Everyday Botany & Plant Physiology
botany:
the study of plants
physiology:
study of the
mechanisms of living things
Plant Review
What makes plants green?
From where do plants get their energy?
pinnate
palmate
Leaf Venation
branching venation
parallel
venation
Simple vs Compound
http://namethatplant.blogspot.com/2009_03_01_archive.html
Stomata
use of mineral nutrient solutions instead of soil
easier to control
Petals in multiples of four or five
Leaves palmate or pinnate venation
Stem vascular bundles are organized
Roots are taproots
Petals in multiples of three
Leaves have parallel venation
Stem vascular bundles are random
Roots are fibrous
see page 127
ROOT Gravitropism
sedimentation of amyloplasts allows plant to sense gravity
Phototropism
Gravitropism
STEM Gravitropism
tropism
: movement in response to external stimulus
Sensing of gravity sends roots down
Benefit: Roots go toward water!
procedure 9.2
(just observe)
Sensing of gravity
sends stems up
Benefit: Stems will go toward light source
directed growth in
response to light
Procedure 9.1
measure angle change of stem in response in light over time with a protractor
Procedure 9.3
(just observe)
The world is...
GREEN!
Plant Diversity
Angiosperms
Gymnosperms
eg. pine trees
eg. Tilia
(basswood)
Monocots
Dicots
cotyledons
"seed leaves" produced by the embryo
serves as food to embryo during seed dormancy
may become the first leaf/leaves upon germination
page 137: dissect a peanut
Further Categorizing Angiosperms
flowering plants
mono = one cotyledons
di = two cotyledons
eg. corn
eg. bean
Find 3 examples of each from
plants on display
support
xylem: water transport
phloem: nutrient transport
including one of our biologically important molecules... sugar!
new stems and leaves
page 132: celery activity
Monocot vs Dicot
cluster of xylem and phloem cells
transport water (xylem) and nutrients (phloem)
page 132 activity
(page 127)
stem vascular bundles
Vascular Bundles
scattered
ringed
We Eat Modified Stems!
(page 126 & 131)
stolon
eg. strawberries
bulb
eg. onion
tuber
eg. potato
rhizome
eg.. ginger
Sweet Potato
Parsnip
Beets
Radish
Turnip
eg. carrots
taproot
monocots
fibrous
adventitious
dicots
eg. grasses
"prop roots"
Leaf Characteristics
(page 128)
Leaf Arrangement
Seeds
Fruits
ripened ovary containing seeds
fleshy and juicy
examples
apple
tomato
Dispersal
fertilized and ripened ovules of a plant
contain nutrients for embyro
(page 137: list 3 types)
(monocots)
(dicots)
(page 130, but use directions on table)
pores for gas exchange
two guard cells control
if open or closed
stomata under the microscope
Flowers
Purpose of flowers?
To look pretty for humans?
Flower Anatomy
(page 134: dissect a flower)
Monocots vs Dicots
petals in patterns of 3
petals in patterns of 4 or 5
POLLINATION!
pollinators unknowningly carry pollen to other plants
pollinators are after a sugary food source (nectar)
many types of pollinators, including bees, butterflies, bats and hummingbirds
pollen grains: male gametes
contains ovules: eggs (female gametes)
(after fertilization, develops into a seed)
dry
acorn
wheat
Plants are beneficial
to humans
food source
enjoyment
Stop and smell the roses.
Eat your broccoli!
medicinal
Catnip is for humans too!
What makes all these plants different?
GENES
within DNA
Etiolation
Procedure 9.6 (page 142): etiolated plants are in the incubator, other plants on windowsill
(skip Procedure 9.4 and 9.5)
etiolation:
when seedlings are grown in insufficient light the symptoms are characterized by...
(do procedure to find out!)
Leaf Adaptations
cacti have
leaf spikes that serve to minimize
water loss through stomata
other succulents, such as
moonstone have thick
epidermis to prevent
water loss through stomata
venus fly traps use
their leaves to capture
prey
Dissect A Peanut!
(page 137)
Within the hard shell
of the peanut fruit,
are peanut seeds
Find all parts
You will be asked to
name each part
on lab practical!
cotyledon
Recognizing Poison Ivy
"leaves of three, let it be"
also, red stem near leaves

& 126
page 131-132
page 128-131
page 129
page 134-135
annual: survive one growing season
perennial: survive multiple
growing seasons
deciduous: lose leaves
every season
Other terms to know
page 135
page 136-137
page 136
wind
water
animals
attachment to animal fur
expulsion
