FOCUS ON EVOLUTION
The history of life has been punctuated by several mass extinctions. For example, the impact of a meteorite may have wiped out most of the dinosaurs and many forms of marine life at the end of the Cretaceous period (see Figure 23.12). Fossils indicate that plants were less severely affected by this mass extinction. What adaptations may have enabled plants to withstand this disaster better than animals?

- BIOMES & 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_forwardSome ancestral plants had a difficult transition to land, as challenges to survive caused plant evolution to develop very specialized adaptations over an extended amount of time. These are some of the challenges that plants faced: A. Avoiding desiccation B. Supporting larger bodies (against gravity) C Internally transporting substances D. Keeping gametes wet E. Keeping embryos wet For each of the above challenges. provide a structure/adaptation that plants have developed which mitigates that specific challenge. Must describe a structure or trait for all!arrow_forwardUnique characteristics of plants : Which of the following are unique characteristics of plants? (Check all that apply) are multicellular are prokaryotes are unicellular are eukaryotes store food as starch store food as glycogen V carry out photosynthesis carry out cellular respiration M have cell walls made up of cellulose have cell walls made up of chitin have multicellular embryos have unicellular embryos alternate between two generationsarrow_forward

- Charophytes are the group of green algae whose ancestral lineage gave rise to land plants. Life on land comes with several challenges not required for life submerged in water. What are these challenges and how did land plants overcome them? 3 challenges that land plants overcame as they adapted to land at least 1 key adaptive characteristic that allowed them to overcome each challenge. Also, include which lineage of land plants first evolved each characteristic you state.arrow_forwardLike many multicellular organisms, plants have organs that perform specific functionsWhich of the following correctly pairs a plant organ with its function?

- What evidence do paleobotanists look for that indicates the movement of plants from water to land? O sporopollenin to inhibit evaporation from leaves O loss of structures that produce spores O remnants of chloroplasts from photosynthesizing cells O waxy cuticle to decrease evaporation from leaves MacBook Pro G Search or type URL %23 % & 3 4 6. 7 W E R Y G C V * 00 B (O ト D.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_forwardA new "plant" is found to lack vascular tissue, have a dominant gametophyte generation, and swimming sperm. What would you expect the "plant" to look like? O A. Short and with needles and cones for reproduction. O B. Small, green, spread out over a large area, and live in moist environments. O C. Tall and leafy. The great surface area of the leaves would allow for much photosynthesis & make up for the lack of vascular tissue. O D. E) Filamentous cells that live in water and are heterotrophic parasites of amphibians and fishes A Moving to another question will save this response. «< Question 8 of 120 » 11:54 AM 12/16/2020 Del PrtScn F8 Home F9 End F10 PgUp PgDn F12 F11 DIl FS F7 F6 F4 F3 F2 Backspace & % %3D # 2$ 9. 7 2 3 4 T.
