1. Warm-up 2-22-06 Do you think you could survive on this planet without plants? Explain..

2. The Energy Pyramid

4. Autotrophs An autotroph is an organism that can produce their own food Plants are autotrophs because they make their own food using sunlight - their cells are designed for this, as they have chloroplasts, an organelle that only plant cells have

5. Heterotrophs An organism that cannot make their own food is called a heterotroph. Examples: people, rabbits, lady bugs, birds, dogs, cats, etc…

6. The caterpillar is a heterotroph. To live, grow, and perform other caterpillar functions it needs energy from the plant’s sugars.

7. Caterpillars are heterotrophs

8. Caterpillar eating a leaf..

9. So how do plants make their own food? In a process called photosynthesis

10. PHOTOSYNTHESIS

11. Plants take up carbon dioxide (CO2) and release oxygen (O2) back into the air Humans breathe in oxygen and breathe out carbon dioxide

12. Plant Cell

13. Chloroplasts- site of photosynthesis; this is where energy from sunlight is captured to make food for the plant

14. Carnivore- an animal that eats meat only Herbivore- an animal that eats only plants Omnivore- an animal that eats both plants and animals

16. Energy Pyramid

17. So, do you think you could survive on this earth without plants? Explain..

18. Did you get it? Plants are ______because they make their own food. Plants are autotrophs because they make their own food.

19. A cow is an example of a/an__________because it cannot make its own food. A cow is a heterotroph because it cannot make its own food. It needs to eat plants to get energy to survive.

20. Photosynthesis takes place in the_____________. chloroplasts

21. A bird eating a ladybug that nibbles on a leaf of a plant, is an example of a _______ consumer. secondary consumer

22. What three things are needed for photosynthesis to take place? sunlight, water, and carbon dioxide

23. Add to your flip packet Autotrophs Heterotrophs Photosynthesis Carnivore, omnivore, and herbivore Energy Pyramid

24. 1.Flips must include definitions. 2.Flips must include a sentence using the word. 3.Flips must include a picture representing the word. 4.Flips need to have color and be neat. -5 points for each of the criteria

25. Objectives To distinguish between the male and female parts of a flowering plant To understand what is pollination and how to know the ways in which plants are pollinated

26. Types of Plants Seed Plants Gymnosperms are tree shrubs that do not have flowers Angiosperms are plants that have flowers and seeds that are protected by fruit Seedless Plants Seedless vascular plants, example- fern, horsetails, and club mosses Non vascular plants such as liverworts and hornworts

27. Pollination Pollination is when the pollen is released from the anther and fertilizes the ovule in the ovaries

28. Anthers contain pollen (sperm) and the ovary contains the egg

29. Reproductive Parts Male Filament- holds the anthers Pollen-found in the anthers; contains sperm Anthers- tip of the filament- contains pollen Female Stigma- sticky part that traps in pollen and pulls it downward Style- part of the plant that pollen travels down to reach the egg Ovule- becomes the seed when fertilized by sperm in pollen Ovary- stores the ovule;part of the flowert hat develops into the fruit

31. A fruit is a ripened ovary that encloses one or more seeds..

32. How is a plant pollinated? 1.People can transfer pollen from one flower to another, but most plants pollinate without the help from people. 2. Usually they rely on animals, such as birds, bees, flies, and other insects to pollinate them.

33. The animals don’t mean to pollinate the plants- it happens accidentally. When they go to the base of the petal to get food (nectar) some of the sticky pollen rubs off on them, and they carry it with them to the next plant they feed off of. Then some of the pollen on them can rub off onto the stigma of another plant and fertilize its ovules.

34. Bees pollinating a flower..

35. A butterfly looking for nectar.. will pollinate a flower without knowing it.

36. Energy Pyramid

37. The zygote then begins to develop into the seeds embryo As the seed develops, the ovary changes into the fruit

38. What are the male parts of a plant? What are the female parts of a plant? Which part of the plant becomes the fruit? What is pollination? Explain..
