Title: Flower Dissection Activity

FlowerDissectionActivity
2
There are two types of plants
  • plants with seeds and
  • plants without seeds.

3
Plants without Seeds
Mosses
Liverworts
Horsetails
Ferns
4
How do plants reproduce without seeds?
  • Plants without seeds reproduce through spores
    that are released into the air.

5
Life Cycle of Ferns
The spores are both male and female, so
reproduction is taking place.
6
There are two types of reproduction.
  • Type one Requires one cell through divisions of
    mitosis.
  • Type two Requires two cells, a male cell and a
    female cell, each with half the DNA required to
    make the new organism.

Flowering 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.
8
Flowering Plants
  • A flowering plant has both male and female parts.

The female part is called the pistil.
The male part is called the stamen.
9
Please write this definition on your worksheet
  • Stamen The male structure of a flowering plant

10
Please write this definition on your worksheet
  • Anther the structure located on top of the
    stamen and carries the pollen

11
Pollen
  • Pollen is a powdery substance, usually orange or
    yellow in color, that gets carried by
    pollinators.

.
12
Pollinators
  • A pollinator is something that moves pollen from
    the male parts to the female parts.

Can you name any other pollinators?
13
Please write this definition on your worksheet
  • Filament a thread-like part that holds up the
    anther

14
Please write this definition on your worksheet
  • Pistil the female structure of a flowering plant

15
Please write this definition on your worksheet
  • Stigma the sticky surface on the top of the
    pistil it traps and holds the pollen

16
Please write this definition on your worksheet
  • Style the tube-like structure that holds up the
    stigma

17
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)

18
Please write this definition on your worksheet
Petal the colorful flower parts that surround
the reproductive structures
19
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

20
Please write this definition on your worksheet
  • Perfect flowers that have both male and female
    parts (ex. Roses, lilies, and pea plants)

21
Please write this definition on your worksheet
  • Pollination when pollen moves from the male
    parts to the female parts

22
Illustrate the Pollination Process
  1. First, draw two flowers and label the parts of
    the male and female structures.

2. Then, watch the pollination animation at

n.mov and illustrate what you see.

Good-bye!
