Cells And Tissues: Life Science Test Quiz! - Quiz

A Cell is the basic unit of life, whereas tissues are groups of cells with a similar structure and act together to perform a specific function. This quiz will evaluate the knowledge about Cells and tissue concepts related to plants, animals, and human organs. Read the questions carefully and answer.

Questions and Answers

1.

During cellular respiration, cells produce a waste product called
- A.
  
  Sugar
- B.
  
  Oxygen
- C.
  
  Carbon dioxide
- D.
  
  Nitrogen
Correct Answer
C. Carbon dioxide

Explanation
During cellular respiration, cells break down glucose (sugar) to produce energy. One of the byproducts of this process is carbon dioxide. Carbon dioxide is then transported out of the cells and into the bloodstream, where it is eventually exhaled from the body through the lungs. Therefore, carbon dioxide is the waste product produced during cellular respiration.

The plant organ in which photosynthesis usually takes place is the:
- A.
  
  Leaf.
- B.
  
  Chloroplast.
- C.
  
  Root.
- D.
  
  Flower.
Correct Answer
A. Leaf.

Explanation
Photosynthesis is the process by which plants convert sunlight into energy. The primary site for this process is the leaf, where specialized cells called chloroplasts contain chlorophyll, the pigment responsible for capturing light energy. Chloroplasts are found in abundance in leaf cells, allowing for efficient absorption of sunlight. While other plant organs may contain chloroplasts to a lesser extent, the leaf is the main site for photosynthesis due to its large surface area and exposure to sunlight.

The human heart contains three kinds of tissue. The heart is:
- A.
  
  A tissue.
- B.
  
  An organ
- C.
  
  An organ system.
- D.
  
  An organelle
Correct Answer
B. An organ

Explanation
The human heart is considered an organ because it is a complex structure made up of different types of tissues that work together to perform a specific function. It is responsible for pumping blood throughout the body, which is essential for delivering oxygen and nutrients to the cells and removing waste products. An organ system, on the other hand, is a group of organs that work together to perform a common function, such as the circulatory system which includes the heart, blood vessels, and blood. An organelle refers to a specialized structure within a cell, so it is not applicable to the human heart.

What is not the main type of animal tissue?
- A.
  
  Muscle
- B.
  
  Epithelial
- C.
  
  Connective
- D.
  
  Digestive
Correct Answer
D. Digestive

Explanation
The main types of animal tissue are muscle, epithelial, and connective tissue. Digestive tissue is not a main type of animal tissue. The main function of digestive tissue is to aid in the digestion and absorption of nutrients, while muscle tissue is responsible for movement, epithelial tissue covers and protects the body, and connective tissue supports and connects different parts of the body. Therefore, digestive tissue is not considered a main type of animal tissue.

Your stomach lining is composed of specialized cells within this tissue that help you digest your food.
- A.
  
  Nervous tissue
- B.
  
  Muscle tissue
- C.
  
  Connective tissue
- D.
  
  Epithelial tissue
Correct Answer
D. Epithelial tissue

Explanation
Epithelial tissue is the correct answer because it is the type of tissue that lines the stomach and other organs in the body. It is made up of specialized cells that are tightly packed together, forming a protective barrier. In the case of the stomach lining, the epithelial tissue helps in the digestion process by secreting enzymes and absorbing nutrients from the food.

6.

Blood is a special kind of this type of tissue.
- A.
  
  Muscle
- B.
  
  Connective
- C.
  
  Epithelial
- D.
  
  Nervous
Correct Answer
B. Connective

Explanation
Connective tissue is the correct answer because blood is classified as a type of connective tissue. Connective tissue is responsible for connecting and supporting different structures in the body. It consists of cells and an extracellular matrix that contains various fibers and ground substance. Blood is a connective tissue because it is composed of cells (red and white blood cells) suspended in a fluid matrix called plasma. It plays a crucial role in transporting oxygen, nutrients, hormones, and waste products throughout the body.

What is not an example of plant tissue?
- A.
  
  Photosynthetic
- B.
  
  Protective
- C.
  
  Transport
- D.
  
  Growth
Correct Answer
D. Growth

Explanation
Growth is not an example of plant tissue because growth is a process that occurs in all plant tissues, rather than being a specific type of tissue itself. Plant tissues include photosynthetic tissue (such as leaves), protective tissue (such as the epidermis), and transport tissue (such as xylem and phloem). Growth is a fundamental characteristic of plants and involves cell division and expansion, which occur in all tissues to some extent.

What is an organ system of plants?
- A.
  
  Root system
- B.
  
  Reproductive system
- C.
  
  Growth system
- D.
  
  Photosynthetic system
Correct Answer
A. Root system

Explanation
The root system is considered an organ system of plants because it consists of the roots, which are responsible for anchoring the plant in the ground, absorbing water and nutrients, and storing food. The root system plays a vital role in the overall growth and development of the plant, as it provides support and nourishment. Additionally, the root system interacts with other organ systems, such as the shoot system, to ensure the plant's survival and reproduction.

A leaf is an example of?
- A.
  
  A plant organ system.
- B.
  
  A plant cell.
- C.
  
  A plant tissue.
- D.
  
  A plant organ.
Correct Answer
D. A plant organ.

Explanation
A leaf is considered a plant organ because it is a distinct and specialized structure within a plant that performs specific functions. It is composed of different tissues, such as the epidermis, mesophyll, and veins, which work together to carry out photosynthesis, transpiration, and gas exchange. As an organ, the leaf is part of the overall organization of a plant's body and plays a crucial role in its growth, development, and survival.

The heart is lined with a tissue called the epicardium, which is composed of epithelium and a layer within which are embedded nerves, blood vessels, and fat cells. This layer is an example of which tissue?
- A.
  
  Epithelial tissue
- B.
  
  Muscle tissue
- C.
  
  Nervous tissue
- D.
  
  Connective tissue
Correct Answer
D. Connective tissue

Explanation
The heart is lined with a tissue called the epicardium, which is composed of epithelium and a layer within which are embedded nerves, blood vessels, and fat cells. This layer is an example of connective tissue because it contains various components such as nerves, blood vessels, and fat cells that provide support and connect different structures within the heart. Connective tissue is characterized by its ability to support, connect, and protect other tissues and organs in the body.
