PLANTAE
WHAT ARE THE CHARACTERISTICS OF
PLANTS?
ALL PLANTS:
ARE MULTI-CELLULAR
Made of more than one cell.
ARE MACROSCOPIC
Can be seen with the naked eye.
PLANT CELLS
WHAT TYPE OF CELLS
ARE PLANT CELLS?
EUKARYOTIC
Nucleus
PLANT CELLS
Cell Wall
The cell wall is made primarily
of CELLULOSE, a complex
carbohydrate.
• Keeps the cell from rupturing
• Prevents water loss
• Shape and protection
PLANT CELLS
Vacuole
Vacuoles are membrane-bound
spaces used for temporary
storage of materials.
PLANT CELLS
Chloroplast
The chloroplasts are cell organelles
that capture light energy and produce
food (glucose) to store.
They contain the photosynthetic
pigment, CHLOROPHYLL. This
primary photoreceptor absorbs the
light energy.
CHLOROS- “green”, PHYLLON- “leaf”
Chloroplast
Granum in Latin literally means
“stack of coins”.
Thylakoid: derived from Greek
word thylakos, meaning “sac”.
ALL PLANTS:
are
(also called producers) because they
can produce their own food.
6CO2 + 6H2O→C6H12O6 + 6O2
There are a few plants that are also heterotrophs:
They attract, capture, and kill organisms (mostly insects)
and absorb the nutrients from their prey.

WHY ARE PLANTS IMPORTANT TO
HETEROTROPHS?
oxygen
Many medicines
are made from
plant materials.
Without plants, we
wouldn’t have
chocolate, tea, or
coffee
plant reproduction
All plants reproduce sexually.
Some can also reproduce asexually.
ALTERNATION
OF
GENERATIONS
During their lives, all plants alternate between:
a haploid (half the chromosomes) gametophyte (produces gametes) stage
and
a diploid (complete set of chromosomes) sporophyte (produces spores) stage
PLANTS ARE DIVERSE
Some plants are terrestrial
Some plants are aquatic
PLANTS ARE DIVERSE
Plants vary in size
Rafflesia
Duckweed
CanAmorphophallus
be around 1 mmtitanum
Redwood trees
Can get up to 350 ft tall
PLANTS ARE DIVERSE
LIFESPAN
Brassica rapa: 40 days
Bristlecone Pine: 5000 years
Plants are believed to have evolved from
green algae.
Green algae and plants both have: cell walls made of cellulose
contain chlorophyll
store food in the form of starch
KINGDOM PLANTAE
Contains:
12 Phyla or Divisions
There are 300,000 species of plants!
1.Plants are…
a.Unicellular prokaryotic heterotrophs
b.Multicellular prokaryotic heterotrophs
c.Unicellular eukaryotic photoautotrophs
d.Multicellular eukaryotic photoautotrophs
2.Most plants fill the ____________________
trophic level in the food web.
a. Decomposer
b. Producer
c. Primary consumer
d. Secondary consumer
3.The cell walls of plant cells contain
a.Peptidoglycan
b.Glucose
c.Wax
d.Cellulose
4.Which of the following is an indirect way in
which humans depend upon plants?
a. We use plants for food
b. We depend upon plants for shelter and
building materials
c. We eat herbivores
d. We use plants for medicinal reasons
because of their curative value
5.
The food which plants manufacture with the
help of the sun’s energy is…
a. Simple glucose
b. Protein
c. Peptidoglycan
d. cellulose
9.Why are plants eukaryotes?
a. Because their cells are complex and contain
membrane-bound organelles
b. Because their cells are simple and do not
contain a true nucleus or membrane-bound
organelles
c. Because they contain chlorophyll which
helps them use the sun’s energy to make
food.
d. Because they are multicellular
