THE FIVE KINGDOMS

THE FIVE KINGDOMS??

ACTIVITES

harmful functionsbacteria can cause diseases (pathogens)

BENEFICIAL FUNCTIONS Released large amounts og oxigen into the atmosphere break down dead plant and animals and transform it into simpler substances help to digest food productions of food

PROTOZOA

MAIN CHARACTERISTICSEukaryoticsUnicellular Nutrition: heterotrophs(most are hunters and a few are parasites) Habitat: free- living and parasites Reproduction : Asexually and sexually Movement: flagella, cilia or pseudopds, some are sessile

ALGAE

• Cellular organitation: eukaryotic cells. (unicellular or multicellular)
• Nutrition: autotrophic (chlorofyll)
• Habitat and life style (water)
• Reproduction: Asexual and sexual.
• Movement (float, freely by flagela or sessile)

CLASSIFICATION

Fungi Kingdom

• Eukariotic : unicellular or multicellular. They not have true tissues
• Heterotrophs : saprotrophs, parasites, symbionts
• Reproduction : Asexual or sexual.
• Some multicellular fungi are made up of fine threads called hyphae(moulds)
• When the hyphae are packed together , they form mycelium (mushrooms)
• Ecological and economical importance
• Deseases

YEASTS

• Unicellular
• Small and round
• Asexually
• Free- living or parasites
• Uses: fermentation processes (bread, beer...)

MOULDS

• Multicellular
• Many are microscopic
• Structure: Hyphae and micellium
• Reproduction by spores
• Pasasites and saprophytes
• Uses: making cheese, fertilizing gardens and decaying rubbish

MUSHROOMS

• Multicellular
• Free -living and parasites
• Reproduction by spores
• Uses: food

FERNS

• Vascular, conducting tissues are pressent
• Larger and complex than mosses
• True roots, stems and leaves
• The stem (rhizome )grows underground
• The leaves are called fronds
• They reproduce by spores (sorus)

GYMNOSPERMS

• They have flowers (cones) without calyx or corolla.
• Their flowers are unisexual
• They reproduce by seeds no protected inside a fruit
• They are woody plants (trees and large shrubs)
• Their leaves are green all year around (evergreen)
• Conifers are the most abundant group (pines trees , cypresses, junipers..)

GYMNOSPERM LIFE CYCLE

ANGIOSPERMS

• The most numerous plants and adapted to terrestrrial enviroment
• Decidious trees (they lose their leaves in winter
• Flowering plants with seeds inside a fruit
• Thai flowers have calyx and corolla
• Flowers can be unisexual or hermaphrodites
• Herbs (daisy flower, grass), shrubs and trees (fruit trees)

HERMAPHRODITE FLOWER

ASEXUAL REPRODUCTION

SEXUAL REPRODUCTION IN PLANTS

BRYOPHITES

PTERIDOPHYTES

Which are the main characteristics of animals?

INVERTEBRATES

PORIFERA

CNIDARIANS

WORMS

ANNELIDS

PLATHYHELMINTHES

NEMATODES

INSECTS

ECHINODERMS

PROTOCTIST FUNCTION

• FREE-LIVING PROTOCTIST : ZOOPLANKTON (PROTOZOA + MICROSCOPIC ANIMALS) AND PHYTOPLANKTON (UNICELLULAR ALGAE)

• SYMBIONTS: They live in the digestive system of some animals

• PARASITES
