Plant Quiz Review Sheet
1) Non-Vascular Plants - lack vascular tissues. Do not have true roots, stems or leaves. Non-vascular
plants rely on the processes of osmosis and diffusion to get needed materials.

Grow in moist environments

Low to the ground
Examples: mosses, liverworts
2) Vascular Plants - use vascular tissues. Vascular plants have xylem
and phloem. These tube like structures are used to transport
water, minerals, and sugar to different areas of the plant.
Examples: all other plants – ferns, conifers (cone-bearing
plants), flowering plants.
Two kinds of Vascular Tissue:
Xylem - transports water and minerals from the roots to the leaves
Phloem - transports sugar molecules from the leaves to the stem/roots
 Plants usually have a waxy, protective layer called a cuticle that holds in moisture. Gas exchange can
occur through small openings in the leaves called stomata.
There are three types of Vascular Plants
1) Vascular seedless - Have stems, but no seeds.
Reproduce with spores as seen on the backs
of ferns. Examples: ferns, horsetails, club mosses
Name____________________
2) Gymnosperms - Usually produce seeds in cones.
Rely on wind and water to transport pollen from male cone to female
cone.
Examples: conifers (pine trees), gingkoes, palms
3) Angiosperms - produce seeds and flowers.
a)
Most successful group of plants because insects (bees) carry
their pollen from flower to flower.
b)
Seeds are enclosed in a fruit that can be carried from place to
place.
c)
Includes most plants that we see.
Examples: grasses, flowers, fruit-bearing trees
Plant Processes:
1) Tropism - a change in the growth of a plant in response to a stimuli. Plant growth in response to
light is called phototropism. Plant growth in response to gravity is called gravitropism.
2) Photosynthesis – takes place in the chloroplast using sunlight energy captured by the green
pigment called chlorophyll. Reactants: carbon dioxide, water, sunlight. Products: glucose and
oxygen.
3) Cellular Respiration: Glucose and oxygen are broken down in the mitochondria to release stored
energy in the form of ATP. Water and carbon dioxide are waste products.
