The Semi-Permeable outer boundary of the cell made of lipid and protein
- A.
Cell Membrane
- B.
Guard Cells
- C.
Homeostasis
- D.
Diffusion
Correct Answer
A. Cell MembraneExplanation
The cell membrane is the correct answer because it is a semi-permeable outer boundary of the cell that is composed of lipids and proteins. It controls the movement of substances in and out of the cell, allowing some to pass through while blocking others. The lipid bilayer of the cell membrane provides a barrier to hydrophilic molecules, while the proteins embedded in the membrane play a role in transport, signaling, and cell recognition. Overall, the cell membrane is crucial for maintaining the integrity and functionality of the cell.Rate this question:

Respiration that does not use molecular oxygen. It produces only 2 ATP as one glucose molecule is partially oxidized
- A.
Active Transport
- B.
Cellular Respiration
- C.
Anaerobic Respiration
- D.
Homeostasis
Correct Answer
C. Anaerobic RespirationExplanation
Anaerobic respiration is the correct answer because it is a form of respiration that does not require molecular oxygen. This process occurs in the absence of oxygen and produces only 2 ATP molecules as one glucose molecule is only partially oxidized. Anaerobic respiration is a less efficient form of respiration compared to aerobic respiration, which occurs in the presence of oxygen and produces a larger amount of ATP.Rate this question:

A process that uses energy to transport materials from an area of low concentration to high concentration
- A.
Aerobic Respiration
- B.
Active Transport
- C.
Passive Transport
- D.
Diffusion
Correct Answer
B. Active TransportExplanation
Active transport is the correct answer because it is a process that uses energy to transport materials from an area of low concentration to high concentration. Unlike passive transport, which does not require energy and moves materials from high to low concentration, active transport requires the use of energy in the form of ATP to move substances against their concentration gradient. This process is essential for maintaining cellular homeostasis and allows cells to accumulate nutrients or remove waste materials from their surroundings.Rate this question:

The movement of molecules from an area of high concentration to low concentration without the use of energy.
- A.
Osmosis
- B.
Cellular Respiration
- C.
Active Transport
- D.
Diffusion
Correct Answer
D. DiffusionExplanation
Diffusion is the correct answer because it refers to the movement of molecules from an area of high concentration to low concentration without the use of energy. This process occurs naturally in order to achieve equilibrium and is responsible for the spreading out and mixing of substances. Osmosis, on the other hand, specifically refers to the movement of water molecules across a semi-permeable membrane. Cellular respiration and active transport involve the use of energy to transport molecules, making them incorrect options.Rate this question:

The maintenance of a stable internal environment
- A.
Osmosis
- B.
Anaerobic Respiration
- C.
Homeostasis
- D.
Guard Cells
Correct Answer
C. HomeostasisExplanation
Homeostasis refers to the ability of an organism to maintain a stable internal environment despite external changes. It involves various physiological processes that work together to regulate temperature, pH, fluid balance, and other factors within narrow limits. Osmosis is the movement of water across a semi-permeable membrane, anaerobic respiration is a type of cellular respiration that occurs without oxygen, and guard cells are specialized cells in plant leaves that control the opening and closing of stomata. While these processes are important in their own right, they do not directly relate to the maintenance of a stable internal environment like homeostasis does.Rate this question:

ATP - Adenosine Triphosphate
- A.
One of the principal chemical compounds that living things use to store energy
- B.
Process in which energy is released from food and converted into a form that the cell can use
- C.
The maintenance of a stable internal environment
- D.
The diffusion of water through a semi-permeable membrane
Correct Answer
A. One of the principal chemical compounds that living things use to store energyExplanation
ATP (Adenosine Triphosphate) is a principal chemical compound used by living organisms to store and transfer energy. It is commonly referred to as the "energy currency" of the cell because it provides the necessary energy for various cellular processes. ATP is formed during cellular respiration, a process in which energy is released from food and converted into a usable form. It plays a crucial role in powering metabolic reactions, muscle contractions, active transport, and other energy-requiring processes in the cell. Overall, ATP serves as an essential molecule for energy storage and transfer in living organisms.Rate this question:

Process in which energy is released from food and converted into a form that the cell can use
- A.
Photosynthesis
- B.
Guard Cells
- C.
Chloroplast
- D.
Cellular Respiration
Correct Answer
D. Cellular RespirationExplanation
Cellular respiration is the correct answer because it is the process by which energy is released from food and converted into a form that the cell can use. During cellular respiration, glucose is broken down in the presence of oxygen to produce ATP, which is the main energy source for cells. This process occurs in the mitochondria of the cell and is essential for the survival and functioning of all living organisms.Rate this question:

Guard Cells
- A.
A chlorophyll-containing organelle located in plants where photosynthesis occurs
- B.
The semi-permeable outer boundary of the cell made of lipid and protein
- C.
Specialized cells that are found on the lower epidermis of leaves. Contain Chloroplasts and control the opening of the stomates
- D.
The process by which green plants use light energy to convert inorganic molecules into organic sugar
Correct Answer
C. Specialized cells that are found on the lower epidermis of leaves. Contain Chloroplasts and control the opening of the stomatesExplanation
Guard cells are specialized cells that are found on the lower epidermis of leaves. They contain chloroplasts, which enable them to carry out photosynthesis. Additionally, guard cells control the opening and closing of stomates, which are tiny openings on the surface of leaves that allow for gas exchange. By regulating the opening of stomates, guard cells help to control the movement of gases, such as carbon dioxide and oxygen, in and out of the leaf.Rate this question:

Diffusion. The movement of molecules from an area of high concentration to low concentration without the use of energy
- A.
Passive Transport
- B.
Active Transport
- C.
Osmosis
- D.
Diffusion
Correct Answer
A. Passive TransportExplanation
Passive transport refers to the movement of molecules across a cell membrane without the expenditure of energy. In this process, molecules move from an area of high concentration to an area of low concentration, following the concentration gradient. Diffusion is a type of passive transport where molecules move freely through the cell membrane. Therefore, the given answer "Passive Transport" accurately describes the process of diffusion, as it involves the movement of molecules from an area of high concentration to low concentration without the use of energy.Rate this question:

- A.
Guard Cells
- B.
Cell Membrane
- C.
Chloroplast
- D.
Cellular Respiration
Correct Answer
C. ChloroplastExplanation
Chloroplasts are the organelles found in plants that contain chlorophyll and are responsible for photosynthesis. During photosynthesis, chloroplasts capture sunlight and convert it into chemical energy, which is used to produce glucose and oxygen. This process is essential for the plant's survival and provides energy for growth and development. Therefore, the correct answer is chloroplast.Rate this question:

The process by which green plants use light energy to convert inorganic molecules into organic sugar
- A.
Diffusion
- B.
Osmosis
- C.
Photosynthesis
- D.
Cell membrane
Correct Answer
C. pHotosynthesisExplanation
Photosynthesis is the correct answer because it is the process by which green plants use light energy to convert inorganic molecules, such as carbon dioxide and water, into organic sugar molecules, such as glucose. This process occurs in the chloroplasts of plant cells and is essential for the production of oxygen and the conversion of sunlight into chemical energy. Diffusion is the passive movement of molecules from an area of higher concentration to an area of lower concentration, osmosis is the movement of water molecules across a semipermeable membrane, and the cell membrane is the outer boundary of a cell that regulates the passage of substances in and out of the cell.Rate this question:
