2. Yes No Do you agree with the statement? 1
Plants are multicellular organisms.
Yes No

3. Yes No Do you agree with the statement? 2
Vascular means that nutrients are carried
throughout a plant by special tubes.
Yes No

4. Yes No Do you agree with the statement? 3
Conifers are different from ferns in that
conifers do not have leaves.
Yes No

5. Yes No Do you agree with the statement? 4
All organisms are classified either as
plants or as animals.
Yes No

6. Qualities of Plants
Plants are different from animals; they use sunlight, water, 
and carbon dioxide to make their own food and have roots and 
leaves.
Many plants are vascular, which means they have special 
tubes that carry food and water to all parts of the plant.
Four common types of plant phyla are mosses, ferns, 
conifers, and flowering plants.

Qualities of Plants

7. Mosses Conifers Ferns Flowering Plants
Mosses grow on trees or in 
shallow streams and are very 
small.
Mosses are not vascular and 
have tiny parts that look
like leaves.
They don’t have
flowers or seeds.
Pine, fir, and spruce trees are all 
conifers that have special leaves 
called needles.
Conifers are vascular plants and 
reproduce using cones and seeds.
Ferns
Flowering Plants
Most ferns have leaves that look like 
feathers and are vascular plants, which 
can grow larger than nonvascular 
plants.
Vascular plants have tubes that carry 
food to parts of the plant that are high 
off the ground.
Mosses and ferns use 
spores to reproduce, which 
are tiny cells that can grow into plants.
There are about 230,000 
species of flowering plants they 
are all vascular.
These plants use their flowers’ 
seeds to reproduce.
Mosses, ferns, and conifers 
don’t produce flowers.

8. Neither Plant Nor Animal
Many organisms do not belong in either the plant or 
animal kingdoms and some of these organisms can 
move on their own like animals, but they make their own 
food like plants.
Some organisms are made of one cell and these can 
only be seen through a microscope.
Some of these microscopic organisms can cause 
disease and others can be helpful.
Like plants and animals, all these organisms need 
food, water, and a way to remove waste. Many also 
need carbon dioxide or oxygen.

9. Debates in Classifying
The classification system has changed over the years because scientists 
find new organisms.
One classification system used today has six kingdoms, which include 
plants, animals, fungi, protists, eubacteria, and archaebacteria.
Fungi, such as mushrooms, are not plants because they cannot make their 
own food because they absorb food from the material they grow on. Yeast are 
single-celled fungi and to reproduce, each cell divides into two cells.
Protists such as algae are single cells and are food for many animals. Some 
live in the digestive systems of some animals, like termites and cows. They 
help these animals digest plants they eat.
Eubacteria are single cells and can have many different shapes. Some have 
tails that move them through water.
Archaebacteria are single cells and can survive in environments that are 
deadly for most other organisms. They can live in hot acid springs or in very 
salty water.

11. TextQuest Answer questions in your Science Journal.
1. How would you classify a plant that has seeds, is 
vascular, and has needle-like leaves?
2. How do protists help some animals?
3. How are the needs of single-celled organisms 
similar to the needs of plants or animals?
4. Compare the fungi and protist kingdom.
