To what major group of fungi does Agaricus belong? 2. Describe or draw the reproductive cycle of a basidiomycota. 3. Fungi reproduce by spores. How are spores structurally different from seeds? Is a spore produces asexually or sexually in the fungal groups we looked at? (Trick question) 4. How are spores dispersed? 5. Is it autotrophic or heterotrophic? Explain how you know. 6. When we look at a mushroom we are not looking at the main body of the fungi. only at the reproductive fruiting body. Wliere is the main part of the organism? 7. Why doesn't the mushroom have any green leaves? 8. Each year a group of mushrooms grow on the school lawn. They are destroyed when the lawn is mowed for the first time cach year. Yet each year they continue to grow in the same place. Explain why. 9. Where are the spores produced?

Answer 1

1. Agaricus belongs to major group Basidiomycetes in kingsom Fungi.

2.

3. In terms of cellular complexity seeds are superior because ther are multicellular while spores are unicellular.Spores are the first cell of gametophyte while, seeds contain within them a developing embryo produced by the fusion of male gamete.

4.The Basidiospores in this order of fungi are forcibly ejected from the basidium, into the area between the lamellar edges, which then allows the spores to fall free from the mushroom and be dispersed by wind.

5.Fungi are heterotrophic - they obtain their organic material from external sources, their environment. They have no chlorophyll; they are not green in color.
6.Mushrooms have two main parts – the fruiting body and the mycelium. Of these tha main part is mycelium.

7.The mushroom does not have green leaves because it does not have chlorphyll.
8.When the spores land in a suitable location they develop into new fungi-which will grow mushrooms given enough time. Mushrooms will go away on their own once the weather dries out. Keep in mind that although these fruiting bodies have disappeared, the fungal mycelia is still growing in the soil.

9.In the Basidiomycetes, the spores are produced externally, on the end of specialised cells called basidia.
