KINGDOMS NOT Magical NOR Royal!
2
EVOLUTION KINGDOM Fungi Animal KINGDOM Plant KINGDOM KINGDOM Protista
Bacteria KINGDOM
3
Bacteria! Prokaryotes Single-Cells! The GOOD SIDE: MOST are BENEFICIAL
to us and the environment Single-Cells! The BAD SIDE: A FEW can make us sick PRIMATIVE!
4
JUST SAY NO TO ANTI-BACTERIAL
Washing with regular soap is GOOD! JUST SAY NO TO ANTI-BACTERIAL for daily use!!
5
Protista! Unicellular How do they reproduce? Sexual, Asexual OR BOTH!
How do they get food? Heterotrophs! OR BOTH! Multicellular: Many cells working together as one Autotrophs! Some are like animals Colonizing: Individuals that congregate Some are like plants How are they organized? General Characteristics:
6
Protista! Dinoflagellate Paramecium Euglena Diatoms Slime mold Amoeba
Sea Kelp AKA brown algae Red Algae Green Algae
7
NOTICE the relationship
Plants share a close common ancestor with GREEN ALGAE! Can we conclude that plants evolved from PROTISTS?
8
Kingdom FUNGI What can you say about the evolution of fungi?
9
Fungi “cells” called HYPHAE Eat dead, organic matter
General Characteristics! ALL ARE DECOMPOSERS!!! Reproduce Sexually: “SPORES” = Babies HOW DO THEY EAT? MANY are edible Step TWO: suck up or absorb the goodness Step ONE: “spit” digestive enzymes OR Absorptive Heterotrophs
10
Phylum ZYGOMYCOTA BREAD MOLDS!
11
Phylum BASIDIOMYCOTA Mushrooms & Toadstools
14
Phylum Ascomycota Yeasts, Molds/Mildews, & Morels!
Carbonation in first “pop” Skin infections! Risen Bread
15
Foods go “bad” when fungus invades
Bread Mold Experiment! Fungus spores are EVERYWHERE! Foods go “bad” when fungus invades Can YOU determine the BEST environment for bread mold to grow??? THINK ABOUT…. Temperature Light Moisture Air exposure
16
Kingdom Plantae What can you say about the evolution of plants?
17
Types of plants FERNS LIVERWORTS FLOWERING CONIFERS MOSSES
18
Plants…In General eukaryotes multicellular Photosynthetic AUTOTROPHS
NEED CO2 SUN! O2 OUT MOST reproduce sexually But many reproduce asexually VASCULAR SYSTEMS! Need NITROGEN! NEED WATER! Alternation of Generations: Sporophyte to Gametophyte
19
ALTERNATION OF GENERATIONS
Plant Life Cycle
21
VASCULAR SYSTEMS!
22
General Anatomy LEAVES: Capture sunlight
Waxy cuticle to prevent water loss More SA = more chance for dry out STOMATA: pores to allow water & oxygen out VASCULAR TISSUE: Water transport (XYLEM) Transport glucose from photosynthesis (PHLOEM) How are WE similar to plants? ROOTS = anchor & absorb water + nutrients
23
Habitat! WET! Phylum Bryophyta WET! WET! Can grow & reproduce
Mosses & liverworts Similar to algae WET! WET! Habitat! Can grow & reproduce ONLY when wet Short
24
Phylum Pteridophyta Ferns & clubmosses COMPLETE vascular system:
roots; stems; leaves CAN survive in areas of changing seasons STILL DEPEND ON WET HABITAT for full life cycle
25
Phylum Spermatophyta Seeds FREED THEM from WET areas Seed plants
ANGIOSPERMS GYMNOSPERMS
26
Modified leaves = NEEDLES
Gymnosperms Cycads, ginkgoes, and conifers Modified leaves = NEEDLES Last years! Some have CONES Live in dry areas Seeds exposed to AIR
27
Angiosperms FOOD SOURCE! Reproduce & grow to maturity quickly
Monocots & Dicots FLOWERS and SEEDS! Flowers, fruits, vegetables, cactus, grasses, leafy trees FOOD SOURCE! Reproduce & grow to maturity quickly Seed modified to have cotyledons which nourish the developing plant HIGHLY DIVERSE! leaf shapes, sizes, flower patterns
29
Animalia
30
Food Webs!
31
World HUNGER!
