Question 1

Which of the following tissue types will produce root hairs within the zone of maturation?

Accepted Answer

Root hairs are extensions of the epidermal cells in the zone of maturation, increasing the surface area for water and nutrient absorption.

Question 2

Identify the incorrect pairing of tissue type with cell type.

Accepted Answer

Epidermal tissue is composed of parenchyma cells, not collenchyma cells.

Question 3

Strawberry plants vegetatively reproduce by forming new plants where the nodes of stolons touch the ground.

Accepted Answer

Strawberry plants use stolons, also known as runners, to reproduce asexually. When the nodes of these stolons touch the ground, they can form roots and develop into new plants.

Question 4

Describe three of the key features that you can use to identify whether a plant is a monocot or a eudicot.

Accepted Answer

The answer of Describe three of the key features that...

Question 5

The shoot system of the plant is the aboveground portion that includes stems and leaves for capturing the energy of sunlight.

Accepted Answer

The shoot system of a plant consists of the aboveground parts, including stems and leaves, which are responsible for photosynthesis by capturing sunlight.

Question 6

The outer annual rings where transport occurs is called heartwood.

Accepted Answer

Heartwood is the central, non-living part of a tree trunk, while the outer rings where transport occurs are called sapwood.

Question 7

Vascular tissue extends through the roots,stems,and leaves of the entire plant.

Accepted Answer

Vascular tissue, which includes xylem and phloem, is responsible for the transport of water, nutrients, and food throughout the plant, and it extends through the roots, stems, and leaves.

Question 8

Which of the following features are necessary to classify a plant as a monocot?

Accepted Answer

Monocots are characterized by having one cotyledon, parallel veins in the leaves, and flowers typically in multiples of threes.

Question 9

Which of the following tissue types are found only in the zone of cell division of the root tip?

Accepted Answer

Ground meristem is the only tissue type found only in the zone of cell division of the root tip.

Question 10

Describe the pathway that a drop of water would go through starting at the root system and leaving at the leaf.Be sure to indicate the various tissue types that the water will come in contact with along its pathway.

Accepted Answer

The answer of Describe the pathway that a drop of...

Question 11

Monocot roots have centrally located ground tissue called pith,surrounded by a ring of xylem and phloem bundles.

Accepted Answer

Monocot roots typically have a central pith surrounded by vascular tissue, which includes xylem and phloem arranged in a ring.

Question 12

Mycorrhizae are associations between bacteria and the roots of select plants.

Accepted Answer

Mycorrhizae are associations between fungi and the roots of plants, not bacteria.

Question 13

Farmers have been able to genetically engineer a wide variety of crops that possess an enormous diversity of traits.If a farmer wanted to increase the ability of his crops to access ground water that is several meters below ground which type of root system would he want?

Accepted Answer

A taproot system is characterized by a single, large, deep root that can grow several meters into the ground, making it ideal for accessing deep ground water.

Question 14

Which of the following structures is a stem adaptation instead of a root adaptation?

Accepted Answer

All the listed structures (stolons, rhizomes, tubers, and corms) are adaptations of stems, not roots.

Question 15

Many homeowners often attempt to transplant bushes and small trees but with limited success.Which of the following is the most likely reason for this?

Accepted Answer

Most homeowners pull the bush out without clearing enough of the soil from around the root system. This causes the lateral roots and root hairs to be torn off.

Question 16

During the spring and fall each year thousands of maple trees are tapped for their fluids in order to make "real" maple syrup.If you were to tap into a maple tree to extract the syrup (sucrose)which tissue layer do you want to tap into?

Accepted Answer

The phloem is the tissue responsible for transporting sugars and other organic nutrients throughout the plant, including the sap used to make maple syrup.

Question 17

An insect destroying the ________ layer of tissues in a leaf would lead to a decrease in the ability of gas exchange within the leaf.

Accepted Answer

The spongy mesophyll layer in a leaf contains loosely packed cells with air spaces that facilitate gas exchange. Destruction of this layer would hinder the leaf's ability to exchange gases effectively.

Question 18

A typical leaf is composed of multiple layers of specialized cells.What is the correct order of layers starting on the upper surface of the leaf and progressing to the lower surface?

Accepted Answer

The cuticle is a waxy layer that covers the upper surface of the leaf, followed by the epidermis, which is a layer of tightly packed cells. Below the epidermis is the palisade mesophyll, which is a layer of elongated cells that contain chloroplasts. The spongy mesophyll is a layer of loosely packed cells that also contain chloroplasts. The lower surface of the leaf is covered by another layer of epidermis, which is followed by the cuticle.

Question 19

Explain how various leaves have evolved to capture insects.

Accepted Answer

The answer of Explain how various leaves have evolved to...

Question 20

Considering that leaf stoma have the conflicting functions of allowing gaseous carbon dioxide into the leaf,yet preserving the plant's supply of water,which of the following is (are)reasonable?

Accepted Answer

All the choices are reasonable because submerged-water plants do not need stoma for gas exchange, tree leaves with flat orientation have stoma on the bottom to reduce water loss, and monocots with upright leaves have stoma on both sides due to equal sunlight exposure.
