  1. Plants

  2. What roles do plants serve in the ecosystem • Oxygen • Food • Reduce soil erosion • Medicines

  3. How plant differ from animal • Plants produce their own food with the aid of nutrients from the soil. • Plants are stationary. • Plants have rigid cell walls with cell membranes inside. • Plants utilize carbon dioxide and give off oxygen.

  4. List how plants and animals are alike. • Plants and animals are alike in several ways. • They have a life cycle. • They carry on life processes, such as circulation, respiration and growth. • They are made of cells. • They must have food.

  5. List three major factors that affect plant growth • Temperature • Precipitation • Light

  6. Define life cycle in terms of plants and how they are classified • Life Cycle: refers to the length of the plant’s life. • Plants can be classified into three groups on the basis of their life cycle: • Annuals- complete life within one year. • Biennials- complete life cycle in two years. • Perennials- plants live for more than two years. • Deciduous- plants that lose their leaves in the winter. • Evergreens- plants that retain their leaves year round.

  7. List the different parts of a plant • Leaves- makes food for the plant through a process known as photosynthesis. • Blade -Veins • Epidermis -Stomata • Internal cells -Waxy coating • Petiole -Stipule

  8. Waxy Coating Stomata Stipule Stipule Petiole Petiole Vein

  9. List the two different types of leaves • Simple • Compound

  10. Simple Leaf

  11. Compound Leaf

  12. Objective 1.8List the three ways leaves attach to the stem • Leaves attach to the stem in several different ways. • Alternate • Opposite • Whorled

  13. AlternateAttachment

  14. Opposite Attachment

  15. Whorled Attachment

  16. List the different functions of the stem • The stem supports the leaves and flowers. • The stem transport water and other materials. • The stems also store food.

  17. List the different parts of the stem • Bark • Cortex • Phloem • Cambium • Xylem • Pith

  18. Xylem & Pholem

  19. List the types and roles of roots • Role of roots • Roots anchor the plant. • Roots take in water and minerals. • Roots store energy. • Types of roots • Taproots • Fibrous roots

  20. Taproot

  21. Fibrous Root

  22. Taproot vs. Fibrous
