Chromosomes(:
Genes.
Cells are the smallest structures that can perform all the activities required for life. They contain the necessary components such as DNA, cytoplasm, and organelles to carry out functions like metabolism, growth, and reproduction.
The nucleus plays a key role in directing the activities of a cell. It contains the cell's DNA, which holds the instructions for making proteins that carry out various functions in the cell. By controlling gene expression, the nucleus regulates and coordinates the cell's activities.
These organisms are likely referring to cells. Cells use specialized organelles like mitochondria for energy production and the endoplasmic reticulum for protein synthesis to carry out the activities needed to maintain homeostasis. Specialized internal structures allow cells to perform specific functions efficiently.
Genes are stored in the cell's nucleus in structures called chromosomes. Each chromosome contains long strands of DNA, which are made up of genes that carry the instructions for making proteins and controlling cell functions.

Genes.
The instructions for a cell to carry out its activities are stored in its DNA (deoxyribonucleic acid). DNA contains genes, which are specific sequences that code for proteins, the molecules that perform most cellular functions. These instructions are transcribed into messenger RNA (mRNA), which is then translated into proteins by ribosomes. This process enables the cell to respond to internal and external stimuli and maintain homeostasis.

Genes carry the instructions to make proteins, i think....
A cell is a single unit of life that has all the necessary structures and functions to carry out life activities, such as metabolism, growth, and reproduction. It contains organelles like the nucleus, mitochondria, and ribosomes that work together to support life processes.
Structures in cells that control or carry genes are called chromosomes. Chromosomes are thread-like structures made of DNA and protein that are located in the nucleus of a cell. They contain the genetic information that is passed from one generation to the next.
