A seed plant that produces flowers. Example: All of these seeds are covered by some kind of fruit. These seed plants have some familiar fruits like apples, plums, maple trees, tulips, rose bushes, and corn. Some are less colorful like grass.
a) gymnosperm
b) angiosperm
c)
d)
The layer in plants that separates the xylem from the phloem.
a) aerial
b) fibrous
c) cambium
d)
The process in which energy is released when the cells of organisms use oxygen to break down the (food) sugars store as starch. During this plant and animal cells produce carbon dioxide and water as waste products, which are then released back in air
a) cambium
b) photosynthesis
c) transpiration
d) cellular respiration
A seed plant that does not produce flowers. They include pines, firs, and other cone-bearing trees. They have hard seeds that are uncovered.
a) gymnosperm
b) angiosperm
c)
d)
The tissue through which food from the leaves moves throughout the rest of a plant. It is a two-way transport route. It flows both up and down in a plant.
a) xylem
b) phloem
c)
d)
The food-making process in green plants that uses sunlight. Organisms burn the sugars produced in ________ during cellular respiration.
a)
b)
c) chlorophyll
d) photosynthesis
The loss of water through a plant's leaves.
a)
b) cellular respiration
c) transpiration
d)
______ is a series of tubes that water and minerals move up through a plant. It is in one direction only - up from the plants roots to the leaves.
a) phloem
b) xylem
c) cambium
d)
These plants are small and survive without a transport system; are very close to the ground to absorb water directly.
a) vascular
b) nonvascular
c)
d)
These plants do not have size limitations. They have a series of hollow tubes that can transport water and nutrients to the top of the tallest trees. They are divided into seed plants and seedless plants.
a) vascular
b) nonvascular
c)
d)
Seedless plants produce ____. They are a single cell that can develop into a new plant exactly like the plant that produced it. They have a tough outer covering. Example: Ferns
a) bulb
b) seed
c) spores
d)
_____ is the part of the plant that absorbs water and minerals, stores food, and anchors the plant. They absorb water using fuzzy root hairs.
a) flower
b) stem
c) leaves

d)
Xylem tissue and phloem tissue make up a plant's transport system.
a) true
b) false
c)
d)
Which part of a root transports water and nutrients?
a) epidermis
b) root cap
c) vascular system
d) cortex

a) cambium.
b) xylem.
c) stomata.
d) phloem.
