CHAPTER 9 - HOMEOSTASIS AND PLASMA MEMBRANE VOCABULARY

A solution in cells in which dissolved materials and water occur in the concentration as inside the cell.

• Hypotonic Solution

• Isotonic Solution

• Vulpix

An active transport process by which large particles enter a cell.

• Osmosis

• Jigglypuff

• Endocytosis

In cells, solution in which the concentration of dissolved materials is higher in the solution surrounding the cell than the concentration inside the cell, which will shrink as water leaves the cell by osmosis.

• Hypertonic Solution

• Isotonic Solution

• Bulbasaur

The process resulting from a drop in turgor pressure as a result of water loss in a cell, causing the plasma membrane to shrink away from the cell wall.

• Plasmolysis

• Nidorina

• Exocytosis

A process requiring energy by which cells move materials against a concentration gradient.

• Passive Transport

• Active Transport

• Clefable

A passive transport of materials, such as sugars and amino acids, across the plasma membrane by way of transport proteins.

• Parasect

• Fluid Mosaic Model

• Facilitated Diffusion

An organelle of some protists such as Paramecium that collects excess water from the cell, then contracts and expels the water through a plasma membrane pore.

• Selectively Permeable

• Contractile Vacuole

• Venonat

The internal pressure of a cell due to water held there by osmosis pressure.

• Turgor Pressure

• Raichu

• Transport Proteins

In cells, solution in which the concentration of dissolved materials is lower in the solution surrounding the cell than the concentration inside the cell, which will swell and possibly burst as water enters the cell by osmosis.

• Hypertonic Solution

• Hypotonic Solution

• Pidgeotto

A net, random movement of particles from an area of higher concentration to an area of lower concentration, eventually resulting in even distribution.

• Diffusion

• Metapod

• Phospholipid
