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.
