Is it true that the type of reproduction observed in angiosperms is both unisexual and bisexual?
 

The production of male or female gametes on separate plants is referred to as unisexual reproduction. Some angiosperms are monoecious, with separate male and female flowers on the same plant, whereas others are dioecious, with either male or female flowers on separate plants.

The production of both male and female gametes in the same flower is referred to as bisexual reproduction. The majority of angiosperms have bisexual flowers with both male and female reproductive structures. These flowers can self-pollinate or cross-pollinate with other flowers of the same or different plant, resulting in ovule fertilisation and seed production.
