  1. Parts of a Plant

  2. Living Things • All living things grow and change. • All living things need food, water, and air to live.

  3. Nonliving Things • Nonliving things are not alive. • Nonliving things do not need food, water, or air.

  4. Plants must have these things to grow. • Sunlight • Air • Water • Nutrients or minerals from the soil

  5. When a seed has sunlight, air, water, and nutrients it will begin to germinate, or start to grow. This young plant that grows from a seed is called a seedling.

  6. Parts of a Plant • Roots hold the plant in the soil and takes in water and nutrients from the soil.

  7. Parts of a Plant • The stem holds up the plant and moves water and nutrients through it.

  8. Parts of a Plant • Leaves use light, air, water, and nutrients to make food for the plant.

  9. Parts of a Plant • Flowers make fruits that hold seeds. Flower 

  10. Seed Coat Seed Leaf Stored Food Developing Plant Parts of a Seed

  11. Seed Coat The hard covering that protects the seed is the ... The part that looks like a leaf inside each seed is the ... Seed Leaf

  12. Seeds • Seeds are formed in the center part of the flower or fruit. • Seeds come in many shapes and sizes. • Plants grow from seeds.

  13. Planting Animals Water Wind How Seeds Are Scattered

  14. The life of a plant begins as a seed. Once you plant and water a seed it begins to germinate. The root pushes through the seed coat. The seedling grows out of the ground. The stem and its leaves point to the sunlight. The leaves make its own food. Flowers begin to bloom and make seeds. New seeds are formed and scattered. What is this process called? How a Seed Grows into a New Plant

  15. The Life Cycle of a Plant

  16. Life Cycle of a Plant

  17. PHOTOSYNTHESIS • Autotrophic Process: Plants and plant-like organisms make their energy (glucose) from sunlight. • Stored as carbohydrate in their bodies. • 6CO2 + 6H2O + sunlight  C6H12O6 + 6O2

  18. Why is Photosynthesis important? • Makes organic molecules (glucose) out of inorganic materials (carbon dioxide and water). • It begins all food chains/webs. Thus all life is supported by this process. • It also makes oxygen gas!!

  19. Photosynthesis-starts to ecological food webs!

  20. Photo-synthesis means"putting together with light." • Plants use sunlight to turn water and carbon dioxide into glucose. Glucose is a kind of sugar. • Plants use glucose as food for energy and as a building block for growing. • Autotrophs make glucose and heterotrophs are consumers of it.

  21. How do we know that plants make carbohydrates from just carbon dioxide water and light energy? Experiments! • For example: Jan Baptisa van Helmont (1648) planted a willow branch weighing 5 pounds into 200 pounds of soil and then after 4 years the tree weighed 169 lbs. and the soil was still nearly 200 lbs.

  22. As can be seen from the equation for photosynthesis, the wood, bark, and root came from water and carbon dioxide. Photosynthesis Carbon dioxide + water glucose + oxygen sunlight absorbed by chlorophyll 6CO2 + 6H2O + energy  C6H12O6+ 6O2

  23. Plants in Action Check it! What is the process that uses the sun’s energy to make simple sugars?

  24. Remember… When the small plant inside begins to grow, the seed germinates. The young plant that grows from a seed is the seedling. Seeds are scattered by planting, wind, water, and animals.

  25. Experiment • Question – what will you test • Hypothesis – If then because • Control Group – Under normal conditions • Experimental Group – Your test group • Write a procedure

  26. Let’s Review! • What do all living things need to live and grow?

  27. 1. All living things need _____. foodwaterair

  28. 2. Can you name the parts of a plant?

  29. 2. The parts of a plant are the _____. rootsstemleavesflower

  30. 3. What do plants need to grow?

  31. 3. Plants need ____ to live and grow. sunlight air water nutrients or minerals from the soil

  32. 4. What do the roots do for a plant?

  33. 4. The roots hold a plant in place and takes in water and nutrients from the soil.

  34. 5. What does the stem do for a plant?

  35. 5. The stem holds up the plant and moves water and nutrients through it.

  36. 6. Why does a plant need leaves?

  37. 6. Leaves use sunlight, air, water, and nutrients to make food for the plant.

  38. 7. What do flowers do for a plant?

  39. 7. Flowers make fruits that hold seeds. These seeds will make new plants.

  40. 8. How can seeds be scattered?

  41. 8. Seeds can be scattered by _____. • planting • animals • water • wind

  42. Congratulations! You have learned all about plants, seeds, and a plant’s life cycle.
