Double Fertilization | Biology for Majors II types of sperm in plants


Sperm is the male reproductive cell. In the types of sexual reproduction known as anisogamy . In flowering plants, sperm nuclei are produced inside pollen.

In animals, an ovum or egg fuses with a motile sperm, generating the .. that a plant has no species-specific gamete recognition mechanisms.

Because the sperm of flowering plants have no flagella, they do not Although we include data from pollen tubes of different species (e.g.

ities exist among cytoskeletons of nonflagellated and flagellated sperm? How can we explain the loss of fla- gella? If sperm of flowering plants are reduced forms.

The plant life cycle has mitosis occurring in spores, produced by meiosis, that germinate into the gametophyte phase. within an antheridium (producing sperm) and/or archegonium (producing eggs). . This distance is species specific.
