Strange sex tube

But when the tube encounters too much tightening force from the tissue, pollen tube bursts and releases sperm. The pollen tube swells up like an inflating balloon, navigating a narrow channel to deliver sperm to the ovules, where it fertilizes an egg cell. Growing Pollen Tube Credit: Scientists captured the delicate act in these amazing microscope images. Anja Geitmann, University of Montreal Plant reproduction and its human counterpart aren't all that different, a new study detailed in April in the journal Proceedings of the National Academy of Sciences suggests. She received a graduate certificate in science communication from the University of California, Santa Cruz, and a bachelor of science in biomedical engineering from Brown University.

Anja Geitmann, University of Montreal Close-up top view of the stigma and anthers, or the part of the stamen where pollen gets produced, of a Camellia flower. Anja Geitmann, University of Montreal Here's how the researchers think plant sex goes down in the Camillia plant: Spewing Sperm Cargo Credit: Scoop on Sex Credit: Growing pollen tube Credit: Persistent pollen tube Credit: Anja Geitmann, University of Montreal Here a loook at the pollen grains of the Camellia flower attached to a stigma. But when the opening was too narrow, the tubes simply burst — spewing their precious sperm cargo. One sperm cell fertilizes the egg cell. Anja Geitmann, University of Montreal A pollen tube before and after bursting and releasing its onboard sperm cells. The other sperm cell fertilizes the central cell of the same ovule to give rise to the endosperm, a tissue the nourishes the growing embryo. Anja Geitmann, University of Montreal Anja Geitmann, a biologist at the University of Montreal in Canada, wondered how a plant's pollen tube generates the forces necessary to penetrate surrounding cells that resist its growth. Anja Geitmann, University of Montreal Here, a pollen tube growing through a microscopic gap of the microfluidic device, helping researchers understand how a pollen tubes drills through the tissue of a female plant. Anja Geitmann, University of Montreal Scanning electron micrograph of two germinated lily pollen grains with pollen tubes false-colored. Tanya has lived on a tropical island, witnessed volcanic eruptions and flown in zero gravity without losing her lunch! Anja Geitmann, University of Montreal Close-up side view of the stigma and anthers of a Camellia flower. The pollen tube swells up like an inflating balloon, navigating a narrow channel to deliver sperm to the ovules, where it fertilizes an egg cell. Scientists captured the delicate act in these amazing microscope images. Anja Geitmann, University of Montreal Detail of a lily pollen grain with an emerging pollen tube scanning electron micrograph. When a pollen grain, which stores plant sperm, lands on top of the stigma, a structure that sits atop the carpel where the female sex cells are stored, the pollen grows a long tube that pushes through the surrounding tissue. To find out, the researchers developed a special chip shown here to measure the forces a pollen tube encounters as it grows.
