Questions and Answers

What role does the cell membrane play in relation to the cell?

  • It supports the cell structure independently of movement.
  • It allows the exchange of genetic material.
  • It provides energy for cellular activities.
  • It controls the movement of substances into and out of the cell. (correct)
  • Which statement accurately describes mitochondria?

  • They are primarily involved in protein synthesis.
  • They are visible with a light microscope in large numbers only in inactive cells.
  • They are involved in respiration and energy release. (correct)
  • Their structure is the primary site of photosynthesis.
  • What is the primary function of the cell wall in plant cells?

  • To determine the genetic characteristics of the plant.
  • To store nutrients and waste materials.
  • To provide shape and support while allowing substance permeability. (correct)

    Study Notes

    Cell Membrane

    • Forms a boundary between the cell's interior and its environment.
    • Regulates movement of substances in and out of the cell.

    Cytoplasm

    • Site of all cellular activities.
    • Contains organelles like mitochondria and ribosomes, as well as food reserves (glycogen, starch, oil droplets).
    • Appears granular in structure.

    Mitochondrion

    • Organelle where respiration occurs, providing energy for cellular functions.
    • Active cells, such as liver cells, have numerous mitochondria.
    • Structure is typically not clearly visible under light microscopy.

    Cell Wall

    • Nonliving layer external to the cell membrane in plant cells.
    • Permits free passage of liquids and dissolved substances.
    • Provides shape and structural support to plant cells.
    • Absent in animal cells.

    Vacuole

    • Mature plant cells contain a large central vacuole filled with cell sap (dilute solution of salts and sugars).
    • May also contain pigments.
    • Animal cells may have small, temporary vacuoles.

    Chloroplast

    • Organelle that contains the green pigment chlorophyll found in plant cells.
    • Abundant in palisade cells of leaves, where photosynthesis takes place.
    • Not present in animal cells.
