Question

complete the following table, listing the cell organelles function and indicating what type of cell each organelle can be found in (write yes or no). a comparison of cells organelle function prokaryotic cells eukaryotic cells animal cells plant cells cell wall plasma membrane cytoplasm nucleus ribosome

Explanation:

Brief Explanations
  • Cell wall:
  • Function: Provides structural support and protection to the cell.
  • Prokaryotic cells: Many prokaryotes (like bacteria) have a cell wall.
  • Animal cells: Do not have a cell wall as they rely on other mechanisms for support (e.g., cytoskeleton).
  • Plant cells: Have a rigid cell wall made of cellulose which helps maintain shape and protects the cell.
  • Plasma membrane:
  • Function: Controls the movement of substances in and out of the cell (selective permeability).
  • Prokaryotic cells: Present as the outermost layer (in some cases with a cell wall outside it).
  • Animal cells: Present as the boundary of the cell.
  • Plant cells: Present just inside the cell wall.
  • Cytoplasm:
  • Function: Holds organelles and is the site of many metabolic reactions.
  • Prokaryotic cells: Fills the cell interior.
  • Animal cells: Fills the cell interior.
  • Plant cells: Fills the cell interior.
  • Nucleus:
  • Function: Stores genetic material (DNA) and controls cellular activities (e.g., transcription).
  • Prokaryotic cells: Do not have a true nucleus (DNA is in the nucleoid region).
  • Animal cells: Have a well - defined nucleus.
  • Plant cells: Have a well - defined nucleus.
  • Ribosome:
  • Function: Site of protein synthesis.
  • Prokaryotic cells: Present (smaller 70S ribosomes).
  • Animal cells: Present (larger 80S ribosomes).
  • Plant cells: Present (larger 80S ribosomes).
