  1. Kingdom Plantae

  2. Characteristics of All Plants Photosynthesis Cellulose Lack Mobility

  3. Vascular vs. Non-Vascular Non-Vascular Vascular Terrestrial plants (most don’t depend on H20 for PS) Able to transport nutrients via transport system Vascular system provides support enabling them to grow larger Examples: ferns, herbs, shrubs, trees, flowering plants • Water habitats (needed for reproduction) • No internal transport systems • Live close to ground • Examples: mosses, liverworts, hornworts

  4. Vascular are divided into two groups… Seedless Plants Seed Plants Reproduce by seeds Adaptation for terrestrial life E.g. Flowering plants, trees, crops • Reproduce by spores • Need water for reproduction • E.g. Ferns

  5. Seed plants are divided into two groups… Gymnosperms “vessel” >250, 000 different kinds Success of angiosperms due to insect/flower relationship Seed is contained within a “vessel” called a fruit E.g. crops, deciduous trees, flowering plants Angiosperms • “naked” • Cones are reproductive structure • Male cone = pollen • Female cone = ovule • Thin needle-like leaves covered with a waxy cuticle (adaptation for hot/dry summer and cold winters) • E.g. Pine, spruce, junipers, fir

  6. Seed plants are divided into two groups… • Research the difference between these two groups. Include: • Examples • Number of cotyledons • Number of seed leaves • Arrangement of vascular bundles • Type of veination on leaves • Arrangement of floral parts Monocots Dicots

  7. To do… • Dissect a corn seed and a bean seed • Label the following parts: seed coat, endosperm, cotelydon(s), hypocotyl, epicotyl • Determine whether each seed is a monocot or dicot and why you think so.
