QuestionAnswer
Units of the Metric System (Length, width, height) Kilometer (1km=1000m), meter, centimeter, millimeter, micrometer(1000 micro meters=1mm).
Units of the Metric System (Mass) Metric ton (1t=1000kg, kilogram, gram, milligram, microgram (1000 micro grams=1mg).
Units of the Metric System (Volume) liter, milliliter (1000ml=1L), cubic centimeter, microliter (1000 micro liters=1ml).
Scientific Method Observation Question Hypothesis Prediction Experiment Conclusion.
Sample Size The number of samples you can use in an experiment.
Totipotency The ability of cells to undergo cell division and differentiate to regenerate.
Micropropagation A technique used to asexually generate new plants by culturing plant cells and tissue in vitro.
Micropropagation Steps 1. Tissue prep 2. Transfer to sterile media 3. Multiplication (shoot and root) 4. Transfer to soil 5. Acclamation
Plant Protective Structures Raphides and Druce Crystals
Scientific Writing Title Abstract Introduction Materials and Methods Results Discussion References
Shapes and Arrangements of Bacteria Cocci(balls grouped together), Baccilli (chain-like pills), Spirilli (Spiral), Vibrios (pear-like), Filamento (stick-like).
Independent Variable The factor that is changed or manipulated by the experiment.
Dependent Variable The factor that is observed/measured.
Controlled Variable Remains constant for all groups.
Continuous Variable Uses a logical set of numbers.
Discrete Variable Uses an unordered set of numbers.
Gametic Cell vs. Somatic Cell Gamete-reproductive cell that has half the copies for each gene. Somatic Cell-Form the body, organs of the organism.
4 Phases of Mitosis Prophase-condensing of chromosomes. Metaphase-sister chromatids line up. Anaphase-sister chromatids divide. Telophase-chromosomes are at poles and expanding.
Phases of Meiosis Prophase I, Metaphase I, Anaphase I, Telophase I. (sister chromatids cross over)
Differences Between Mitosis and Meiosis Meiosis has crossing over and independent assortment of homologous pairs (these increase genetic diversity).
