Gametangia
|
Reproductive strcutures that protect gametes as they develop
|
Pollen
|
Reproductive structures that allow sperm to be transported in the abscence of water
|
Seeds
|
Reproductive structures that provide stored nutrients and a protective coat so that offspring can be dispersed by wind away from parent plant
|
Fruit
|
Reproductive structures that provide nutritious tissue around seeds that facilitate dispersal by animals
|
Angiosperm only
|
Fruit
|
All land plants except angiosperms
|
Gametangia
|
Gymnosperms and Angiosperms
|
Pollen and seeds
|
The appearance of cuticle and stomata correlated with what event in the evolution of land plants?
|
Growth on land
|
What impact would the spraying of fungicide have on soil-dwelling organisms?
|
Plant and animal diversity would decrease due to reduced amounts of available phosphorus and nitrogen.
|
When pathogenic fungi are found growing on the roots of grape vines, grape farmers sometimes respond by covering the ground around their vines with plastic sheeting and pumping a gaseous fungicide into the soil. The most important concern of grape farmers who engage in this practice should be that the _____.
|
Fungicide might also kill mycorrhizae
|
The following statements describe something about the body structures or functions of fungi
|
Some fungi secrete digestive enzymes into the environment and then absorb the digested nutrients.
Some fungi can grow as either filamentous or single-celled forms. All fungi are heterotrophs; some species live as decomposers and others as symbionts Mycelia are made up of small-diameter hyphae that form an interwoven mass, providing more surface area for nutrient absorption. |
Fungal mycelia _____
|
Have a large surface area composed of branching hyphae
|
Why is it more difficult to treat fungal infections than bacterial infections in humans?
|
Fungal and animal cells and proteins are similar. Thus, drugs that disrupt fungal cell or protein function may also disrupt human cell or protein function.
|
Based on the idea that fungi have pores between their cell walls, which allow cytoplasm to move from one end of the mycelium to the other, which of the following hypotheses is the most plausible?
|
If a single mycorrhizal fungus formed symbiotic associations with more than one tree, carbon could travel from one plant to another
|
The term gymnosperm refers to plants _____.
|
With "naked seeds"
