    Some seeds also show chalaza (place of origin of seed coats) and raphe (part of funiculus fused with seed wall) The embryo consists of an axis or tigellum to which are attached one (in monocotyledonous seeds) or two (in dicotyledonous seeds) seed leaves or cotyledons
  • Seeds: Definition and Structure (With Diagram) - Biology Discussion

  • Sexual Reproduction in Angiosperm Plants (Steps) - Biology Discussion
    On the basis of position of micropyle, with respect to the funiculus, ovules are 6 types: 1 Orthotropous ovule: It is atropous or straight, where the micropyle, chalaza and the funiculus, all are in the same line Ex- Cycas, Family Polygonaceae and Piperaceae 2 Anatropous ovule: It is of the most common occurrence more than 80% of angiosperm
