Question 1

In all plants,gametes unite at fertilization to form a ____.&#10;A)spore&#10;B)gametophyte&#10;C)sporophyte&#10;D)zygote&#10;E)seed

Accepted Answer

Gametes unite at fertilization to form a zygote, which will go on to develop into a multicellular organism. The other options are not correct because: spores are reproductive structures produced by some plants but not formed through fertilization, gametophytes and sporophytes are distinct stages in the life cycle of many plants but not the product of fertilization, and seeds are structures produced by some plants after fertilization but not the actual product of fertilization itself.

Question 2

What agricultural practice encourages the rapid spread of plant diseases? &#160;&#10;A)irrigation practices&#10;B)use of herbicide sprays&#10;C)genetic modification of crops&#10;D)planting large areas with a single crop variety&#10;E)use of pesticides

Accepted Answer

Planting large areas with a single crop variety, also known as monoculture, encourages the rapid spread of plant diseases because the plants are all genetically similar and therefore susceptible to the same pathogens. In contrast, planting different crop varieties and crop rotation can help prevent the spread of diseases because it reduces the concentration of a particular pathogen in one area.

Question 3

Accepted Answer

Rhizoids are threadlike structures that anchor the gametophyte (the sexual phase of the moss life cycle) to the substrate and absorb water and nutrients from it. Mycorrhizae are a type of symbiotic association between fungi and plant roots, fronds are the leaves of ferns, sporangia are structures that produce spores, and rhizomes are a type of stem found in some plants.

Question 7

Accepted Answer

Phloem is responsible for transporting the sugars produced during photosynthesis (glucose and sucrose) from the leaves to other parts of the plant, including the roots, stem, and fruits. This process is called translocation.
