What is a Plant Practice Questions

1. a. Plants are not able to move from one spot to another, although they can produce seeds that are easily dispersed from one spot to another. The other answers are characteristics that plants do exhibit and that separate plants from other organisms.

2. c. Liverworts and mosses are the most common representatives of the bryophytes that are plants that do not possess a vascular system. Horsetails and ferns are seedless vascular plants, and spruce trees are nonflowering seed plants.

3. d. Angiosperms, the flowering seed plants, are the dominant plant species. The other categories have many representatives and are quite successful in more limited habitats.

4. d. Racheophyte refers to plants with tubes or a vascular system. Nonvascular plants (the bryophytes: mosses and liverworts) are not tracheophytes. Angiosperms (flowering seed plants) and gymnosperms (nonflowering seed plants) are both tracheophytes.

5. c. Angiosperm (flowering) plants produce nectar, pollen, and fruit, which animals are attracted to as food sources. In the process of gathering or consuming these foods, the animal pollinators will be assisting in the plant's reproductive process. Chloroplasts are used in photosynthesis and not to attract animals.

6. c. Bryophytes are nonvascular plants that do not have actual roots but root-like structures called rhizoids.
