What are like cells grouped together called?
A.
An organ
B.
A system
C.
A membrane
D.
A tissue
The correct answer and Explanation is :
The correct answer is D. A tissue.
Explanation:
In biology, cells that are similar in structure and function are grouped together to form tissues. A tissue is a collection of cells that work together to perform a specific task in the body. For example, muscle tissue is made up of muscle cells that work together to allow movement, while nervous tissue consists of neurons that transmit signals throughout the body.
Types of Tissues:
- Epithelial Tissue: This tissue covers the surfaces of organs, lines cavities, and forms glands. It protects the body from external harm, absorbs substances, and secretes enzymes or hormones.
- Connective Tissue: Connective tissues support, bind, and connect different parts of the body. Examples include bone, blood, and adipose (fat) tissue. These tissues provide structure, store energy, and transport nutrients.
- Muscle Tissue: Muscle tissues are responsible for movement. There are three types: skeletal muscle (voluntary movements), cardiac muscle (heart contractions), and smooth muscle (involuntary movements in organs like the intestines).
- Nervous Tissue: This tissue is made up of neurons and glial cells, which are responsible for receiving, transmitting, and processing nerve impulses. Nervous tissue is essential for communication between different parts of the body.
Why Not the Other Options?
- A. An organ: Organs are made up of multiple tissues working together to perform a specific function. For example, the heart is an organ composed of muscle tissue, connective tissue, and epithelial tissue.
- B. A system: A system is a group of organs working together to perform major bodily functions. For example, the digestive system includes the stomach, intestines, and liver.
- C. A membrane: A membrane is a thin layer of tissue that covers a surface, lines a cavity, or divides a space or organ, but it’s not a group of similar cells.
In summary, cells that are similar in structure and function are grouped together to form tissues, which is why D is the correct answer.
