Fast i'm in a test and i don't know sh*t

1. which two characteristics do seedless vascular plants have that nonvascular plants do not have?
a.) they have phloem and true stems.
b.) they have true roots and use spores to reproduce.
c.) they live in moist environments and have xylem.
d.) they have phloem and use spores to reproduce.

2. a group of land plants performs photosynthesis, has specialized tissues and a cuticle, but does not have seeds.
which hazard of living on land would this group of plants likely struggle with the most?

a.) water loss through leaves
b.) young plant death due to lack of water
c.) transporting water
d.) using the sun’s energy to make food

3. how is the life cycle of seedless vascular plants different from the life cycle of nonvascular plants?

a.) the adult form of each seedless vascular plant has xylem and phloem.
b.) the gametophyte stage is lacking in the life cycle of seedless vascular plants.
c.) the sperm of seedless vascular plants do not need to swim in water.
d.) the zygote of each seedless vascular plant forms before the egg is fertilized.

(1)Seedless vascular plants include ferns, whisk ferns, club mosses, and horsetails. The plants do not produce seeds so, like bryophytes, they are dispersed (spread) by windblown spores. They are vascular plants and therefore have true roots, stems, and leaves. The sperm are flagellated and require water for reproduction. So the answer is (B)

(2)Adaptations that allow seed plants to reproduce without water include flowers or cones, the transfer of sperm by pollination, and the protection of embryos in seeds. Angiosperms develop unique reproductive organs known as flowers. So #2 would be C.

(3) Life Cycle of Seedless Vascular Plants. Unlike nonvascular plants, all vascular plants—including seedless vascular plants—have a dominant sporophyte generation. Seedless vascular plants include clubmosses and ferns. ... The resulting zygote develops into an embryo that becomes a new sporophyte plant. So the answer is (C), because they blow in the wind.

1. B

2. C

3. C

ur welcome.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

gold i'm pretty sure i might be wrong
