What makes stem growth possible?
meristems

19. Reading Road Map
Label the leaves on your flower picture.

20. Reading Road Map What are the two functions of leaves? Photosynthesis
transpiration/gas exchange
What do guard cells do for the stomata?
Open or close the stomata

22. Review What are the main parts of a plant?
Roots, Stem, Leaves, Flower or Cone
If a plant doesn’t produce a flower, what does it produce?
Cone
What is the meristem and where is it located?
The tissue that produces new cells
In the roots

23. Review What do the stomata and guard cells do? Where are they located?
Stomata – open and close for gas exchange and prevent water loss
Guard cells – allow the stomata to open and close
They are located underneath a leaf
What is the fruit of a plant?
The mature ovary
What do seeds and the cuticle have in common?
Seeds and cuticles both provide protections
What is transpiration?
The movement of water from the leaf to the atmosphere

24. Plant Classification Nonvascular Plants No xylem or phloem
Examples: liverworts, hornworts, moss

25. Plant Classification Seeded plants Examples: club mosses and ferns
Vascular Plants
Have a xylem and phloem
Seedless plants
Examples: club mosses and ferns
Seeded plants
Examples:
Nonflowering: gymnosperms cones
Flowering: angiosperms  flowers

26. Classification of flowering plants
Monocot
Dicot

27. Plant Tissues
Stem

28. Plant Tissues
Leaf

29. Plant Tissues
root

30. Functions of the plant organs
Flowers
Protect the reproductive structures (gametes)
Leaves
Photosynthesis and transpiration
Stems:
Structure for flower and leaves
Transport material
Store food and water
Roots
Anchor plant/structure
Absorb water and nutrients

31. Movement of Fluids Transpiration Cohesion and Adhesion Absorption
Evaporation of water through the stomata
Cohesion and Adhesion
Moves water up the plant by creating tension
Absorption
Water and minerals are pulled into the roots from the soil

32. Roots Purpose of root hairs?
Add to the surface area of a plant to absorb more water and nutrients
Purpose of meristem?
Create new cells through mitosis

33. Stems
Cambium
Plant tissue that can either become the xylem or the phloem
Xylem
Moves water up the plant
Phloem
Moves food from photosynthesis down the plant

34. Leaves
Stomata

35. Stomata
Opens and closes to exchange gas, and allow water to leave
Guard Cells
Controls whether or not the stomata is open or closed

36. Flower Structure
Female Part
Male Part

37. Flower Structure What is the seed? The protective coat of the embryo
What is a fruit?
The ovary of a plant

40. Flower Parts:
Preparing for
Dissection!

41. You are going to get to dissect your own flowers! Yay!
Why do we dissect flowers?
It helps us understand how pollination works!
By identifying each part of the flower and how they relate to pollination, we can connect those relationships in nature that keep the world going round!
We will get a better understanding as to why pollinators are so attracted to flowers!

43. Petals are colorful & sweet smelling to attract pollinators.
Stalk/Stem
It holds up the flower giving support to the flower. Also provides a highway for water & food to supply the plant with it’s needs.
Nectary filled with nectar
Nectary
This is where a rich, sugary liquid called nectar is produced by plants to attract pollinating animals.

44. Ovary
This protects the ovules (potential seeds). Once they are fertilized they will become a seed. The ovary will become the fruit that protects the seeds.
Ovules/Egg Cells
The Ovules (a potential seed) are like the egg in animals and once fertilization has taken place will become the seed.

45. Sepals protect the petals when the flowers are still a bud.
Receptacle
This is the thickened part of a stem from which the flower grows. This is also where the flower attaches to the stalk/stem and in some cases becomes part of the fruit after fertilization e.g. strawberry.
Sepal-
Sepals protect the petals when the flowers are still a bud.

46. The stalk of the pistil that rises up from the ovary.
The female parts of a flower. It contains the ovary, the style, and the stigma.
Style
The stalk of the pistil that rises up from the ovary.
Stigma
The part of the pistil that catches the pollen. There is a sticky substance on the tip to catch the pollen. Shaped different according to the type of flower.

47. The stalk that holds up the anther.
Stamen
The male parts of the flower, made up of filaments and anthers. Responsible for producing pollen.
Filament
The stalk that holds up the anther.
Anther
Located on the top of the filament and holds the pollen until anthers mature. Once the anthers mature, they burst open releasing the pollen.
Pollen
The fertilizing element of flowering plants, made of fine, powdery, grains or spores.
Bee covered in Pollen.
