The Plant Kingdom

Explore the fascinating world of plants, the autotrophic eukaryotes that create their own food through the process of photosynthesis. Learn about essential plant structures like chloroplasts, cell walls, and vacuoles, and how they contribute to water and nutrient absorption. Discover the complex life cycles of plants, featuring sporophyte and gametophyte stages, and the roles of vascular tissues such as xylem and phloem in transporting vital substances. Uncover the secrets of chlorophyll and its role in capturing light energy.

Presentation Transcript

  1. The Plant Kingdom Chapters 4.1 and 4.2

  2. Ch. 4.1 and 4.2 Plants and PhotosynthesisTake notes for each number • Plants are autotrophs-makes their own food

  3. Ch. 4.1 and 4.2 Plants and PhotosynthesisTake notes for each number 2. Plants are eukaryotes-have a nucleus

  4. Ch. 4.1 and 4.2 Plants and PhotosynthesisTake notes for each number 3. Plants are sun-powered, food-making factories

  5. Plantsuse photosynthesis Sunlight powers the whole process

  6. Plants have • cell walls-cell boundary • cellulose-chemical makes cell rigid • chloroplasts-where food is made • chlorophyll-green light-trapping molecule • vacuoles-sack-like storage area • Photosynthesis

  7. 6. Plants must • obtain water/nutrients • retain water • transport materials • support bodies • reproduce

  8. 7. Plants have complex life cycles 2 stages • Sporophyte-producing spores • Gametophyte-2 sex cells or gametes

  9. 8. Plants use Chlorophyll : -most abundant pigment a) reflects green light b) absorbs other colors c) hides fall colors Photosynthesis begins when light strikes the plant

  10. Got Celery? What does celery have to do with plants?

  11. What is a vascular plant? • Has vascular tissue • Inner tube-like structures • Water and food move throughout • Strengthens plant’s body • Grows tall • Transports substances to distant cells

  12. 2 types of vascular tissue • Phloem (floh um) • Tissue moving food • Travels to stem and roots • Xylem (zy lum) • Tissue moves water, nutrients

  13. Chloroplast Nucleus Vacuole Cell wall
