pollination

• how many types of pollination are there

  there are two types of pollination: cross-pollination and self-pollination
• what is cross-pollination

  pollen from one individual lands on the female part of a different individual: pollen comes from anther and lands on the stigma: cross-pollination only happens on the same species
• what is self-pollination

  pollen from the same individual lands on the female parts
• why does self-pollination happen

  because plants have both male and female parts
• can all flowers self-pollinate

  no, not all can, this may be because there is a physical barrier between the male and female parts or separate male or female parts
• what are wind-pollinated flowers

  plants that rely on wind to transfer pollen from the male part; the anther to the female part; stigma
• what are insect-pollinated flowers

  plants that rely on insects - such as bees, butterflies, flies, etc - to transfer pollen between different flowers
• which is a wind-pollinated flower and which is an insect-pollinated flower

  A is the insect-pollinated flower and B is the wind-pollinated flower

  
• how are insect-pollinated flowers adapted for

  bees are more attracted to these types of flowers: colours, smell, nectar

  strong filaments means its easier for insects to collect pollen
• how are wind-pollinated flowers adapted for

  wind causes cross-contamination because the anther and stigma hang out

  petal makes it easier for wind to blow pollen

  feather-like stigma is light-weight and pollen is caught easier
• what is the cons of insect-pollinated flowers

  sticky pollen isn't sufficient because making it means you need more resources you may not want to use, meaning you get less pollen
• what are the cons of wind-pollinated flowers

  pollen is light so not that many resources are needed so you get more pollen however it isn't as sticky
