Plant Fertilization

Important Notes to Know: 

• Germinated pollen descends down the pollen tube into the ovule.
• Pollen nucleus will fertilize the ovule which leads to the formation of a zygote.
• The zygote will grow into the embryonic plant.
• Outside the ovule the seed coat will start to grow.
• Cotyledons are the food storage for the seedlings. 
• The walls of the ovaries start to thicken. Sugar and proteins are stored in this thick wall.
• This forms the fruit which is developed from the wall of the ovary/carpel.

Wind pollonation

Important Things to Know

• The wind blows it, this spreads the seeds of the plants.
• Wherever the seeds land is where they will grow. Unfortunate seeds might land near a tall tree and will not receive enough sunlight to grow.
• The seed that are attached to the plant is attached weakly so it can easily break off when the wind hits it.
• These types of plants are not usually attractive or brightly colored.

Insect Pollination

Important Things to Know

• Insect pollination when a plant is fertilized through a insect. 
• The plant attracts insects to land on the flower by a scent.
• The insect lands on the flower to drink the nectar in side the flower.
• While the Insect is drinking the nectar the pollon is stuck to the insect .
• The insect then goes arround to other plants the pollon is then dropped into the plants stigma, this fertilizes the plant.
