QuestionAnswer
Hypotonic When the % of water is higher in the ECF then the cell
Hypertonic When the % of water is lower in the ECF then the cell
Isotonic When the % of water is equal in the ECF and the ICF
Plasmolysis Process of destroying a cell by excessive dehydration; cell will become droopy, and the contents dry out and kills the cell
Cytolysis Process of cells busting as a result of increased pressure in the cell
DNA Bases A&T, G&C
RNA Bases A&U, G&C
DNA One type
RNA 3 types; messenger, transport, ribosomal
Passive Transport High to low concentration
Diffusion Movement of particles from an area of high to low concentration
Osmosis Diffusion of water through membranes
Facilitated Diffusion Movement of particles from high to low concentration added by a protein within the Fluid Mosaic membrane
Active Transport Molecules are assisted from moving from low to high concentration
Endocytosis Taking in materials by vacuole formation
Pinocytosis (cell drinking) Formation of vacuoles as a result of liquid impinging on the cell membrane & forcing dents or channels into the cell (liquids)
Phagocytosis Formation of vacuoles as a result of a cell engulfing the particle (solids)
Exocytosis Elimination of materials from vacuoles
Secretion A squeezing action in the plasma membranes (liquid)
Egestion The pseudopods retreat or oral grooves open
Photosynthesis 6CO2 + 12H2O > C6H12O6 + 6O2 + 6H20
Cellular Respiration 6O2 + C6H12O6 > 6CO2 + 12H2O + 36ATP
Transcription In the nucleus, the DNA copies a code (into mRNA)
Translation In the cytoplasm, the rRNA, tRNA, and the mRNA make protein
Eukaryotic Cells A type of cell that has a true nucleus. Example: Protista, Fungi, Plantae, Animalia
Prokaryotic Cells A type of cell that doesn’t have a true nucleus. Example: Monera
Sporangia The reproductive structures in which spores are produced
Taxonomy The science of classifying organisms
Nephridia Open ended tubules that function in excretion
Clitellum Secretes a protective covering for eggs
Spores Reproductive cells that can produce a new organism without fertilization; haploid number of chromosomes
Shoot Tip Develops leaves and adjacent stem tissue
Epidermis Outer, protective, nonvascular layer of the skin of vertebrates
Blade The leaf
Petiole The stalk of the leaf
Withered Cotyledon The embryos of flowering plants
Ground Tissues Any tissue other than the epidermis and vascular tissues
Vascular Tissues Consists of xylem and phloem
Nodes A point on the stem where the leaf is attached
Internode The section between the 2 nodes
Axillary Bud Where the leaf petiole is attached to the stem
Xylem A vascular tissue in plants that carries water and dissolved materials up from the roots to the other plant parts
Phloem A vascular tissue that transports sugars, which were synthesized in the leaves, throughout the plant and down to the roots for storage
Guard Cells Occur in pairs around each stoma in the epidermis of a leaf; regulates the opening and closing of the stoma
Primary Succession Succession that begins without pre
Biotic Anything related to living things
Abiotic Anything related to nonliving things
Interspecific Competition Competition between two different species
Intraspecific Competition Competition between the same species
Non-Vascular Transport Elongated cells in the middle of their stocks
Chloroplasts Plastids that contain the green pigment chlorophyll and specialize in photosynthesis; located in the leaves

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.
