Anatropous Ovule, Biology Class 12 Important Diagrams

Each ovule develops within the ovary, connected to the placenta by a small stalk known as the funiculus. The point where the funiculus attaches to the main body of the ovule is termed the hilum. In angiosperms, the prevalent ovule type is anatropous, with the micropyle directed downward and situated next to the funiculus (funicle). … Read more

Structure of Anther, Biology Class 12 Important Diagram

The immature stage of an anther is characterized by a parenchymatous tissue group enclosed by a single-layered epidermis. Anthers are typically dithecous (with two lobes) and tetrasporangiate. A monothecous anther holds two pollen sacs, while a dithecous anther has four, making it tetrasporangiate. Heterogeneity in differentiation occurs when certain hypodermal cells undergo transformation into archesporial … Read more
