Parts of Plants and Flowers

What are four MAJOR parts of plants?

• Leave
• Roots
• Stem
• Flower

3
Functions or Jobs

• All plant parts have a purpose
• Collect sunlight and make food (where
  photosynthesis happens)
• Collect water and minerals, hold plant in the
  soil, and store food
• Attract insects and animals in order for the
  plant to reproduce
• Transport water and nutrients throughout the plant

GOOD JOB!!

• The leaves are like the food factories of the
  plant. They make the food for the plant. Have
  you ever noticed how plant leaves will lean
  towards the sun. They are made for collecting
  sunlight for photosynthesis!

9
ALRIGHT!!

• Roots hold the plant in the ground to help
  secure it. Roots also soak up water and minerals
  for the plant. Water is very important and is
  necessary for photosynthesis. Roots are also
  like a cellar for the plant to store extra food.

10
GREAT!!

• Flowers are where the reproductive parts of many
  plants are. They look and smell a particular way
  in order to attract insects and animals who will
  move the pollen and fertilize that plant or
  another plant.

11
YIPEE!!

• The stem is like a bundle of pipes that carries
  water, minerals, food, and other nutrients
  throughout the plants. The xylem carries water
  and minerals up and the phloem carries food and
  nutrients down.

12
Summary

• The four main plant parts and their jobs
• Leaves Collect sunlight and make food (where
  photosynthesis happens)
• Roots Collect water and minerals, hold plant in
  the soil, and store food
• Flowers Attract insects and animals in order for
  the plant to reproduce
• Stems Transport water and nutrients throughout
  the plant

13
Parts of a Flower

• A flower is were the reproductive parts of the
  plant is held. Many parts are inside of a
  flower. The major parts are
• -Stamen -Stigma
• -Pistil -Filament
• -Ovary -Eggs
• -Pollen/Sperm -Anther

14
Male Parts
The male parts of the flower help fertilize the
egg of the flower. These parts are usually in a
place that can be easily moved by insects and
animals. The male parts are the pollen/sperm,
stamen, and filament. Notice that the last two
words have the word men in them. REMEMBER-
MENMALE PART
Pollen
Stamen
Filament
15
What Do you Remember?

• Pollen is the same as _______
• Eggs
• Sperm
• Powder

16
Great!
Pollen is the male sex cell of a flower. Sperm
is another way to refer to pollen.
17
Male Parts Continued

• The stamen is where all the male parts of the
  flower are.

18
Male Parts Continued

• The filament is a tube like structure that holds
  up the anther (a head-like structure) that makes
  the pollen.

filament
19
What do you know?

• Click on the filament

20
Yes!!

• Good job. The filament is a tube-like structure
  that holds up the anther.

21
Uh Oh

• This is a female part called the style. On the
  top is a part called the stigma. We will learn
  about this later in the lesson.

22
Oh no

• This is a female part called the ovary. We will
  learn more about this later in the lesson.

23
Oops..

• This part is called the anther. This is where
  the pollen is made.

24
What do you remember?

• The stamen is the ______
• reproductive part of a flower
• Male
• Female

25
Well Done!

• The stamen is part of the male reproductive
  system of a flower along with the pollen,
  filament and anther.

26
Shucks!

• The male parts are the stamen, pollen, anther
  and filament. Notice that
• two words have the word men in them.
• REMEMBER- MENMALE PART

27
The Female Reproductive Organs

• The pistil is the term for all the female parts
  of a flower. Each pistil includes an ovary (where
  the eggs are produced the female reproductive
  cells, a style (a tube on top of the ovary), and
  a stigma (which the pollen sticks to during
  fertilization).

Where is the stigma?
Click on the part of the flower that shows the
stigma.
29
Nope

• This is a petal. This is used for attracting
  insects and animals.

30
Uh Oh

• This is a female part called the style. This is
  where the pollen tube will be formed.

31
Oh no

• This is a female part called the ovary. Here is
  where the eggs are stored and what will change
  into the fruit that we eat.

32
Rats

• This is the part of the ovary where the eggs are
  stored.

33
Good Job!

• The stigma is on top of the style. It is sticky
  so that the pollen grains will stick to it.

Tough Break

• Look closely at the arrows and the words...you
  can do it.

You got it!!

• Well done!

41
Not exactly

• This is tricky double check the word order

42
Fertilization

• Pollen must join with an egg to produce a seed.
  This process is called pollination, and is often
  helped by animals like bees, which fly from
  flower to flower collecting sweet nectar. As they
  visit flowers, they spread pollen around, leaving
  it on some stigmas. After a male's pollen grains
  have landed on the stigma during fertilization,
  pollen tubes develop within the style, burrowing
  down to the ovary, where the sperm fertilizes an
  egg cell. After fertilization, this develops into
  a seed in the ovary.

43
What forms in the style during fertilization?

• Pollen grain
• Pollen tubes
• Pollen allergies

44
Not quite

• Pollen grains are individual pollen cells.

45
Bummer

• Flowers dont have allergies, as far as I know.

46
Terrific!!

• Lets move on to a summary

47
Fertilization summary

• Once the pollen lands on the stigma, the pollen
  grain burrows down the style by making a pollen
  tube until it reaches where the eggs are stored
  in the ovary. The pollen and egg join together
  to form a seed (baby plant). The ovary ripens
  and becomes the fruit that we eat.
