Study Notes
Cell Organelles
-
Nucleus: The cell's control center, housing DNA. It directs activities like growth, metabolism, and reproduction.
-
Cytoplasm: A jelly-like substance filling the cell. It holds the organelles and facilitates chemical reactions.
-
Cell Membrane: The cell's outer boundary. It regulates what enters and exits.
-
Cell Wall (Plant cells only): A rigid outer layer made of cellulose. It provides support and protection to plant cells.
-
Mitochondria: The "powerhouses" of the cell. They produce energy (ATP) through cellular respiration, using glucose.
-
Ribosomes: Protein factories. They build proteins crucial for cell function and growth. Found free in the cytoplasm or on the endoplasmic reticulum.
Specialized Organelles
-
Endoplasmic Reticulum (ER):
- Rough ER: Studded with ribosomes, it assists in protein production and transport.
- Smooth ER: Lacking ribosomes, it creates lipids and detoxifies harmful chemicals.
-
Golgi Apparatus (or Golgi Body): The cell's post office. It modifies, packages, and distributes proteins and other substances.
-
Lysosomes (Mostly Animal cells): Cell recycling centers. They contain enzymes to break down waste, damaged cell parts, and invaders.
-
Vacuoles: Storage sacs in the cell.
- Plant cells: Large vacuoles store water, nutrients, and waste.
- Animal cells: Smaller vacuoles store materials temporarily.
-
Chloroplasts (Plant cells only): The cell's solar panels. They utilize chlorophyll to carry out photosynthesis, converting light energy into glucose.
