The Plant Kingdom
Name 4 characteristics of plants.
Characteristics of plants:
1. autotrophs – use photosynthesis
2. eukaryotes
3. multicellular – cells form tissues
4. cells contain cell walls
Define photosynthesis.
Photosynthesis is a plant’s foodmaking process.
What 3 things does a plant need for
photosynthesis? What does the plant
produce in the process?
Plants need sunlight, nutrients and
CO2 and produce O2.
Define tissues.
Tissues are groups of similar cells
that perform a specific function in
an organism.
Name 2 functions of the cell wall.
Cell walls:
1. separate the cell from the outside
environment
2. contain cellulose which makes
the cell rigid
What is a chloroplast?
A chloroplast is where the plant’s
food is made.
What is the function of the plant’s
vacuole?
The vacuole stores water, food, or
waste.
Name the 5 adaptations plants have
made for living on land.
Adaptations for living on land:
1. obtain water and nutrients from
soil through their roots
2. retain water – have a cuticle that
helps reduce water loss
3. transport water and nutrients
through vascular tissues
4. support their bodies
5. reproduce in dry environments
What are the 2 types of plants?
Describe their characteristics.
Types of plants:
1. non-vascular
• short
• no roots
• live in damp, shady places
• get nutrients directly from their
environment
• NO vascular tissue
• Examples: moss, liverwort
2. vascular
• can live in dry environments
• contain vascular tissue
• can grow tall
• Examples: gymnosperms,
angiosperms
Define chlorophyll.
Chlorophyll is a green pigment found
in the chloroplasts of plants, algae,
and some bacteria.
What evidence supports the idea
that ancient green algae were the
ancestors of today’s land plants?
Fossil records and the same forms of
chlorophyll found in both green algae
and today’s land plants indicate that
they are related.
