Slide 1

Plant Diversity The Evolution and Classification of Plants

Slide 2

Warm-up: Write every Question and Answer for Each. What do I think about plants? Genuine or False All plants perform photosynthesis. Everything plants need water and supplements. All plants recreate utilizing blossoms. All plants recreate utilizing seeds.

Slide 3

Slide # 3 PLANT CHARACTERISTICS Multicellular eukaryotes Photosynthetic autotrophs containing chloroplasts . Non-versatile (altered to one spot) Cell dividers made of cellulose Responds to environment and becomes through the utilization of hormones

Slide 4

Slide # 4 Plants Make The Move to Land The precursors of plants were multicellular green growth . They were totally drenched in water & broke up minerals. To move onto area, plants needed to take care of these issues : How to get synthetic assets (water, minerals, oxygen, and carbon dioxide) isolated into air and soil How to transport assets inside of the plant. The most effective method to keep from drying out How to repeat without water

Slide 5

Slide # 5 Some Adaptations (arrangements) - Have body parts reaching out into both air and soil Develop a vascular framework to transport assets in plant Have a defensive layer – fingernail skin (waxy external layer) to keep from drying out Specialized structures for multiplication including spores & seeds that don\'t dry out

Slide 6

Slide # 6 Plants are ordered in light of regardless of whether they have Vascular System (transport) Seeds Flowers (encased seeds)

Slide 7

Slide # 7 Concept Map: Plants are isolated 1 st by regardless of whether they have a vascular framework. Plants Bryophytes Has NO Vascular Tissue Has Vascular Tissue Tracheophytes

Slide 8

Bryophytes - NONVASCULAR Slide # 8 Most primitive plants Found in sodden, shady regions NO vascular (transport) framework Small size because of no vascular tissue No genuine roots, stems, or leaves Needs water for generation. Repeats utilizing spores , - a water-evidence single cell that can develop into another living being. Most normal illustration: Mosses

Slide 9

Typical Moss Plant (most basic bryophyte) Slide # 9 Spores structure inside the case. Notice the issue of supplement detachment into air and soil is understood with underground or more ground parts. (Albeit NO TRUE roots, stems or leaves are available)

Slide 10

Slide # 10 Tracheophytes - Vascular Plants-Contains two sorts of specific vascular tissues for transport inside of the plant: Xylem - transports H 2 0 up from roots. Phloem - transports nourishment made amid photosynthesis and supplements to where they are required in the plant. Vicinity of a vascular framework permitted plants to wind up tall. Has specific organs: roots, stems, and takes off.

Slide 11

Slide # 11 Tracheophytes are separated into two gatherings by regardless of whether they recreate with seeds . Tracheophytes Seeded Seedless Ferns use spores

Slide 12

Slide # 12 The Fern - a seedless vascular plant There are 11,000 types of greeneries. Contain a vascular framework. They develop in soggy, shady environments. Has underground stems, roots, & huge leaves called fronds . Imitate utilizing spores , Not seeds. Sori

Slide 13

Slide # 13 Seed-Bearing Tracheophytes ADVANTAGE : Developed regenerative procedures that needn\'t bother with water : Seed contains A completely created fetus Food supply for incipient organism A water-verification seed coat to keep from drying out Sperm moved in water-confirmation dust through fertilization by wind or creatures. Created seed-bearing structures: Cones and Flowers

Slide 14

The two Seeded Tracheophyte gatherings are isolated by regardless of whether they have encased seeds - secured inside a natural product or if seeds are presented to the earth. Tracheophytes Seeded Seedless Ferns use spores Gymnosperms Angiosperms “naked” or uncovered seeds Flowers produce natural product w/encased seeds

Slide 15

Slide # 15 Gymnosperms-“naked seed ” Cycad (Sago palm), Ginkgo , Conifer (pine, spruce, firs, cedars, sequoias, redwoods, junipers, yews, & cypress trees) Sago Palm Ginkgo

Slide 16

Sequoia Slide # 16 Gymnosperms-Conifers Most regular gymnosperms are Conifers have leaves called needles or scales have a diminished surface region and thick waxy coat on the needle to decrease water misfortune and averts solidifying. Juniper Pine

Slide 17

Slide # 17 Conifer Reproduction Pollen Male cones produce dust and the female cone produces eggs and seeds . Dust is wastefully exchanged by the wind. Once develop, the scales on the female cone dry out and open dissipating the seeds by the wind. Seed Cone Pollen Cone

Slide 18

Slide # 18 Angiosperms-“enclosed seeds” These are blooming plants the energize immediate and proficient dust exchange (notice, shading and offering nectar) Pollinators are flying creepy crawlies, winged animals, and bats that exchange dust from blossom to bloom. Blooms contain ovaries, which is the place eggs/seeds are delivered. An organic product is the pollinated ovary containing adult seeds .

Slide 19

Slide # 19 Fruit can help in dispersal of seed to lessen rivalry with guardian plant. Winged natural product – coasts to new area (maple organic product) Floating natural product – can buoy to new areas (coconut) Fleshy organic product - sweet brilliant hued natural product have seeds that survive the digestive arrangement of creatures that eat the organic product (apple) Spiny organic product Velcro like projections append to the hide of creatures (cockleburs) Maple seeds: Winged organic product Burdock: Spiny natural product

Slide 20

Quiz Time What did plants need to overcome to live ashore? What is the most primitive division of plants on the grounds that they have no vascular framework? What is the most widely recognized sample in this division and how would they duplicate? Why are greeneries so little? What is the division of plants that contain a vascular framework? What did a vascular framework accomplish for plants size-wise? How are greeneries and plants diverse? How are greeneries and plants alike?

Slide 21

Quiz Time How are Tracheophytes not quite the same as bryophytes? How are tracheophytes partitioned? What are the benefits of seeds over spores? What different favorable circumstances did seed-bearing plants have over spore-bearing plants? What are the two divisions of the seed-bearing tracheophytes?

Slide 22

Quiz Time What does the term Gymnosperm mean? What are the most well-known of the Gymnosperms? What is the developmental significance of needles? What structures do conifers utilization to duplicate? Were are seeds situated in the cone? Despite the fact that twist dispersal of dust is wasteful, what did it permit plants to succeed?
