Which term best describes the way cells work inside your body?
- A.
Corporation
- B.
Coagulation
- C.
Competition
- D.
Cooperation
Correct Answer
D. CooperationExplanation
Cooperation is the best term to describe the way cells work inside the body. Cells in the body work together in a coordinated manner to carry out various functions and maintain the overall health and functioning of the body. They communicate, interact, and support each other to perform their specific roles and contribute to the overall well-being of the organism. This cooperative behavior ensures the proper functioning and survival of the body as a whole.Rate this question:

What is the major difference between prokaryotic and eukaryotic cells?
- A.
Prokaryotic cells have no gentic material; eukaryotic cells do
- B.
Prokaryotic cells engage in photosntheisis; eukaryotic cells don't
- C.
Prokaryotic cells have no membranes around their nuclear material; enkaryotic cells do
- D.
Prokaryotic cells can move on their own; eukaryotic cells can't
Correct Answer
C. Prokaryotic cells have no membranes around their nuclear material; enkaryotic cells doExplanation
The major difference between prokaryotic and eukaryotic cells is that prokaryotic cells lack membranes around their nuclear material, while eukaryotic cells have these membranes. This difference is significant because the presence of nuclear membranes in eukaryotic cells allows for compartmentalization and organization of genetic material, which is essential for regulating gene expression and carrying out complex cellular processes. In contrast, prokaryotic cells have their genetic material floating freely in the cytoplasm, which limits their ability to regulate gene expression and perform specialized functions.Rate this question:

What is a major difference between plant and animal cells?
- A.
Plant cells are always at least 10 times bigger than animal cells
- B.
Plant cells are always green, while animal cells are always red
- C.
Plant cells are surrounded by cell walls; animal cells aren't
- D.
Plant cells are made of wood; animal cells are made of flesh
Correct Answer
C. Plant cells are surrounded by cell walls; animal cells aren'tExplanation
Plant cells are surrounded by cell walls, which provide structural support and protection for the cell. Animal cells, on the other hand, do not have cell walls and rely on other structures such as the cell membrane for support and protection. This key difference is due to the presence or absence of a cell wall, making it a major distinction between plant and animal cells.Rate this question:

What can you find inside a eukaryotic cell's nucleus?
- A.
Genetic material
- B.
Cytoplasm
- C.
Endoplasmic reticulum
- D.
Mitochondira
Correct Answer
A. Genetic materialExplanation
The correct answer is genetic material. The nucleus of a eukaryotic cell contains the genetic material, which is DNA. This DNA carries the instructions for the cell's functions and is responsible for determining the characteristics and traits of an organism. The genetic material is organized into structures called chromosomes, which are found inside the nucleus. The other options listed, cytoplasm, endoplasmic reticulum, and mitochondria, are not typically found inside the nucleus but are located in other parts of the cell.Rate this question:

Prokaryotic cells are all:
- A.
Single-celled organisms
- B.
Multi-celled organisms
- C.
Photosynthetic organisms
- D.
Large organisms
Correct Answer
A. Single-celled organismsExplanation
Prokaryotic cells are single-celled organisms because they lack a nucleus and other membrane-bound organelles. They are typically smaller and simpler in structure compared to eukaryotic cells. Prokaryotes, such as bacteria and archaea, are capable of carrying out all necessary functions for survival within a single cell. They reproduce through binary fission, where one cell divides into two identical daughter cells. Therefore, the correct answer is single-celled organisms.Rate this question:

Which of these statements is true of plant cells?
- A.
They have no cell membranes
- B.
They can make their own nutrients
- C.
They work independently of one another
- D.
They are prokaryotic
Correct Answer
B. They can make their own nutrientsExplanation
Plant cells have the ability to produce their own nutrients through the process of photosynthesis. This is a unique characteristic of plant cells, as they contain specialized structures called chloroplasts that contain chlorophyll, which enables them to convert sunlight, water, and carbon dioxide into glucose and oxygen. This process allows plants to synthesize their own food and sustain themselves without relying on external sources for nutrients.Rate this question:

What would happen is a plant cell didn'thave chloroplasts?
- A.
It wouldn't be able to reproduce
- B.
It woundn't be able to move
- C.
It wouldn't be able to make its own nutrients
- D.
It wouldn't be able to transport nutrients
Correct Answer
C. It wouldn't be able to make its own nutrientsExplanation
If a plant cell didn't have chloroplasts, it wouldn't be able to make its own nutrients through photosynthesis. Chloroplasts are responsible for capturing sunlight and converting it into energy through the process of photosynthesis. Without chloroplasts, the plant cell wouldn't be able to produce glucose and other organic molecules that it needs for growth and survival. Instead, it would have to rely on obtaining nutrients from its surroundings, which may not be sufficient for its needs.Rate this question:

What is a membrane?
- A.
Another term for a cell's nucleus
- B.
A sort of "skin" that encloses something
- C.
A type of genetic material
- D.
A single-celled organism
Correct Answer
B. A sort of "skin" that encloses somethingExplanation
A membrane is a sort of "skin" that encloses something. In biology, a membrane refers to a thin layer of tissue or material that acts as a boundary or barrier, separating the inside of a cell or an organ from its external environment. It controls the movement of substances in and out of the cell or organ, allowing for selective transport of molecules and maintaining the internal environment necessary for proper functioning.Rate this question:

Why do red blood cells need to be so tiny?
- A.
So they can move through narrow blood narrow blood vessels
- B.
So they can clump together
- C.
So they can't be detected by viruses
- D.
So they can carry carbon dioxide to our body's tissues
Correct Answer
A. So they can move through narrow blood narrow blood vesselsExplanation
Red blood cells need to be tiny in order to move through narrow blood vessels. Larger cells would not be able to navigate through the small capillaries and deliver oxygen to the body's tissues efficiently. The small size of red blood cells allows them to flow smoothly through the blood vessels, ensuring proper circulation and oxygenation throughout the body.Rate this question:
