Membranes
The main structural component of the cell membrane is what molecule?
Phospholipid
This structure is found on the Endoplasmic Reticulum and is used to make proteins.
Ribosome
A large, central compartment that holds water and other molecules.
Central vacuole
When a solute moves down its' concentration gradient without the aid of energy, it is called ______________.
Passive Transport
What type of cell has no nucleus?
Prokaryotic
Name 1 of the two things that help keep the cell membrane fluid.
Cholesterol, Unsaturated Fatty Acids
This structure creates transport vesicles and is used to process proteins as they move to their final destination.
Golgi
An organelle with a double membrane and is where photosynthesis occurs.
Chloroplast
This type of transport moves molecules against their concentration gradient.
Active
The cell membrane does not let everything cross. This feature is referred to as _________________.
Selective Permeability
Phagocytosis is an example of what type of transport mechanism?
endocytosis
This structure contains a matrix, an inner and outer membrane, and is involved in the process of cellular respiration.
Mitochondria
This structure is made out of cellulose and provides strength to the cell.
Cell Wall (plant)
In osmosis, water moves from an area of _______ water concentration to an area of ________ water concentration.
High / Low
These proteins have short sugar chains attached and are used for cell identification.
Cell Recognition Proteins
What type of molecule can diffuse directly across the cell membrane?
Small and Non-Polar
This is found inside the nucleus and is used to make ribosomes.
Nucleolus
What is one organelle/structure and animal cell has that a plant cell does not?
lysosome, centriole/centrosome
When there is an equal concentration of solutes inside and outside of the cell, the solution outside of the cell is considered to be ________.
Isotonic
Facilitated transport is used for molecules that cannot directly diffuse through the cell membrane. Give an example of what type of molecule would use this transport mechanism.
Sugars, Amino Acids, Water, Small charged molecules, Ions...
These proteins allow ions to pass through the cell membrane.
Channel / Carrier Proteins
This structure is full of enzymes and is where the breakdown of large molecules occurs in the cell.
Lysosome
These channels allow plant cells to "talk" to one another and are similar to Gap Junctions in animal cells.
Plasmodesmata
Plant cells prefer to be in a state of turgor pressure, which occurs when the solution outside of plant cell is _____________.
Hypotonic
This type of cytoskeleton filament is found in cilia and flagella.
Microtubules
