Flower

Flower Anatomy and Development

• Etymology traces flower terminology evolution
• Morphology details vegetative and reproductive parts
• Perianth components and variations in floral structure
• Development stages from shoot to meristem to inflorescence
• Transition to flowering and genetic models for organ development

Reproductive Function of Flowers

• Reproductive parts like androecium and gynoecium
• Heterosporous nature producing microspores and megaspores
• Pollination process involving sperm transfer for reproduction
• ABC model genes responsible for flower development
• Loss of gene function leading to aberrant flower development

Pollination Mechanisms and Relationships

• Biotic and abiotic pollination methods
• Cross-pollination vs. self-pollination impacts
• Pollinator relationships and coevolution with flowers
• Attractant methods like mimicry, nectar production, and color
• Specific pollinator relationships crucial for plant survival

Self-Pollination and Preventing Self-Pollination

• Self-pollination benefits and drawbacks
• Allergenicity of pollen and its impact on human health
• Fertilization process involving synagmy and double fertilization
• Strategic self-pollination in plants like Clianthus Puniceus
• Mechanisms to prevent self-pollination for genetic diversity

Environmental Impact and Adaptations

• Climate change increasing pollen production and allergenicity
• Fertilization process from pollen transfer to zygote formation
• Strategic adaptations like self-pollination in absence of pollinators
• Methods to prevent self-pollination for genetic diversity
• Importance of pollination for plant reproduction and survival
