Depends on the definition of "closed flower".
If you mean a flower that is enclosed with petals which are open, such as an Orchid, then the answer would be yes. This happens with many different types of flowers, some which have special adaptations to target a specific insect pollinator.
If you mean a closed flower that has not yet opened, then the answer is almost definitely no. When the petals are closed and folded together the stigma and anthers are not yet mature; this means that even if an insect were able to get between the closed petals there sex organs of the flower would not yet be receptive to pollination.
Generally insect pollination takes place in open flowers but there are specific cases of insect pollination in closed flowers as in case of many species of Ficus, Lotus etc.
self -pollination occurs within the same flower or same plant
Pollination occurs when the pollens from the anther of a flower is transferred to the stigma of the same or another flower. This is of two types- Self-Pollination(when the pollens from the anther of a flower are transferred to the stigma of the same flower or plant) and Cross-Pollination( when it gets transferred to the stigma of flower on another plant). Pollination is brought about by the help of various factors like insects, birds,wind, water.
In order for pollination to occur, what must happen to the pollen grains is that they have to be transferred to the stigma in a flower of the same species. The stigma is the female part of the flower.
Insect pollinated is attractive and colourful, the former isn't Besides petal color the insect pollinated flowers also have insect attracting smell where as in wind pollinated flowers the petals are neither attractive nor scented.
Yes, The Ovary contains the Ovules, which, when pollinated, turn into the seed.

The flower is to attract insects and bees, etc, and aid in cross-pollination for seeds to develop. If cross-pollination doesn't take place, there will still be a flower, but no seeds will develop.

the differences between a unisexual and a bisexual flower is unisexual flower- the flower may either contain stamen or a carpel. cross pollination takes place in such kinds bisexual flower - such flowers contain both stamen and carpels . there are chances of cross pollination and self pollination in such flowers.
