Initial phase of fertilisation in Arabidopsis thaliana, or mouse-ear cress, observed using a scanning microscope. A tetrad of pollen grains has been deposited onto the stigmatic papillae of a pistil. It can be seen that two of these grains are starting to germinate. Next, the pollen grains will form a pollen tube that will insert itself into the pistil to bring the sperm nucleus into contact with the ovule nucleus. Through these experiments, research scientists study meiosis, the specialised…

Initial phase of fertilisation in Arabidopsis thaliana, or mouse-ear cress, observed using a scanning microscope and artificially coloured. A tetrad of pollen grains has been deposited onto the stigmatic papillae of a pistil. It can be seen that two of these grains are starting to germinate. Next, the pollen grains will form a pollen tube that will insert itself into the pistil to bring the sperm nucleus into contact with the ovule nucleus.
