Fungi are…organisms that consume food –
mainly breaking down dead and decaying matter
organisms that have a nucleusorganisms that have a cell wall

Think-Pair-ShareWith your partner, list the 5 ways
that fungus might be classified. (Reflect back on your notes on classification). After discussion, place a star next to those used to classify fungus.

Major Structures
![Page 6: Kingdoms Fungi and Plantae](https://reader035.fdocuments.net/reader035/viewer/2022062218/56816586550346895dd838b8/html5/thumbnails/6.jpg)
Major Structures1. Hyphae – tiny filaments that
make up the fungus2. Mycelium – many hyphae tangled
together3. Fruiting Body – Reproductive
structure that develops from a mycelium and grows below ground

Check for Understanding With your partner, label the following
diagram with the major structures of a fungus
![Page 8: Kingdoms Fungi and Plantae](https://reader035.fdocuments.net/reader035/viewer/2022062218/56816586550346895dd838b8/html5/thumbnails/8.jpg)
Common MoldsSexually reproducing fungiHyphae generally lack cell
wallsExamples: black bread mold
![Page 9: Kingdoms Fungi and Plantae](https://reader035.fdocuments.net/reader035/viewer/2022062218/56816586550346895dd838b8/html5/thumbnails/9.jpg)
Sac FungiReproduce both sexually and
asexuallyCan be unicellular and
multicellularExamples: Cup Fungus, Yeasts

Club FungiThese fungi can be edibleThis is an extremely diverse category
of fungus Examples: Orange Jelly, Shelf Fungus,
Mushrooms

Imperfect FungiAll fungi that are not placed into
other groups (phyla) are placed here
NEVER been shown to have a sexual life cycle
Example: Penicillium
![Page 12: Kingdoms Fungi and Plantae](https://reader035.fdocuments.net/reader035/viewer/2022062218/56816586550346895dd838b8/html5/thumbnails/12.jpg)
Interactions with the Environment
Decomposers – break down dead matter into the nutrients that make it up
Nutrient recyclers Positive relationship with treesCause famine, and disease in
plants, animals, and humans

Most plants…Autotrophs – make their own
foodHave a NUCLEUS!MulticellularHave a cell wall
![Page 15: Kingdoms Fungi and Plantae](https://reader035.fdocuments.net/reader035/viewer/2022062218/56816586550346895dd838b8/html5/thumbnails/15.jpg)
Plants make a move from water to land!Evolved from organisms like green
algae Evolution required adaptations
Waxy Cuticle – protects from water loss
Vascular tissue – helps move water and nutrients through the plant
Seeds/Flowers – allows for sexual reproduction
![Page 16: Kingdoms Fungi and Plantae](https://reader035.fdocuments.net/reader035/viewer/2022062218/56816586550346895dd838b8/html5/thumbnails/16.jpg)
Non-Vascular PlantsLack specialized tissue to help
move food and waterVery shortExamples: mosses, liverworts,
hornworts
![Page 17: Kingdoms Fungi and Plantae](https://reader035.fdocuments.net/reader035/viewer/2022062218/56816586550346895dd838b8/html5/thumbnails/17.jpg)
Vascular Plants Xylem and Phloem move water and food All have true roots, leaves, and stems Some are seedless:
Some have seeds: angiosperms, gymnosperms Seeds allow the plant to reproduce without water
![Page 18: Kingdoms Fungi and Plantae](https://reader035.fdocuments.net/reader035/viewer/2022062218/56816586550346895dd838b8/html5/thumbnails/18.jpg)
Check for Understanding With your partner, hypothesize why it
was important for vascular tissue to develop in land-dwelling plants.
There is not ONE correct answer! Enabled plants to grow taller, allowed plants to get nutrients more easily, allowed plants to grow deeper roots to access water because it can move throughout the plant, provided plants with more structure and support

Gymnosperms
Known as flowering plants, any plant that bears seeds within a layer of tissue that protects the seeds
Examples: apple tree, rose Two types: monocots, dicots
Angiosperms
Any plants that bear their seeds directly on the surface of cones
Examples: ginkgoes, cycads
![Page 20: Kingdoms Fungi and Plantae](https://reader035.fdocuments.net/reader035/viewer/2022062218/56816586550346895dd838b8/html5/thumbnails/20.jpg)
MonocotsSingle cotyledon (seed leaves)The veins of the leaves run parallelFloral parts (petals) occur mostly in
multiples of 3Vascular bundles are scattered
throughout the stemFibrous roots
![Page 21: Kingdoms Fungi and Plantae](https://reader035.fdocuments.net/reader035/viewer/2022062218/56816586550346895dd838b8/html5/thumbnails/21.jpg)
DicotsTwo cotyledons (seed leaves)Leaves have branched veinsFlower parts (petals) occur often in
multiples of 4 or 5Vascular bundles arranged in a ringRoots function like a taproot
![Page 22: Kingdoms Fungi and Plantae](https://reader035.fdocuments.net/reader035/viewer/2022062218/56816586550346895dd838b8/html5/thumbnails/22.jpg)
Key Plant Parts Anther – oval sac where pollen is found Filament – long, thin stalk that supports anther Stigma – sticky portion at top of style Petal – attract insects and pollinators to flower Sepal – protect the flower while it develops Ovary – surrounds the ovule (female reproductive
portion of the plant)
![Page 23: Kingdoms Fungi and Plantae](https://reader035.fdocuments.net/reader035/viewer/2022062218/56816586550346895dd838b8/html5/thumbnails/23.jpg)
Check for Understanding With your partner, label the following
picture below with the following terms anther, filament, stigma, style, petal, sepal, ovary, ovule. (You are hypothesizing the location based on the functions we discussed.)
