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.
