I love this power point. It really would help me teach my special education students. It would really help me teach them the standards! I would like permission to download it. Thanks!!!

Presentation Transcript

Flower Dissection Activity: 

Flower Dissection Activity

There are two types of plants………: 

There are two types of plants……… plants with seeds and plants without seeds.

Plants without Seeds: 

Plants without Seeds Mosses Liverworts Ferns Horsetails

How do plants reproduce without seeds?: 

How do plants reproduce without seeds? Plants without seeds reproduce through spores that are released into the air.

Life Cycle of Ferns: 

Life Cycle of Ferns The spores are both male and female, so sexual reproduction is taking place.

There are two types of reproduction.: 

There are two types of reproduction. Asexual Reproduction: Requires one cell through divisions of mitosis. Sexual Reproduction: Requires two haploid cells, a male sex cell and a female sex cell, each with half the DNA required to make the new organism. Potato Sprouts Flowering plants with seeds

Plants with Seeds: 

Plants with Seeds Gymnosperms Angiosperms Pine trees, or conifers, are an example of a plant that reproduces by seeds but without flowers. Poppies are a type of flowering plant that reproduce by seeds made by flowers.

Flowering Plants: 

Flowering Plants A flowering plant has both male and female parts. The male part is called the stamen. The female part is called the pistil.

**Please write this definition on your worksheet**: 

Stamen: The male reproductive structure of a flowering plant **Please write this definition on your worksheet**

**Please write this definition on your worksheet**: 

**Please write this definition on your worksheet** Anther: the structure located on top of the stamen and carries the pollen

Pollen: 

Pollen Pollen is the male sex cell that donates half of the DNA to make a seed. It is a powdery substance, usually orange or yellow in color, that gets carried by pollinators.

Pollinators: 

Pollinators A pollinator is something that moves pollen from the male parts to the female parts. Can you name any other pollinators?

**Please write this definition on your worksheet**: 

**Please write this definition on your worksheet** Filament: a thread-like part that holds up the anther

**Please write this definition on your worksheet**: 

**Please write this definition on your worksheet** Pistil: the female reproductive structure of a flowering plant

**Please write this definition on your worksheet**: 

**Please write this definition on your worksheet** Stigma: the sticky surface on the top of the pistil; it traps and holds the pollen

**Please write this definition on your worksheet**: 

**Please write this definition on your worksheet** Style: the tube-like structure that holds up the stigma

**Please write this definition on your worksheet**: 

**Please write this definition on your worksheet** Ovary: the plant part at the bottom of the flower that has ovules inside (this turns into the fruit and seeds we eat)

**Please write this definition on your worksheet**: 

**Please write this definition on your worksheet** Ovules: the female sex cells inside the ovary that donate half the DNA to become the seed (They become the seeds when pollinated or fertilized by the pollen.) A baby seed! 

**Please write this definition on your worksheet**: 

**Please write this definition on your worksheet** Petal: the colorful flower parts that surround the reproductive structures

**Please write this definition on your worksheet**: 

**Please write this definition on your worksheet** Sepal: the green petal-like parts at the base of the flower; they help protect the bud when it develops

**Please write this definition on your worksheet**: 

**Please write this definition on your worksheet** Perfect: flowers that have both male and female parts (ex. Roses, lilies, and pea plants)

**Please write this definition on your worksheet**: 

**Please write this definition on your worksheet** Imperfect: flowers with male or female parts (ex- cucumbers, pumpkins, and melons)

**Please write this definition on your worksheet**: 

**Please write this definition on your worksheet** Pollination: when pollen moves from the male parts to the female parts Watch a bee pollinate a passion flower at http://www.youtube.com/watch?v=AYwAOmcNcCk

Illustrate the Pollination Process: 

Illustrate the Pollination Process http://smithsonlineclassroom.com/media/pollination.mov and illustrate what you see. First, draw two flowers and label the parts of the male and female reproductive structures. 2. Then, watch the pollination animation at

Congratulations!: 

Congratulations! You have just learned about the following California Science Standards in less than an hour: Genetics 2a: the differences between sexual and asexual organisms Genetics 2b: offspring inherit half their genes from each parent Structure and Function of Living Organisms 5f: the structures and processes by which flowering plants generate pollen and ovules, seeds, and fruit.
