Answer 1

The correct option is A 1, 2 only

Explanation:

• Pneumatophores and Vivipary physiological modifications are found in Mangroves. Pneumatophores and vivipary are adaptations to survive in saline and water-logged conditions.
• Thrones and long taproots are present in desert plants.
• Pneumatophores: Some plants that grow in swampy areas have roots growing vertically upwards to get oxygen for respiration such roots are known as pneumatophores. Pneumatophores can only be found in mangrove trees, such as Ceriops sp, Heritiera domes. Such roots have many tiny pores on their surface, through which they can absorb oxygen and release carbon dioxide.
• Vivipary: Vivipary refers to a seed that germinates into a seedling before being shed from the parent plant.
