Warm-Up:

1. Warm-Up: In a paragraph, explain why the celery turned blue/red after being placed in colored water.

2. Warm-Up: Using a Venn Diagram, choose two groups of plants to compare and contrast. *Vascular or Nonvascular, *Seed Producing or Spore-Producing, *Flowering or Cone-Bearing, *Monocot or Dicot

3. Warm-Up: • The purpose of poisonous fruits or leaves on a plant is most likely to _____. • help the plant to get moisture • allow the plant to make more food • protect the plant from being eaten • support the stems and branches • The leaves of which plant, pictured to the right, show the best structural adaptations for protecting the plant from predators?

4. Warm-Up: Draw both root illustrations in your ISN. Determine what type of roots are pictured and label each root. Root One Root Two

5. Structures of Flowering Plants 6.2.4 Summarize the basic functions of the structures of a flowering plant for defense, survival, and reproduction.

6. Flowering plants have special structures that functionfor defense, survival, and reproduction.

7. Structures for Defense Plants have structures for defense that protect them from threats and without these defenses the plant might die. Examples of natural defensesmay be:

8. thorns that defend plant from being eaten by animals • fruits and leaves with poisons so that they are not eatenby animals • ability to closeleaves when touched (thigmotropism) Epiphytic orchid

9. Structures for Survival Plants have structures that allow them to survive in their habitats when the conditions are not suitable. Examples of parts of flowering plants that function for survival may be:

10. Leaves function as the site of photosynthesis, respiration, and transpiration in plants.

11. Stems support plant, hold leaves up to light, and function as food storage sites. • Xylem in stems transports water from roots to leaves and other plant parts. • Phloem in stems transport food made in leaves to growing parts of plant.

12. Rootsanchorplant in ground. • Absorbwater and nutrients from soil and store extra food. • The more surface areaon root that is available, the more water and nutrients it can absorb. • Roothairshelp increase this surface area.

13. Twotypes of roots: fibrous roots and taproots. • Fibrous roots: severalmain roots that branch off to form massof roots. • Examples: grass, corn, some trees • Taproots: one large, main root with smaller roots branching off. • Examples: carrots, dandelions, cacti

14. Seeds have special structures that allow them to be dispersed by wind, water, or animals. • Seed coat helps protectembryo from injury and from drying out.

15. Structure for Reproduction Parts of flowering plant that function in reproductioninclude: • Flowers • Stamen • Pistil • Seed

16. Flowers • Flowers produce seeds. • Many flowers contain both male and female parts needed to produce new flowers. • Flower petals are often colorful or have a scent to attract insects and other animals.

17. Stamen • Male part that has an anther on a stalk (filament). • Antherproduces pollenthat contains sperm cells.

18. Pistil • Femalepart contains • Ovary= contains ovuleswhere egg cells are produced, • Stigma= sticky topwhere pollen grains land, and • Style=stalkwhich pollen tube grows after pollination has taken place

19. Seed • Ovule contains fertilized egg (embryo) from which new plants are formed. • Fruitthat is formedfrom ovaryoften protects them.
