  1. Plant Cells and Tissues

  2. Meristematic Cells • Plants have meristematic cells which are plant stem cells. • They are found at the tips of roots and branches as well as in the stem (see fig.2.4 on p.59) • Meristematic cells produce specialized cells.

  3. Plant Tissues • 3 types of tissues in plants • Dermal tissue • Forms the outer covering of plants • Offers protection and controls the exchange of water and gases between the plant and the environment • Ground Tissue • Several functions such as photosynthesis or support for plant body • Vascular Tissue • Provides physical support • Transports sap

  4. Photosynthesis • Occurs in the chloroplast • Chlorophyll is a green molecule that absorbs light energy Carbon dioxide + water + light energy  glucose + oxygen

  5. Your task Read 2.1 pp.57-69 Fill in handout on plant tissues Answer questions: 1, 2,4-7 p. 69 Move on to Plant organ handout
