No Comments on Epithelium or Epithelial Tissue

Science > Biology > Zoology > Histology > Epithelium or Epithelial Tissue In this article, we shall study about the epithelium or epithelial tissue. Higher-level organisms have multicellular structure. The cells differ from one another in their shape, size. Cells arise from pre-existing cells by the process of cell division. In multicellular organisms, cells are […]

Fertilization

Science > Biology > Botany > Reproduction in Plants > Fertilization In last article, we have studied about pollination and its types. In this article, we shall study the process of fertilization. Out Breeding Devices: Most angiosperms produce bisexual flowers (hermaphrodite). But most of them avoid self-pollination naturally or we can say that in plants […]
