Topic 1

• Parts of a plant

  • Stem

    • Support

    • Food storage

    • Transportation (Water + nutrients)

      • Xylem - transports water from roots

      • Phloem - transports nutrients from roots + transports sugar from leaves

  • Roots

    • Absorb water + nutrients

    • Anchors

    • Food storage

• Photosynthesis - To make food by using light

  • CO2 + H2O + energy —> C6H12O6 + O2

  • Green pigment needed for photosynthesis - chlorophyll

• Respiration - breaking down sugars to release energy

  • C6H12O6+O2 —> CO2 + H20 + ENERGY

• Transpiration

  • Loss of water vapor through a living organism

  • Stomata - Opening in leaf

    • Guard cell opens/closes stomata

    • Releases H2O

Topic 2

• Plant reproduction

  • Sexual

    • Genetic material of 2 parents

  • Asexual

    • Single parent - offspring will be identical (clones)

  • Flowers

    • Contain plants reproductive organs

    • Can be male female or both

    • Stamen - Male reproductive organ

      • Anther - pollen(sperm)

      • Filament - stalk supporting anther

    • Pistil - female reproductive organ

      • Stigma - receives pollen

      • Style - tube connecting stigma and ovary

      • Ovary- contains the egg

    • Cross pollinate or self pollinate

• Cross fertilization

  • Pollinators: Insects, birds, animal fur, wind

• Asexual reproduction

• Does not require a mate

• Easier, faster, less energy

• Less variety in traits of offspring (less genetic diversity)

• Deteriorate likelihood of survival

• Sexual reproduction

• Greater variety (more genetic diversity = likelihood of survival goes up)

• Slower, more energy
