1.
The 3 scientists most responsible for the development of Cell Theory are:
Correct Answer
B. Theodor Schwann, Matthias Schleiden, and Rudolf Virchow
Explanation
The correct answer is Theodor Schwann, Matthias Schleiden, and Rudolf Virchow. These three scientists are considered the most responsible for the development of Cell Theory. Schwann and Schleiden proposed that all living organisms are composed of cells, while Virchow added the concept that cells only arise from pre-existing cells. Their combined contributions laid the foundation for our understanding of cells and their role in living organisms.
2.
All living things share 6 common characteristics. This means that
Correct Answer
D. All living things exhibit all 6 characteristics, or they are not considered living things.
Explanation
All living things exhibit all 6 characteristics, or they are not considered living things. This means that for something to be classified as a living thing, it must possess all of the 6 common characteristics shared by all living things. If an organism lacks even one of these characteristics, it cannot be considered a living thing. This answer implies that the presence of these characteristics is essential for defining something as living.
3.
What do we mean by "cellular organization"?
Correct Answer
B. Cells are the basic building blocks of all living things because all living things are composed of cells.
Explanation
The correct answer is "Cells are the basic building blocks of all living things because all living things are composed of cells." This answer explains that cellular organization refers to the fact that all living things are made up of cells, which are the fundamental units of life. This concept is a key principle of the Cell Theory, which states that cells are the basic structural and functional units of all living organisms. Therefore, understanding cellular organization is essential in understanding how living things are structured and function.
4.
Check all that are true about multicellular organisms.
Correct Answer(s)
A. They are composed of more than one cell.
C. They usually have cells that are organized into tissue, organs, and organ systems.
E. Cells in multicellular organisms may perform very different functions.
Explanation
Multicellular organisms are composed of more than one cell, which means they are made up of multiple cells working together. They usually have cells that are organized into tissues, organs, and organ systems, which allows for specialized functions and efficient functioning of the organism. Additionally, cells in multicellular organisms may perform very different functions, as different cells specialize in different tasks to support the overall functioning of the organism.
5.
Some organisms are composed of only one cell.
Correct Answer
A. True
Explanation
Some organisms, known as unicellular organisms, are made up of only one cell. These organisms carry out all of their life processes within a single cell, including obtaining nutrients, reproducing, and responding to their environment. Examples of unicellular organisms include bacteria, protozoa, and some types of algae. Therefore, the statement "Some organisms are composed of only one cell" is true.
6.
Some organisms are composed of many cells.
Correct Answer
A. True
Explanation
Some organisms, such as plants and animals, are indeed composed of many cells. These organisms are known as multicellular organisms. Each cell in these organisms performs specific functions and works together with other cells to carry out various biological processes. This allows for greater complexity and specialization within the organism, enabling them to perform a wide range of tasks and functions.
7.
What is the most important chemical for life?
Correct Answer
A. Water
Explanation
Water is the most important chemical for life because it is essential for the survival and functioning of all living organisms. It is involved in numerous biological processes such as transportation of nutrients and waste, regulation of body temperature, and maintenance of cell structure. Water also acts as a solvent for various biochemical reactions and is a key component of many biological fluids, including blood and cytoplasm. Without water, life as we know it would not be possible.
8.
Water is the only chemical found in all living cells.
Correct Answer
B. False
Explanation
Water is not the only chemical found in all living cells. While water is a crucial component of cells and makes up a significant portion of their mass, there are many other chemicals present as well. Living cells also contain various organic and inorganic molecules such as proteins, lipids, carbohydrates, nucleic acids, and ions. These molecules play essential roles in cell structure, metabolism, and genetic information. Therefore, the statement that water is the only chemical found in all living cells is false.
9.
When we talk about an organisms ability to use energy to perform its daily functions, we are talking about the organism's
Correct Answer
B. Metabolism
Explanation
Metabolism refers to the chemical processes that occur within an organism to convert food into energy and perform various functions. It involves the breakdown of nutrients, such as carbohydrates and fats, to release energy and the synthesis of molecules needed for growth and repair. Therefore, when we talk about an organism's ability to use energy to perform its daily functions, we are referring to its metabolism. The other options, psyche and ability to reproduce, are not directly related to energy utilization and daily functions.
10.
Which of the following are part of the Cell Theory?
Correct Answer(s)
B. All organisms are made up of one or more cells.
C. The cell is the basic unit of structure and function of living things because all life functions occur within cells.
D. All cells come from pre-existing cells.
Explanation
The Cell Theory states that all organisms are made up of one or more cells, the cell is the basic unit of structure and function of living things because all life functions occur within cells, and all cells come from pre-existing cells. This means that cells are the building blocks of life and that new cells are formed through cell division. The statement "Cells are made primarily of water" is not part of the Cell Theory, although it is true that cells contain a high percentage of water.
