2. Which of the two (pistil or stamen) is the female part of the flower?
Plant reproduction
Sexual Reproduction in Plants
Requires that
Flowers form (complete flowers)
Pollination and Fertilization occurs
Seeds develop
Seeds grow into new plants
Flower Induction
Flower functions to attract pollinators
Produces gametes (sex cells)
Sepals and petals appear large and colorful
Which of the two (pistil or stamen) is the female part of the flower?

3. Pollination & Fertilization
Transfer of pollen from anther to stigma
Many agents for transporting pollen
Wind
Insects
Birds
Bats
Self Pollination- when the pollen is transferred to the stigma of the same flower
Can be natural or accompanied by humans
After pollination a cell from the pollen grain travels through the style to the ovary
Fertilization- the union of the gametes from the pollen and the ovary of the plant
After fertilization, the fruit and seeds are created and begin developing

5. Asexual Reproduction
Ensures that the new plants will be identical to their parents
Also used to dwarf plant or to maintain desirable traits
8 Common types of asexual reproduction
Cuttings
Grafting
Budding
Layering
Separating

6. Cutting Most common method of asexual reproduction
Portion of a plant is removed and made to form roots
Stem Cuttings
Tip Cuttings
Medial Cuttings
Single or Double Eye
Heel Cutting
Leaf Cutting
Root Cutting

7. Grafting Join plant parts so they will grow as one plant
Four conditions must be met for successful grafting
Scion and rootstock must be compatible
Each must be at the proper physiological stage
Cambial layers of the scion and stock must meet
Graft union must be kept moist until the wound has healed.

8. Budding
Union of bud and a small piece of bark from the scion with a rootstock
Faster, forms a stinger union than grafting
Kinds of budding
Patch budding
Chip budding
T-Budding

9. Layering
Stems attached to their parent plant form roots where they touch the soil
This rooted stem becomes a new plant
Method has high success rate
Prevents water stress and carbohydrate shortage
Types of Layering
Tip layering
Simple Layering
Compound Layering
Mound Layering
Air Layering

10. Separating and Division
Separation
Division
Propagation form when plants that produce bulbs
Bulbs
New bulbs form beside the originally planted bulb
Separate bulb clumps every 3-5 years
Generally pulled apart and replanted immediately
Dig after leaves have withered
Plants with more than one rooted crown can be divided and planted separately
Potatoes are propagated by division
