Flowering plants are called angiosperms. This term refers to a group of plants that produce flowers for sexual reproduction. Angiosperms are characterized by having enclosed seeds within a fruit, which aids in dispersal. They are the most diverse group of plants, with over 300,000 known species. Angiosperms play a crucial role in ecosystems as they provide food, shelter, and habitat for many organisms.
2.
What would be an example of an organism in the Plantae kingdom?
Correct Answer
D. Trees
Explanation
Trees would be an example of an organism in the Plantae kingdom because they are multicellular, photosynthetic organisms that have cell walls made of cellulose. They obtain energy through photosynthesis and reproduce through seeds or spores. Trees are classified as plants and belong to the Plantae kingdom along with other plants such as flowers, grasses, and ferns.
3.
What doesn't a plant need to survive?
Correct Answer
A. Food outside from the organism
Explanation
Plants do not need food from outside the organism to survive because they are capable of producing their own food through photosynthesis. They use sunlight, water, and minerals to carry out this process and convert them into glucose, which serves as their source of energy. Therefore, plants do not rely on external sources of food like animals do.
4.
What vascular tissue inside a plant carries water from the roots to other parts of the plant?
Correct Answer
C. Xylem
Explanation
Xylem is the correct answer because it is the vascular tissue responsible for transporting water and minerals from the roots to the rest of the plant. It consists of specialized cells called tracheids and vessel elements, which are arranged in a tube-like structure. Xylem plays a crucial role in maintaining the plant's water balance and providing support to the plant. Phloem, on the other hand, transports sugars and other organic compounds from the leaves to other parts of the plant. Spores and lignin are not vascular tissues and do not play a role in water transport.
5.
Where doesn't Eubacteria live?

10.
If a bacteria has a whiplike form of movement, what does it move with?
Correct Answer
B. Flagella
Explanation
Flagella are long, whip-like structures that bacteria use for movement. They are typically found in single or multiple numbers and help the bacteria to propel themselves through their environment. Cilia, on the other hand, are shorter and more numerous hair-like structures found on the surface of some cells, including certain types of bacteria. Slime and legs are not typically involved in bacterial movement. Therefore, the correct answer is flagella.
11.
makes food themselves.
Correct Answer
Autotrophs
Explanation
Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis. They do not rely on consuming other organisms for energy, but instead use sunlight or inorganic compounds to convert energy into usable forms. This ability to make food themselves distinguishes autotrophs from heterotrophs, which rely on consuming other organisms for energy.
12.
are eukaryotes that aren't a plant, animal, or fungus.
Correct Answer
Protists
Explanation
Protists are a diverse group of eukaryotic microorganisms that do not fit into the categories of plants, animals, or fungi. They are typically single-celled organisms, but some can form colonies. Protists can be found in various habitats, including freshwater, saltwater, and soil. They play important roles in ecosystems as producers, consumers, and decomposers. Some examples of protists include amoebas, algae, and protozoans.
13.
The prefix fits protists because they were the first eukaryotes on Earth.
Correct Answer
pro
Explanation
The prefix "pro" fits protists because it means "before" or "first" and protists were indeed the first eukaryotes on Earth. The term "protist" refers to a diverse group of eukaryotic microorganisms that do not fit into any other kingdom. They are believed to have originated billions of years ago and played a crucial role in the evolution of complex life forms. Therefore, the prefix "pro" accurately describes the status of protists as the first eukaryotes.
14.
is a protist that is a disease that comes from mosquitos.
Correct Answer
Malaria
Explanation
Malaria is a disease caused by a protist that is transmitted through the bite of infected mosquitoes. The protist, called Plasmodium, infects the red blood cells and causes symptoms such as fever, chills, and flu-like illness. Malaria is a major global health problem, particularly in tropical and subtropical regions where mosquitoes thrive. It can be a life-threatening condition if not promptly diagnosed and treated. Various preventive measures, such as insecticide-treated bed nets and antimalarial medications, are used to control the spread of malaria.
15.
Protists can be animal-like , plant-like autotrophs, or fungus-like decomposers.
Correct Answer
Heterotrophs
Explanation
Protists can be animal-like heterotrophs, meaning they obtain their energy by consuming other organisms. They can also be plant-like autotrophs, which means they can produce their own food through photosynthesis. Additionally, protists can be fungus-like decomposers, meaning they obtain their nutrients by breaking down dead organic matter.
16.
Organisms in the kingdom have no cell wall, are heterotrophs, and eukaryotic.
Correct Answer
Animalia

Organisms in the Animalia kingdom have no cell wall, are heterotrophs, and eukaryotic. Animal cells do not have a rigid cell wall like plant cells, allowing them to have more flexibility in movement. They are heterotrophs, meaning they obtain their energy by consuming other organisms. Lastly, animal cells are eukaryotic, which means they have a true nucleus and other membrane-bound organelles within their cells. Therefore, the correct answer is Animalia.
17.
Humans are a member of the kingdom .
Correct Answer
Animalia
Explanation
Humans are classified as members of the kingdom Animalia because they share common characteristics with other animals. Animalia is a kingdom that includes multicellular organisms that are heterotrophic, meaning they obtain their nutrients by consuming other organisms. Humans, like other animals, are multicellular and obtain their nutrients by consuming plants and other animals. They also have specialized organ systems, such as a digestive system and a circulatory system, which are common features of animals. Therefore, humans are classified as members of the kingdom Animalia.
18.
The three are Bacteria, Archaea, and Eukarya.
Correct Answer
Domains
Explanation
The three domains are Bacteria, Archaea, and Eukarya. These domains represent the highest level of classification for all living organisms. Bacteria and Archaea are prokaryotic organisms, which means they lack a nucleus and other membrane-bound organelles. Eukarya, on the other hand, includes all eukaryotic organisms, which have a nucleus and other membrane-bound organelles. This classification system helps scientists understand the evolutionary relationships and diversity among different organisms.
19.
In the Domain Eukarya, all the organisms have a .
Correct Answer
Nucleus
Explanation
In the Domain Eukarya, all organisms have a nucleus. The nucleus is a membrane-bound organelle that contains the genetic material of the cell, including DNA. It is responsible for controlling the activities of the cell and is essential for cell division and reproduction. The presence of a nucleus is one of the defining characteristics of eukaryotic organisms, which include plants, animals, fungi, and protists. The nucleus allows for more complex cellular processes and enables eukaryotes to have specialized cell types and perform more diverse functions compared to prokaryotic organisms.

Explanation
Yeast is the only unicellular fungi.
21.
The above-ground part of fungi is called the fruiting-body.
Correct Answer
A. True
Explanation
Fungi have a unique life cycle that involves the production of a reproductive structure called the fruiting body. This structure is responsible for producing and dispersing spores, which are necessary for the fungi to reproduce. The fruiting body is the visible part of the fungus that is typically found above the ground, such as mushrooms or toadstools. Therefore, it is correct to say that the above-ground part of fungi is called the fruiting body.
22.
When fungi reproduces asexually, the stolon breaks off and produces spores.
Correct Answer
B. False
Explanation
When fungi reproduces asexually, it typically does not involve the breaking off of stolons to produce spores. Instead, asexual reproduction in fungi occurs through processes such as budding or fragmentation, where a portion of the parent organism develops into a new individual. Spores are usually produced during sexual reproduction in fungi. Therefore, the statement is incorrect.
23.
