| These animals typically contain abundant populations of rods in their retinas, which are often found in conjunction with a retinal tapetum. |
|
| The receptors have long fused rhabdoms and are surrounded by a tracheal tapetum. |
|
| In a number of species, regardless of their wall formation type, new periclinal cell divisions may occur when the tapetum differentiates. |
|
| The tapetum degenerates earlier than usual, resulting in high pollen sterility, and anther indehiscence occurs when pollen stainability falls below 20 percent. |
|
| At the stage of tetrad, the anther wall was composed of epidermis, endothecium and tapetum. |
|
| Deer also have a tapetum lucidum, which gives them sufficiently good night vision. |
|
| The single cell layer of tapetum surrounding the anther loculus is first recognizable at the early Microsporocyte stage. |
|
| This provides a mirrorlike surface, the tapetum lucidum, which reflects light outward and thereby allows a second chance for its absorption by visual pigments at very low light intensities. |
|
| Parietal tapetum cells keep their individuality and position lining the locules throughout their entire life cycle. |
|
| On the back wall of the eye, the tapetum lucidum reflects incoming light, thus utilizing the small amount of light available at night to best advantage. |
|
| Strepsirrhines have a reflective layer, the tapetum lucidum, behind the retina, which increases the amount of light for night vision, while haplorrhines have no tapetum but, instead, an area of enhanced vision, the fovea. |
|
| Exine and Intine are formed in this stage and tapetum in this plant is plasmodial type. |
|
| The eyes are located at the sides of the head and have a tapetum lucidum, or reflecting membrane, at the back of the retina, which aids vision in dim light. |
|
| On maturation of the anther, the sporangial wall consists of the epidermis and the endothecium, whereas the middle layers and tapetum disintegrate. |

| Relationships between tapetum, loculus, and pollen during development. |

| Plasmodial tapetum and pollen wall development in Butomus umbellatus. |
|
| The choroid is very thick and contains a fibrous tapetum lucidum. |
