Study Notes
Cell Membrane
- Controls the entry and exit of substances in and out of the cell.
- Composed of a phospholipid bilayer featuring hydrophobic tails and hydrophilic heads.
- Present in both plant and animal cells.
Mitochondria
- Functions as the powerhouse of the cell, converting food into usable energy (ATP).
- Varies in quantity depending on cell type; muscle cells can contain thousands.
- Mitochondria are found in both plant and animal cells.
Nucleus
- Acts as the control center, regulating gene expression and DNA replication.
- Defined as a signature feature of eukaryotic cells, absent in prokaryotic cells.
- Surrounded by a protective membrane, prominently housed within plant and animal cells.
Cell Wall
- Provides structural support and protection; only present in plant cells.
- Composed of cellulose, contributing to cell shape and durability.
- Functions like a protective barrier similar to a storm shelter.
Vacuoles
- Serves as storage for nutrients, waste, and other materials.
- Primarily found in plant cells, also sequestering food and waste.
- Protects the cell from contamination by isolating waste products.
Chloroplasts
- Converts sunlight into chemical energy through photosynthesis.
- Contains chlorophyll, necessary for capturing light energy.
- Exclusively found in plant cells.
Cytoplasm
- The semi-fluid medium that fills the cell, facilitating the movement of materials.
- Contains dissolved molecules including enzymes, fatty acids, sugars, and amino acids.
- Found in both plant and animal cells, aids in cellular function and waste management.
Smooth Endoplasmic Reticulum
- Functions as a storage organelle important for lipid and steroid synthesis.
- Smooth in appearance compared to Rough ER due to lack of ribosomes.
- Present in both plant and animal cells, with higher concentrations in cells that release oils.
Rough Endoplasmic Reticulum
- Synthesizes and secretes proteins via ribosomes attached to its surface.
- Rough appearance is due to the presence of ribosomes, often associated with the nuclear envelope.
- Located in both plant and animal cells.
Golgi Apparatus
- Modifies, sorts, and packages proteins and lipids for secretion.
- Functions like a post office, packaging macromolecules for transport.
- Composed of stacks of membranes and found in both plant and animal cells.
Lysosomes
- Contains digestive enzymes to break down waste, bacteria, and cellular debris.
- Plays a role in cellular cleanup and recycling.
- Typically found in animal cells, functioning similarly to algae eaters in aquariums.
Nucleolus
- A round structure within the nucleus, involved in ribosome production.
- Can have multiple nucleoli within a nucleus, but human cells typically contain one.
- Found exclusively in eukaryotic animal cells.
