Question 1

The word meristem is derived from a Greek word meaning to divide.

Accepted Answer

The Greek word "meristem" is derived from "merizein" which means to divide.

Question 2

The root zone of maturation is immediately above the root apical meristem (RAM).

Accepted Answer

The root zone of maturation is located above the zone of elongation, which is above the root apical meristem (RAM). The RAM is at the tip of the root, followed by the zone of elongation, and then the zone of maturation.

Question 3

The apprentice in your horticulture lab accidentally trims all of the axillary buds from a particularly prized specimen.After realizing his mistake,he rather glumly asks you,as lead horticulturalist,about the effects on the plant.You predict that

Accepted Answer

Axillary buds are responsible for the growth of branches and leaves. When they are removed, the plant will not be able to grow new branches or leaves from those points, leading it to focus its energy on vertical growth through the apical meristem, resulting in a taller and skinnier plant.

Question 4

You and your lab partners are studying a plant and find a way to inactivate the SAM.If the plant is to continue living,it will have to find an alternate way to accomplish what essential plant function?

Accepted Answer

SAM is involved in the biochemical pathways of photosynthesis.

Question 5

You are a botanist who is immersed in your attempt to increase a certain property in your plant of study.To that end,you induce a mutation that doubles the amount of vascular cambium (a type of meristem)in your plant.Assuming this brings the desired effect,what exactly was the property that you sought to increase?

Accepted Answer

The vascular cambium is the type of meristem responsible for the production of secondary xylem and phloem, which increases the girth of the stem or root. Therefore, inducing a mutation that doubles the amount of vascular cambium would likely increase the production of secondary xylem and phloem, which is the property the botanist sought to increase.

Question 6

Flowers develop as a result of determinate shoot growth.

Accepted Answer

Flowers are formed from the determinate shoot growth, which means that the growth of the shoot ends with the formation of a flower bud. This is in contrast to indeterminate shoot growth, which continues to grow and produce new leaves and shoots.

Question 7

In the alternation of generations of flowering plant life cycles,the gametophyte stage is most similar to what stage of termite development?

Accepted Answer

The answer of In the alternation of generations of flowering...

Question 9

As you experiment with microRNA,you find that you are able to disable it entirely.What do you predict would be the primary effect of this on a plant?

Accepted Answer

MicroRNA plays a role in regulating gene expression, including genes involved in leaf shape. Disabling microRNA would likely affect the plant's ability to change leaf shape.

Question 10

Which would be least affected by the loss of guard cell function that closes stomata?

Accepted Answer

Rainforest plants are in a humid environment with abundant water, so they are less dependent on stomatal closure to conserve water compared to plants in drier environments.
