Cell Organelles
This organelle contains DNA and controls cell activities.
Nucleus
These macromolecules synthesize proteins and may be attached to the rough ER.
Ribosomes
The cell membrane is primarily made of this double layer.
Phospholipids
Movement of molecules from high concentration to low concentration.
Diffusion
A solution with equal solute concentration inside and outside the cell.
Isotonic
This organelle modifies and packages proteins for transport.
Golgi Apparatus
This network of membranes is responsible for lipid production.
Smooth Endoplasmic Reticullum
The polar region of phospholipids that faces water.
Hydrophilic head
Diffusion that occurs through membrane proteins.
Facilitated Diffusion
A solution that causes a cell to swell.
Hypotonic
This organelle produces ATP through cellular respiration.
Mitochondrion
This organelle stores water and helps maintain turgor pressure in plant cells.
Central Vacuole
These membrane components help maintain membrane fluidity.
Cholesterol
Movement of water across a selectively permeable membrane.
Osmosis
A solution that causes a cell to shrink.
Hypertonic
This structure provides rigid support for plant cells.
Cell wall
These structures help cells move or move substances across the cell surface.
cilia or flagella
This model describes the membrane as a flexible structure with many embedded proteins.
Fluid mosaic-model
Transport that requires ATP energy.
Active transport
When a red blood cell bursts due to water entering the cell.
Cytolysis
This organelle contains digestive enzymes that break down waste and damaged cell parts.
Lysosomes
This structure maintains cell shape and allows intracellular movement.
Cytoskeleton
These membrane structures allow specific substances to cross the membrane.
Transport proteins
The protein pump that moves sodium out of the cell and potassium into the cell.
When plant cells lose water and the membrane pulls away from the cell wall.
