Study Notes
Cell Types
- Prokaryotic cells are simple, lack a nucleus and membrane-bound organelles.
- Eukaryotic cells are more complex, containing a nucleus and various membrane-bound organelles.
Nucleus and Related Structures
- Nucleus serves as the control center of the cell, housing DNA.
- Nucleolus is the site where ribosome assembly begins.
- Nuclear membrane separates nuclear contents from the cytoplasm and regulates material passage.
Protein Synthesis
- Ribosomes are the sites of protein assembly, utilizing DNA instructions.
- Endoplasmic Reticulum (ER) consists of:
- Rough ER involved in protein assembly and transport.
- Smooth ER responsible for lipid assembly and transport.
Golgi Apparatus
- Golgi Body modifies, sorts, and packages proteins from the ER for storage or transport outside the cell.
Energy Conversion Organelles
- Chloroplasts carry out photosynthesis, converting light energy into chemical energy.
- Mitochondria are the powerhouses of the cell, performing cellular respiration to produce ATP from food-derived chemical energy.
Cell Structure
- Cell wall provides structural support, protection, and shape to the cell, mainly found in plant cells.
- Cell membrane acts as a selective barrier, regulating the entry and exit of substances.
Movement Structures
- Cilia are short, hair-like projections that facilitate movement.
- Flagella are longer, whiplike projections used for motility.
