.

The plasma membrane Parts of the membrane Instructions: Write the correct word according to the part of the membrane (copy and paste the answer or write it correctly) Word Name Word Name C Hydrophilic head D Hydrophobic tails E Phospholipid A Integral proteins B Cholesterol F Carbohydrate G Lipid bilayer - - Instructions: Select the correct word using the word bank. - Passive transport is the one in which the movement of particles occurs from a high concentration area to an area of low concentration. The molecules go “down” their concentration gradient.- Active transport is the one in which the movement of particles occurs from a low concentration area to an area of high concentration. This transport requires energy.- The hydrophilic part of the phospholipids is oriented in or out of the cell and the hydrophobic region is conformed by tails facing each other to form the double layer.- The carbohydrate is a molecule that helps the cell to perceive signals from the outside.- In diffusion, there is the movement of solute particles, while in osmosis there is the movement of solvent particles.- Cholesterol is the molecule that gives stability to the cell membrane.- Integral proteins help molecules cross the membrane more easily.- The cell membrane is made up of two layers of a molecule called aphospholipid. Osmosis Difussion Match the columns Hypotonic solution Water enters the cell Hypertonic solution Water leaves the cell Isotonic solution Water enters and leaves the cell in a balanced way Facilitated diffusion Solute molecules pass through the membrane by integral protein. Facilitated osmosis SOLVENT molecules cross the membrane by integral protein. Simple diffusion The solute passes through the lipid bilayer Simple osmosis Water passes through the lipid bilayer Endocytosis Instructions: Select the correct answer to complete the table Exocytosis Phagocytosis Pinocytosis Structure generated by the membrane: Evagination Invagination Molecules encapsulated: Large substances Small substances The cell is said to be: Eating Drinking Instructions: Write the correct answers 1. Active transport is also known as vesicular transport.2. Exocytosis is the process in which materials are expelled from the cell.3. The organelle called the Golgi apparatus is the one that forms the vesicles that fuse with the membrane during exocytosis.4. The process in which molecules are introduced into the cell is known as endocytosis. Image B What process is exemplified in the number 2? Pinocytosis Phagocytosis Osmosis Diffusion Vesicles during endocytosis are formed by... Golgi apparatus Ribosomes Cell membrane 4
