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
Summarize the basic functions of the structures of a flowering plant for defense, survival, and reproduction.

6. Structures for Defense
Without defenses the plant might die. Examples of natural defenses may be:

7. thorns keep plants from being eaten by animals
fruits and leaves with poisons so are not eaten by animals
Some have ability to close leaves when touched (thigmotropism)
Epiphytic orchid

8. Structures for Survival
Examples of parts of flowering plants that function for survival may be:

9. Leaves are the site of photosynthesis, respiration, and transpiration in plants.

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

11. Roots anchor plant in ground.
Absorb water and nutrients from soil and store extra food.
The more surface area on root that is available, the more water and nutrients it can absorb.
Root hairs help increase this surface area.

12. Types of Roots
Fibrous roots: several main roots branch off to form a mass of roots.
Examples: grass, corn, some trees
Taproots: one large, main root with smaller roots branching off.
Examples: carrots, dandelions, cacti

13. Seeds have structures that allow them to be dispersed/spread by wind, water, or animals.
Seed coat helps protect embryo from injury and from drying out.

14. Structure for Reproduction
Flowers
Stamen
Pistil
Seed

15. 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.

16. Stamen Male part has an anther on a stalk or (filament).
Anther produces pollen that contains sperm cells.

17. Pistil Female part contains
Ovary = contains ovules where egg cells are produced,
Stigma = sticky top where pollen grains land, and
Style = stalk which pollen tube grows after pollination takes place

18. Seed
Ovule contains fertilized egg (embryo) from which new plants are formed.
Fruit that is formed from ovary often protects seeds.
