Which organelle creates ATP energy for a cell?
- A.
Chloroplast
- B.
Mitochondria
- C.
Ribosome
- D.
Nucleus
Correct Answer
B. MitochondriaExplanation
The mitochondria is the organelle responsible for creating ATP energy for a cell. ATP is the main energy currency of the cell, and it is produced through a process called cellular respiration, which takes place in the mitochondria. This organelle is often referred to as the "powerhouse" of the cell because it generates the energy needed for various cellular activities. The chloroplast, on the other hand, is responsible for photosynthesis in plant cells, not ATP production. Ribosomes are involved in protein synthesis, and the nucleus contains the cell's genetic material.Rate this question:

What is the function of chloroplasts?
- A.
Makes sugar from sunlight
- B.
Creates energy for the cell
- C.
Holds the DNA
- D.
Is used for storage
Correct Answer
A. Makes sugar from sunlightExplanation
Chloroplasts are responsible for converting sunlight into energy through the process of photosynthesis. During photosynthesis, chloroplasts use sunlight, water, and carbon dioxide to produce glucose (sugar) and oxygen. This glucose serves as a source of energy for the cell and is used for various cellular processes. Therefore, the function of chloroplasts is to make sugar from sunlight.Rate this question:

Plant cells have one big____ used for storage, but animal cells have lots of small ones.
- A.
Nucleus
- B.
Mitochondria
- C.
Vacuole
- D.
Cytoplasm
Correct Answer
C. VacuoleExplanation
Plant cells have one big vacuole used for storage, but animal cells have lots of small ones. The vacuole in plant cells is a large membrane-bound organelle that stores water, nutrients, and waste products. It helps maintain the cell's shape and structure, and also plays a role in regulating turgor pressure. In contrast, animal cells have smaller vacuoles that are involved in various functions such as storing waste, maintaining pH balance, and regulating ion concentration. The presence of one big vacuole in plant cells and multiple small vacuoles in animal cells is a key difference between the two cell types.Rate this question:

What are most important parts of chromosomes?
- A.
DNA
- B.
Proteins
- C.
Lipids
- D.
carbohydrates
Correct Answer
A. DNAExplanation
The most important parts of chromosomes are DNA. DNA carries the genetic information that determines an organism's traits and characteristics. It contains the instructions for building and maintaining an organism. Proteins, lipids, and carbohydrates are important components of cells, but they are not the primary components of chromosomes. Chromosomes are made up of DNA molecules that are tightly coiled and packaged with proteins called histones.Rate this question:

Which description best fits the cell membrane?
- A.
Transparent
- B.
Rigid for support
- C.
Thick and waxy
- D.
Semi-permeable
Correct Answer
D. Semi-permeableExplanation
The cell membrane is described as semi-permeable because it selectively allows certain substances to pass through while restricting the passage of others. This characteristic is essential for maintaining the internal environment of the cell and regulating the movement of molecules in and out of the cell.Rate this question:

Which of the following organelles do animal cells have?
- A.
Chloroplasts
- B.
Cell wall
- C.
One large vacuole
- D.
Mitochondria
Correct Answer
D. MitochondriaExplanation
Animal cells have mitochondria. Mitochondria are membrane-bound organelles found in the cytoplasm of eukaryotic cells. They are responsible for producing energy in the form of ATP through cellular respiration. Animal cells require energy for various cellular processes, and mitochondria play a crucial role in meeting this energy demand. Unlike plant cells, animal cells do not have chloroplasts, cell walls, or one large vacuole.Rate this question:

What is the function of the nucleus?
- A.
Storage for nutrients
- B.
Control center for cell
- C.
Makes energy
- D.
Photosynthesizes
Correct Answer
B. Control center for cellExplanation
The nucleus is the control center for the cell. It contains the cell's genetic material, including DNA, which carries the instructions for the cell's activities. The nucleus regulates gene expression and controls the synthesis of proteins necessary for cell function. It also plays a role in cell division, as it is involved in the replication and distribution of DNA during mitosis and meiosis. Therefore, the nucleus is essential for the overall coordination and regulation of cellular processes, making it the control center of the cell.Rate this question:

What is the nutritious goo inside cells called?
- A.
Chloroplasts
- B.
Nucleus
- C.
Cytoplasm
- D.
Cellojello
Correct Answer
C. CytoplasmExplanation
Cytoplasm is the correct answer because it refers to the gel-like substance found inside cells. It contains various nutrients, proteins, and organelles that are essential for the cell's functioning. Chloroplasts are responsible for photosynthesis in plant cells, while the nucleus is the control center of the cell. Cellojello is not a scientific term and does not exist.Rate this question:

Where does photosynthesis happen?
- A.
Chloroplasts
- B.
Ribosomes
- C.
Mitochondria
- D.
Vacuoles
Correct Answer
A. ChloroplastsExplanation
Photosynthesis is the process by which plants convert sunlight into energy. It occurs in the chloroplasts of plant cells, where chlorophyll, a green pigment, captures sunlight and uses it to convert carbon dioxide and water into glucose and oxygen. Chloroplasts are specialized organelles found in plant cells that contain chlorophyll and are responsible for carrying out photosynthesis. Therefore, the correct answer is chloroplasts.Rate this question:

Where are proteins made?
- A.
Chloroplasts
- B.
Mitochondria
- C.

- D.
Ribosomes
Correct Answer
D. RibosomesExplanation
Proteins are made in ribosomes. Ribosomes are small structures found in cells that are responsible for protein synthesis. They read the genetic information stored in DNA and use it to assemble amino acids into proteins. Therefore, ribosomes are the correct answer for where proteins are made.Rate this question:

Animal cells do not have...
- A.
Chloroplasts
- B.
Cell walls
- C.
A squarish shape
- D.
A large central vacuole
- E.
They have none of the above
Correct Answer
E. They have none of the aboveExplanation
Animal cells do not have chloroplasts, cell walls, a squarish shape, or a large central vacuole. These features are typically found in plant cells. Animal cells lack chloroplasts because they do not perform photosynthesis like plants do. They also lack cell walls, which provide structural support and protection in plant cells. Animal cells have a round or irregular shape, rather than a squarish shape. Additionally, animal cells do not have a large central vacuole, which is a storage organelle found in plant cells. Therefore, the correct answer is that animal cells have none of the above features.Rate this question:

Correct Answer
D. MitochondriaExplanation
The correct answer is mitochondria. Mitochondria are organelles found in eukaryotic cells that are responsible for generating energy in the form of ATP through cellular respiration. They have a double membrane structure and contain their own DNA, allowing them to produce some of their own proteins. Mitochondria are commonly referred to as the "powerhouses" of the cell due to their crucial role in energy production.Rate this question:

Correct Answer
C. ChloroplastExplanation
Chloroplasts are organelles found in plant cells that are responsible for photosynthesis. They contain chlorophyll, a pigment that captures sunlight and converts it into chemical energy. This energy is then used to produce glucose, which is the main source of energy for the plant. Chloroplasts also help in the synthesis of other important molecules, such as amino acids and lipids. Unlike other organelles listed, chloroplasts are only found in plant cells and are crucial for their survival and growth.Rate this question:
