What is the function of the golgi complex? Final Packaging center for proteins to be shipped out of the cell
What is the function of the central vacuole? Used to store, water, minerals, and space
What is the function of the vesicles? Membrane bound sacs used for storage
What is the function of the lysosome? Membrane bound sac that contains digestive enzymes
What is the function of the cell wall? Provides protection and support for plant cells
What is the function of the cytoskeletal fibers? Provides support, movement, and aids in transporting material around the cell
What is the function of the chloroplasts? Cytophotosynthesis
What is the function of the mitochondria? Power house of the cell
Name and describe three types of chemical bonds? Ionic: given or taken Covalent: electrons are shared Hydrogen: weak bond
What are the four types of biomolecules and what are the subunits of each? Lipids->fatty acids Proteins->amino acids Carbohydrates->monosaccharides Nucleic acids->nucleotides
Is diffusion passive or active? Passive
Is osmosis passive or active? Passive (water)
Is facilitated diffusion passive or active? Passive (polar molecules to enter or out without energy)
What is a sodium potassium pump? Pumps sodium ions out and potassium ions in uses ATP
What is endocytosis? The movement of a substance into a cell by forming a vesicle
What is exocytosis? The movement of a substance out of a cell using a vesicle
What is photosynthesis? To convert solar energy to chemical energy
What is mitosis? Division of the cell
What is a master gene? The main gene that control of direct a group of other genes
What is the function of proteins? They build things and do jobs in our bodies
What is the function carbohydrates? Main source of energy
What is the function lipids? They make cell membranes
What is the function of nucleic acids? Instructions that make all activities possible
What happens during G1? Checks the size and development before copying DNA
What happens during G2? DNA is checked for copying mistakes
What happens during M? Spindle fiber attachment is checked
What happens in Interphase during G1? Growth and metabolic activity
What happens in Interphase during S? DNA is copied
What happens in Interphase during G2? Cell grows and prepares mitosis
What happens in Prophase? Chromosomes become visible Nuclear envelop dissolves Spindle forms
What happens in Metaphase? Chromosomes line up along equator
What happens in Anaphase? Centromeres divide Chromosomes move toward opposite poles
What happens in Telophase? Nuclear envelope forms at each pole Chromosomes uncoil Spindle dissolves Cytokinesis begins
What happens in Protein Synthesis during Replication? Copying of DNA
What happens in Protein Synthesis during Transcription? DNA to RNA

Where do light reactions occur? Thylakoid discs
Where do dark reactions occur? Stroma
Where does glycolysis occur? Cytosol
Where does the Kreb's Cycle occur? Mitochondria
What is meiosis? It is the process of creating gametes To reduce the number of chromosomes in each of the four nuclei by half
What factors of gene expression explain how organisms with similar DNA can look very different? How genes are expressed When the genes are decoded How long a particular gene is active
What percent of genetic similarity do we have with chimpanzees? 98 Percent

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
