Answer 1

Spiny fruits are the fruits that are covered with protective spines, thorns, setae, quills or barbs. Spiny stems are prickly or barbed. The thorns and barbs are themselves called spines. Spina means backbone and thorn or prickle. Red flowers are a symbol of love, passion and energy as red runs through our bodies in raging rivers of blood. It is a symbol of representation and lively imagination.

Complete answer:

($6$) Single-seeded fruits – mango, cherry, peach, plum, litchi, jamun
($7$) Many-seeded fruits – strawberry, watermelon, apple, guava, kiwi, papaya, custard apple.
Single seeded fruit usually has a large single seed. It is derived from a single ovule in the ovary of an individual flower. Many-seeded fruits have been developed from more ovules in the ovary of the flower.

Note:
Yellow flowers are encouraged by December and February rains. Yellow flower represents light-heartedness and joy. It is a symbol of new beginnings, happiness and friendship. They also symbolize optimism and harmony. Plants which close and open their leaves in response to night and day cycles are called nyctinastic. They close to protect pollen and prevent water loss, while the leaves are not performing photosynthesis.
