UofA - Bio 108 Lab Exam Questions With
Correct Answers
Aseptic Technique - CORRECT ANSWER✔✔-Method designed to prevent
| | | | | | |
contamination from microorganisms.
| | |
Arabidopsis thaliana - CORRECT ANSWER✔✔-In lab we tested the
| | | | | | | | |
affects of phosphate on this organism. It is small, requires little space,
| | | | | | | | | | | |
and is easy to grow.
| | | |
Ceratopteris sp. - CORRECT ANSWER✔✔-A homosporous fern with two
| | | | | | | | |
distinct phases to its life cycle. Has a simple haploid gametophyte and
| | | | | | | | | | | |
complex diploid sporophyte. Its spores germinated into gametophytes.
| | | | | | |
Compound Microscope - CORRECT ANSWER✔✔-3 lens
| | | | | |
systems(condenser, objective, ocular). | |
Calculate magnification of drawing - CORRECT ANSWER✔✔-size of
| | | | | | | |
drawing(ruler) / size of object(epu) | | | |
,Dichotomous key - CORRECT ANSWER✔✔-A dichotomous key is a tool
| | | | | | | | | |
that allows the user to determine the identity of items in the natural
| | | | | | | | | | | | |
world, such as trees, wildflowers, mammals, reptiles, rocks, etc.
| | | | | | | |
Dissecting Microscope - CORRECT ANSWER✔✔-Two eyepieces and two
| | | | | | | |
objectives. Provides a 3 dimensional view. Lower magnification level
| | | | | | | | |
compared to a compound microscope. | | | |
Species - CORRECT ANSWER✔✔-Group of organisms capable of
| | | | | | | |
interbreeding
Speciation - CORRECT ANSWER✔✔-Event which produces two or more
| | | | | | | | |
separate species from one lineage. | | | |
The 4 mechanisms of evolution - CORRECT ANSWER✔✔-Mutation, gene
| | | | | | | |
flow, genetic drift, and natural selection.
| | | | | |
Internal node - CORRECT ANSWER✔✔-Point in a phylogenetic tree were
| | | | | | | | |
|a branch splits up
| | |
Terminal node - CORRECT ANSWER✔✔-End of the branch
| | | | | | |
Single-base substitution - CORRECT ANSWER✔✔-When one nucleotide
| | | | | | |
base replaces another
| |
,Molecular clock - CORRECT ANSWER✔✔-The number of differences
| | | | | | | |
between species can reveal the mutation rate.
| | | | | |
Plant systems for acquiring resources - CORRECT ANSWER✔✔-
| | | | | | |
Root(water and nutrients) and shoot(Co2 and light) systems. Shoot
| | | | | | | | |
system is everything above ground.
| | | |
Vascular tissue - CORRECT ANSWER✔✔-Complex conducting tissue
| | | | | | |
which runs throughout the entire plant, formed of more than one cell
| | | | | | | | | | | |
type, found in vascular plants. The primary components are xylem and
| | | | | | | | | | |
phloem.
Function of xylem and phloem - CORRECT ANSWER✔✔-Transport fluid
| | | | | | | | |
and nutrients internally.
| |
Xylem: Transport water up
| | |
Phloem: transport sugars from photosynthesis down
| | | | |
Dermal tissue - CORRECT ANSWER✔✔-outer layer of cells covering
| | | | | | | | |
plant. Composed of epidermis and the cuticle. May also have
| | | | | | | | | |
trichomes(small hairs) |
, Ground tissue - CORRECT ANSWER✔✔-Fills space between epidermis
| | | | | | | |
and vascular tissue. May contain specialized cells for support, storage,
| | | | | | | | | |
protection, or photosynthesis. | |
Helianthus sp. - CORRECT ANSWER✔✔-A sunflower seedling
| | | | | |
Petiole - CORRECT ANSWER✔✔-Attaches blade of lead to the stem.
| | | | | | | | | |
Point of attachment called node.
| | | |
Patterns of leaf arrangement. - CORRECT ANSWER✔✔-Alternate(spiral)
| | | | | |
Opposite(pairs)
Whorled(3 or more at same node) | | | | |
Types of leafs - CORRECT ANSWER✔✔-Simple(single leaf)
| | | | | |
Compound(divided into leaflets) | |
Root systems - CORRECT ANSWER✔✔-Radicle/primary( main root sent
| | | | | | | |
into ground from which lateral roots branch off)
| | | | | | |
