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
Which type of fleshy fruit contains a single seed encased in a pit. Examples include plums, almonds, peaches, and cherries.
a. Berry
b. Drupe
c. Hesperidium
d. Pome
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 five phyla require water for reproduction due to their production of sperm as the male gamete?
Bryophyta, Hepatophyta, Anthocerophyta, Lycophyta, Monilophyta
Which four phyla produce seeds but no fruits?
Coniferophyta, Ginkophyta, Gnetophyta, Cycadophyta
Which three phyla have the gametophyte as the dominant generation?
Bryophyta, Heptophyta, Antocerophyta
Which three phyla lack vascular tissues?
Bryophyta, Heptophyta, Antocerophyta
Which two phyla have vascular tissue but do not produce seeds?
Lycophyta and Monilophyta
Which phylum contains the flowering plants that produce fruit containing seeds?
Anthophyta
Which of the following cells has a thinner primary cell wall and is somewhat flexible in metabolically active cells?
a. Collenchyma
b. Parenchyma
c. Sclerenchyma
b. Parenchyma
Monocots and eudicots are two groups in which plant phylum?
a. Anthophyta
b. Bryophyta
c. Coniferophyta
d. Monilophyta
a. Anthophyta
Which cells compose the xylem?
Tracheids and vessel elements
Which cells compose the phloem?
Companion cells, sieve tube elements, and sclerenchyma cells
Which of the following meristematic tissues results in lateral roots?
a. Cork cambium
b. Pericycle
c. Primary meristem
d. Vascular cambium
b. Pericycle
What are the two components of a leaf?
a. Blade
b. Petiole
c. Pith
d. Stem
a. Blade and b. Petiole
Which group(s) of plants has/have vascular bundles of the stem arranged in a ring around a central pith?
a. Monocots
b. Herbaceous eudicots
c. Woody eudicots
d. All of the above
b. Herbaceous eudicots
Which group(s) of plants has/have a vascular cylinder (stele) surrounded by an endodermis and Casparian strip in the roots?
a. Monocots
b. Herbaceous eudicots
c. Woody eudicots
d. All of the above
d. All of the above
Which group(s) of plants has/have parallel leaf venation?
a. Monocots
b. Eudicots
c. Both Monocots and Eudicots
a. Monocots
Which of the following is not present in/on a plant seed?
a. Food for embryo
b. Protective seed coat
c. Young embryonic gametophyte
d. Young embryonic sporophyte
c. Young embryonic gametophyte
What does the periderm do?
It replaces the epidermis and cortex with secondary growth.
Why is the endodermis necessary for the roots, but not the stem of the plants?
The endodermis determines what the plant allows to access the vascular tissue system. It is not essential in the stem because stems do not absorb anything.
