A banana contains both a fleshy endocarp and mesocarp but the exocarp is skin-like. Bananas also cannot expel their seeds thr dehiscence. Which type of fruit is a banana? Pepo Berry Hesperidium Drupe

sporangiophores are interpreted as modified branches and consist of a stalk and a shield- like portion. Inside of the sporangium, look for the spores each with a pair of elongated appendages called elaters. These elaters respond to changes in the humidity to aid in spore dispersal. 18. Label the spores on Figure 6 below. Figure 6. Equisetum strobilius l.s. Equisetum is homosporous and produces green, free-living, bisexual gametophytes. (See text Figure 17-40 and 17-41, page 425-427.) Photo by Carolyn Alling Fill in Table 1 from the Bryophyte lab with information about Lycophytes, Ferns, and Horsetails. 97

In the mature angiosperm seed, the nutritive tissue is triploid. This tissue is formed from; Two polar nucleii fusing with a sperm cell The synergids fusing with a sperm cell The sperm fusing with the egg cell The embryo

When the hyphae of two compatible club mushrooms (Basidiomycota) fuse, the result is hyphae that is; Diploid N + N Соenocytic Нaploid

The female gametophyte of the moss, seen in the photo below (Ls. at 40x and then at 100 xl, shows that the tip contains the structures where female gametes (eges) are produced Make a sketch of the slide at 100x and label the following structures: archegonial head, archegonium (neck, venter, eg termat

Are gymnosperms heterosporous or homosporous?  Explain what this means.  What are the evolutionary “advances” represented by the seed?

Why are gymnosperms nicknamed "naked seeds?" Because they originate from an egg cell only, rather than an egg cell and a sperm cell. Because they are not encased by the mature ovary. Because they originate from a sperm cell only, rather than an egg cell and a sperm cell. Because they are encased by a protective sheath.

Which of the following processes occurs in a plant's sexual life cycle?       sporophytes produce gametes by meiosis     sporophytes produce gametes by mitosis     gametophytes produce gametes by meiosis     gametophytes produce gametes by mitosis

Female gametophytes develop specifically within what part of the pine cone? -Pollen sac -Anther -Central cell -Microsporangium -Ovule
