What part of the flower has sperm cells?
After pollen grains have landed on the stigma, pollen tubes develop, and burrow down into the ovary, there the pollen (sperm cell) fertilizes an ovule (egg cell). After fertilization, the ovule develops into a seed. In contrast to the idealized diagram above flowers actually are quite varied in appearance.
Where are sperm produced in plants?
antheridium
The sporophyte phase produces spores by meiosis within a sporangium. The gametophyte phase produces gametes by mitosis within an antheridium (producing sperm) and/or archegonium (producing eggs). Within the plant kingdom the dominance of phases varies.
What type of flower has only male or female parts?
