The Plant Kingdom
4 General Characteristics:
3) They have chloroplasts2) Plants make their own food by photosynthesis
1) Multi-celled organisms
organelle where
photosynthesis takes place
chloroplasts-
•they’re green because they have chlorophyll
•the chemical that gives plants their green color
Chlorophyll-
•traps light energy for photosynthesis

4 General Characteristics Cont’d
4) Plant cells have cell 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 share cytoplasm & pass nutrients sugars, water, and hormones
cells walls

Photosynthesis::
•releases oxygenreleases oxygen
Process in which plants use water, carbon Process in which plants use water, carbon dioxide, and energy from the sun to make dioxide, and energy from the sun to make foodfood
PhotosynthesisPhotosynthesis - -
•only occurs in the chloroplastsonly occurs in the chloroplasts
Prefix photo means:LightRoot word synthesis means:
to make

What process is illustrated here?
6CO2 + 6H2O + light energy = C6H12O6 + 6O2

Vascular Plants
Vascular Plants-plants that have tube-like cells in their roots, stems, & leaves that carry H2O and nutrients•Vascular comes
from the Latin word “vasculum” which means “vessel”
•roots, stems, and leaves of a plant are all called organs
•they lose their leaves like a pet sheds
![Page 12: The Plant Kingdom](https://reader034.vdocument.in/reader034/viewer/2022042901/56813b85550346895da4af2e/html5/thumbnails/12.jpg)

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 tube-like cells that carry water & dissolved minerals from the minerals from the roots to the leavesroots to the leaves
tube-liketube-like cells that carry cells that carry foodfood, which is , which is made in the leaves, to made in the leaves, to all partsall parts of the of the plantplant
each one has a specific function (job)a) xylem b) phloem
vascular plants have 2 different types of tube-like structures inside them
think of tiny pipes...like a plumbing system

Vascular Plants: Two Main Groups
1) seedless plants•Vascular plant that DO NOT have seedsEx: ferns
2) seed plants•Vascular plant that have seeds for reproductionEx: 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 on the 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 that anchored 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
young plant and stored food in its earliest stage of birth
seed-A plant embryo that contains a new young plant and stored food surrounded by a protective coat
a type of seed plant that produces its seeds inside a cone

Vascular Plants: Seed Plants (conifers)Evergreens-
•they lose their leaves like a pet sheds
a type of conifer that keeps its leaves 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)

Vascular Plants: Seed Plants (conifers)5 important facts about conifers
1) ¾ of the worlds lumber is from conifers2) provide almost all of the worlds
paper3) source of turpentine's, disinfectants, and fuel
4) Provides food for many animals
5) Provides shelter for many animals
