4. Plant Body
Shoot system = leaves + stem
Root system

5. Stoma = opening in the leaf for gas exchange, water evaporation
Plant Body
Leaf = blade + petiole
Functions
Exposes surface to sunlight Major site of photosynthesis Conserves water Provides for gas exchange
Blade
Petiole
Stoma = opening in the leaf for gas exchange, water evaporation

6. Transports water and sugar to stem and roots
Conserves water
Photosynthesis
Transports water and sugar to stem and roots
Structures of the Leaf

7. Phloem transports sugar
Plant Body
Stem:
Functions
Holds leaves up to light
Transports substances through vascular tissue
Phloem transports sugar
Xylem conducts water
and minerals

8. Plant Body
Root Functions Anchors plant in soil Takes up water and minerals from soil

9. Flowering Plant Reproduction
Pollen grains
Ovule
Flower
Meiosis
Mitosis
Flowers are modified leaves, specialized for reproduction.
A complete flower has both male and female parts

10. Angiosperms are seed bearing & fruit producing or flowering plants.

11. Flowers
Come in many different shapes, sizes and colors, but they all have the same functions:
help plants reproduce.
where seeds are made.

12. Flowers are the sexual reproductive organs of plants.
All flowers, regardless of variety, have the function of seed formation and the production of more plants.
Flowers contain both non-reproductive and reproductive structures.

13. The parts of a flower Sepals protect the bud until it opens.
Petals attract insects.
Stamens make pollen.
Carpels grow into fruits which contain the seeds.

14. Male Parts

15. Anther This is the part of the stamen that produces and contains pollen.

16. Filament This is the fine hair-like stalk
that the anther sits on top of.

17. Stamen This is the male part of the flower
Stamen This is the male part of the flower. It is made up of the filament and anther, it is the pollen producing part of the plant. The number of stamen are usually the same as the number of petals

18. Female Parts

19. Stigma It is the sticky surface at the top of the pistil
Stigma It is the sticky surface at the top of the pistil . It traps and holds pollen and starts the fertilization

20. Style The tube like structure that hold up the stigma.

21. Ovary The part of the plant, usually at the base of the flower, that has the seeds inside and turns into the fruit that we eat.

22. Ovule The structure of the flower that develops into a seed when fertilized. (eggs)

23. Carpe/Pistil The carpel is the female reproductive organ of a flower
Carpe/Pistil The carpel is the female reproductive organ of a flower. It makes seeds. It is made up of the stigma, style and ovary. There may be more than one carpel in a flower.

24. Pollination
Pollen is the powdery grains that contain male reproductive cells of most plants produced by anther.
Flowering plants use the wind , insects bats, birds and mammals to transfer pollen.

25. When pollination occurs, pollen moves from the male parts to the female parts.
Pollen grains land on the stigma and a tiny tube grows from it and down the style into the ovary.

26. The fertilized ovule becomes the seed and the ovary become the fruit
