Question | Answer |
---|---|
What is the closest parallel in animal structural levels of complexity to the branches, buds, flowers, seeds, and fruits of flowering plants? | E. digestive system, reproductive |
Predict what would occur if you removed the shoot apical meristem of a plant embryo. | A. Growth would only occur at in the roots. |
Root hairs are specialized | B. epidermal cells. |
What do eudicots have that is not present in monocots? | C. netted venation |
What is a feature of woody stems (in temperate regions) but not of herbaceous stems? | A. bud scale scars |
What do you predict would happen if flower growth became indeterminate? | C. The flowers would be enormous. |
A plant that you are studying has sluggish wound healing abilities as well as an inability to store significant food reserves. You would like to enhance these properties. If you could enhance the growth of a tissue to improve these properties, which tis | A. parenchyma of the stem cortex |
How can one distinguish between annuals, biennials, and perennials? | E. the time from seed germination to seed production |
Where is the primary meristem located? | D. root and stem tips |
The mesophyll of the leaf | E. is made up of palisade and spongy parenchyma cells. |
A vascular bundle | A. contains xylem and phloem. |
Where in the eudicot plant root would you expect to find vascular tissue? | A. in the center |
If a cross section of a eudicot herbaceous stem were compared with the cross section of its root, how would they differ? | C. location of vascular tissue |
In terms of adaptation and diversity, what stage of the alternation of generations in flowering plants is analogous to the production of hundreds of fertilized eggs from a pair of wood frogs? | A. gametophyte stage |
What is true of eudicots but not monocots? | A. Eudicots have flower parts usually in multiples of 4 or 5. |
Cell extension involves | D. expansion of cellulose microfibrils. |
Experiments suggest that the KNOX protein is closely associated with what plant hormone during the induction of leaf primordia? | E. gibberellic acid |
Where would one find the leaf axillary bud? | C. between the leaf petiole and the stem |
Scientists discovered that the primary reason leaves either develop as simple or compound is related to | A. whether the KNOX gene is active or not active. |
In the alternation of generations of flowering plant life cycles, the gametophyte stage is most similar to what stage of termite development? | D. fertile queen |
You and your lab partners are studying a plant and find a way to inactivate the SAM. If the plant is to continue living, it will have to find an alternate way to accomplish what essential plant function? | A. biochemical pathways of photosynthesis |
You are a botanist who is immersed in your attempt to increase a certain property in your plant of study. To that end, you induce a mutation that doubles the amount of vascular cambium (a type of meristem) in your plant. Assuming this brings the desired | B. production of secondary xylem and phloem |
As you experiment with microRNA, you find that you are able to disable it entirely. What do you predict would be the primary effect of this on a plant? | D. Leaf shape would be unchanged. |
The apprentice in your horticulture lab accidentally trims all of the axillary buds from a particularly prized specimen. After realizing his mistake, he rather glumly asks you, as lead horticulturalist, about the effects on the plant. | C. the plant will continue its vertical growth and will be a tall and skinny variety. |
Which would be least affected by the loss of guard cell function that closes stomata? | C. a rainforest plant |
