Everyday

2. Fertilisation is also putting fertiliser on soil to help plants grow. tree →

In the lessons

In science lessons on plant life cycles: pollination, then fertilisation, then seed formation, then seed dispersal, then germination. In animals, fertilisation happens when a sperm joins an egg. In gardening and farming, fertilisation of soil feeds crops. Phrases: «after fertilisation», «pollination and fertilisation».

Examples

• After pollination, fertilisation happens inside the flower. tree →
• Fertilisation makes the flower's ovule grow into a seed. tree →
• In frogs, fertilisation happens in the water. tree →
• Draw the life cycle: germination, growth, pollination, fertilisation. tree →
• Too much fertilisation of fields can pollute rivers. tree →
• Bees help with pollination, which leads to fertilisation. tree →

Note

British spelling «fertilisation», American «fertilization»; both are correct. Verb: «fertilise» / «fertilize». Trap: pollination (pollen moves to another flower) comes before fertilisation (cells join); they are not the same. Not a number word.
