1. Kingdom Plantae

2. Kingdom Plantae Complex multicellular eukaryotes
Cell walls made of cellulose
Undergo photosynthesis

3. Kingdom Plantae (con’t)
Exhibit alternation of generations
Sporophyte (diploid)
gametophyte (haploid)
Life Spans: annual, biennial, perennial

4. Plant Tissues Dermal tissue Vascular tissue Ground tissue
Xylem
Phloem
Ground tissue
Meristematic tissue
Plant Tissues
Carries water upward from roots to every part of the plant
Transports nutrients and
carbohydrates produced by photosynthesis

5. Plants Four basic Needs
Sunlight
Water and Minerals
Gas exchange
Transport of nutrients throughout the plant body

6. Four types of flowering Plants Cladogram
Cone-bearing
Ferns
Mosses
3 Ways that Botanist separate groups of plants
Plants evolved from

7. Diversity of Plants Cone-bearing plants 760 species
Ferns and their relatives 11,000 species
Mosses and their relatives 15,600 species
Flowering plants 235,000 species

8. Mosses & Their Relatives
Bryophytes
Mosses & Their Relatives

9. Bryophytes
Also known as mosses

10. Bryophytes (Mosses & Relatives)
Lack vascular tissue (tissue specialized to conduct water and nutrients)
so they are low-growing plants found in moist, shaded areas
Depend on water for reproduction

11. Bryophytes (Mosses & Relatives)
Recognizable gametophytes
Archegonium – female
Antheridium – male
Produce diploid spores

12. Three Groups of Bryophytes
Mosses
Liverworts
Hornwort

13. Common Moss Structures:

14. Bryophyte Lifecycle
Gametophyte carries out photosynthesis because green

15. Seedless Vascular Plants
Ferns & their Relatives

16. Ferns & Relatives
Bryophytes

17. Seedless Vascular Plants
Ferns – most common
True roots/stems/leaves (vascular tissue)
Rhizomes
Fronds – large leaves
Found in wet habitats

19. Seedless Vascular Plants
Club Mosses
Horsetails
Spore-Bearing Vascular Plants
Ferns Club Mosses Horsetails

20. Lifecycle Dominate Stage is the sporophyte
Notices the spores are haploid
