Study Notes
Key Cell Components
-
Cell Membrane
- Semipermeable barrier controlling entry and exit of substances
- Composed of phospholipid bilayer
-
Smooth Endoplasmic Reticulum (SER)
- Synthesizes lipids for cell membrane
- Detoxifies harmful metabolic byproducts
-
Rough Endoplasmic Reticulum (RER)
- Studded with ribosomes for protein synthesis and modification
-
Golgi Apparatus
- Processes, sorts, and packages proteins for secretion
- Involved in the cell’s export activities
-
Lysosome
- Contains digestive enzymes to break down large macromolecules
- Plays a key role in waste disposal and recycling
-
Microtubule
- Essential part of the cytoskeleton providing structural support
- Helps in cell shape maintenance and intracellular transport
-
Mitochondria
- Known as the powerhouse of the cell
- Converts glucose into ATP (adenosine triphosphate) for energy
-
Nucleus
- Central organelle housing genetic material (DNA)
- Regulates cellular activities such as growth and reproduction
-
Ribosome
- Site of protein synthesis
- Can be found floating freely in the cytoplasm or attached to the RER
-
Nucleolus
- Located within the nucleus, responsible for ribosome production
- A dense region crucial for ribosomal RNA synthesis
-
Cytoplasm
- Gel-like substance filling the cell, allowing organelles to remain in place
- Medium for biochemical reactions and cellular processes
-
Large Central Vacuole
- Storage center for water, salts, nutrients, and proteins
- Maintains cell turgor pressure in plant cells
-
Cell Wall
- Rigidity and strength, providing structural support to the plant cell
- Located outside the cell membrane, composed mainly of cellulose
-
Chloroplast
- Organelles that perform photosynthesis, converting light energy into chemical energy
- Contains chlorophyll, the pigment responsible for green color and light absorption
