Question 1

Which of the following best describes the main difference between mitosis and meiosis in the cell cycle?

Accepted Answer

Mitosis produces two genetically identical diploid cells, while meiosis produces four genetically unique haploid cells.

Question 2

A researcher observes a fungus growing on bread. Which of the following characteristics would help confirm it belongs to Kingdom Fungi?

Accepted Answer

It has cell walls made of chitin and reproduces by spores.

Question 3

Which phase of the cell cycle is primarily responsible for DNA replication?

Accepted Answer

S phase

Question 4

A moss is an example of which type of plant, and what is a key feature of its life cycle?

Accepted Answer

Non-vascular plant; dominant gametophyte generation

Question 5

Which equation correctly represents the process of cellular respiration, a process that occurs during the cell cycle?

Accepted Answer

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

Question 6

Which of the following is a major evolutionary advantage of seedless vascular plants over non-vascular plants?

Accepted Answer

Presence of vascular tissue for efficient water and nutrient transport

Question 7

A student observes a plant with xylem and phloem but no seeds. To which group does this plant most likely belong?

Accepted Answer

Seedless vascular plants

Question 8

Which of the following best explains why fungi are classified as heterotrophs?

Accepted Answer

They absorb nutrients from organic matter in their environment.

Question 9

During which stage of mitosis do sister chromatids separate and move toward opposite poles?

Accepted Answer

Anaphase

Question 10

Which of the following statements about the alternation of generations in plants is correct?

Accepted Answer

The sporophyte is diploid and produces spores by meiosis.

Question 11

A patient is diagnosed with a fungal infection. Which of the following cellular features would you expect to find in the pathogen?

Accepted Answer

Cell walls made of chitin

Question 12

Which of the following best describes the function of the G2 checkpoint in the cell cycle?

Accepted Answer

Ensures DNA has been accurately replicated before mitosis

Question 13

Which of the following is a key ecological role of fungi in the environment?

Accepted Answer

Decomposers that recycle nutrients

Question 14

Which of the following correctly matches a plant group with its dominant life cycle stage?

Accepted Answer

Mosses – gametophyte

Question 15

A scientist discovers a new organism that is multicellular, has cell walls, and absorbs nutrients from decaying matter. Which kingdom does this organism most likely belong to?

Accepted Answer

Fungi

Question 16

Which of the following is a characteristic unique to seedless vascular plants compared to non-vascular plants?

Accepted Answer

Presence of true roots, stems, and leaves

Question 17

Which of the following best explains why non-vascular plants are typically found in moist environments?

Accepted Answer

They require water for sperm to swim to the egg during reproduction.

Question 18

Which of the following equations represents the process of photosynthesis in plants?

Accepted Answer

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

Question 19

Which of the following best describes the role of spores in the life cycle of fungi?

Accepted Answer

Spores are produced by meiosis and allow fungi to disperse and reproduce.

Question 20

A mutation occurs in a plant that prevents the formation of phloem. Which process would be most directly affected?

Accepted Answer

Transport of sugars from leaves to other parts of the plant
