The basic features of ferns and their relative plants which differ them from other organisms or plants so far. Introduction: Pteridophytes are the vascular plants. They bear leaves (which are known as fronds), roots and sometimes the true stems. The tree ferns have the full trunks. For example, ferns, horsetails, and club-mosses. The Pteridophytes are having ferns and fern allies. The fern allies are a broad group of seedless vascular plants which are not true ferns.

The basic features of ferns and their relative plants which differ them from other organisms or plants so far.

Introduction:

Pteridophytes are the vascular plants. They bear leaves (which are known as fronds), roots and sometimes the true stems. The tree ferns have the full trunks. For example, ferns, horsetails, and club-mosses. The Pteridophytes are having ferns and fern allies. The fern allies are a broad group of seedless vascular plants which are not true ferns.

Expert Solution & Answer

Explanation of Solution

The difference between pteridophytes and other plants is explained as follows:

Ferns are exceptional among the land plants. These have two different living structures in their reproductive cycle (the gametophyte and the sporophyte). When sporangia release these spores, then they land in a favorable environment. They can grow into a small plant which is known as the gametophyte. Whereas, in the flowering plants, other vascular plants, and conifers, the adult plant grows directly from the seeds. The ferns usually reproduce from the spores with an intermediate plant stage (gametophyte).

Conclusion

Thus, the basic difference between the pteridophytes and other plants (like flowering plants, other vascular plants, conifers) is that ferns have gametophyte and sporophyte which is absent in the later.

Use the following information to answer the question(s) below. Martin Wikelski and L. Michael Romero (Body size, performance and fitness in Galápagos marine iguanas, Integrative and Comparative Biology 43 [2003]:376-86) measured the snout-to-vent (anus) length of Galápagos marine iguanas and observed the percent survival of different-sized animals, all of the same age. The graph shows the log snout-vent length (SVL, a measure of overall body size) plotted against the percent survival of these different size classes for males and females. Survival (%) 100- 80- 60- 40- 20- 0+ 1.9 T 2 2.1 2.2 2.3 2.4 2.5 2.6 2.7 Log SVL (mm) 19) Examine the figure above. What type of selection for body size appears to be occurring in these marine iguanas? A) directional selection B) stabilizing selection C) disruptive selection D) You cannot determine the type of selection from the above information. 3

24) Use the following information to answer the question below. Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. They identify the gene responsible for toxin production. The dominant allele (T) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. Heterozygotes produce an intermediate amount of toxin. The genotypes of all individuals in the population are determined (see table) and used to determine the actual allele frequencies in the population. TT 0.49 Tt 0.42 tt 0.09 Refer to the table above. Is this population in Hardy-Weinberg equilibrium? A) Yes. C) No; there are more homozygotes than expected. B) No; there are more heterozygotes than expected. D) It is impossible to tell.
