Looking Inside Cells! Trivia Quiz

1.

The rigid layer of nonliving material that surrounds the cells of plants is called_______

A.

Cell wall
B.

Cell membrane
C.

Cytoplasm
D.

Plasmadesmata

Correct Answer
A. Cell wall

Explanation
The correct answer is cell wall. The cell wall is a rigid layer of nonliving material that surrounds the cells of plants. It provides structural support and protection to the plant cells, helping them maintain their shape and preventing them from bursting under pressure. The cell wall is made up of cellulose, a complex carbohydrate that gives it its strength and rigidity. Unlike the cell membrane, which is a selectively permeable barrier, the cell wall is permeable to water and other substances, allowing for the exchange of materials between cells. Plasmadesmata are small channels that connect plant cells, allowing for communication and transport of materials between them. Cytoplasm is the jelly-like substance that fills the cell and contains various organelles.

2.

______ are tiny cell structures that carry out specific functions within the cell.

A.

Organelles
B.

Centrosomes
C.

Chromatin
D.

Ribosomes

Correct Answer
A. Organelles

Explanation
Organelles are tiny cell structures that carry out specific functions within the cell. They are like tiny organs within the cell that perform various tasks such as producing energy, synthesizing proteins, storing materials, and facilitating cell division. Examples of organelles include mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. Each organelle has a specific function and contributes to the overall functioning and survival of the cell. Therefore, organelles are the correct answer to the question.

The ________________________ is a large, oval structure that directs all of the cell’s activities.

A.

Nucleus
B.

Nucleolus
C.

Mitochondria
D.

Endoplasmic reticulum

Correct Answer
A. Nucleus

Explanation
The nucleus is a large, oval structure that directs all of the cell's activities. It contains the cell's genetic material, including DNA, and controls the cell's functions such as growth, reproduction, and metabolism. The nucleus is surrounded by a nuclear membrane, which helps protect and regulate the movement of molecules in and out of the nucleus. It also contains a nucleolus, which is involved in the production of ribosomes. The other options, such as nucleolus, mitochondria, and endoplasmic reticulum, are all important organelles in the cell, but they do not direct all of the cell's activities like the nucleus does.

4.

_________ helps the nucleus to “know” how to direct the cell. It looks like thin strands floating directly around in the nucleus.

A.

Chromatin
B.

Chloroplasts
C.

Centrosomes
D.

Chlorophyll

Correct Answer
A. Chromatin

Explanation
Chromatin helps the nucleus to "know" how to direct the cell. It looks like thin strands floating directly around in the nucleus. Chromatin is made up of DNA and proteins, and it plays a crucial role in regulating gene expression and organizing the genetic material within the nucleus. It helps control which genes are turned on or off, allowing the cell to carry out specific functions and respond to its environment.

What is found in the area between the cell membrane and the nucleus?

A.

Cytoplasm
B.

Chromatin
C.

Centrosomes
D.

Endoplasmic reticulum

Correct Answer
A. Cytoplasm

Explanation
The cytoplasm is found in the area between the cell membrane and the nucleus. It is a gel-like substance that fills the cell and contains various organelles, such as the endoplasmic reticulum and centrosomes. The cytoplasm is responsible for supporting and protecting the organelles within the cell, as well as facilitating the movement of molecules and organelles throughout the cell. Chromatin, on the other hand, refers to the material that makes up the chromosomes within the nucleus.

This structure receives proteins and other newly formed transported materials, packages them, and distributes them to other parts of the cell.

A.

Golgi bodies (apparatus)
B.

Endoplasmic reticulum
C.

Ribosomes
D.

Centrosomes

Correct Answer
A. Golgi bodies (apparatus)

Explanation
The Golgi bodies (apparatus) are responsible for receiving proteins and other newly formed transported materials from the endoplasmic reticulum. They then package these materials and distribute them to other parts of the cell. The Golgi bodies play a crucial role in the intracellular transport and sorting of proteins, ensuring that they are delivered to the correct destinations within the cell. The other options, such as the endoplasmic reticulum, ribosomes, and centrosomes, do not perform these specific functions of receiving, packaging, and distributing proteins.

A structure in the cells of plants that captures energy from sunlight and uses it to produce food.

A.

Chloroplasts
B.

Chromatin
C.

Golgi Bodies
D.

Peroxisomes

Correct Answer
A. Chloroplasts

Explanation
Chloroplasts are the correct answer because they are the structures in plant cells that capture energy from sunlight through the process of photosynthesis. This captured energy is then used to produce food for the plant in the form of glucose. Chloroplasts contain the pigment chlorophyll, which gives them their green color and allows them to absorb sunlight. Through photosynthesis, chloroplasts convert carbon dioxide and water into glucose and oxygen, providing energy for the plant's growth and development.

––––––––– is a pouch inside a cell that acts as a storage area.

A.

Vacuole
B.

Mitochondria
C.

Chloroplast
D.

Peroxisome

Correct Answer
A. Vacuole

Explanation
A vacuole is a pouch inside a cell that acts as a storage area. It is responsible for storing various substances such as water, nutrients, and waste products. Vacuoles are found in both plant and animal cells, but they are larger and more prominent in plant cells. They play a crucial role in maintaining the cell's shape and turgor pressure, as well as regulating the cell's internal environment. Additionally, vacuoles can also contain pigments and toxins in some specialized cells.

What is a lysosome?

A.

A lysosome is a small, round structure containing chemicals that break down certain materials, in the cell. Some chemicals break down large food particles into smaller ones. Lysosomes also break down old cell parts and release the substances so they can be used again.
B.

A lysosome is a storage area in the cell.
C.

Lysosomes receive proteins and other newly formed materials from the endoplasmic reticulum.
D.

Lysosomes are the region between the cell membrane and the nucleus.

Correct Answer
A. A lysosome is a small, round structure containing chemicals that break down certain materials, in the cell. Some chemicals break down large food particles into smaller ones. Lysosomes also break down old cell parts and release the substances so they can be used again.

Explanation
A lysosome is a small, round structure in the cell that contains chemicals responsible for breaking down certain materials. These chemicals help break down large food particles into smaller ones, as well as break down old cell parts and release the substances so they can be used again. This process of breaking down and recycling materials is essential for maintaining the cell's overall function and health.

An organelle found in a plant cell and not in an animal cell is______________________.

A.

An organelle found in a plant cell and not in an animal cell is a cell wall.
B.

An organelle found in a plant cell and not in an animal cell is a nucleus.
C.

An organelle found in a plant cell and not in an animal cell is a vacuole.
D.

An organelle found in a plant cell and not in an animal cell is bacteria.

Correct Answer
A. An organelle found in a plant cell and not in an animal cell is a cell wall.

Explanation
The cell wall is a rigid structure that surrounds the cell membrane in plant cells. It provides support and protection to the cell, which is necessary for the plant's upright growth. Animal cells do not have a cell wall, as they have a flexible cell membrane that allows for movement and shape changes. Therefore, the cell wall is a unique organelle found only in plant cells and not in animal cells.
