Viruses to Plants Review

Which three characteristics are used to classify prokaryotes?

• by size, where they live, and whether they need air

• whether they have cell walls, flagella or cilia, and nuclei

• how they reproduce, where they get food, and whether they have DNA

• by shape, how they move and how they get energy

During a lytic infection, the host cell

• is destroyed when it bursts

• is not taken over right away by the virus

• carries a prophage that stays part of the DNA for many generations

• produces offspring that are infected by the virus.

Bacteria and archaea differ in

• whether they have a nucleus

• the makeup of their cell walls

• size

• whether they have a cell wall

How are protists related to other eukaryotes?

• Today's protists and plants, fungi, and animals have an ancient common ancestor

• Protists evolved from bacteria while the other eukaryotes evolved from archaea

• Today's protists gave rise to plants, fungi, and animals

• Today's protists arose from ancient plants, fungi, and animals.

Which of the following is true of fungi?

• Like plants, they carry out photosynthesis

• Like some prokaryotes, they are autotrophic

• Like animals, they lack cell walls

• Like protists, they are eukaryotic

In a mycorrhizal relationship, what benefit does the plant get from the fungus?

• an energy source

• aid in seed dispersal

• products of photosynthesis

• aid in the absorption of water and minerals

Which of the following is true?

• Plants have adaptations that minimize light absorption.

• Plants require less water on sunny days.

• Most plants get the water they need from the soil.

• Plants take carbon dioxide from the atmosphere and do not use oxygen

The ancestors of land plants likely evolved from

• mosses that lived in the water

• an organism similar to green algae.

• a protist that lived on land

• prokaryotes that carried on photosynthesis

In plants, the diploid phase is known as

• the gametophyte

• alternation of generations

• the sporophyte

• N phase

The specialized leaves of a flower that do not produce gametophytes are the

• carpel and stamens

• filaments and anthers

• stigma and style.

• sepals and petals.
