Lab Exam #1 Flashcards
Plants are in Domain ___ and Kingdom ___.
Eukarya; Plantae
Plants alternate between the gametophyte and sporophyte generations. The gametophyte generation is haploid/diploid and produces gametes/spores while the sporophyte generation is haploid/diploid and produces gametes/spores.
haploid, gametes; diploid, spores
The cell wall of a plant is composed of what carbohydrate?
Cellulose
In what form of carbohydrate does a plant store its food?
Starch
What are the two types of vascular tissue, what does each transport, and in what direction?
Xylem transports water and minerals upwards. Phloem transports sugar in both directions.
How odes pollination of gymnosperms differ from pollination of most angiosperms that have brightly colored flowers?
The pollination of gymnosperms is reliant on the wind to transport pollen. Angiosperms with bright flowers can attract pollinators to transport pollen.
Which flower structures are part of the carpel/pistil?
Ovule, ovary, stigma, style
Which flower structures are part of the stamen?
Anther, filament

b. Drupe
Which two of the following dry fruits are similar in both are one-seeded fruit where the seed is attached to the fruit at only one point (hint: one has a wing and the other does not)?
a. Achene
b. Legume
c. Nut
d. Samara
a. Achene and d. Samara

Which three phyla have the gametophyte as the dominant generation?
Bryophyta, Heptophyta, Antocerophyta
Which three phyla lack vascular tissues?
