Plants

• Xylem

  Transports water and minerals up from the root and into the leaf
• Phloem

  Moves substances produced by photosynthesis
• Transfer of substances in the Phloem

  Translocation
• Phloem

  The living tissue which carries nutrients
• Xylem

  The living tissue that carries water
• Root system

  • Absorbs water and minerals from the ground
• Stem

  • Provides structural support to hold up the plant
• Transpiration

  The process of water cooling the plant
• Leaves

  • Main functions are photosynthesis and gas exchange
• Types of plant tropisms

  • Phototropism - light
  • Thigmotropism - touch
  • Hydrotropism - water
  • Geotropism - gravity
• Carpel

  Consists of the style, stigma and ovaries
• Pollination

  When pollen and nectar is moved around from one plant to another
• Agents of pollination

  • Birds
  • Small mammals
  • Insects
• Stigma

  Sticky to catch pollen
• Flowers

  • Need nectar, petals and scent to attract pollinating agents
• Independent variable

  What is
• Dependent variable

  What is controlled
• Angiosperms are the only plants that produce flowers</b>
• Unisexual plants are either male or female, while bisexual plants are both</b>
• Plant transport tissues

  Xylem and phloem
• Photosynthesis

  Carbon dioxide + water + sunlight -> glucose + oxygen
• Leaves

  • The main part where photosynthesis takes place
• Plants are known as autotrophs as they can produce their own food
• Leaf

  • The large surface area helps absorb as much sunlight as possible
• Stomata

  Tiny openings that allow carbon dioxide to enter and oxygen to exit
• Chlorophyll

  The green pigment in plants that absorbs light
• Stamen

  The male part of the flower
• Ovary

  The female part of the flower
• Stamen

  Consists of the anther and the filament
