Presentation Transcript

Slide1

Introduction to Plant ScienceSlide2

Horticulture

Word first used in 1600

s

Comes from two Latin words

Hortus

Garden

Cultura

Cultivation

Horticulture means

cultivated garden

or

culture of garden plants

NOW

MANY more “branches”…. TPS Slide3

Life Sciences

Biology

is the branch of science that deals with both plant and animal organisms and life processes.

Zoology is the part of biology that deals with animals.

Botany

is the part of biology that deals with plants.Slide4

Horticulture

The science and practice of growing, processing and marketing fruits, vegetables, and ornamental plants.Slide5

Agronomy

The science and practice of growing field crops such as cotton, wheat, tobacco, corn and soybeans.Slide6

Branches of Horticulture

Olericulture

Study

and growing of vegetables

Pomology

Study

and growing of fruits and nuts

Viticulture – Producing grapes and grape productsSlide7

Branches of Horticulture

Viticulture

The growing and study of grapes or vines.

Floriculture

The growing and study of flowers.Slide8

Branches of Horticulture

Greenhouse Management

The growing and study of plants in greenhouses.

Turfgrass

Management

The growing and study of

turfgrasses

. This includes home, municipal, and commercial lawns; sports turf maintenance; highway rights-of-way; and seed and sod production.Slide9

Branches of Horticulture

Nursery Management

The growing and study of trees and shrubs that are produced primarily for landscape purposes.

Arboriculture

The growing and study of trees.

Known as

silviculture

in forestry.Synonymous with urban forestry.Slide10

Branches of Horticulture

Landscape Horticulture

The application of design and horticultural principles to placement and care of plants in the landscape

.

Interiorscaping

The application of design and horticultural principles to placement and care of plants in indoor environments.Slide11

Branches of Horticulture

Horticultural Therapy

The use of horticultural plants and methods as therapeutic tools with disabled and disadvantaged people.Slide12

Discuss with the people around you which branch of horticulture would be the best fit for you and why – be able to provide evidence to prove your point Slide13

What is the history of taxonomic classification?

Taxonomy

is the science

of identifying and naming organisms

A. The Greeks made the first attempts at taxonomy nearly 2,000 years ago, but their efforts were limited, with no definite system of naming living things.Slide14

Why are plants classified and named?

Some plants have more than one common name

Ex: Snake Plant, Mother in Laws Tongue

Some common names refer to more than one plant

Ex: Ivy

Easier for all people to identify

and recognizeSlide15

Binomial System of Naming Plants

Traditional scientific names were too long… ex: cat nip =

Nepeta

floribus

interrupte

spicatis pedunculatisFamous Swedish Botanist, Linnaeus simplified this by developing binomial (two name) system. Two Latin names = scientific name ex: cat nip = Nepeta catariaSlide16

Saintpaulia

Ionantha

‘Elisabeth’Slide17

What is the history of taxonomic classification?

Binomial Name (Scientific Name)

The

first name (the

genus) is

always

capitalized, while the second name (the

species) is never capitalized. Both names should be italicized In

1969, scientist Robert Whittaker proposed five kingdoms into which all living organisms could be classified. Still in use today.Slide18

Taxonomic classification is considered hierarchical. Works from the top down or from the bottom up.

Kingdom

Division (phylum)

Class

Order

Family

Genus

Species Taxonomic ClassificationSlide19

Activity

With a partner develop a acronym or saying to help you remember the taxonomical classification levels.

Write your final version in your note and on the colored piece of paper.

We will share with the class. Slide20

Taxonomic classification is considered hierarchical. Works from the top down or from the bottom up.

Kingdom

Division (phylum)

Class

Order

Family

Genus

Species Taxonomic ClassificationSlide21

Classification is based largely on

morphology

, which is the study of the internal and external appearance of an organism.

In the case of plants, the structure of flowers and fruit (and to some extent leaves, buds, roots, and stems) is considered.

MorphologySlide22
Slide23

Taxonomic keys are useful in separating dissimilar organisms for the purpose of identification. They are based on plant structures.

One such key, a

dichotomous

key

, is a written set of choices that leads to the name of a plant.

Dichotomous

KeySlide24
Slide25
Slide26
Slide27

Activity

With a partner create a Dichotomous

Key for any set of unknown items.

Remember to start with most obvious choices and work down to more specific

Only TWO options per “line”

Can be any item (classmates, locker items, dairy cattle breeds,

northwoods baseball teams, etc.)We peer check the keys for accuracy.
