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

cells walls

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

What process is illustrated here?

6CO2+ 6H2O + light energy = C6H12O6+ 6O2

2 Main Types of Plants

2) Nonvascular Plants

1) Vascular Plants

PLANTS

Vascular Nonvascular

broken into 2 more subgroups called:a) seedless plants

b) seed plants

notbroken into subgroups

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


12/26

12

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


13/26

13

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

PLANTS

Seedless PlantsSeed PlantsVascular Nonvascular

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


17/26

17

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


18/26

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

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

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)

5 important facts about conifers

1) of the worlds lumber is from conifers

2) provide almost all of the worlds paper

3) source of turpentine's, disinfectants, and fuel

4) Provides food for many animals

5) Provides shelter for many animals
