Question 1

Which part of the seed is primarily responsible for storing nutrients for the developing embryo?

Accepted Answer

Endosperm

Question 2

During seed germination, which structure emerges first from the seed?

Accepted Answer

The radicle (root)

Question 3

Which of the following is NOT a characteristic of monocot plants?

Accepted Answer

Vascular bundles arranged in a ring

Question 4

What is the main function of the seed coat?

Accepted Answer

To protect the internal parts of the seed

Question 5

Which of the following best describes the function of xylem in plants?

Accepted Answer

Transports water and dissolved minerals upward

Question 6

A plant is observed to have net-like leaf veins, a taproot, and flower parts in multiples of 4 or 5. Which type of plant is this?

Accepted Answer

Dicot

Question 7

What is the evolutionary significance of megaphylls in plants?

Accepted Answer

They result from webbing between vascular tissues, increasing photosynthetic area

Question 8

Which of the following is a function of feeder roots?

Accepted Answer

Absorbing water and nutrients

Question 9

If feeder roots are damaged, what is the most likely consequence for the plant?

Accepted Answer

Wilting and nutrient deficiencies

Question 10

Which structure in the plant is responsible for controlling the opening and closing of stomata?

Accepted Answer

Guard cells

Question 11

What is the primary purpose of seed dormancy?

Accepted Answer

To prevent germination during unfavorable environmental conditions

Question 12

Which tissue is responsible for transporting sugars produced during photosynthesis to other parts of the plant?

Accepted Answer

Phloem

Question 13

A botanist observes a plant with scattered vascular bundles, parallel leaf veins, and fibrous roots. Which of the following best describes this plant?

Accepted Answer

Monocot

Question 14

Which of the following is NOT a function of the root zone in plants?

Accepted Answer

Photosynthesis

Question 15

Which sequence correctly describes the order of plant structures from the outside inward in a dicot stem?

Accepted Answer

Phloem → Cambium → Xylem

Question 16

Which of the following best explains why monocots do not have cambium?

Accepted Answer

Monocots do not increase in girth through secondary growth

Question 17

A plant is unable to transport water from its roots to its leaves. Which tissue is most likely malfunctioning?

Accepted Answer

Xylem

Question 18

Which of the following is a real-world example of seed dormancy being beneficial?

Accepted Answer

Seeds remain dormant until spring, avoiding frost damage

Question 19

Which formula best represents the process of photosynthesis that occurs after leaves develop?

Accepted Answer

$$6CO_2 + 6H_2O \rightarrow C_6H_{12}O_6$ + 6O_2$$

Question 20

Which of the following best describes the role of stomata in plant survival during drought conditions?

Accepted Answer

Stomata close to reduce water loss through transpiration
