Accepted Answer

They produce seeds within fruits formed from ripened ovaries.

Question 2

A botanist is examining a plant with parallel leaf venation, scattered vascular bundles in the stem, and fibrous roots. Which class does this plant most likely belong to?

Accepted Answer

Class Monocotyledonae (Monocots)

Question 3

Which type of plant cell is least specialized, has a thin primary cell wall, and is the main site of metabolism and storage in plants?

Accepted Answer

Parenchyma cell

Question 4

Which tissue system in plants is primarily responsible for transporting water and minerals from roots to shoots?

Accepted Answer

Vascular tissue (specifically xylem)

Question 5

A plant stem cross-section shows vascular bundles arranged in a ring, with xylem closer to the center and phloem closer to the epidermis. This arrangement is typical of:

Accepted Answer

Dicot stems

Question 6

Which equation best represents the process of photosynthesis occurring in the ground tissue of leaves?

Accepted Answer

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

Question 7

Which of the following is TRUE about meristematic tissue in plants?

Accepted Answer

It is responsible for indeterminate growth and is found at both shoot and root tips.

Question 8

A plant is described as monoecious. What does this mean regarding its flowers?

Accepted Answer

It has flowers with both stamens and carpels on the same plant.

Question 9

Which cell type provides flexible support to growing regions of a plant due to its unevenly thickened primary cell walls?

Accepted Answer

Collenchyma cells

Question 10

Which structure in the root is responsible for regulating the movement of water and minerals into the vascular tissue?

Accepted Answer

Endodermis

Question 11

A plant with netlike leaf venation, a taproot system, and vascular bundles arranged in a ring is most likely a:

Accepted Answer

Dicot

Question 12

Which of the following is a function of the cork cambium in woody plants?

Accepted Answer

It produces periderm and cork cells, contributing to secondary growth.

Question 13

Which plant tissue is made up of tightly packed cells and often covered by a waxy cuticle to prevent water loss?

Accepted Answer

Dermal tissue (epidermis)

Question 14

Which of the following fruits is classified as an accessory fruit, meaning it develops from tissues other than the ovary?

Accepted Answer

Strawberry

Question 15

Which type of plant cell has a thick secondary cell wall containing lignin and is dead at maturity, providing rigid support?

Accepted Answer

Sclerenchyma cell

Question 16

Which of the following best describes the function of sieve-tube elements in phloem tissue?

Accepted Answer

They transport sucrose and other organic nutrients throughout the plant.

Question 17

A plant is observed to grow continuously throughout its life, producing new leaves and flowers each season. This type of growth is called:

Accepted Answer

Indeterminate growth

Question 18

Which of the following is a correct comparison between monocot and dicot roots?

Accepted Answer

Monocots have fibrous root systems, while dicots have a taproot system.

Question 19

Which structure in the leaf is responsible for gas exchange and is regulated by guard cells?

Accepted Answer

Stomata

Question 20

A plant is classified as a perennial. What does this mean about its life cycle?

Accepted Answer

It lives and reproduces for more than two years.
