Diversity of Plants Chapter 13 Review Questions with Verified Answers ( Graded A+)
Land plants evolved traits that made it possible to colonize land and survive out of water. Adaptations to
life on land include vascular tissues, roots, leaves, waxy cuticles, and a tough outer layer that protects
the spores. Land plants include nonvascular plants and vascular plants. Vascular plants, which include
seedless plants and plants with seeds, have apical meristems, and embryos with nutritional stores. All
land plants share the following characteristics: alternation of generations, with the haploid plant called a
gametophyte and the diploid plant called a sporophyte; formation of haploid spores in a sporangium;
and formation of gametes in a gametangium. - Answers
The land plants are probably descendants of which of these groups?
green algae
red algae
brown algae
angiosperms - Answers green algae
The event that leads from the haploid stage to the diploid stage in alternation of generations is
________.
meiosis
mitosis
fertilization
germinatio - Answers fertilization
Moss is an example of which type of plant?
haplontic plant
vascular plant
diplontic plant
seed plant - Answers haplontic plant
What adaptations do plants have that allow them to survive on land? - Answers The sporangium of
plants protects the spores from drying out. Apical meristems ensure that a plant is able to grow in the
two directions required to acquire water and nutrients: up toward sunlight and down into the soil. The
multicellular embryo is an important adaptation that improves survival of the developing plant in dry
environments. The development of molecules that gave plants structural strength allowed them to grow
higher on land and obtain more sunlight. A waxy cuticle prevents water loss from aerial surfaces.

generations life cycle - Answers haplodiplontic
describes a life cycle in which the haploid stage is the dominant stage - Answers haplontic
having two kinds of spores that give rise to male and female gametophytes - Answers heterosporous
having one kind of spore that gives rise to gametophytes that give rise to both male and female gametes
- Answers homosporous
a plant that lacks vascular tissue formed of specialized cells for the transport of water and nutrients -
Answers `nonvascular plant
(plural: sporangia) the organ within which spores are produced - Answers sporangium
the diploid plant that produces spores - Answers sporophyte
the union of two gametes in fertilization - Answers syngamy
a plant in which there is a network of cells that conduct water and solutes through the organism -
Answers vascular plant

the liverworts
the horsetails
the club mosses
