  2. Plants are Alive • Just like people and animals. • How do we know this? Living things all do certain things: • They grow and die.
They need energy, nutrients, air, and water.
They produce young.
They are made up of cells.
They react to what's around them.

  3. Autotrophs • Plants make their own food via Photosynthesis

  4. cells • Plants are eukaryotic • Cells have cell walls, chloroplasts, and large central vacuole

  5. Levels of organization • Cells make up tissues, tissues make up organs, organs make up organ systems, organ systems make up organisms • Stems, leaves, roots are organs • 2 organ systems: shoot system, root system

  6. Adaptations • Plants have adaptations that allow them to live on land: • Roots to obtain water and nutrients • Cuticle- waxy covering on leaves to help retain water • Vascular tissue inside plant for movement of water, minerals, and food • Vascular tissue and cell walls for support • Reproductive adaptations

  7. Asexual Reproduction • Some plants can undergo asexual reproduction called vegetative reproduction • Pieces of parent plant breaks off and develops into new plant

  8. Sexual Reproduction • ALL plants undergo sexual reproduction involving fertilization (the joining of sperm and egg) • Fertilized egg = zygote

  9. Complex Life Cycle • 2 stages • Sporophyte stage produces spores that grow into the stage 2 organism, the gametophyte which produces gametes
