10What is the difference between complete and incomplete flowers? Complete flowers have [blank_start]sepals[blank_end], [blank_start]petals[blank_end], [blank_start]stamens[blank_end], and [blank_start]pistils[blank_end]; incomplete flowers lack one or more of these four basic parts.
- Asepals
- Bpetals
- Cstamens
- Dpistils
11What is the difference between staminate and pistillate flowers? Staminate, or male, flowers lack pistils and bear only [blank_start]stamens[blank_end]; pistillate, or [blank_start]female[blank_end], flowers lack stamens and bear only [blank_start]pistils[blank_end].
- Astamens
- Bfemale
- Cpistils
12Explain the difference between monoecious plants and dioecious plants. A monoecious plant produces both [blank_start]staminate[blank_end] and [blank_start]pistillate[blank_end] flowers. A [blank_start]dioecious[blank_end] plant may produce staminate [blank_start]or[blank_end] pistillate flowers, but the two types of flowers are born by [blank_start]separate[blank_end] plants.
- Astaminate
- Bpistillate
- Cdioecious
- Dor
- Eseparate
13Distinguish between self-pollination [blank_start]and[blank_end] cross-pollination.
- Aand
14Distinguish between self-pollination and cross-pollination. In self-pollination, pollen from the anther is transferred to the stigma of a pistil in the [blank_start]same[blank_end] flower or to the another flower of the [blank_start]same[blank_end] [blank_start]plant[blank_end]. In cross-pollination, the pollen from an anther of one plant is transferred to a stigma of a flower on [blank_start]another[blank_end] [blank_start]plant[blank_end].
- Asame
- Bsame
- Cplant
- Danother
- Eplant
15How does pollination lead to fertilization and the development of a seed? Pollination is the transfer of [blank_start]pollen[blank_end] from an [blank_start]anther[blank_end] to the [blank_start]stigma[blank_end] portion of a pistil. Pollination brings sperm cells to the [blank_start]pistil[blank_end], making fertilization possible.
Fertilization is the fusion of a [blank_start]sperm[blank_end] cell with an [blank_start]egg[blank_end] cell within the ovule. Fertilization determines the blueprint for the new [blank_start]plant[blank_end] and triggers the development of the [blank_start]seed[blank_end] and fruit.- Apollen

- Cstigma
- Dpistil

- Hseed
16Explain the difference between simple fruits, aggregate fruits, and multiple fruits. Simple fruits form from a [blank_start]single[blank_end] flower with only [blank_start]one[blank_end] pistil. Aggregate fruits form from [blank_start]one[blank_end] flower that has [blank_start]several[blank_end] pistils. Multiple fruits form from [blank_start]several[blank_end] flowers.
- Asingle
- Bone
- Cone
- Dseveral
- Eseveral
17Describe the stages of germination of a bean seed.
When a bean is planted and begins to germinate, it absorbs a great deal of [blank_start]water[blank_end]. The presence of water triggers chemical changes, causing the [blank_start]embryo[blank_end] to swell and grow. The water also softens the [blank_start]seed[blank_end] [blank_start]coat[blank_end] so that the root and [blank_start]shoot[blank_end] can push through the coat and begin growing into the soil.- Awater

- Cseed
- Dcoat
- Eshoot
18Why does whole wheat flour tend to be more nutritious than white flour?
When white flour is made, the [blank_start]bran[blank_end] and [blank_start]germ[blank_end], which contain most of the nutrients are removed during the milling process; the extra processing and bleaching also causes some loss of [blank_start]nutrients[blank_end] (although vitamins and minerals are commonly added during processing).- Abran
- Bgerm
- Cnutrients
19The primary function of fruits is to [blank_start]scatter the plant's seeds.[blank_end]
- Ascatter the plant's seeds.
20Two kinds of seed dispersal are [blank_start]agent[blank_end] dispersal and [blank_start]mechanical[blank_end] dispersal.
- Aagent
- Bmechanical
21[blank_start]Agent[blank_end] dispersal is when an outside [blank_start]agent[blank_end] such as an animal, a man, the wind, or water, carries the seeds to good soil.
- AAgent
- Bagent
22[blank_start]Mechanical[blank_end] dispersal is when the fruit scatters its seeds by bursting open when they are ripe to catapult them to a new location.
- AMechanical
23Which method of seed dispersal (agent or mechanical) can spread seeds farther from the plant?
[blank_start]Mechanical[blank_end] dispersal is limited to the maximum distance that a seed can be thrown, which would be a few yards at the most. [blank_start]Agent[blank_end] dispersal, on the other hand, can carry seeds for hundreds or even thousands of miles by means of winds, flowing water, or migrating animals.- AMechanical
- BAgent
24A viable seed is one that is still able to [blank_start]germinate[blank_end].
- Agerminate
