Basic Anatomy
The Leaf
1. Blade=where photosynthesis takes place
2. Vein=carries water, minerals, & sugar
through blade.
3. Petiole=connects the leaf to the stem;
transports fluids
A.
Blade
Petiole
Vein
The leaf cross-section
3 parts:
1. Cuticle= waxy covering; prevents water loss
2. Stomata= allows gas & water vapor in & out
( the opening )
3. Guard Cell= opens & closes stomata.
( surrounds the stomata )
*Paste picture into notes.
A closer look….
Draw &
Label
Transpiration
= loss of water through the stomata.
Basic Anatomy
B. The Stem
3 types of tissue:
1) Dermal= outer layer; covers & protects
2) Ground= storage, support, &
photosynthesis.
3) Vascular = transport water & nutrients
a. Xylem
b. Phloem
Xylem
They are dead cells; they transport water &
minerals salts .
* Dead xylem makes rings in trees.
Phloem
They are living cells; transport “food” ( the
sugar produced by plants )
Basic Anatomy
3) The Root
a. Absorb water & minerals
b. Anchors plants
c. Some store food
Roots
Root tip= site of maximum absorption of
water & mineral salts
Root hairs: they increase surface area for
absorption.
Root Cap
It covers & protects the root as it grows into
the Earth.
Root Types
Tap root= single ( main ) root; deep
strong anchor for plant; gets ground
water.
Example: Carrots, beets
1)
Root Types
Fibrous root= many primary roots; found in
upper soil; cover wide area
Examples: Grass, ferns, banana, onion
Can you tell the difference?
Banyan Trees
 Common
in Hawaii but grow in a very
uncommon way: the roots grow in
reverse, reaching down to the ground
from the branches above.
 Roots are considered
"aerial prop roots"
Plant Drawing Activity

a. blade
e. tap root or

Notes # 2
Objectives
1)
I will compare and contrast monocot
and dicot plants by completing my 3-5
complete sentence summary.
Plant Classification
Plants are classified by their reproductive
systems.
1. Without seeds- Sporophytes
2. With seeds- Spermatophytes
Angiosperms
1)
2)
3)
Flowering plants
Bear seeds within ovaries which surround
& protect the seed.
Two types:
a. Monocot
b. Dicot
Monocot & Dicot
Monocot
= one cotyledon
*Latin Root: Mono=one
Dicot
= two cotyledon
*Latin root: Di=two
Monocot
1)
2)
3)
4)
5)
Single cotyledon- seed leaf
Parallel veins
Flower petals in multiples of 3
Vascular tissue scattered throughout the stem
Fibrous root
Dicots
1)
2)
3)
4)
5)
Two cotyledon leaves
Branched veins
Flower petals in multiples of 4 or 5
Vascular tissue arranged in a ring
Taproots
Angiosperms life cycles
1)
2)
3)
Annuals = one growing season
Biennials = two growing seasons
Perennial= live many years
Morning

Japanese
boxglove
Azaleas
Adaptations in plants
Tropism= the growth of a plant to an
external stimulus such as
1. light ( phototropism )
2. touch ( thigmatropism )
3. gravity ( geotropism )
Greek root TROPE= “ a turning “
Phototropism
= Growth towards light
Thigmatropism
= growth towards touch or a solid object
Venus Fly Trap
Twining Vine
Thigmatropism
The coiling
is caused
by the
sides of
the vine
growing at
different
rates.
Geotropism
= Growth towards gravity
No matter which way you turn the
seed, the root will respond to gravity
and grow toward the Earth
Adaptations
1.
Cacti- needle like leaves to prevent
water loss & protection
Adaptations
1.
2.
Venus fly trap- trap insects b/c it lives in
nutrient depleted soil
Pitcher plant- leaves made to trap
insects.
Leaf Cross-Section Activity
1) Draw a cross-section of a leaf
2) Label
a. Cuticle
b. Guard Cell
c. Stomata

