Pollination mechanisms and types

Double fertilization in angiosperms

Post-fertilization: Seed and fruit development

Apomixis and polyembryony

‍

🎯 Key Formulas

Key Processes & Steps

Microsporogenesis → Pollen grain formation
Megasporogenesis → Embryo sac formation
Double Fertilization:
- Sperm 1 + Egg cell → Zygote (2n)
- Sperm 2 + Central cell → Endosperm (3n)
Seed formation stages

⚠️ Common Mistakes to Avoid

Confusing microsporogenesis and megasporogenesis

Mixing up the products of double fertilization

Misunderstanding the role of endosperm

Incorrect identification of flower parts

Confusing various types of pollination

‍

📖 Knowledge Prerequisites

Plant cell structure

Basic plant anatomy

Cell division (mitosis/meiosis)

Plant tissue types

‍

💡 Tips for Students

Draw and label flower structure repeatedly

Create flowcharts for reproductive processes

Make comparison tables for different types of pollination

Use mnemonics for remembering sequential steps

Focus on understanding rather than memorizing

‍
