Germination: Mycelia form. There are two mating types (+ and –). Mating type Dispersal and germination Mycelia (_n) - Mating type Process 2 Fusion between Cell division: Four + and – mating types results in formation of a dikaryotic mycelium. Sexual Reproduction basidiospores are formed. Basidium with four nuclei Ln) Process 1 Four haploid nuclei are formed in the basidium. Process 3 Under the right environmental conditions, a basidiocarp forms. Gills of the basidiocarp contain cells called basidia. Zygote Karyogamy: Basidia form Basidia diploid nuclei. Basidiocarp

Which statement about life cycles with a dikaryon stage is false? A zygosporangium results from the fusion of two coenocytic hyphae. In effect, the dikaryon is neither diploid nor haploid. Dikaryotic hyphae often have characteristics that are different from those of their n or 2n products. The only true diploid structure is the zygote. There are no gamete cells, only gamete nuclei.

Label the parts (number 1-4) of the diagram showing the life cycle of a Lycopodium sp. Indicate whether each of the labeled part is haploid (n) or diploid (2n).

What material makes up a large proportion of a diatom’s cell wall? What material makes up a large proportion of a diatom’s cell wall? What are flagella? What purpose do flagella serve? What do euglenoids have instead of a cell wall? What characteristics do plantlike protists share with plants? How do euglenoids obtain food when there isn’t enough light to perform photosynthesis? How do dinoflagellates compare and contrast with euglenoids? How do algae get food to live?

Fill in the spaces with one of the following terms: haploid, diploid or dikaryotic: The gills of a mushroom are _______________ . When the mushroom is first formed, a basidium is _______________ . Following karyogamy, a basidium is _______________.The basidium then undergoes meiosis, which produces _______________ spores.

Select all the true statements about Euglena they can eat other organisms for food they do photosynthesis to make their own food they have green pigments they move using cilia they move using pseudopods they move using flagella a 99+
