Life Cycle Of Bryophytes

A group of plant species that utilize spores, instead of flowers or seeds, for reproduction is known as a bryophyte. The non-vascular seedless plants which include mosses, liverworts, and hornworts are classified as bryophytes. There are over 20,000 spec…

Plant Biometry

Biometry is the science that deals with the statistical investigation of biological observations and phenomena. It is very important in the development of sound and effective agricultural research practices. It is a Greek-derived word wherein 'bio' means…

Life Cycle Of Gymnosperms

Gymnosperms, which translates to "naked seeds," are a diverse group of seed plants. The angiosperms are a sister group to one group of gymnosperms (the Gnetales), making the gymnosperms a paraphyletic group, according to the "anthophyte" hypothesis. The …

Life Cycle Of Pteridophytes

They are the first land plants with vascular tissues (xylem and phloem). These vascular plants are classified as vascular cryptogams because they do not contain flowers or seeds. These plants are the most common and visible group of land plants, accounti…

Life Cycle Of Angiosperms

An angiosperm is a word obtained from the two Greek words angio, which refers to "covered," and sperms, which means "bean". Flowering plants are what the angiosperms are called. The flowers of a plant develop into fruits, which contain seeds.

Textbook Question

Chapter 45.6, Problem 3TC

Heat-producing flowers are rare, and many are members of evolutionary ancient groups. Some botanists hypothesize that warmth was an early adaptation that attracted beetle pollinators. Today, most plants do not have warm flowers, but supply their pollinators with a sip of nectar. Develop a hypothesis to explain why the more recently evolved “fast-food” flowers predominate today.

As you learned in this chapter, many prescription drugs are derived from natural plant products. Numerous other plant substances, including caffeine and nicotine, have effects in the human body, as well. There is also a wide array of plant products, in the form of pills, powders, or teas, marketed as herbal medicines. Some people prefer taking these “natural” products to pharmaceuticals. Others use herbal supplements to boost energy, promote weight loss, strengthen the immune system, relieve stress, and more. The U.S. Federal Drug Administration, which approves pharmaceuticals, is also responsible for regulating herbal remedies. What does the label “FDA-approved” on an herbal remedy mean? How does that compare to FDA approval of a drug? The FDA website http://www.fda.gov/ForConsumers/default.htm is a good place to start your research. (Note that the FDA classifies herbal remedies as dietary supplements.)

Ferns are a type of terrestrial plant that does not produce seeds, unlike gymnosperms and flowering plants. This significant evolutionary divergence contributed to the dominance of gymnosperms and flowering plants. How might the ability to produce seeds have advantaged these groups? It allowed these plants to photosynthesize more efficiently. It allowed these plants to attract more pollinators. It allowed these plants to better disperse, colonize new habitats, and survive drier conditions. It allowed these plants to grow taller and compete for sunlight.
