Chapter 30, Problem 7TYU
EVOLUTION CONNECTION The history of life has been punctuated by several mass extinctions. For example, the irnpact of a meteorite may have wlped out most of the dinosaurs and many forms of marine life at the end of the Cretaceous pcriod (see Concept 25.4). Fossils indicatc that plants were less severely affectcd by this mass extinction. What adaptations may have enabled plants to withstand this disaster bctter than animals?

thinking about the evolution of life on earth, why do you think plantsexisted before animal life and how are the two life forms connected today that supportseach other’s survival? Be specific. (hint: tie in Aerobic Respiration and Photosynthesis)

- Suppose you wanted to make a science fiction film in which human time travelers went back to the carboniferous. What types of modern plants would you use and which would you avoid if you wanted to depict the carboniferous setting as accurately as possible?arrow_forwardBIOMES & ADAPTIVE RADIATION Adaptive Radiation ven the type of biome these succulent plants are found in, identify 3 important stressors present in their environments. Now, describe how these pressures likely influenced the diversification of these plant lineages. Use one of the plant families listed above (and your representative species) to discuss as an example. (A well-developed paragraph is expected.)arrow_forwardSUBJECT: GENERAL BIOLOGY 1 / CAM and C4 Photosynthesis Plant adaptation is varied among all organisms present on Earth’s fauna. Also, we can’t deny the fact that as time goes by, the amount of carbon rises making it more complicated for the rest of organisms to adapt and survive. In relation to their specialized features, predict how C4 and CAM plants will each respond to a doubling of the concentration of CO2 in the atmosphere.arrow_forward

Today, the most diverse group of plantsis the________ .arrow_forwardThe earliest fossils clearly recognizable as parts of flowering plants are _____________________ __________________ in rocks more than ______________ million years old.arrow_forwardSCIENTIFIC INQUIRY Herbivory (plant eating) has evolvedrepeatedly in insects, typically from meat-eating or detritusfeeding ancestors (detritus is dead organic matter). Moths andbutterflies, for example, eat plants, whereas their “sister group”(the insect group to which they are most closely related), thecaddisflies, feed on animals, fungi, or detritus. As illustrated in the following phylogenetic tree, the combined moth/butterflyand caddisfly group shares a common ancestor with flies andfleas. Like caddisflies, flies and fleas are thought to have evolvedfrom ancestors that did not eat plants. There are 140,000 species of moths and butterflies and 7,000species of caddisflies. State a hypothesis about the impact ofherbivory on adaptive radiations in insects. How could thishypothesis be tested?arrow_forward

- Insect-Assisted Fertilization in Moss Moss sperm can swim, but plant ecologist Nils Cronberg suspected that they sometimes hitch a ride on crawling insects or mites (tiny animals related to spiders). To test this hypothesis he carried out an experiment. He placed patches of male and female moss gametophytes in dishes, either next to one another or with water-absorbing plaster between them. The plaster prevented sperm from Swimming between plants. He then looked at how the presence or absence of insects affected the number of sporophytes formed. FIGURE 22.8 shows his results. FIGURE 22.8 Sporophyte production in female moss patches with and without either crawling insects (springtails) or mites. No Sporophytes formed in the animal-free dishes when moss patches were 2 or 4 centimeters apart Why is sporophyte formation a good way to determine if fertilization occurred?arrow_forwardAnswer the folowing quetions below; 1. In cacti the leaves ar modified into spine. Give some reasons why the cacti underwent such modification. 2. In pitcher plant the leaves terminate into pitcher like structures. What special functions does this specialized structure serve the whole plant?arrow_forwardSCIENTIFIC INQUIRY A plant biologist observed a peculiarpattern when a tropical shrub was attacked by caterpillars.After a caterpillar ate a leaf, it would skip over nearby leaves andattack a leaf some distance away. Simply removing a leaf didnot deter caterpillars from eating nearby leaves. The biologistsuspected that an insect-damaged leaf sent out a chemicalthat signaled nearby leaves. How could the researcher test thishypothesis?arrow_forward
