Tapetum lucidum is a layer of tissue in the eye of many vertebrates and some other animals that reflects light back to the retina, enhancing night vision. Learn about its function, mechanism, classification, and variation in different species, such as dogs, cats, birds, and spiders.
Learn about the tapetum, a reflective layer in the eye that improves vision in dim light and causes eyes to shine in some animals. Find chapters and articles from various scientific books and journals on tapetum structure, function, and variations.
The meaning of TAPETUM is any of various reflective membranous layers or areas especially of the choroid and retina of the eye.
The functions of tapetum entail the supply of nutrition and enzymes essential for the process of microsporogenesis and the successive development of pollen grains. This article discusses how the tapetum contributes significantly to the reproductive success of flowering plants, its types, and the functions it performs.
Learn about tapetum, the deepest layer of the anther that produces pollen and provides nutrition. Find out the types of tapetum, such as secretory and amoeboid, and their functions in pollen development.
On either side of the corpus callosum, the fibers radiate in the white substance and pass to the various parts of the cerebral cortex; those curving forward from the genu into the frontal lobe constitute the forceps anterior, and those curving backward into the occipital lobe, the forceps posterior. Between these two parts is the main body of the fibers which constitute the tapetum and extend ...
Discover key tapetum functions in plants and eyes. Ace exams with Vedantu's expert notes, diagrams, and quick summaries.
tapetum The food-rich layer of cells that surrounds the spore mother cells in vascular plants. In some plants it breaks down to form a fluid termed the periplasmodium, which is absorbed by the developing microspores. In others the tapetum remains intact until shortly before anther dehiscence and secretes substances into the locule.
Tapetum is the innermost layer of cells in the anther that provides nutrition and support to the pollen grains. Learn about its structure, types (amoeboid and glandular), and functions (food conduction, exine formation, pollenkitt secretion) with examples and references.
Tapetum is a layer of nutritive cells in the anther of flowering plants that supports pollen development. Learn about its types, functions, and evolution in different plant groups.
