Chara is an unusual alga. What type of cell division do members of Charophyceae undergo—division with a phycoplast or phragmoplast? What is important about their flagella? Do true plants (especially those with xylem and phloem) have flagella? (Hint: THink sperm cells in ferns and cycads.)
Fungi and animals are both part of a group called Opisthokonta. The vast majority of fungi are multicellular. However, their sister taxon consists of unicellular species. Animals also are multicellular and their closest relatives are again unicellular. Briefly describe the two hypotheses that could explain the origin of multicellularity in the Opisthokonta, and then explain which of the two is the more likely hypothesis
Green algae are believed to be the ancestors of the bryophyte. Cite four distinct lines of evidence to support this belief.

- Both fungi and animals are heterotrophs although they are markedly different in how they acquire nutrients. Explain.arrow_forwardSome fungi can be viewed as coenocytic organisms that exhibit little differentiation. When differentiation does occur, such as in the formation of reproductive structures, it is preceded by septum formation. Why does this occur?arrow_forwardMany people consider algae to be plants even though algae do not have roots, stems, and leaves, but in many algae, cell division is different from that in true plants. Do most algae have a phragmoplast? What is the name of the structure they use?arrow_forward
- Explain at least three important roles for fungi growing in a temperate deciduous forest. What would happen if all the fungi in these forests went extinct? Explain, in detail, why ferns are better adapted for life on land than mosses. Explain how the structure of hyphae (and a mycelium) relates to the function of these cells.arrow_forwardZygomycete bread molds such as Rhizopus stolonifer (black bread mold) produce sporangia in both sexual and asexual reproductive cycles. Which of the following do the sexual sporangia of Rhizopus stolonifer originate from (i.e. what does the sporangia grow out of)? Select one: O a. from the aseptate hyphae O b. from the zygosporangium O c. from the substrate O d. from the gametangiaarrow_forwardWhat is the difference between hyphae called rhizoids and those called stolons?arrow_forward
- Do you think multicellular fungi use diffusion, or use bulk flow, to transport O2 and CO2? Why do you think so?arrow_forwardReproductive structures are the critical factors in distinguishing algae from true plants of kingdom Plantae. What is one fundamental difference between reproductive structures in these two groups?arrow_forwardLichens are said to be composite organisms made up of two very different types of organisms: usually a fungus and an alga (or in a few lichens, a fungus and a Cyanobacterium). (Alga is the singular of algae.) How do these two types of organisms work together to become a functional composite organism? That is, what does each organism provides to the relationship to make it successful? Think about a lichen living on the face of a rock.arrow_forward
- Fungi have an extremely high surface-area-to-volume ratio. What is the advantage of this to an organism that gets most of its nutrition through absorption? O This high ratio means that fungi have a thick, fleshy structure that allows the fungi to store more of the food it absorbs. O The larger surface area allows for more material to be transported through the cell membrane. O This high ratio creates more room inside the cells for additional organelles involved in absorption. O The lower volume prevents the cells from drying out too quickly, which can interfere with absorption. MacBook Pro G Search or typ e URL %23 %2$ % & 3 4 5 8 E R Y F G H.
