BIOL 1104 Lecture Exam 2 Questions With Complete
Solutions
L10: 7 Properties that answer the question, "what is a
Metazoan?"
(Every Moment Of My Life My Rabbit Ate) Correct Answer 1.
Eukaryotes
2. Multicellular
3. Lack cell wall
4. Obtain energy by consuming other organisms
5. Reproduce sexually
6. Motile (some point of life)
7. Able to respond rapidly to external stimuli
L10: alternation of generations Correct Answer the alternation
between the haploid gametophyte and the diploid sporophyte in
a plant's life cycle
- A diploid sporophyte produces haploid spores through meiosis
- the spores divide by mitosis and develop into haploid
gametophyte plants
L10: Angiosperms Correct Answer Seeded Vascular Plant
flowering plants that produce seeds in fruit
- DOMINANT LAND PLANT TODAY (96%)
- seed is enclosed in a fleshy fruit
- Fruit eaters as seed dispersers
- specialized reproductive structures: FLOWERS!
,L10: Ascomycota Correct Answer sac fungi
-include colorful molds that attack stored food and destroy crops
- some species produce penicillin
cause Dutch elm disease and chestnut blight
L10: Aspergillus Correct Answer -infects peanuts and stored
grain
-releases aflatoxins
- carcinogenic compounds
L10: Basidiomycota Correct Answer -sexually reproducing
- fruiting bodies; mushrooms, puffballs, shelf fungi, stinkhorns
L10: Candida albicans Correct Answer yeast infection
L10: cellular level of organization Correct Answer An
aggregation of cells that are functionally differentiated and
emphasize one task
no true tissues but definite patterns/ layers evident
example: sponges (porifera)
L10: Charophytes Correct Answer Plants and Green Algae;
both store food as starch and have cell walls made of cellulose;
uses the same type of chlorophyll
L10: Chitin Correct Answer cells are surrounded by cell walls
strengthened by _____
,L10: Chlorophyll Correct Answer pigment found in chloroplast
that captures light energy during photosynthesis
*present in protists and prokaryotes
Absorbs violet, blue, red light BUT REFLECTS GREEN
L10: Chloroplast Correct Answer Site of photosynthesis
L10: Cuticle Correct Answer A waxy covering on the surface
of stems and leaves that acts as an adaptation to prevent
desiccation in terrestrial plants; limits the evaporation of water
L10: Diploid Correct Answer 2N
(genetics) an organism or cell having two sets of chromosomes
or twice the haploid number
L10: early vascular plants Correct Answer - Developed a 2way
nutrient/ water transport system
- True stems, roots, and leaves (adaptations for life on land)
- no evidence for land based reproduction
Ex. Cooksonia
L10: endophyte Correct Answer fungi that live inside leaves or
other plant parts without causing harm; some are toxic parasite,
others produce defense
L10: Examples of fungal symbiotic relationships Correct
Answer - Lichen
, - Mycorrhizae
- Endophytes
L10: Fungal Interactions with Humans Correct Answer - Some
fungi are parasites to plants
- human diseases
- toxins
- food and medicine
L10: Fungi that attack the skin? Correct Answer Athlete's foot,
jock itch, ringwork
L10: Fungus consists of slender threads Correct Answer
Mycelium and Hyphae
L10: Gametes of opposite sex fuse to form Correct Answer
diploid zygotes, which divide by mitosis and develop into
diploid sporophytes
L10: gametophyte Correct Answer Alternation of Generation
Haploid, or gamete-producing, phase of an organism; spores
divide by mitosis and develop into haploid gametophyte plants
produce male and female gametes by mitosis
L10: Gymnosperms Correct Answer Seeded Vascular Plant
non-flowering plants
example: conifers, cycades, and ginkgoes
