Is stamen present in grape vine?

No, stamens are not present in grape vines (Vitis vinifera) as they are functionally female and do not produce viable male reproductive structures. This is because grapevines are monoecious plants, meaning they have separate male and female flowers on the same plant. However, the flowers of grape vines are typically functionally female, and even though they may have rudimentary male parts such as stamens, these are often not functional or viable for producing pollen. Grape vines produce small, inconspicuous flowers that consist of four greenish-white petals and four to five stamens. However, the stamens are typically non-functional and do not produce viable pollen.
