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
First paragraph
pg. 22
Mosses
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.
Ferns
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.
Conifers
Pine, fir, and spruce trees are all conifers that
have special leaves called needles.
Conifers are vascular plants and reproduce using
cones and seeds.
Flowering 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.
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.

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.

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.
