Cell Theory/Photosynthesis/Cellular Respiration 5.1-6.5 Flashcards
(48 cards)
Hydrophilic
Water loving
Prokaryotic cell
Cells with no nucl us and are missing other organelles
Eukaryotic cell
Have nucleus and most organelles
Animal Cell
No cell wall no chloroplast, vacuoles are small or none
Cell wall
Outer structure made of cellulose that provides structure
Chloroplast
Contain the green pigment chlorophyll and perform photosynthesis
Vacuoles
Organelle that provide extra water storage and pressure
Plastids
Organelles that hold different color pigments in things such as flower or fruit
Cell membrane is semi permeable what does this mean?
It means that it only allows certain molecules to pass through
Diffusion
The net movement or molecules from an area of high concentration to an area of low concentration
Concentration Gradient
The difference between the concentration of a particular molecule in one area and the concentration in an adjacent area
Osmosis
The diffusion of water across a semi permeable membrane
Hypertonic Solution
The concentration of solutes is higher than the concentration of solutes inside the cell
Hypotonic
The concentration of solutes is lower than the concentration of solutes inside the cell
Isotonic
The concentration of solutes equals the concentration of solutes inside the cell
Facilitated Diffusion
Use of carrier proteins for diffusion
Active Transport
When energy is used to transport molecules across the membrane
Bulk transport
Large molecules food and other substances are packaged in membrane band sacs and moved across the membrane
Endocytosis
Cell membrane folds into a pouch that encloses the particles
Pinocytosis
Cell membrane encloses a droplet of fluid and brings it to the cell
Phagocytosis
Cell membrane encloses food particles and brings it to the cell
Exocytosis
Waste and cell products leave the cell
Energy
The ability to do work
Work
The ability to cause a change in other matter
