creates energy in the form of ATP
Involved in asexual reproduction.
Mitosis
What is homeostasis?
The tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes
What is the only mammal capable of true flight?

Ribosomes' job
Build Proteins
What are the four stages of mitosis?
Prophase, Metaphase, Anaphase, Telophase
How does your body maintain homeostasis?
Breathing to expel CO2 and inhale O2
Peeing to control pH
Insulin release after eating
What is the fastest known flying bird?

Serves as a highway (transportation system).
Rough ER houses ribosomes
What occurs during each stage of mitosis?
Prophase: Nuclear membrane disappears, spindle forms
Metaphase: Chromosomes line up at equator
Anaphase:Sister chromatids divide and spindle pulls to opposite ends
Telophase: Nuclear membrane reappears, spindle disappears
What is osmosis?
Movement of water through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane

How does meiosis produce genetically different organisms?
1. Crossing Over
2. Homologous Chromosomes part ways to create haploid cell
What is diffusion?

Photosynthesis reactants and products.
Reactants: Carbon Dioxide, Water, Sunlight
Products: Glucose, Oxygen
How do cells "born" of mitosis differ than those of meiosis?
Mitosis: diploid, genetically identical to parent cell
Meiosis: haploid, creates genetically different cell from parent
