Which of these describes a group of cells that perform similar tasks?
A. Tissue
B. Organs
C. Cell membrane
D. Genes
A. Tissue
The correct answer is A. Tissue.
To arrive at this answer, let's break down the options and their descriptions:
A. Tissue: Tissue is a collection of cells that work together to perform a particular function in the body. Different types of tissues, such as muscle tissue or connective tissue, have specific roles and characteristics.
B. Organs: Organs are composed of different types of tissues, and they work together to perform specific functions in the body. Examples of organs include the heart, lungs, and liver.
C. Cell membrane: The cell membrane is a structure that surrounds a cell and controls the movement of substances in and out of the cell. It is an essential component of a single cell, not a group of cells.
D. Genes: Genes are segments of DNA that encode the instructions for building and maintaining an organism. They determine the traits and characteristics of an individual rather than describing a group of cells.
Based on these descriptions, A. Tissue is the most appropriate option as it closely aligns with the definition of a group of cells that perform similar tasks.
