Describe the 3 principles of the cell theory
All organism’s consist of one or more cells The cell is the basic structure for all organisms All cells come from other cells
Describe the similarities and differences of prokaryotic and eukaryotic cells. Give an example of each
Eukaryotic cells have a nucleus and prokaryotic does not. They both have vessels and vacuoles E- animals and plants P- bacteria
Compare and contrast animal cells
Similarities- cell membrane, er, Golgi apparatus, cytoplasm, ribosomes, lysosomes, nuclei Differences- plant has a cell wall, plant has chloroplast, animal cells have no cell wall
Identify cell membrane
Membrane that separates the cell from the outside environment
Cell wall
Tough, outside part of the cell
Cytoplasm
The material within a living cell
Cytoskeleton
A microscopic network of protein filament
Nucleus
The control center of a cell
Er rough and smooth
The endoplasmic reticulum is like a cellular highway, where proteins are transported from one part to the other. Ribosomes on the ER also help in protein synthesis.
Golgi apparatus
It is a special organell found in the sytoplasm of the eukaryotic cell, it functions in the modification of proteins after they are synthesized
Vacuole
A vacuole has a primarily function of wastage removal from the plants body.
Lysosomes
lysosomes digests and recycles used cell components
Ribosomes
It synthesizes proteins
Mitochondria
It is where the energy is made
Diffusion
When something moves from a higer concentration to a lower concentration
osmosis
The tendency of molecules of a solvent to pass through a semipermeable membrane from a less concentrated solution into a more concentrated solution
facilitated diffusion
Facilitated diffusion is when a molecule cannot just passively diffuse across a membrane; however, it requires a protein “carrier” and energy in the form of ATP to move across the membrane.
Active Transport
The movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
What happens when cell molecules reach dynamic equilibrium?
the molecules continue to move across the cell membrane; nothing changes, nothing stops
What factors affect the rate if photosynthesis
Temperature, amount of water, and amount of sunlight
What is cellular respiration
A process were cells harvest the energy stored in food
What is the formula for cellular respiration
C6H12O6+O2 —–> CO2+H2O+Energy
How many ATP is formed during cellular respiration?
38 ATP
What is Aerobic and Anaerobic
Aerobic requires energy and anaerobic does not
