They are perigynous when apparently borne on the ovary. 4.The parts of the ovary wall on which the ovules are borne is called locules. 5.Dry fruit may be indehiscent when endocarp does not split at maturity.
- Now examine the demonstration slide of a c.s. of an immature lily anther and identify the four pollen sacs, or microsporangia (see text Figure 19-14a, page 466). Note the layer of cells immediately surrounding the microspore mother cells (microsporocytes, or pollen mother cells). This is the tapetum. 3. Label the pollen sacs and microsporocytes in Figure 2. below. Figure 2. Lilium immature anther c.s. Photo by Carolyn Alling 4.
