1. Kingdom Plantae

2. Plant Characteristics
AUTOTROPHIC
MULTICELLULAR
EUKARYOTIC
MOST TERRESTRIAL
CELL WALLS OF CELLULOSE
Dominant group on land based on weight
DIVERSE!! Range from 2mm to 100m tall!!

3. Are there exceptions?

4. Diversity?

6. Seedless:
hornworts

7. Nonvascular plants
hornwort

8. Vascular plants
Seedless plants

9. Seed plants
Vascular plants
Gymnosperms
Angiosperms

10. Plant Structure

11. Adaptations
What obstacles did plants have to over come to live on land?
DRYING OUT - CUTICLE & STOMATA
MEANS OF REPRODUCTION
MEANS OF GETTING WATER AND NUTRIENTS

12. DIVISION BRYOPHYTA PRIMITIVE: AMONG THE 1st LAND PLANTS NONVASCULAR
NO TRUE ROOT SYSTEM: HABITAT?
NO VASCULAR TISSUE: SIZE?
SIZE LIMITED BECAUSE SPERM MUST SWIM TO FERTILIZE EGGS

13. Moss Structure Plants are about 3cm tall and 1 cell thick
Clump of moss is a bunch of tiny individual plants
Each plant contains rhizoids for anchoring them in soil.

14. Importance IMPORTANT SOIL BUILDERS PREVENT EROSION
PEAT MOSS (SPHAGNUM) GROWS IN BOGS OR PONDS & USED FOR FUEL, MULCH, ETC.

15. Plant Structure
Chloroplast

16. What role do plants play in the Water cycle?

17. What role do plants play in the Carbon Cycle?

18. Mineral Nutrients Phosphorus Calcium Magnesium Sulfur Nitrogen Carbon
Proteins, N.A., chlorophyll, ATP and growth
Carbon
Growth, photosynthesis
Potassium
Active transport, enzyme activation, osmotic balance and stomata opening
Phosphorus
ATP, ADP, N.A., phospholipids of cell membrane
Magnesium
Part of chlorophyll, needed for photosynthesis and activation of enzymes
Calcium
Cell wall, enzymes, cell membrane activity
Sulfur
Proteins, cellular respiration

19. What role do plants play in the Nitrogen Cycle?

20. Nitrogen Cycle Nitrification Denitrification Ammonification
Bacteria in soil take up ammonia and oxidize it into nitrites and nitrates and plants use it to create amino acids
Denitrification
Process of how nitrogen is returned to the atmosphere when bacteria break down nitrates and release nitrogen gas
Ammonification
Decomposers break down waste organisms and release the N they contain as ammonia

21. Discuss Ways that plants move.
Tropisms
Discuss Ways that plants move.
Phototropism
Plant responses to light
Gravitropism
Plant responses to gravity
Photoperiodism
the physiological reaction of organisms to the length of day or night
Thigmotropism
Plant responses to touch

22. Tropisms

23. MALE & FEMALE ON SEPARATE PLANTS
MALE REPRODUCTIVE ORGAN= ANTHERIDIUM
PRODUCES SPERM
FEMALE REPRODUCTIVE ORGAN = ARCHEGONIA
PRODUCES EGG

24. ALTERNATION OF GENERATIONS

27. Photosynthesis
