Ch 14

Within the plant kingdom, relative to the gymnosperms, the angiosperm species are:

• monophyletic.

• more evolutionarily advanced.

• non-vascular.

• seedless.

• more multicellular.

The dry, waxy layer that covers the leaves and stems of plants is known as the:

• roots.

• vasculature.

• cuticle.

• prothallus.

• sporangia.

In what order do the following taxa appear in the fossil record?

• invertebrates; fish; land plants; amphibians

• invertebrates; amphibians; fish; land plants

• land plants; invertebrates; amphibians; fish

• land plants; invertebrates; fish; amphibians

• invertebrates; fish; amphibians; land plants

In the life cycle of a non-flowering, non-seed plant (fern), the process of meiosis produces:

• gametes.

• diploid cells.

• eggs.

• spores.

• pollen.

Which is the best brief description of the vascular system of the very first terrestrial plants?

• The first plants developed specialized vessel cells that conducted water.

• The first plants did not develop a vascular system and did not transport water through the plant.

• The first plants had a very basic vascular system with a simple method of internal transport.

• The first plants had only long, needle-like leaves, from which water could evaporate easily.

• The first plants did not develop a vascular system and transported water through the plant by diffusion from cell to cell.

You find a green leafy moss growing in the forest. It is unquestionably:

• an angiosperm.

• a gymnosperm.

• a bryophyte.

• diploid.

• polyploid.

Plants with the diploid stage smaller than and dependent upon the haploid stage are called:

• bryophytes.

• ferns.

• gymnosperms.

• angiosperms.

• algae.

Both mosses and ferns must have freestanding water present (water droplets, for example) in order to fulfill their requirements for fertilization. Which statement is the best explanation for why this is true?

• Both mosses and ferns have male gametes that float in water to the female structure.

• Both mosses and ferns have gametes that require the plant to take in a lot of water in order to fulfill their photosynthetic requirements.

• Both mosses and ferns have motile female gametes that require water to travel to the male gametes.

• Both mosses and ferns have motile male and motile female gametes that come together in water to fertilize.

• Both mosses and ferns have motile male gametes that require water to travel to the female gametes.

Which statement is true about mosses and gymnosperms?

• Mosses are better adapted for desert habitats, whereas gymnosperms are better adapted for wet habitats.

• Mosses rely on liquid water for fertilization, whereas gymnosperms do not need liquid water for fertilization.

• Mosses are primarily diploid in their adult form, whereas gymnosperms are primarily haploid.

• Mosses produce flowers in order to reproduce, whereas gymnosperms produce cones.

• Mosses use wind pollination, whereas gymnosperms use insects for pollination.

Early seed plants were pollinated by:

• bees.

• wind.

• butterflies.

• birds.

• still water.