Notes # 3
Objectives
1)
I will identify parts of a flower by filling in
the picture of a flower in my notes.
Turgor Pressure video
Turgor Pressure
= pressure exerted on the plant’s cell wall
by water passing INTO the cell by osmosis.
*Hypotonic
*Hypertonic
Reproduction of Plants
1) Spores = reproductive organ that requires
water to be transported.
Example: spores on a fern
Reproduction of Plants
2) Seeds = organ that contains an embryo,
food supply, & protective coat.
Remember: Cotyledon= stores or
absorbs food for the developing
embryo.
Reproduction in Plants
3) Fruit = houses the seeds & aids in dispersal
by wind, water, insects, & other organisms
a. one seed; ex=peach
b. several seeds; ex= strawberry
c. some are not edible; ex= walnut
shell or coconut shell
Paste Flower sheet in your
notebook
The Flower
Flowers include both male and female
reproductive organs.
The Flower
Male Organs = called the “Stamen”
1. Anther = tip of the stamen;
produces pollen
2. Filament = Stalk of the anther
The Flower
Female Organs = called the “Pistil”
1. Stigma = receives pollen
2. Style = connects stigma to ovary
3. Ovary = protects ovule; becomes
the fruit after fertilization
4. Ovule = develops into the seed
The Flower
There are two parts that are neither male
nor female
1. Petal = colorful; attracts insects
2. Sepal = protective cover for flower bud

Notes # 4
Objectives
1)
I will compare and contrast
photosynthesis and cellular respiration by
completing my 3-5 complete sentence
summary.
Photosynthesis
= process of converting light energy into
chemical energy.
** The most important chemical reaction on
our planet!
Photosynthesis
1)Energy is stored as sugar ( glucose )
2)Occurs in plants & some algae
3)Takes place in the chloroplast
How does it happen?
1)Plants capture light energy & use to make
glucose. ( sugar )
2)Sunlight provides energy to change the
carbon dioxide & water into glucose
3)Oxygen is released
How does it happen?
4) CO2 enters leaf through holes called
stomata.
5) CO2 combines w/ stored energy in
chloroplasts to make glucose
6) The sugar moves through tubes in leaf to
the roots, stems, and fruits of plants.
7) Some sugar is used right away & some is
stored as starch
Photosynthesis
Photosynthetic equation
Photosynthesis Equation
Reactants
Products
Six molecules of carbon dioxide
react with six molecules of water
to form 1 molecule of glucose
and six molecules of oxygen.
*Occurs in the
Chloroplast
Why is this important to us?
1)The oxygen released during
photosynthesis is necessary for all living
things.
2) We cannot make our own food (glucose,
energy), we get food from plants.
3) Plants are first step in food chain.
Cellular Respiration
= release of chemical energy (glucose) for
use by cells.
* ATP= energy
Cellular Respiration Equation
*Occurs in the
mitochondria
Reactants
Products
Why is it important?
1)
2)
All living things go through cellular
respiration.
Plants need the CO2 released by
organisms to complete photosynthesis.
Paste this handout in your
notes.
ENERGY CONVERSIONS
1)All organisms produce ATP by releasing
energy stored in glucose
2)Plants make ATP during photosynthesis.
Photosynthesis & Cellular
Respiration Worksheet
Complete the worksheet for a grade!
Avid Thinking StrategyGraphic Presentation
-Develop an illustration that will tell the
world about photosynthesis & cellular
respiration.
1) Centerpiece must be a slogan or phrase
2) Surrounding artwork=minimum of 4 color
3) End with a 4 sentence explanation of
how the artwork represents the topic.
Graphic Presentation Example
Slogan: Photosynthesis:
The most important
process on Earth!
Explanation: Photosynthesis is the most important process on
Earth. Plants give off essential oxygen for all living things.
Plants are the start of every food chain. Without plants, most
organisms would die from starvation or suffocation.
