Biology Trivia Questions On Cells! Quiz

2.

The ____ surrounds the outside of an animal cell.

Telescope
Mitochondrion
Cell membrane
Cell wall

Correct Answer

A. Cell membrane

Explanation

The cell membrane is a protective layer that surrounds the outside of an animal cell. It acts as a barrier, controlling the movement of substances in and out of the cell. It is made up of a phospholipid bilayer with embedded proteins that provide structural support and perform various functions such as transport and cell signaling. Unlike plant cells, animal cells do not have a cell wall, making the cell membrane essential for maintaining cell shape and integrity.

3.

The ____ is the control center of the cell.

Mitochondria
Cell membrane
Nucleus
Pores

Correct Answer

A. Nucleus

Explanation

The nucleus is often referred to as the control center of the cell because it houses the cell's DNA, which contains the instructions for cellular function and reproduction. It directs all activities within the cell by regulating gene expression, which in turn controls the synthesis of proteins that determine the cell's structure and function. This central role makes the nucleus essential for growth, metabolism, and the coordination of cell activities.

Plant cells contain ____ which are spaces, or sacs, that hold liquids.

Vacuoles
Cytoplasm
Reticulum
Golgi bodies

Correct Answer

A. Vacuoles

Explanation

Plant cells contain vacuoles which are spaces, or sacs, that hold liquids. Vacuoles are membrane-bound organelles found in plant cells that store water, ions, nutrients, and waste materials. They play a crucial role in maintaining turgor pressure, regulating cell size, storing pigments, and providing structural support to the plant. The large central vacuole in plant cells also helps in maintaining the shape of the cell and can occupy a significant portion of the cell's volume. Thus, vacuoles are responsible for storing and regulating the various substances in plant cells.

5.

The ____ are long and fiber-like, which make it possible to move arms and legs.

Transpiration
Teeth
Muscle cells
Blood cells

Correct Answer

A. Muscle cells

Explanation

Muscle cells are long and fiber-like, enabling the movement of arms and legs. These cells contain proteins called actin and myosin, which interact to generate force and produce movement. The arrangement of these proteins in muscle cells allows for contraction and relaxation, which results in the movement of body parts.

One of the most powerful instruments to view cells is the ____. This device uses magnets to focus beams of electrons on the subject.

Brain
Controller
Transpiration
Electron microscope

Correct Answer

A. Electron microscope

Explanation

The correct answer is electron microscope. An electron microscope is a powerful instrument that uses magnets to focus beams of electrons on the subject. This allows for highly detailed and magnified views of cells and other small structures.

7.

A Plant cell has a ____ which is not found in animal cells.

Cell wall
Cell membrane
Golgi body
Cells

Correct Answer

A. Cell wall

Explanation

A plant cell has a cell wall, which is a rigid structure made up of cellulose that surrounds the cell membrane. This cell wall provides support and protection to the plant cell, helping it maintain its shape and preventing it from bursting under pressure. Animal cells, on the other hand, do not have a cell wall. Instead, they have a flexible cell membrane that controls the movement of substances in and out of the cell. The presence of a cell wall is a characteristic feature of plant cells that distinguishes them from animal cells.

The smallest organisms on Earth are ____.

Plant cells
Animal cells
Bacteria
Storage cells

Correct Answer

A. Bacteria

Explanation

Bacteria are the smallest organisms on Earth. They are single-celled microorganisms that can be found in various environments, including soil, water, and even inside the human body. Unlike plant and animal cells, which are larger and more complex, bacteria are simple in structure and lack a true nucleus. They play a crucial role in various ecological processes and can have both beneficial and harmful effects on other organisms.

9.

The ____ is a gelatinlike substance that contains many chemicals that the cell needs.

Mitochondrion
Chromosomes
Chloroplast
Cytoplasm

Correct Answer

A. Cytoplasm

Explanation

The cytoplasm is a gelatinlike substance that contains many chemicals that the cell needs. It is a semi-fluid medium that fills the cell and acts as a site for various cellular activities. It contains organelles such as mitochondria and chloroplasts, as well as other structures like ribosomes and the cytoskeleton. The cytoplasm is involved in processes such as protein synthesis, metabolism, and transport of molecules within the cell. It provides a supportive environment for the cell's organelles and allows for the movement of substances within the cell.

10.

The ____ captures energy from sunlight and uses it to convert carbon dioxide and water into food.

Chloroplast
Cytoplasm
Vacuole
Mitochondria

Correct Answer

A. Chloroplast

Explanation

The chloroplast is the correct answer because it is the organelle responsible for photosynthesis in plant cells. It contains chlorophyll, a pigment that captures energy from sunlight. During photosynthesis, the chloroplast uses this energy to convert carbon dioxide and water into glucose, which is the plant's food source. The cytoplasm is the fluid inside the cell where various cellular processes occur, but it does not directly capture energy from sunlight or convert carbon dioxide and water into food. The vacuole is responsible for storing water and other substances, while mitochondria are the organelles responsible for cellular respiration, not photosynthesis.

11.

____ contain DNA, a chemical that determines which traits an organism will have.

Mitochondria
Cell membrane
Chromosomes
Vacuole

Correct Answer

A. Chromosomes

Explanation

Chromosomes contain DNA, a chemical that determines which traits an organism will have. DNA is organized into structures called chromosomes, which are located in the nucleus of a cell. These chromosomes contain genes that provide instructions for the development and functioning of an organism. The DNA within chromosomes carries the genetic information that determines an organism's traits, such as eye color, height, and susceptibility to certain diseases. Therefore, chromosomes are responsible for passing on genetic information from one generation to the next.

Different types of tissues working together can form a structure called a(n) ____.

Root
Organ
Tissue
System

Correct Answer

A. Organ

Explanation

Different types of tissues working together can form a structure called an organ. Organs are composed of different tissues that work together to perform specific functions in the body. They have a higher level of organization than tissues and are essential for the overall functioning of the organism. Examples of organs include the heart, liver, and lungs.
