The fleshy center of the watermelon is made up of mesocarp and endocarp, and it has a thick rind. The watermelon fruit, which is informally categorized as a type of melon, has a smooth external green and yellow rind and a juicy, sweet interior flesh that is typically red or yellow but can occasionally be orange. On the same plant, the plants generate separate male and female flowers, and the female blooms have smaller ovaries. The fruit’s flesh is made up of highly developed placental tissue.
Since watermelon contains a lot of lycopene, it is particularly good at preventing cell damage and may help reduce the risk of heart disease.
