Accepted Answer

Monocots

Question 5

Which function is NOT typically associated with the stem of an angiosperm?

Accepted Answer

Absorbing water and nutrients from soil

Question 6

Which equation correctly represents the calculation for your proportion of the highest point total in a class assignment?

Accepted Answer

$$	ext{Your proportion} = \frac{	ext{Your point total}}{	ext{Highest point total in class}}$$

Question 7

Which of the following is a function of root hairs in angiosperms?

Accepted Answer

Increasing the root’s absorptive surface area

Question 8

A plant biologist is studying the effect of an exotic herbivore on a native plant species. Which scenario best illustrates a real-world application of this research?

Accepted Answer

Examining how Rhinocyllus conicus affects Cirsium undulatum populations

Question 9

Which of the following best describes the alternation of generations in plants?

Accepted Answer

A life cycle with both multicellular diploid (sporophyte) and multicellular haploid (gametophyte) stages

Question 10

Which of the following is a function of leaves in angiosperms that is NOT directly related to photosynthesis?

Accepted Answer

Attracting pollinators

Question 11

Which tissue type in angiosperms is most likely to contain cells with chloroplasts and be involved in photosynthesis?

Accepted Answer

Ground tissue

Question 12

A student is asked to identify the arrangement of vascular bundles in a cross-section of a stem. If the bundles are scattered throughout the ground tissue, which type of plant is it most likely from?

Accepted Answer

Monocot

Question 13

Which of the following is NOT a function of dermal tissue in angiosperms?

Accepted Answer

Conducting photosynthesis

Question 14

Which of the following best explains why spines on a cactus are considered modified leaves?

Accepted Answer

They defend the plant against herbivores

Question 15

If a student wants to maximize their final grade in Biol 211, which strategy is most effective based on the grading breakdown?

Accepted Answer

Prioritize lab performance, as it has the highest proportional contribution

Question 16

Which of the following is a correct sequence in the alternation of generations life cycle in plants?

Accepted Answer

Sporophyte (2n) → Meiosis → Spores (1n) → Mitosis → Gametophyte (1n)

Question 17

Which of the following best describes the main function of xylem in vascular tissue?

Accepted Answer

Transporting water and inorganic nutrients from roots to shoots

Question 18

A researcher finds that insect damage to a less preferred host plant increases when the preferred host is nearby and abundant. What ecological concept does this illustrate?

Accepted Answer

Apparent competition

Question 19

Which of the following is a correct formula for calculating your final percentage in Biol 211, based on the grading scheme?

Accepted Answer

$$	ext{Final Percentage} = \sum (	ext{Your percentage} 	imes 	ext{Proportional contribution})$$
