plants to live in drier habitats
Pores called ______enable plants to exchange oxygen and
A pair of specialized cells called _____
borders each stoma
tissue that contains soft-walled conducting
cells that transport organic nutrients
tissue that contains hard-walled conducting
cells that transport water and mineral nutrients
the part of a plant that grows upward
the part of a plant that grows downward
zones of actively dividing plant cells
All nonvascular plants are small and relatively simple
The sporophytes of nonvascular plants are larger than the gametophytes
Nonvascular plants do not have true roots; rhizoids anchor the
gametophytes to the surfaces on which they grow.
Eggs and sperm of nonvascular plants form in separate structures, which
are often on separate plants.
Sporophytes of nonvascular plants grow on the gametophytes and depend
on them for nutrients
Seedless vascular plants have horizontal underground stems called [roots / rhizomes].
Seedless vascular plants have a vascular system with [xylem and phloem / xylem]
xylem and phloem
The much smaller [gametophyte / sporophyte] of seedless vascular plants develops on
or below the surface of the soil.
Seedless vascular plants without roots and leaves are called [whisk ferns / horsetails].
The sporophytes of [ferns / club mosses] have a rhizome that is anchored by roots and
leaves called fronds.
. In some species of [club mosses / ferns], clusters of nongreen spore-bearing leaves
form a structure called a cone.
The flowers of some angiosperms are adapted for wind pollination
The primary function of a fruit is to nourish a plant embryo.
The seeds of an angiosperm have a supply of stored food, called
endosperm, at some time during their development.
The purpose of flowers is to prevent self-pollination.
Wheat, corn, rice, and lawn grasses are dicots.
Plants that produce leaves with parallel veins are monocots
