  1. Plant Kingdom EQ: How do parts of plants function for the survival of the whole organism?

  2. Plants With Seeds • General Information

  3. Plants With Seeds • General Information • Life Span

  4. Plants With Seeds • General Information • Life Span • Annuals- reproduce one year/ die Snapdragons

  5. Plants With Seeds • General Information • Life Span • Annuals- reproduce one year/ die • Biennials- reproduce second year/ die The Sweet William Dwarf.

  6. Plants With Seeds • General Information • Life Span • Annuals- reproduce one year/ die • Biennials- reproduce second year/ die • Perennials – reproduce each year/ live many years The Plantain Lilly.

  7. Plants With Seeds • B.Tropism- a plant growing toward or away from a stimulus.

  8. Plants With Seeds • B. Tropism- a plant growing toward or away from a stimulus. 1. Positive tropism – plant grows toward the stimulus.

  9. Plants With Seeds • B. Tropism- a plant growing toward or away from a stimulus. 1. Positive tropism – plant grows toward the stimulus. 2. Negative tropism – plant grows away from stimulus.

  10. Plants With Seeds • B. Tropism- a plant growing toward or away from a stimulus. 1. Positive tropism – plant grows toward the stimulus. 2. Negative tropism – plant grows away from stimulus. 3. Examples:

  11. 3. Examples: Plants With Seeds

  12. 3. Examples: a. Phototropism = response to light – a positive tropism Plants With Seeds

  13. 3. Examples: a.Phototropism = response to light – a positive tropism b.Gravitropism = response to gravity where roots show a positive tropism and stems show a negative tropism. Plants With Seeds

  14. Positive Tropism Phototropism

  15. Sunflower tropism

  16. Negative tropism • Charles Darwin was one of the first to scientifically document that roots show positive gravitropism and stems show negative gravitropism. That is, roots grow in the direction of gravitational pull (i.e., downward) and stems grow in the opposite direction (i.e., upwards).

  17. Example of Geotropism in the remaints of a cellar of a roman villa in the Archeologic Park in Baia, Italy

  18. Negative tropism • Gravity is used to signal root growth downwards and shoots upwards. (Shoots also use light (phototropism) to direct growth away from gravity.)

  19. II.Plant Parts

  20. II.Plant Parts A.Leaves

  21. II.Plant Parts A.Leaves 1. Photosynthesis

  22. II.Plant Parts A.Leaves 1. Photosynthesis a. Definition: food making process in leaves using light energy captured by chlorophyll in the cholorplasts

  23. II.Plant Parts A.Leaves 1. Photosynthesis a.Definition: food making process in leaves using light energy captured by chlorophyll in the cholorplasts b. 6CO2 + 6H2O C6H12O6 + 6O2

  24. II.Plant Parts A.Leaves 1. Photosynthesis a. Definition: food making process in leaves using light energy captured by chlorophyll in the cholorplasts b. 6CO2 + 6H2O C6H12O6 + 6O2 Carbon Dioxide

  25. II.Plant Parts A.Leaves 1. Photosynthesis a. Definition: food making process in leaves using light energy captured by chlorophyll in the cholorplasts b.6CO2 + 6H2O C6H12O6 + 6O2 Water

  26. II.Plant Parts A.Leaves 1. Photosynthesis a. Definition: food making process in leaves using light energy captured by chlorophyll in the cholorplasts b. 6CO2 + 6H2O C6H12O6 + 6O2 Sugar

  27. II.Plant Parts A.Leaves 1. Photosynthesis a. Definition: food making process in leaves using light energy captured by chlorophyll in the cholorplasts b. 6CO2 + 6H2O C6H12O6 + 6O2 oxygen

  28. II.Plant Parts A.Leaves • Photosynthesis c.Reasons photosynthesis is important to humans.

  29. II.Plant Parts A.Leaves • Photosynthesis c.Reasons photosynthesis is important to humans. (1) Starts the food chain for all life forms.

  30. II.Plant Parts A.Leaves • Photosynthesis c.Reasons photosynthesis is important to humans. (1) Starts the food chain for all life forms. (2) Provides O2 to breathe
