Explanation

• Apomixis: Seed formation without fertilization, meaning the fusion of male and female gametes does not occur.
• The offspring are often genetically identical to the parent plant because the seed develops without normal sexual reproduction.

Additional information:

• Parthenocarpy: Fruit development without fertilization; it commonly produces seedless fruits.
• Grafting: A vegetative propagation method in which parts of two plants are joined.
• Scion: The shoot or stem piece joined to the rootstock during grafting.

Explanation

• Leaves are called the food factory of plants.
• They prepare food through the process of Photosynthesis.
• Chlorophyll in leaves absorbs sunlight to make food.
• Photosynthesis uses Carbon dioxide (CO₂), Water (H₂O), and Sunlight.
• Food produced is mainly Glucose, which provides energy to the plant.
