1. Functions of Plant Parts:
1st Quarter

2. Objectives:
Identify major internal structures, external structures, methods of locomotion, methods of reproduction and stages of development of plants:

3. Plants
The plant kingdom is divided into both nonvascular and vascular plants.

4. Vascular
Plants that have specialized tissues that move materials through & provide support to the plant.

5. They obtain water and nutrients directly from their surroundings.
Non-vascular
They obtain water and nutrients directly from their surroundings.

6. Roots:
-Absorbs water & nutrients to the stem that are taken up through the root hairs
-Anchors the plant
-Stores food

7. Leaf »carries out transpiration (where water evaporates from leaves)
» where photosynthesis takes place
»carries out transpiration (where water evaporates from leaves)

8. Transpiration is the process by which plants release water vapor into the air through stomata. If too much water is lost, a plant wilts.

9. Stomata
are tiny holes in a leaf which allow water to evaporate

11. Stem
Transport nutrients from the roots to the leaves in the vessels of the XYLEM and PHLOEM.

12. There are two types of vascular tissue in plants:
Xylem--provides support & conducts water & nutrients from the roots.
Phloem conducts food in vascular plants.

13. A closer look

14. seeds not enclosed by a fruit Non-flowering
Gymnosperm
seeds not enclosed by a fruit
Non-flowering

15. a flowering plant having its seeds enclosed
Angiosperm
a flowering plant having its seeds enclosed
in an ovary.

16. The Parts of a Flower

17. Flower
» The reproductive structure of some
seed-bearing plants

18. Sepals
sepal
--protect the flower before it opens.

19. Petals
attract pollinating insects with their bright color & sweet scent.

20. Stamen are the male parts of the flower.
anther
are the male parts of the flower.
The plant makes pollen in the part of the stamen called the anther.
stamen

21. the pollen-bearing part of a stamen.
Anther
the pollen-bearing part of a stamen.

22. Pollen
the fertilizing element of flowering plants, consisting of yellow grains.

23. The stalk that bears the anther in a stamen.
Filament
The stalk that bears the anther in a stamen.

25. the female ovule-bearing part of a flower.
Pistil
the female ovule-bearing part of a flower.

26. Stigma the top of the female part of the flower.
The pollen from another flower collects on the stigma’s sticky surface.

27. Ovary protects the ovules (eggs).
pollen
protects the ovules (eggs).
Pollen travels to the ovules and fertilization takes place.
Now the ovules will develop into seeds.
ovary
ovule

28. Fruit
» is a ripened ovule together with its associated parts, and often protects the seed.

29. A mature fertilized ovule that contains an embryo
Seed
A mature fertilized ovule that contains an embryo

30. to begin to grow or develop.
Germination
to begin to grow or develop.

32. Write the correct words in the boxes: stamens, stigma, petals, ovary, sepals
pollen sticks to this
where the seeds grow
where the pollen is made
these attract
insects
These protect the flower before it opens
