Tricolporate pollen of rose flower
Numéro d’image : 11539269
| Rose pollen. Coloured scanning electron micrograph (SEM) of tricolporate pollen grains of a Garden Rose,Rosa sp. Pollen grains are the male sexual spores that are discharged from the male part of the flower. They contain the gamete that ferti- lizes the female ovule to form a seed. Pollen grains are classified according to a number of features: pores (porate),furrows (colpate),or both (colporate). Rose pollen has three furrows from each of which protrudes a bulge or pore (as seen here). They are thus "tricolporate". Rose plants are insect pollinated,relying on insects to carry the pollen to the female flower structures. Magnification: x1,035 at 5x7cm size. Magnification: x2,550 at 12x16cm size | |
