Learning
Goal


Understand the characteristics of
plants
Determine the difference
between coniferous and
deciduous trees.
Seeds contain new plants





A seed is the start of a
new plant
The have different
shapes, sizes and colors
Flowers make seeds
Covered in a seed coat
to protect and keeps
tiny leaves and root
inside
Contains food for the
new plant

seeds travel




seeds stick to socks
stick to animal fur
seeds blow in the wind
seeds to grow need:




Soil
Water
Sunlight
Seeds are planted to
grow in the gardens
Plants’ Stages

Stage 1


Stage 2



Germ grows inside seed
Plant shoots up from
germ
Roots develop down
from germ
Stage 3


Leaves develop
Roots grow

Stage 4


Flower buds grow
Stage 5

Full-grown plant

Leaves, stems,
flowers and roots
Plant Parts

Stems




Have little tubes that carry
water and food to the rest of
the plant
Hold up leaves and flowers of
the plant
Grass, flowers, and vines have
soft stems
Roots



Collect water and minerals
for the plant
They hold the plant in the
ground
Some plants store food in the
roots

Leaves


Make food for the plant
Green leaves + air + sunlight = plant food
 Flowers
Flowers are many sizes, colors, and
shapes
Make seeds
The seeds grow into new plants

How Does A Tree Get Its Name?
11
Classification

Classification is the grouping of things
according to how they are alike or different.

We group things everyday.

Grouping things makes it easier to remember.
12
Did You Know A Tree Has A Name?
Scientist give trees their very own
two-part scientific name.
They are given a genus name and
a species name.
13
The Genus Name
The Genus name tells what family they belong
to.
Just like your last name tells us what family
you belong to.
The Genus name always starts with a Capital
Letter.
14
The Species Name
The Species Name is the individual name.
Just like your first name tells us who you are in
your family.
It always starts with a small letter.
15
How Do I Know It’s A Scientific Name?
Scientists use a special type of writing. Both
names are always written in italics.
Quercus virginiana
Oak Tree-Common Name
16
A Key to Common Trees In Ontario
We use the leaf, seed and bark as the primary
features to identify trees.
17
Let’s Look At A Tree’s Shape


There are 3 basic types of trees.
It is useful to look at the general shape of the
tree as a starting point to identify the type of
tree you are looking at.
18
Three Basic Groups of Trees

palms, coniferous, and deciduous.
19
No leaves, Oh No!
Coniferous trees have leaves that are
different from a Deciduous tree. They have
seeds in cones. They do not lose their
leaves in the autumn. They stay green
year round.
They have needles and scales instead.
The needles and scales are sticky and have
a scent. Don’t eat them because they are
poisonous!
20
Is it a CONIFER or a DECIDUOUS
tree?


CONIFERS are trees & shrubs with needles: pine,
spruce, fir, cedar, juniper, and tamarack. They retain
their needles year-round (except for Tamarack).
DECIDUOUS trees & shrubs are all others. The
leaves of DECIDUOUS trees & shrubs die every
autumn and are usually shed (some species retain
some or all of their dead leaves until the following
spring).
22
Deciduous Trees

Deciduous trees shed their leaves in the
autumn. Many deciduous trees are broadleaved trees. Broad-leaved trees have broad,
flat leaves.

Did you know that????

There are four main forest regions in Ontario: Boreal, Boreal Barrens, Great Lakes
St. Lawrence and Carolinian.
58.0 million hectares of forested land out of a total 106.8 million hectares of land
and water.
88% of the inventoried, productive forest land is publicly owned; 11% is private
land, one-half of which is in northern Ontario, and the remaining 1% is federal land.
There are about a quarter of a million lakes, thousands of rivers and streams, and
large portions of the Great Lakes, which hold nearly 20% of the world's fresh water.
Approximately one-half of the people directly and indirectly dependent on the
forest industry live in southern Ontario.
Ontario's forests are home to over 3, 600 species of plants and animals, of which 21
plants and 9 animals are considered endangered or threatened.
About 40% of the species at risk in Canada occurs in this province, and the majority
of those are from southern Ontario.
Ontario's forests and waters are the main recreational areas for both residents and
tourists.
Ontario's forest industry produces $11 billion worth of products that contribute over
$2 billion to Ontario's balance of trade or $200 for every person annually.
The recreational fisheries on Ontario waters provide more than $2.3 billion in added
value to the economy.

Trees keep our air supply fresh by absorbing carbon dioxide and producing oxygen
In one year, a single tree can absorb as much carbon as is produced by a car driven 26, 000
miles
Trees provide shade and shelter, reducing yearly heating and cooling costs by $2.1 billion
Trees lower air temperature by evaporating water into their leaves
The average tree in the metropolitan area survives only eight years
A tree does not reach its most productive stage of carbon storage for about ten years
Trees cut down noise pollution by acting as sound barriers
Tree roots stabilize the soil and prevent erosion
Trees improve water quality by slowing and filtering rain water as well as reduce storm run
off and the possibility of flooding
Trees provide food and shelter for wildlife
Trees located along the streets act as a glare and reflection control
The death of one 70 year old tree would return over three tons of carbon to the atmosphere
Trees renew our air supply by absorbing carbon dioxide and producing oxygen
Two mature trees can provide enough oxygen for a family of four
One tree produces nearly 260 pounds of oxygen each year
One acre of trees removes up to 2.6 tons of carbon dioxide each year
Shade trees can make buildings up to twenty degrees cooler in the summer
