The plant tissue type that gives rise to all other plant tissues or cell types is: A) meristem D) protodermis B) ground tissue E) epidermis C) vascular tissue ____ 2. According to physiological evidence and some genetic data, which of the following has the best chance of actually being a grade that would form a clade with flowering plants? A) phylum Cycadophyta D) phylum Ginkgophyta B) phylum Gnetophyta E) phylum Coniferophyta C) phylum Anthophyta ____ 3. For most plants, the preferred soil type is a mix of mineral types that hold water well but not too well. This type of soil is called: A) fallow D) sand B) clay E) loam C) humus ____ 4. A plant with long, tubular red flowers that have little or no odor is most likely pollinated by: A) flies D) moths B) bees E) birds C) butterflies ____ 5. Some plants, such as legumes, have specialized root nodules where bacteria live in a mutualistic symbiotic relationship with the plant. These bacteria help mainly by: A) digesting insects that the plant has captured B) assisting with the uptake of water by the plant C) assisting with micronutrient uptake by the plant D) converting phosphorous to a form that the plant can use E) fixing nitrogen into compounds that the plant can use ____ 6. Members of this phylum are found mostly in freshwater. They have a ciliated food-gathering organ at the tip of their head called a corona. The beating of the cilia gives the appearance of a turning wheel. Some members of this phylum make extensive use of parthenogenesis for reproduction. A) Rotifera (rotifers) D) Cnideria (stinging-celled animals) B) Porifera (sponges) E) Ctenophora (comb jellies or sea walnuts) C) Nemertea (ribbon worms) ____ 7. Seed coats, which functions to protect plant embryos and allow them to stay dormant, are formed by: A) 3N cells from the endosperm B) 2N cells from the sporophyte that gave rise to the female gametophyte parent C) 1N cells from the sporophyte that gave rise to the female gametophyte parent D) 2N cells from the embryo E) 1N cells from the female gametophyte parent ____ 8. A long-day plant will flower if A) it is kept in continuous far-red light. B) the duration of continuous light exceeds a critical length. C) the duration of continuous darkness exceeds a critical length. D) the duration of continuous light is less than a critical length.
