Plant kingdom diversity

• The plant kingdom includes over 350,000 species with diverse forms.
• These range from single-celled organisms to giant trees.
• Plants are characterized by photosynthesis and a rigid cell wall.
• Historical development led to the changes and extinction of some plant species.

What will be taugh

• About basic systematic groups of organisms
• Diversity among various divisions of the plant kingdom
• Their structural features
• Key stages in the evolution of plant life
• Plant adaptations to diverse environments
• The impact of human activities on species and their environment

You will need to learn to

• Determine a plant's systematic position.
• Identify and compare plants from different divisions.
• Connect plant structural features with their environment.
• Apply biological knowledge to understand evolution and biodiversity.

Variety of organisms and their classification

• Systematics is the study of organism diversity and classification.
• It groups organisms by relatedness and determines a species' place in the organic system.
• Carl Linnaeus (1707-1778) developed a successful system of the organic world.
• Linnaeus emphasized the importance of systematics for studying it.
• He created a binomial nomenclature system using Latin.
• For example, Trifolium medium is клевер средний (medium clover) and Trifolium repens is клевер ползучий (creeping clover).

Modern classifications of the organic world

• It consideres the relationships between organisms.
• Organisms are grouped into increasingly broad categories.
• Species are grouped into genera, genera into families, families into orders, and so on.
• These are called systematic groups or categories.
• The organic world was once divided into two kingdoms: plants and animals.
• Current systems classify cellular organisms into two groups: Доядерные (Prokaryotes) and Ядерные (Eukaryotes) in надцарства or superkingdoms.
• Доядерные includes Бактерии and Архебактерии (Archaea).
• Ядерные includes diverse organisms with unicellular to colonial forms.

About Classifications

• A universally accepted classification is lacking, which is why schools use a traditional classification.
• This groups Ядерные into Грибы, Растения, and Животные kingdoms.
• Viruses, non-cellular life forms, are excluded from this classification.
• Important terms: Systematics, Species, Systematic categories, and Classification

The Species Concept

• A species includes similar organisms interbreeding and inhabiting a specific area.
• A plant's range may be large or small, continuous or fragmented.
• Taraxacum is widespread.
• Pinus pityusa is limited to the Black Sea coast of the Caucasus.
• Some species are rare, requiring protection in the Красная книга or Red Book.

Species criteria

• They are based on a combination of features such as morphology.
• They encompasses external and internal structure.
• Life activities
• The entirety of their lifecycles.

Species and related categories

• Similar related species are united into genera.
• Genera are grouped into families, families into orders, orders into classes, and classes into divisions.
• Отдел is the largest systematic unit in the plant kingdom.
• Plants in divisions share the same structural plan and importaint featuress.
• Покрытосеменные plants have flowers, do undergo double fertilization.
• Modern systematics use categories like the Эукариоты (Eucaryota) and Прокариоты (Procariota) superkingdoms.
• These belong to the empire of cellular organisms or empire.
• A second empire includes non-cellular life forms or вирусы(viruses).

Dandelion classification

• Dandelions are a familiar weed-like plant within plant classification:
• Imperio: Celled Form organismo
• Narada: Eukaryotic (Kernal)
• Kingdom: Plants
• Divisition: Flowering (Angiosperms, Seed encased)
• Class: Dicot
• Order: Aster
• Family: Asteraceae (Aster family)
• Genus: Dandelion
• Species: Dandelion Officinalis

Plant adaptation to environment

• Every species is adapted to its living conditions and geographical area.
• Area of geographic distribution of the species is name for this: Areals
• The number and range of many species are impacted by human activities
• Increase on the number of species of weeds

Remembering Plant species

• Systematics of the plant
• Systematic Units: View, Genus, family, order and class
• Narada
• Prokaryotes and Eukaryotes
• The plants has been put in comparison to its environment
• The textbook provides a plan for studying plant structure, and offers a practical task for learning about the features of green algae.

The kingdom of seaweed plants

• Water plants
• Have a tallus

Exploring Algae

• Specialists haven't agreed on a single definition of algae.
• They vary so widely in structure and life activity.
• They do not all agree on any similarity.

The position of seaweed in the organic systems

• Some tradition see green weed as some of the lowest plants
• Some see see weed as a special kind of Protista

Domestic and scientific Literature

• See weed are either classified into
• Bugyanki
• Real seaweed

Oddities in classifications

• Some variety that belongs to different divisions that
• Lost their photosynthesis abilities and completely moved to other form of alimentation
• Also some kind does asexual reproduction with the help of special forms

Success from plant life

• By means of zhe eyes: you get a better idea of the new info
• It is important to properly see
• At work with a picture of an illustration, comply with these steps: look and examine the picture.
• Describe the illustrated as best possible
• Make Questions

Seaweed

• It is very unique
• They make unique forms for many life processes

Study of seaweed

• It will be shown for the next lesson: Food
• The cleaning of Water and Oxygen
• Kalimy Soli Leharstva

Algae

• People have cultivated alga since the 17th century.
• They are know and more ancient than we thing
• Many seaweed and plants are used as food for some

Different characteristics

• A large portion are different
• It can grow out 45cm in 24 hrs
• 99339 percent light
• Some is found where very cold

Algys are amazing

• Diatomowe the most numerous of different cells
• 3300 different kids

Plant life to human

• All are interconnected and help to eat
• Make medical products as needed through our life

Weed information

• May help human more than harm
• One plant are used for this
• Some of them

Studing weed

• Take notes and read for this
• Will show a large amount that are need to know

Higher spore plants

• Fossils show different data about there life
• How do higher plants differ
• Plant life is very different than in life

All these spores did what at end

• Evolved form
• Did take care of most life style
• Most like to live to create a family

Types of plant with them

• Pohavidnie is most known for this
• Different other do live in cold
• Must have water to have family

How the plant life live

• Plant cycle
• Cycle that has high need to live from the ground
• New seed = all with time

To have a plant in life needed

• Water
• Spors

Type of plant to have them

• High spors
• Can do many thing about that and more

After the spoures are gone a few think

• Give a new name
• To see where the life will be
• Know how it all starts

List of plant

• Moss
• Spores
• The area around

A part on each

• Moss plant life are good to come
• And good to look for thing about it

A few know forms

• Lives will
• Like to see with
• Are good to be around

Spoorous plant all have

• Are hard for time and more
• So for plant are new form

Other Plant

• Must have leaf on life
• Will do a few thing
• Can not get any

The nature of them all

1- A thing need what are high to do on the world 2- The nature life has all 3-The nature life take a large part on life and world
