    1. Parts of Plants and Flowers

    2. What are four MAJOR parts of plants?

    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

    4. Which is Which #1? Click on the word that matches the function Which part collects sunlight and makes food (where does photosynthesis happen?)

    5. #2 Which part collects water and minerals, holds the plant in the soil, and stores food?

    6. #3 Which part attracts insects and animals in order for the plant to reproduce?

    7. #4 Which part transports water and nutrients throughout the plant?

    8. 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

    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

    15. What Do you Remember? Pollen is the same as _______ Eggs Sperm Powder

    16. Great!

    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.

    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- “MEN”=MALE 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).

    28. Where is 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.

    34. Review Click on the correct picture of the MALE reproductive parts.

    35. Oops… Check the order of the words…

    36. Not Quite Check the order of the words…

    37. Great!! You got it!

    38. Click on the correct picture of the FEMALE reproductive parts

    39. Tough Break Look closely at the arrows and the words...you can do it.

    40. 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 don’t have allergies, as far as I know.

    46. Terrific!! Let’s 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.
