1 Kingdom Plantae

2 What’s a plant? Multicellular Eukaryotic Cells walls made of cellulose
Develop from multicellular embryos Carry out photosynthesis using chlorophyll a and b pigments autotrophs

3 Plant Life Cycle Alternations of generations
Plants cycle between the haploid (gametophyte) and diploid (sporophyte)

4 The Plant Kingdom Green algae are thought to have given rise to the
“higher” plants.                                                           They have the same pigments, storage products, and cell-wall type. Also, many of them live in fresh water… The different plants selected for adaptations that allowed them to exploit more of the terrestrial regions…

5 Things plants need to survive
Sunlight Water and minerals Gas exchange (carbon dioxide in, oxygen out) Movement of water and nutrients

6 The Plant Kingdom

7 Non- vascular plants (Bryophytes)

8 Bryophytes Life cycles depend on water for reproduction
All live in moist areas Lack vascular tissue Draw up water by osmosis Live only a few centimeters above ground No seeds produced Ex. Mosses, liverworts, hornworts

9 Bryophytes

10 Seedless vascular plants, seed plants

11 Vascular plants are different b/c
The vascular tissue system is responsible for transport of water, minerals, sugars, and plant hormones. Plants also produce lignin – makes cell walls rigid

12 2 Main Types of Vascular Tissue
Xylem – moves water and minerals from roots all parts Phloem – transports nutrients and carbs made during photosynthesis, also hormones

13 Seedless Vascular Plants
Most basic plant type with vascular tissue True roots, leaves and stems Use spores for reproduction Ex. Ferns, horsetails

14 Ferns and Their Relatives

15 Seed Plants Classified as gymnosperms or angiosperms
Seed formation allows reproduction without water Plants make cones or flowers Sperm is transferred during pollination Male gametophyte – pollen grain Embryo is protected in a seed, seed provides food and keeps embryo from drying out

16 Gymnosperms Cone- bearers
Reproduction takes place in cones produced by a mature sporophyte plant Produce 2 types of cones: pollen (male) and seed (female) Exs gnetophytes, cycads, ginkgoes, and conifers

17 Gymnosperms

18 The Plant Kingdom – Reproduction
Gymnosperms:

19 Angiosperms Flowering plants Flowers
reproductive organs contain ovaries that surround/protect seed After pollination the flower develops into a fruit Grouped as monocots and dicots

20 Dicots and Monocots Named for number of seed leaves (cotyledons) in the plant embryo

21 Monocots vs. Dicots Monocots 1 cotyledon seed
Flower petals in multiples of 3 Parallel veined leaves Vascular bundles distributed through out a stem Fibrous roots Dicots 2 cotyledon seed Flower petals in multiples of 4 or 5 Branch veined leaves Vascular bundles as a ring in stem Taproot
