The Plant Kingdom4 General
Characteristics:
3) They have chloroplasts2) Plants make their own food byphotosynthesis
1) Multi-celled organisms
organelle wherephotosynthesis
takes placechloroplasts-
theyre green because they have chlorophyll
the chemical that gives plants their green color
Chlorophyll-
traps light energy for photosynthesis

4 General Characteristics Contd
4) Plant cells havecell walls (animal cells do not)
stiff cell walls give structure to each cell
also supports the plant
made of cellulose
have holes through which cells sharecytoplasm & pass nutrients sugars, water, and
hormones

Photosynthesis:
releases oxygen
Process in which plants use water, carbondioxide, and energy from the sun to make food
Photosynthesis-
only occurs in the chloroplasts
Prefixphotomeans:
Light
Root word synthesismeans:
to make

Vascular Plants
Vascular Plants-
plants that have tube-like cells
in their roots, stems, & leavesthat carry H2O and nutrients
Vascular comes from
the Latin wordvasculumwhichmeans vessel
roots, stems, and leaves of a plant are all
called organs
they lose their leaves like a pet sheds

Vascular Plants: 3 organs and their jobs
Vascular Plant Organs:( roots, stems, & leaves)
ROOTS-anchors the plant into the ground
STEMS-
LEAVES-
place where all of the chloroplasts are located
takes in H2O & nutrients directly from the soil
carry water to all parts of the plant
holds the leaves up to the sunlight

Vascular Plants: 2 Types of Tubes
tube-like cells that carry water & dissolved
minerals from the roots to the leaves
tube-like cells that carry food, which is
made in the leaves, to all partsof the plant
each one has a specific function (job)
a) xylem b) phloem
vascular plants have 2 different types oftube-like structures inside them
think of tiny pipes...like a plumbing system

Vascular Plants: Two Main Groups
1) seedless plants
Vascular plant that DO NOThave seedsEx: ferns
2) seed plants
Vascular plant that haveseeds for reproduction
Ex: conifers & flowering plants

Vascular Plants: Seedless (ferns)
Ferns- seedless plants
usually grow in moist shady areas
they have adapted to grow in other environments:
stem stores the food & water
-aquatic (water)-dry climates-tropical regions
water horn fern
tropical fern
typical fern

Vascular Plants: Seedless (ferns)
The Fern Leaf
divided into tiny leaflets that look feathery
loses leaves at the end of each growing season
ferns are classified by their leaves
reproduce by spores formed onthe underside of the leaf
The Fern Reproduction
the cases that hold the spores
look like brown and orange spots

Vascular Plants: Seedless (ferns)
4 Parts of a Fern:
rhizoid- an underground stem thatanchored by the roots
roots- anchor the fern
Frond- full grown leaves that stand vertically
Fiddlehead- tightly coiled new leaves

Vascular Plants: Seed Plants (conifers)
Conifer-
2 main parts :
embryo-An organism that contains a new youngplant and stored food in its earlieststage of birth
seed-
A plant embryo that contains a newyoung plant and stored food
surrounded by a protective coat
a type of seed plant that
produces its seeds insidea cone

Vascular Plants: Seed Plants (conifers)
Evergreens-
they lose their leaves like a pet sheds
a type of conifer that keeps itsleaves all year long
example: pine, spruce, & fir trees
some lose their leaves in the fall only such as:
larch, dawn redwood, & bald cypress
(not all at the same time)
