1.
Where could you find members of the Kingdom Monera that are autotrophs?
Correct Answer
B. Near cracks in the ocean floor
Explanation
Autotrophs are organisms that can produce their own food using sunlight or inorganic substances, such as bacteria. The Kingdom Monera includes bacteria, which can be found near cracks in the ocean floor. These cracks, also known as hydrothermal vents, release hot, mineral-rich water into the ocean. The bacteria in this environment can perform chemosynthesis, using the minerals and chemicals from the vents to produce their own food. Therefore, the correct answer is near cracks in the ocean floor.
2.
Which of these monerans are NOT autotrophs?
Correct Answer
C. Nitrogen-fixing bacteria
Explanation
Nitrogen-fixing bacteria are not autotrophs because they cannot produce their own food through photosynthesis or chemosynthesis. Instead, they obtain their energy by converting atmospheric nitrogen into a usable form for other organisms. Autotrophs, such as cyanobacteria and some archaebacteria, can produce their own food using sunlight or inorganic compounds.
3.
Which of the following is NOT a disease caused by harmful bacteria?
Correct Answer
B. Erythromycin
Explanation
Erythromycin is not a disease caused by harmful bacteria, but rather a type of antibiotic medication used to treat bacterial infections. Botulism is caused by the bacterium Clostridium botulinum, tetanus is caused by the bacterium Clostridium tetani, and Lyme disease is caused by the bacterium Borrelia burgdorferi.
4.
The only kingdom of organisms to include____________is the Kingdom Monera.
Correct Answer
prokaryotes
Explanation
The correct answer is "prokaryotes". The question is asking for the only kingdom of organisms that includes a specific characteristic, which is not stated in the question. However, based on the answer "prokaryotes", we can infer that the characteristic being referred to is the absence of a nucleus in their cells. Prokaryotes are single-celled organisms that lack a membrane-bound nucleus, and they are classified in the Kingdom Monera.
5.
Which of the following characteristics is true for all members of Kingdom Monera?
Correct Answer
C. They reproduce through binary fission.
Explanation
Members of Kingdom Monera, which includes bacteria and cyanobacteria (blue-green algae), are characterized by their simple cellular structure. They are unicellular and lack a well-defined nucleus and membrane-bound organelles, making them prokaryotes. They reproduce asexually through a process called binary fission, where the cell divides into two identical daughter cells. Options A, B, and D describe characteristics of eukaryotic cells, not prokaryotic cells found in Kingdom Monera.
6.
Which kingdom?
Correct Answer
A. Monera
Explanation
The correct answer is monera. Monera is a kingdom that includes single-celled organisms such as bacteria. It is characterized by the absence of a nucleus and other membrane-bound organelles. Monera organisms are prokaryotic, meaning their genetic material is not enclosed within a nucleus. This kingdom also includes some forms of blue-green algae. Fungi and plantae are separate kingdoms that consist of multicellular organisms with distinct characteristics and structures.
7.
A heterotroph with a cell wall made of chitin would be in which kingdom?
Correct Answer
B. Fungi
Explanation
A heterotroph with a cell wall made of chitin would belong to the kingdom Fungi. This is because fungi are the only kingdom that have organisms with chitin cell walls. Chitin is a tough, flexible polysaccharide that provides structural support to the cell wall. Fungi are heterotrophic organisms that obtain nutrients by decomposing organic matter, and they play a vital role in the ecosystem as decomposers.
8.
Which of the following characteristics do all protista have in common?
Correct Answer
A. They are all eukaryotic
Explanation
All protista have in common the characteristic of being eukaryotic. This means that their cells have a true nucleus and other membrane-bound organelles. This distinguishes them from prokaryotes, which do not have a nucleus or membrane-bound organelles. The other characteristics listed, such as being unicellular or autotrophs, are not shared by all protista. Some protista are multicellular, and while many are autotrophs, there are also heterotrophic protista that obtain their nutrients from other organisms.
9.
Which of the following is NOT a characteristic of all plants?
Correct Answer
C. Contain vascular structures to transport materials
Explanation
Not all plants contain vascular structures. While most plants, like ferns, conifers, and flowering plants, have vascular tissues (xylem and phloem) to transport water, nutrients, and food, there are non-vascular plants, such as mosses and liverworts, that do not have these structures. However, all plants are multicellular and eukaryotic, which means they have cells with a nucleus and organelles.
10.
The cell walls of plant cells are made of:
Correct Answer
C. Cellulose
Explanation
The cell walls of plant cells are made of cellulose. Cellulose is a complex carbohydrate that provides structural support and rigidity to plant cells. It forms a network of fibers that make up the cell wall, giving it strength and allowing plants to maintain their shape. Cellulose is not found in animal cells, making it a unique characteristic of plant cells.
11.
Which of these is NOT a non-vascular plant?
Correct Answer
B. Fern
Explanation
Fern is the correct answer because it is a vascular plant, meaning it has specialized tissues for transporting water and nutrients. Non-vascular plants, on the other hand, do not have these specialized tissues and rely on other means, such as diffusion, to transport water and nutrients. Hornwort, moss, and liverwort are all examples of non-vascular plants.
12.
Ferns are vascular plants that reproduce by:
Correct Answer
A. Spores
Explanation
Ferns are vascular plants that reproduce by spores. Unlike flowering plants that reproduce through the production of flowers and seeds, ferns produce spores as their reproductive structures. Spores are small, single-celled structures that are released from the fern and can develop into new fern plants under favorable conditions. This method of reproduction allows ferns to colonize new areas and adapt to different environments. Cones are reproductive structures found in gymnosperms, while flowers are characteristic of angiosperms. Therefore, the correct answer is spores.
13.
Which of the following organisms do NOTbelong to phylum Chordata?
Correct Answer
B. Earthworm
Explanation
The earthworm does not belong to the phylum Chordata because it lacks a backbone or vertebral column, which is a defining characteristic of organisms in the phylum Chordata. The other three options, whale, lizard, and snake, all have a backbone and are classified as chordates.
