| A | B |
|---|
| What type of cells have an organized nucleus and specialized organelles? | eukaryotes (eukaryotic cells) |
| Which kingdoms contain organisms with eukaryotic cells? | Kingdom Animalia (animal kingdom), Kingdom Plantae (plant kingdom), Kingdom Fungi (fungi kingdom), and Kingdom Protista (protist kingdom) |
| What type of cells are very simple in structure, having no nucleus to hold their DNA? | prokarytes (prokaryotic cells) |
| Organisms, such as fungi and bacteria of decay, that breakdown organic matter and recycle the nutrients back into the air, soil, and water are collectively known as ___. | decomposers |
| A pathogen is any organism that causes ___. | disease |
| All members of this kingdom have the ability to move from place to place (locomote). | Kingdom Animalia (animal kingdom) |
| Unicellular members of these two kingdoms have the ability to locomote. | Kingdom Protista (protist kingdom) and Kingdom Monera (moneran kingdom) |
| Why are fungi and bacteria of decay important to an ecosystem? | They aid in the breakdown of dead organisms and help recycle nutrients released during the process of decay. |
| Which group of organisms has the following characteristics? (a) are unicellular animal-like protists (b) possess specialized structures, such as cilia and flagella, for locomotion (c) are heterotrophic (d) primarily reproduce asexually by binary fission | protozoans |
| Which kingdom has organisms that can live in extreme environments and are the most ancient of all bacteria. | Kingdom Archaebacteria |
| How do most fungi reproduce? | asexually by spores |
| How do animals reproduce? | sexually; most by union of sperm and egg |
| How do plants reproduce? | sexually; most by union of sperm and egg |
| What is the primary reproductive structure in plants? | the seed |
| How do most unicellular protists reproduce? | asexually by binary fission |
| How do bacteria reproduce? | asexually by binary fission |
| Animals that have a definite top and bottom, definite right and left side, and a definite back (dorsal) and front (ventral) surface have what type of symmetry? | bilaterial symmetry |
| Animals whose bodies are arranged around a central hub have what type of symmetry? | radial symmetry |
| How do viruses reproduce? | by injecting their DNA into a host cell, causing the host cell to produce new virus particles |
| Why are Euglena unique among protists? | They contain chlorophyll and can make their food by photosynthesis. They can swim from place to place like animals. |
| Which kingdom has organisms that are plantlike in appearance but lack true roots, stems, and leaves? | Kingdom Fungi (fungi kingdom) |
| The members of which kingdom have very complex ekaryotic cells, are multicellular, are heterotrophic, reproduce sexually, can locomote, and often contain complex tissues, organs, and organ systems? | Kingdom Animalia (animal kingdom) |
| The members of which kingdom are all autotrophic because they contain chlorophyll, are all composed of many complex eukaryotic cells, and reproduce sexually? | Kingdom Plantae (plant kingdom) |
| The members of which kingdom have eukaryotic cells and absorb their nutrients though hairlike filaments called hyphae? | Kingdom Fungi (fungi kingdom) |
| Many members of this kingdom have true leaves, stems, and roots and produce seeds that are protected by either a fruit or cone. | Kingdom Plantae (plant kingdom) |
| Members of this kingdom are primarily unicellular, but they prefer living in clusters or chainlike colonies. Their cells are prokaryotic in form. Though many cause disease, some are very beneficial to man. | Kingdoms Eubacteria and Archaebacteria (bacteria kingdoms) |
| All members of this kingdom are multicellular and ingest their food. | Kingdom Animalia (animal kingdom) |
| One member of this kingdom looks like a spinning ball. It is really a colony of unicellular organisms that contain several nuclei and chlorophyll. | Kingdom Protista (protist kingdom) |
| Members of this kingdom are filled with a variety of pigments, though in spring and summer, chlorophyll is the most noticeable. They are able to capture the sun's energy to synthesize food. Most contain bundles of vascular tissue for transporting water and the food made during photosynthesis. | Kingdom Plantae (plant kingdom) |
