Questions and Answers

Plasma membrane is said to be a selectively permeable membrane as it allows some substances to enter the cell, while prevents other substances. Due to this property, useful molecules of water, salt and oxygen enter the cell and ______ exits the cell

CO2

Plasma membrane is said to be a selectively permeable membrane as it allows some substances to enter the cell, while prevents other substances. Due to this property, useful molecules of water, salt and oxygen enter the cell and CO2 exits the cell. If any changes occur outside the cell, the cellular environment does not change due to plasma membrane. This condition is called ______

homeostasis

Endocytosis - To gulp/engulf food and other substances from outer environment. 2. Exocytosis - To excrete waste materials out of ______

cell

Diffusion - Entry or exit of small molecules like O2, CO2. Osmosis - The traveling of water from a part with more water to a part with less water through a selectively permeable membrane is osmosis. It is a physical process with 3 possibilities: hypertonic, isotonic, ______

Study Notes

Plasma Membrane

  • Plasma membrane is selectively permeable, allowing certain substances to enter the cell while preventing others.
  • Useful molecules like water, salt, and oxygen can enter the cell, while CO2 exits the cell.

Cellular Environment

  • Changes outside the cell do not affect the cellular environment due to the plasma membrane.
  • This condition is called homeostasis.

Cellular Processes

  • Endocytosis: the process of engulfing food and other substances from the outer environment into the cell.
  • Exocytosis: the process of excreting waste materials out of the cell.

Transport Mechanisms

  • Diffusion: the entry or exit of small molecules like O2, CO2, and others.
  • Osmosis: the movement of water from a part with more water to a part with less water through a selectively permeable membrane.
  • Osmosis has three possibilities: hypertonic, isotonic, and hypotonic.

Osmosis in Plants

  • Osmosis plays a crucial role in plant cells.
