KINGDOM PLANTAE
WHAT ARE THE CHARACTERISTICS OF PLANTS?
2
ALL PLANTS
ARE MULTI-CELLULAR Made of more than one cell.
ARE MACROSCOPIC Can be seen with the naked eye.
3
PLANT CELLS
WHAT TYPE OF CELLS ARE PLANT CELLS?
EUKARYOTIC
Nucleus
4
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
5
PLANT CELLS
Vacuole
Vacuoles are membrane-bound spaces used for
temporary storage of materials.
6
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
7
ALL PLANTS
are
AUTOTROPHS
(also called producers) because they can produce
their own food.
8
PHOTOSYNTHESIS
6CO2 6H2O?C6H12O6 6O2
9
There are a few plants that are also
heterotrophs They attract, capture, and kill
organisms (mostly insects) and absorb the
nutrients from their prey.
10
WHY ARE PLANTS IMPORTANT TO HETEROTROPHS?
oxygen
11
Many medicines are made from plant materials.
Without plants, we wouldnt have chocolate, tea,
or coffee
12
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
13
PLANTS ARE DIVERSE
Some plants are terrestrial
Some plants are aquatic
14
PLANTS ARE DIVERSE
Plants vary in size
Rafflesia
Redwood trees Can get up to 350 ft tall
Duckweed Can be around 1 mm
Amorphophallus titanum
15
PLANTS ARE DIVERSE
LIFESPAN
Brassica rapa 40 days
Bristlecone Pine 5000 years
16
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
