  1. Honors BiologyModule 14 Kingdom Plantae: Anatomy and Classification March 27,2014

  2. Notebook check today Through module 13 I will also be collecting lab books at the end of today’s class.

  3. March 27, 2014 - Quiz 24 Indicate with arrows  the direction of blood flow into and out of the human heart. Can you name and identify all of the arteries and veins ?

  4. Blood Flow through the heart

  5. Kingdom Plantae: Anatomy and Classification Botany: Is the study of plants There are many ways to look at and analyze plants.

  6. Determine if they are…. Woody (Perennial): It has trunks and/or woody stems and it typically grows year after year. Annual (herbaceous): These plants do not have woody parts and they typically live for only one year.

  7. Biennial: Plants that live for two years. Typically they store food during the first season of growth and then reproduce in the second season.

  8. When you begin to study plants They have certain organs and tissues. They can be classified into two groups: • Vegetative organs: the parts of a plant (stems, roots and leaves) that are not involved in reproduction, • Reproductive plant organs: The parts of a plant (flowers, fruits and seeds) involved in reproduction.

  9. Is a tomato a fruit or vegetable? Clue: If a food item is a reproductive plant organ, it is a fruit. If it is a vegetative organ, it is a vegetable. So, what is it?

  10. A tomato is a fruit !!! Many of the foods we call “vegetables” are seeds or containers of seeds (peas, corn) Vegetative edibles: Carrots (roots), lettuce, celery

  11. Plants have 4 basic kinds of tisssues • Meristematic tissue: contains cells that are undifferentiated (cells that have not specialized in any particular function). They can develop through mitosis into any tissue that the plant needs.

  12. 2. Ground tissue: is the most common plant tissue. These cells provide storage for starches and oils that the plant needs. Other ground tissue provides for metabolism through photosynthesis. Also cells for ground tissue help to support the plant.

  13. 3. Dermal tissue: This is generally made out of a single layer of cells. It protects the plant by providing a shield between the environment and the plant’s internal tissues. This shield can stop many pathogenic bacterial and fungi. It can also prevent needed chemicals inside the plant from leaking out into the environment. The dermal tissue in the roots of a plant is also responsible for absorbing water and minerals that the plant needs.

  14. 4. Vascular tissue: This is not present in all plants. However, the majority of plants have it. It is used to carry water and dissolved material (minerals) throughout the plant. (Think of it as the same as blood vessels in animals) A. Xylem: nonliving vascular tissue that carries water and dissolved minerals from the roots of a plant and its leaves. (Cells have thicker walls and cells die after they mature) B. Phloem: Living vascular tissue that carries sugar and organic substances throughout the plant. (Cells continue to live after they mature)

  15. Major parts of a LeafFigure 14.1

  16. Simple and Compound LeavesFigure 14.2 A simple leaf is one leaf attached to the stem by a single petiole. A compound leaf has several leaflets attached to a single petiole.

  17. Leaf Arrangement

  18. 3 Main Leaf Mosaics Figure 14.3 The arrangement of leaves on the stem

  19. Botanists classify leaves using 3 characteristics: Shape, margin and venation

  20. Common Leaf ShapesFigure 14.4

  21. Leaf MarginsFigure 14.5

  22. Leaf VenationsFigure 14.6
