1
Cell
The smallest unit of life.
New cards
2
Microscope
An instrument used to study cells that cannot be seen with the naked eye.
New cards
3
Unified Cell Theory
States that all organisms are made of one or more cells, the cell is the basic unit of life, and new cells arise from existing cells.
New cards
4
Prokaryotes
Single-celled organisms of the domains Bacteria and Archaea.
New cards
5
Peptidoglycan
The primary component of most prokaryotic cell walls.
New cards
6
Plasma Membrane
A lipid bilayer that surrounds the cell, regulating what enters and exits.
New cards
7
Eukaryotic Cell
A type of cell that is typically larger than prokaryotic cells and has a true nucleus and membrane-bound organelles.
New cards
8
Nucleus
The membrane-bound organelle that contains the cell's DNA.
New cards
9
Ribosomes
Cellular structures that perform protein synthesis.
New cards
10
Mitochondria
Organelles that participate in cellular respiration and produce ATP.
New cards
11
Peroxisomes
Organelles that hydrolyze fatty acids, amino acids, and some toxins.
New cards
12
Vesicles
Small membrane-bound compartments for storage and transport within the cell.
New cards
13
Lysosomes
Digestive organelles in animal cells that break down macromolecules.
New cards
14
Chloroplasts
Organelles where photosynthesis takes place in plant cells.
New cards
15
Golgi Apparatus
Cellular component that modifies, packages, tags, and transports proteins and lipids.
New cards
16
Endomembrane System
A system that includes the nuclear envelope, lysosomes, vesicles, ER, Golgi apparatus, and plasma membrane.
New cards
17
Cytoskeleton
A network of protein elements that provide structure and shape, and facilitate movement within the cell.
New cards
18
Microfilaments
The narrowest type of protein element in the cytoskeleton, associated with myosin.
New cards
19
Desmosomes
Cell structures that act like spot welds, anchoring cells together.
New cards
20
Tight Junctions
Watertight seals between adjacent cells.
New cards
21
Plasmodesmata
Channels that connect adjacent plant cells and facilitate communication.
New cards
22
Gap Junctions
Channels that connect adjacent animal cells, allowing for communication.
New cards
23
Central Vacuole
A large storage compartment in plant cells that can expand without producing more cytoplasm.
