31
In most cases, which tissue layer(s) of a leaf contains chloroplasts?
mesophyll
32
Accuracy - bow and arrow
in the center
33
Precision
the arrows are bunched up but not in center
34
Vascular
Composed of veins in the plant - Xylem - phloem
35
Ground
Everything in between dermal and vascular storage cells
36
Dermal
Covers the plant - waxy coating - leafy hairs (trichomes) - secretory glands - epidermis periderm
37
Function of vascular
Maintaining the water balance and sugar balance of a plant | - transportation
38
Function of ground
- photosynthesis - storage - support - regeneration
39
Function of dermal
- protection | - prevention of water loss
40
percent error
Percent errors tells you how big your errors are when you measure something in an experiment.
41
percent difference
Percent difference is practically the same as percent error, only instead of one “true” value and one “experimental” value, you compare two experimental values.
42
What is important to consider when performing DNA barcoding?
contamination
43
Morphology
The study of the form, structure and configuration of an organism.
44
Taxonomy
a branch of science that describes, names, and classifies.
45
What organisms perform photosynthesis
plants, some bacteria, some protists
46
photosynthesis equation
water + Co2 --> oxygen + sugars
47
Homebox genes
These genes are recognized by a conserved sequence found in plants, fungi, protists, and animals. Homeobox genes contain the homeodomain, which is consistently around 180 nucleotide base pairs in length. T
48
Many gene sequences that are involved in gene regulation contain a conserved sequence. This means that
the same DNA sequence can be found in a wide variety of organisms.
49
Which of the following do you predict would occur if RCO was over expressed in the margins of Arabidopsis leaves?
a compound leaf would form
50
Transcription factors regulate gene expression by
binding to a specific location on the DNA.
51
During leaf development, the meristem tissue divides __, producing one daughter cell that is just like the mother and another cell that differentiates into guard cell precursors.
Asymmetrically
52
which plants (in general) should have fewer stomata?
desert plants
53
standard error of the mean (SE)
The SE represents the standard deviation of the means of many trials. If you were performing an experiment by sampling a population over and over, you would report the SE.
54
How to estimate SE
SE can be estimated by calculating the standard deviation and dividing by the square root of the sample size.
55
Transcription factor SPEECHLESS
responsible for promoting mother cell to the guard cell lineage basic-helix-loop-helix or bHLH
56
Transcription factor MUTE
promotes guard cell development | basic-helix-loop-helix or bHLH
57
Transcription Factor FAMA
prevents the guard cells from de-differentiating or forming more than 2 guard cells at a time basic-helix-loop-helix or bHLH
58
Transcription Factors Scream 1 and 2
considered co-transcription factors since both are required.
59
Trees? According to this class
a woody plant characterized by a single dominant stem called a trunk
60
metacognition
awareness and understanding of one's own thought processes.
61
Growth vs Fixed Mindset?
In a fixed mindset students believe their basic abilities, their intelligence, their talents, are just fixed traits. ... In a growth mindset students understand that their talents and abilities can be developed through effort, good teaching and persistence.
62
Planning
identifying goals and strategies
63
Monitoring
keeping track of your progress toward the goals
64
Evaluating
continually assessing the solutions and evaluating your strategies.
65
stomata
pores in a leaf - exchange of gas - flow of water/water absorption regulating water movement through transpiration
66
Arapadisis
- usefulness for genetic experiments - short generation time - small size that limited the requirement for growth facilities - seed production through self pollination
67
Compound vs dissecting
- dissecting microscopes are for viewing the surface features of a specimen - compound microscopes are designed to look through a specimen.
68
Meristem
region of cells capable of division and growth in plants
