Q: What is the rigid layer that is found outside the cell membrane and surrounds the cell? Read this paragraph and choose the correct option from the provided answers: A cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell. The cell wall contains not only cellulose and protein, but other polysaccharides as well. In fact, two other classes of polysaccharides, hemicelluloses and pectic polysaccharides, can comprise 30% of the dry mass of the cell wall. The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell. Choices: - cell barrier - cell shield - cell root - cell wall A:
cell wall

Read this paragraph and choose the correct option from the provided answers: Figure 24.16 Which of the following statements is true? a. A basidium is the fruiting body of a mushroomproducing fungus, and it forms four basidiocarps. The result of the plasmogamy step is four basidiospores. Karyogamy results directly in the formation of mycelia. A basidiocarp is the fruiting body of a mushroom-producing fungus. Figure 24.20 If symbiotic fungi are absent from the soil, what impact do you think this would have on plant growth?. Choices: - schizonts - tunnels - fossiliferous - basidiocarps A:
