Question 1

How could you show experimentally that photosynthesis is important for plant growth?&#10;A)Remove different numbers of leaves from plants in each test group, and measure their growth under the same conditions&#10;B)Expose groups of plants to different amounts of sunlight&#10;C)Test the effect of painting leaves of an experimental group with clear nail polish

Accepted Answer

By exposing groups of plants to different amounts of sunlight, you can directly observe the impact of photosynthesis on plant growth, as sunlight is a key factor in the photosynthesis process.

Question 2

To which of the two main pant organ systems do stems belong?&#10;A)roots&#10;B)dermal tissue&#10;C)shoots

Accepted Answer

Stems belong to the shoot system, which includes the above-ground parts of plants such as leaves, stems, and flowers. The root system is a separate organ system that includes underground roots. The dermal tissue is a type of tissue found in both the shoot and root systems that forms the outer protective layer of plants.

Question 3

How would you test to see if organic nitrogen was required for optimal plant growth?&#10;A)set up an experiment using different amounts of atmospheric nitrogen&#10;B)set up an experiment using different amounts of nitrogen fertilizer&#10;C)set up an experiment using different amounts of atmospheric carbon dixoide

Accepted Answer

The best way to test if organic nitrogen is required for optimal plant growth is to set up an experiment using different amounts of nitrogen fertilizer. This will allow you to see if the plants grow differently when given varying amounts of a nitrogen source that is not organic in nature. Set up a control group with no nitrogen fertilizer as a comparison. Testing atmospheric nitrogen or carbon dioxide would not be directly relevant to investigating the requirement for organic nitrogen in plant growth.

Question 4

Scientists refer to the water potential of a plant in describing how water moves through a plant.Which of the following statements about the water potential is false?&#10;A)Water moves only when the water potential of the entire system is greater than or less than zero.&#10;B)Water moves only when the water potential of the entire system is equal to zero.&#10;C)Water moves in the plant as a result of changes in one or more variables including solute concentration, pressure, and matric potentials.

Accepted Answer

Water moves through a plant when the water potential of the entire system is either greater than or less than zero, not when it is equal to zero. In other words, water moves from areas of high water potential to areas of lower water potential. The water potential is affected by solute concentration, pressure, and matric potentials, which can cause water to move into or out of plant cells.

Question 5

Stems carry water through ________tissue and nutrients through _________tissue.(Outcome #6a)&#10;A)ylem, phloem&#10;B)phloem, xylem&#10;C)veins, arteries

Accepted Answer

Xylem tissue carries water and minerals from the roots to the rest of the plant, while phloem tissue carries nutrients, such as sugars, from the leaves to the rest of the plant. Therefore, option A is the correct choice as it correctly identifies the tissues responsible for carrying water and nutrients in plants. Option B is incorrect as it has switched the functions of phloem and xylem, and option C is incorrect as veins and arteries are used to transport blood in animals, not water and nutrients in plants.

Question 6

Which of the following is not usually part of a typical leaf?&#10;A)lamina&#10;B)midrib&#10;C)tendrils

Accepted Answer

Tendrils are not typically part of a leaf. They are specialized structures for climbing or support found in some plants such as peas and grapevines. The lamina (also called blade) and midrib are usually present in a leaf, with the lamina being the flattened, expanded part of the leaf and the midrib being the central vein that supports it.

Question 7

Plant tissue systems fall into two general categories.What are they?&#10;A)permanent and meristematic&#10;B)non-permanent and meristematic&#10;C)permanent and non-meristematic

Accepted Answer

Plant tissue systems can be classified as either permanent or meristematic. Permanent tissues are derived from meristematic tissues and no longer have the ability to divide. Meristematic tissues, on the other hand, retain the ability to divide and give rise to new cells.

Question 8

Root systems fall into two major categories:________________.(Outcome #Via)&#10;A)bulb and tuber&#10;B)tap and fibrous&#10;C)monocot and dicot

Accepted Answer

Root systems can be categorized as taproot or fibrous root systems. Taproot systems have one main root that grows straight down and smaller lateral roots branching off of it. Fibrous root systems have many smaller roots that spread out in all directions from the base of the plant. The other two choices (A and C) refer to types of plants or plant structures, not root systems.

Question 9

Annual growth rings in trees are the result of what?&#10;A)the cyclical growth and death of ground tissues in the phloem&#10;B)the seasonal variation in vascular cambium, consisting of the development of thin cell walls in secondary xylem in the spring and thicker cells walls in secondary xylem in the fall.&#10;C)the annual variation in rapid growth in the apical meristems that results in the thickening of the cork cambium layers.

Accepted Answer

Annual growth rings in trees are the result of the seasonal variation in vascular cambium, consisting of the development of thin cell walls in secondary xylem in the spring and thicker cell walls in secondary xylem in the fall. This results in the alternating light and dark bands seen in the cross-section of a tree trunk.

Question 10

The leaves of plants serve as the primary sites of what?&#10;A)reproduction&#10;B)growth&#10;C)photosynthesis

Accepted Answer

The leaves of plants contain chloroplasts that are responsible for photosynthesis, the process by which plants convert sunlight into energy to fuel their growth and development. While reproduction and growth also occur in leaves, photosynthesis is their primary function.
