Question 2

A plant is observed to have a taproot system. Which of the following is most likely TRUE about this plant?

Accepted Answer

It has a primary root that grows deep into the soil with smaller lateral roots branching off.

Question 3

Which tissue system in plants is primarily responsible for photosynthesis and storage?

Accepted Answer

Ground tissue

Question 4

A botanist discovers a plant with needlelike leaves. What is the most likely adaptive advantage of this leaf type?

Accepted Answer

Reducing water loss in arid or cold environments.

Question 5

Which of the following cell types is most specialized for support in regions of a plant that are still growing?

Accepted Answer

Collenchyma

Question 6

What is the main function of plasmodesmata in plant cells?

Accepted Answer

Facilitating communication and transport of molecules between adjacent cells.

Question 7

Which plastid is directly involved in photosynthesis?

Accepted Answer

Chloroplast

Question 8

A plant cell is placed in a hypotonic solution. Which process will most likely occur, and what structure is responsible for maintaining cell shape?

Accepted Answer

Water will enter the cell; the vacuole and cell wall maintain turgor pressure.

Question 9

Which of the following is NOT a function of the epidermis in plants?

Accepted Answer

Transport of water and nutrients

Question 10

A student is asked to identify a leaf with multiple leaflets attached to a single petiole. Which type of leaf is this?

Accepted Answer

Compound leaf

Question 11

Which equation best represents the relationship between turgor pressure ($P$), osmotic pressure ($	ext{OP}$), and wall pressure ($	ext{WP}$) in a plant cell?

Accepted Answer

$P = 	ext{OP} + 	ext{WP}$

Question 12

Which of the following is a correct sequence of tissues from the outside to the inside of a typical plant stem?

Accepted Answer

Epidermis → Ground tissue → Vascular tissue

Question 13

Which structure is primarily responsible for the transport of water and minerals from roots to shoots?

Accepted Answer

Xylem

Question 14

A plant is found to have high phenotypic plasticity in its root system. What does this mean?

Accepted Answer

Its root system can adapt its structure in response to environmental conditions.

Question 15

Which of the following is TRUE about sclerenchyma cells?

Accepted Answer

They are dead at maturity and provide rigid support.

Question 16

Which part of the leaf is directly attached to the stem?

Accepted Answer

Petiole

Question 17

Which of the following is a function of companion cells in the vascular tissue?

Accepted Answer

Assisting in the loading and unloading of sugars into sieve tubes

Question 18

A plant with a fibrous root system is most likely to be found in which type of environment?

Accepted Answer

An environment where rapid soil erosion occurs and roots help stabilize the soil.

Question 19

Accepted Answer

Storage of starch

Question 20

A plant is observed to have a rhizome. Which statement best describes this structure?
