PlantsPlants, 5 kingdoms
The Monera KingdomThe Monera Kingdom contains mainly bacteria. Bacteria are unicellular and
prokaryotic.
Bacteria are found on land, water, air, and inside other living organisms.
You need a microscope to see bacteria because they are so tiny. They can also
reproduce very quickly. In just a few hours, hundreds of bacteria can become
millions!
Lets answer some questions.
1. What types of organisms belong to the Monera Kingdom?
2. Name four places where Monera organisms can be found.
3. Are these sentences True or False? Correct the false ones.
a) Bacteria form part of the Monera Kingdom.
b) Bacteria have a nucleus.
c) Bacteria can be seen with the naked eye.
d) Bacteria are unicellular.
4. Write a short paragraph in your notebook explaining the Monera Kingdom using
the words: microscopic, unicellular, bacteria
Protoctista● Eukaryotic cells
● Unicellular (protozoa, etc...) and
multicellular (large algae, like seaweed).
● Protozoa are heterotrophic. Algae are
autotrophic.
Algae
• Unicellular algae: found in lakes and rivers. Have tails called flagella which help them to move about.
• Multicellular algae: seaweed and kelp, form forests underwater, sheltering and feeding marine animals.
Algae● Protoctista● Unicellular & Multicellular● Microscopic, or 50 meters in size (seaweed)● Autotrophic● Found in water, trees, and some rocks.
Fungi● Eukaryotic cells.
● Membranes have a cell wall.
● Unicellular (yeast), and multicellular (moulds
and mushrooms). Don't form tissues.
● Heterotrophic nutrition.
Lets answer some questions.
1. List three ways that fungi are beneficial to us
2. Which of the following are unicellular?
a. yeast b. mould c. mushrooms
3. Why is it important to be an expert in mushrooms when picking
them?
Parts of plantsWhat do they do?
The roots fix the plant to the ground. Roots can be different shapes; they usually branch
out, and there are tiny hairs on the ends of these branches, called root hairs. These root
hairs allow water and minerals from the soil to enter the plant.

ROOTSHold the plant in place
Have hairs called root hairs
Root hairs absorb water and nutrients
The stem is usually above the surface of the soil and holds up the rest of the plant. A stem may have branches
or it may not. Stems can be thin, green and flexible. When they are thick and woody, they are called trunks.

Parts of plantsWhat do they do?

May have branches
Tree stems are called trunks.
The leaves are normally green, flat and have veins running through them. They join to the
stem of the plant by the stalk (petiole). Leaves have two sides: upper and lower.
The leaves
Parts of plantsWhat do they do?

Upper side is bright green and shiny
Lower side has
The vessels are tube-shaped cells which run through the inside of the root, stem, branches
and the veins of the leaves. Water and other substances flow through them.
