1.
Fungi
Correct Answer
D. All of the above
Explanation
The correct answer is "all of the above" because fungi do not contain chloroplasts, which are responsible for photosynthesis in plants. Fungi also have cell walls that contain chitin, a substance not found in other organisms. Additionally, fungi do not produce their own food through photosynthesis, but instead obtain nutrients by decomposing organic matter or living as parasites. Therefore, all three statements are true and correctly describe characteristics of fungi.
2.
Fungi obtain energy
Correct Answer
C. By absorbing digested nutrients.
Explanation
Fungi obtain energy by absorbing digested nutrients. Unlike plants, fungi do not have the ability to perform photosynthesis and obtain energy directly from the sun. Instead, they obtain their nutrients by breaking down organic matter in their environment, such as dead plants or animals. This process is known as absorption, where the fungi secrete enzymes to break down complex organic compounds into simpler molecules that can be absorbed and used as a source of energy. Therefore, fungi obtain their energy by absorbing digested nutrients.
3.
All of the members of the kingdom Animalia
Correct Answer
D. All of the above
Explanation
All of the options listed are true statements about the members of the kingdom Animalia. They are heterotrophs, meaning they obtain their energy by consuming other organisms. They are multicellular, meaning they are made up of more than one cell. And they have cells without cell walls, which is a characteristic that distinguishes them from members of other kingdoms, such as Plantae or Fungi. Therefore, the correct answer is "All of the above."
4.
Which of the following is found only in animals?
Correct Answer
C. Muscle tissue and nervous tissue.
Explanation
Muscle tissue and nervous tissue are found only in animals. Muscle tissue is responsible for movement in animals, allowing them to perform various actions such as walking, flying, or swimming. Nervous tissue enables animals to process information from their environment and coordinate their movements. While other options like the ability to move, sexual reproduction, and heterotrophy are also common in animals, muscle tissue and nervous tissue are unique to them.
5.
Without gas exchange, a plant would be unable to
Correct Answer
A. Make food.
Explanation
Plants require gas exchange to perform photosynthesis, which is the process of converting sunlight, water, and carbon dioxide into glucose (food). Without gas exchange, plants would not be able to take in carbon dioxide and release oxygen, which is essential for photosynthesis. Therefore, the correct answer is "make food."
6.
A plant is a
Correct Answer
D. Multicellular eukaryote.
Explanation
The correct answer is multicellular eukaryote. A plant is a multicellular organism because it is composed of multiple cells that work together to perform various functions. Plants are also eukaryotes because their cells have a nucleus and other membrane-bound organelles.
7.
Eukaryotes usually contain
Correct Answer
D. All of the above.
Explanation
Eukaryotes are organisms that have a true nucleus and specialized organelles within their cells. The nucleus contains the genetic material, which is responsible for storing and transmitting the organism's genetic information. Therefore, the correct answer is "all of the above" because eukaryotes typically possess all these characteristics.
8.
Which characteristics do most animals share?
Correct Answer
D. All of the above
Explanation
Most animals share the characteristics of being able to move, having sensory organs, and having internal digestion. This means that they are capable of locomotion, have organs such as eyes and ears to perceive their environment, and have a digestive system to break down food internally. Therefore, the correct answer is "All of the above".
9.
Plants use the energy of sunlight to
Correct Answer
D. Carry out pHotosynthesis.
Explanation
Plants use the energy of sunlight to carry out photosynthesis. During photosynthesis, plants convert sunlight, water, and carbon dioxide into glucose (a form of sugar) and oxygen. This process allows plants to produce their own food and release oxygen into the atmosphere. Therefore, the correct answer is "carry out photosynthesis."
10.
This is a type of organism that is a multicellular photosynthetic autotroph with cell walls made of cellulose.
Correct Answer
A. Plant
Explanation
The correct answer is plant because plants are multicellular photosynthetic autotrophs that have cell walls made of cellulose. They are capable of producing their own food through the process of photosynthesis and play a crucial role in the ecosystem by converting sunlight into energy and releasing oxygen as a byproduct.
11.
This is any organism that breaks down and obtains energy from dead organic matter.
Correct Answer
D. Decomposer
Explanation
A decomposer is an organism that breaks down and obtains energy from dead organic matter. Decomposers play a crucial role in the ecosystem by breaking down organic material, such as dead plants and animals, and recycling nutrients back into the environment. They help to decompose organic waste and facilitate the recycling of nutrients, making them available for other organisms to use. Examples of decomposers include bacteria, fungi, and certain types of insects.
12.
Fungi are
Correct Answer
D. Decomposers & heterotropHs
Explanation
Fungi are decomposers because they obtain their nutrients by breaking down organic matter. They secrete enzymes that break down complex organic compounds into simpler forms, which they can then absorb and use for energy. Fungi are also heterotrophs because they cannot produce their own food through photosynthesis and rely on external sources for nutrition. Therefore, the correct answer is "decomposers & heterotrophs."
13.
An organism that is ____ has the ability to move independently.
Correct Answer
A. Motile
Explanation
Motile refers to the ability of an organism to move independently. This means that the organism is capable of changing its location or position on its own. It can actively move from one place to another, whether it is through crawling, swimming, flying, or any other means of locomotion. Therefore, an organism that is motile has the ability to move independently.
14.
Which one contains some organisms that are NOT multicellular?
Correct Answer
C. Fungi
Explanation
Fungi is the correct answer because while plants and animals are multicellular organisms, fungi includes both multicellular and unicellular organisms. Some fungi, such as yeast, are unicellular, while others, like mushrooms, are multicellular. Therefore, fungi contains some organisms that are not multicellular.
