1
The odd ones out
2
PlantaeAnimalia Cell Walls (cellulose) Cuticles Photosynthesis Reproduction (2 life stages) No Cell Wall! Consumers Movement Specialized Parts Sexual Reproduction (mostly)
3
Cell Walls Heterotrophs Secret Lives Spores
4
Cell Walls Made of Chitin Same substance that arthropods use for their exoskeletons
5
Heterotrophs No Chloroplast so they have to consume others They either live next to, on or in their food They are either decomposers, parasites or live in mutualism with another organism When a fungus lives in the roots of plants helping the plant to get nutrients and getting food back it is called a mycorrhiza
6
Secret Lives Majority of a fungus lives below the surface either the dirt or the organism it is on Their cells are grouped in chains called Hyphae Hyphae usually grow close to each other in a tangle called mycelium
7
Spores Fungi can reproduce asexually and sexually Asexual Reproduction in Fungi Broken pieces can grow into new fungi Can send out spores that wait until right conditions to grow Sexual Reproduction in Fungi Grow structures that send out Sexual spores, they fertilize and then grow when the conditions are right
8
Fungi are classified based Shape How they reproduce
9
Threadlike Fungi Shape Parts of the hyphae grow out of the ground How they reproduce Asexually: form sporangia that releases spores Sexually: two hyphae meet form different sporangia
10
Sac Fungi Shape No signature shape How they reproduce Asexually: Most of the time, Yeast do budding leaving scars Sexually: Form sacs called ascus
11
Club Fungi Shape Grows club shaped basidia How they reproduce Asexually: N/A Sexually: Basidia
12
Imperfect Fungi Shape No pattern How they reproduce Asexually: No pattern Sexually: N/A
13
PlantaeAnimalia Cell Walls (cellulose) Cuticles Photosyn- thesis Reproduc- tion (2 life stages) No Cell Wall! Consumer Movement Specializ- ed Parts Sexual Reproduc- tion (mostly) Cell Walls (Chitin) Heterotro- phs Secret Lives Spores Fungi
14
Defined more by what they are not, than what they are. Protista have only two traits that they all share; Eukaryotic, and no specialized tissue
15
ProducerConsumer Have Chloroplasts Undergo Photosynthesis Autotroph (self-feed) Some are consumers like animals Decomposers Parasites feeding on a Host Heterotroph(different feed)
16
Asexual Reproduction Divide the parent cell to make identical offspring Called “fission” Binary fission makes two copies Multiple fission more than two copies
17
Sexual Reproduction No set pattern
18
Reproductive Cycles Protist reproduces after significant events Lots of variety Example: Protist lives in one form in mosquito is transferred to a host where it reproduces into another form, then transferred back to a mosquito
19
Broken down into three groups Protist Producers Heterotrophs that can move Heterotrophs that can’t move
20
Red Algae Producer Chlorophyll with red pigment Most common seaweed – grows in the Tropics at deep depths
21
Green Algae Producer Chlorophyll Most Diverse group of Protist Producers
22
Brown Algae Producer Chlorophyll with yellow brown pigment Seaweed in cooler climates Can grow up to 60 m in one growing season
23
Diatoms Producer Chlorophyll Large portion of Phytoplankton Have 2-part glass like shell made of Silica Come in various shapes
24
Dinoflagellates Producer - Sometimes Chlorophyll – Sometimes Some live in fresh water, some Salt water, some in SNOW! Have two flagella
25
Euglenoids Producer - sometimes Chlorophyll – sometimes When food is scarce all of them become heterotrophs Live in freshwater and move with a flagella
26
Amoebas Consumer or Parasites Fresh and salt water Move using pseudopodia (false feet)
27
Shelled Amoeba- Like Consumer Fresh and salt water Have an outer shell Poke psuedopod out of pores in the shell
28
Zooflagellates Consumer or Parasites Move by waving flagella back and forth
29
Cilliates Consumer Thousands of Cilia(hair-like structures) Cilia push food toward the mouth and make it swim
30
Spore-Forming Protist Consumer Many parasites No Cilia/Flagella Have complicated life-cycles (2 hosts usually)
31
Water Molds Consumer some decomposers most parasites
32
Slime Molds Consumer Can move in some life stages Grow as long as food and water is available Some become large cells with many nuclei up to 1 m across Reproduce by growing stalks that release spores
33
Is a combination of fungus and algae Alga lives inside the fungus Such a close and dependant life cycle that they are considered one organism Producers Fungi cell walls protect alga and keep in water Very sensitive to air pollution
