39
Q

difference of fruits and vegetables

A

Fruits are mature ovaries containing seeds, often formed from the fertilized ovule, while vegetables are edible plant parts such as roots, leaves, or stems.

40
Q

importance of fruits in plant reproduction

A

Fruits are crucial in plant reproduction as they protect and disperse seeds. They develop from mature ovaries, containing seeds formed after fertilization. Animals are attracted to the fruit, eat it, and disperse the seeds, promoting the plant’s distribution and ensuring genetic diversity.
