1. Plants Basics Survival, Reproduction & Defense

2. Essential Standards 6.L.1 Understand the structures, processes and behaviors of plants that enable them to survive and reproduce.

3. Clarifying Objectives 6.L.1.1Summarize the basic structures and functions of flowering plants required for survival, reproduction and defense.

4. Essential Questions How are plants built? (What is it’s structure) How do plants use their parts for DEFENSE? How do plants use their parts for SURVIVAL? How do plants use their parts of REPRODUCTION?

5. Plants Structures Plant STRUCTRUES are how the plants are built Each plant part has a different responsibility to protect, help the plant survive or help it reproduce The basic parts of a plant are – Roots – Stem – Leaves – Flower

7. Structures (Parts of the Plant) for Defense Plants have structures for defense that protect themselves from being eaten or drying out http://www.youtube.com/watch? v=veMvxMGHZzo http://www.youtube.com/watch? v=veMvxMGHZzo These defenses have devolved over time (thousands of years) to help the plant not get eaten – Thorns- Protect plants from being eaten by animals – Poisons- some plants release poison so when animals eat them they die – Thigmotropism- this is when leaves close when they are touched

8. Natural Plant Defense Thigmotropism- When the leaves of a plant close when you touch it http://www.youtube.com/watch?v=hHoxl_6N_x4 http://www.youtube.com/watch?v=hHoxl_6N_x4 Poison- Some plants release poison when the plant is eaten which kills the animals that eat it Thorns- Some plants have prickly thorns so animals can’t eat the plant

10. Structures (Parts of the Plant) for Survival Plants have structures (Parts of the plant) that enable them to survive in their specific habitat or Biome – Leaves – Stems – Roots

11. Structures (Parts of the Plant) for Survival {Leaves} Leaves are where photosynthesis, respiration & transpiration takes place which are necessary to the plants survival PHOTOSYNTHESIS makes FOOD & ENERGY for the plants

12. Structures (Parts of the Plant) for Survival {Stem} Stems of the plant – Hold the plant up – Store some of the extra food & energy made during photosynthesis – Contains the Xylem which transports water to the whole plant – Contains the Phloem which transports food (glucose) to the rest of the plant

13. Structures (Parts of the Plant) for Survival {Roots} Roots are necessary to the plants survival for several reasons – Anchor the plant to the ground – Absorb the groundwater

14. Essential Questions Get with a partner and answer… How do plants use their parts for SURVIVAL?

15. Structures (Parts of the Plant) for Reproduction {Flower} Reproduction to create more plants happens in the flower of the plant The flower contains the male structure & female structure along with the seed

16. Flower (Male) The male part of the flower is called the Stamen The stamen contains two parts called – Filament – Anther The Anther produces the pollen which contains the SPERM

17. Flower (Female) The Female part of the plant is called the Pistil The Pistil is made from 4 parts – Stigma – Style – Ovary – Ovule

18. Essential Questions Get with a partner and answer… How do plants use their parts of REPRODUCTION?

19. Important Points Plants have structures for three reasons ①Provide DEFENSE ②Carry out processes for SURVIVAL ③REPRODUCTION Leaves, Roots, Stem carryout SURVIVAL processes for the plant Flower helps plant REPRODUCE Plant DEFENSE includes – Thorns – Thigmotropism – Poisons
