Gymnosperms are heterosporous plants. This means that; They reproduce by using one type of spore Their spores are covered with sporopollenin They produce separate male and female spores

Which of the following is not a term used in reference to flowers? corolla sepals O calyx O perianth androecium gynoecium mycorrhizae stamen

In mosses, the sporophyte generation O gives rise to the gametes by meiosis. O has been eliminated. O is dependent on the gametophyte for nutrition. is the prominent generation in the life cycle.

Why, functionally, are parenchyma cells important to fruit function in these species (apples and pears).

The egg and sperm producing strcutures of pteridophytes are found on the gametophyte, also called the

One of the genera of Lycophytes is Selaginella. Like other Lycophytes, Selaginellids bear their spores in a strobilus but they have an unusual strobilus which sets them apart from their relatives. Which answer below best describes this distinction? their spores are always diploid O they are gametophyte-dominant their spores are heterosporous their strobilus is dependnent upon the female gametophyte like mosses

Another distinguishing feature of gymnosperms is that they have resin ducts, which conduct complex chemical compounds such tar, resins and turpentine. What is the function of these three chemicals?

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.
