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.
