Summary Introduction
Introduction:
Plants belong to kingdom plantae and are multicellular and autotrophic eukaryotes. They can make their own food by the process of photosynthesis, as they contain chloroplast, which captures light energy to make glucose. Plants include gymnosperms, flowering plants, conifers, hornworts, mosses, green algae, liverworts, and mosses.

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.)
The kingdom Plantae constitutes large and varied groups of organisms. There are more than 300,000 species of identified and cataloged plants. Using the geologic record, discuss and explain when and how plants colonized the land. Include the adaptations that enabled them to survive on land amid the harsh environmental conditions.
Which of the following evidences would BEST determine whether two plant species share a recent common ancestor?
Group of answer choices
seed development
fossil record
DNA sequences
habitat distribution

Like these green algae, plants have a life cycle called the alternation of generations. Draw a diagram of the basic life cycle of a plant, showing the alternation of the sporophyte and gametophyte generations. Unlike green algae that live in water, plants live on land. Being surrounded by air means that they risk losing too much water through evaporation and dying from dehydration. Name 3 characteristics of plants that help them conserve water and protect them from drying.arrow_forwardWhich of the following is a universal feature of the life cycles of land plants? Genetically identical gametophyte and sporophyte stages Multicellular haploid and diploid gametes Morphologically identical gametophyte and sporophyte stages Alteration of generations between haploid gametophytes and diploid sporophytesarrow_forward
- Most of the carbon that land plants use for photosynthesis comes from ______. a. glucose b. the atmosphere c. water d. soilarrow_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_forwardPlants made the leap from water to land during the late Ordovician period (we think). In order to make it, various physical obstacles had to be overcome. Choose one adaptation and explore it further. What evidence do we have of this change? Are there specific fossils of plants that exhibit it? How do we think it may have developed? Not all of these changes occurred at the exact same time. Was your chosen adaptation one of the first or late to the game? including references are appreciated.arrow_forward
