label 11.2 and 11.3 3. Now examine a prepared slide of a Psilotren stem cross Section Notice the epidermis with its well-developed cuticle. Stomata are present here as well. The cortex is relatively large and has three regions. Beneath the epidermis is a region of parenchyma cells that contain chloroplasts (chlorenchyma). Adjacent to the chloren- chyma is typically a zone of sclerenchyma cells that give the stem support. The innermost portion of the cortex consists of another region of parenchyma...
1. Label the microphylls and strobili in the Figure 1 below. Figure 1. Lycopodium sp. Examine the prepared slide of a mature Lycopodium strobilus. (See text Figure 17-16, pages 406 and 407.) Note that Lycopodium, like most species in the Lycopodiaceae, is homosperous and only produces one type of spore 2. Label the spores in Figure 2 below. Figure 2. Lycopodium strobilus 1.s. 3. Given that Lycopodium is homosporaus, would you expect its gametophytes to be unisexual or bisexual? Explain...
