8. Fruit of a Peanut Plant Forms in the ground
Fertilization of an egg & pollen makes a seed
Fruit is the ovary around the seed

9. Pineapple Fruit

12. Fruit & Seed Dispersal

13. Pollination versus Fertilization
Pollination: Mechanical
Transfer of pollen:
Fertilization: Joining
Of pollen(sperm) with
The egg in ovary

14. Cone Bearing Plants
Gymnosperms
Cones
“naked” seeds
No ovaries
Pollen

15. Ovaries surround the seeds
Seed = Fertilized egg
Ovary becomes the fruit

16. Roots

17. Stems

18. The stem of a plant provides pathways for the distribution of water and nutrients between the roots, leaves, and other parts of the plant. The herbaceous stem of the dandelion (top, center) lacks lignin, the stiffening material in rigid, supportive woody stems. For this reason, herbaceous plants are generally limited in their physical size. Spurges and cacti (bottom, left), their leaves reduced to needles to prevent evaporation in a dry climate, consist entirely of stem material. Tubers, such as potatoes (top, right), are swollen, food-storing, underground stems that nourish growing buds. The stems of some plants are adapted for protection, as in the hawthorn (bottom, right). Others actively compete for sunlight, using touch-sensitive, curling tendrils (top, left) or other structures to climb upwards.
