Higher Plants Exam 2

During Cellular Respiration, What becomes oxidized?

Sugar (C6H12O6) becomes oxidized to CO2

What is the preferred starting point for glycolysis in photosynthetic tissues during the day?

Glyceraldhehyde-3-phosphate (G3P)

What is Metabolic Redundancy?

Multiple pathways that carry out the same functions

Which of the following fermentation methods can occur most commonly in plants?

Alcohol fermentation

Phenotypes which shows continuous variation (continuous distribution) like wheat, color, are usually results of?

The action of many genes on one trait

Hydrangeas produce blue or pink flowers depending on?

Environmental Effects

Which of the following describes how plants reproduce? (select all that apply)

Plants can reproduce asexually by sending out runners or sucker to make clones of themselves

A Plant part that has broken off (such as a leaf or stem) can de-differentiate its cell and redifferentiate them into needed body parts and grow a whole new plant

Plants have an entire haploid stage of life that produces gametes by mitosis, which then combine with another gamete in sexual reproduction.

A flowering plant has some green leaves, some white leaves and some varigated (mixed color) leaves. If the pollen from a flower on a white leafed stem lands on flower on the flower from an all green leafed stem, the offspring will most like have?

All green leaves

If a plant reproduces by selfing, that is, the pollen from a flower lands on the stigma from the same flower, it is

Sexual Reproduction

In plants, which of the following are produced stigma by meiosis?

Haploid Spores

A dioecious plant is one that

Produce either male flowers or female flowers, but not both

Double fertilization means that

One sperm is needed to fertilize the egg while the second is needed to combine with the polar nuclei

In flowering plants that exhibit self-incompatibility, the S gene plays a critical role on preventing self-fertilization. What is the primary function of the S gene in this process?

It enables recognition and blocks germination of pollen originating on the same plant or very closely related plants to prevent inbreeding

In most flowering plants, polarity is established after the ___ division of the zygote

First

A seed is said to be dormant when it:

Does not germinate when conditions of oxygen, water, and temperature are favorable

A recalcitrant seed is one that?

Retain moisture and metabolic activity

All seeds have which structure in common (select all that apply)?

Embryo

Food Storage tissue

Seed Coat

The procabium gives rise to

Vascular Tissue

The radicle is

The primary root that emerges first from the seed

What are cotyledons

The first leaves that appear from germinating seed and provide nutrients to the seedling
