An animal cell (left) and a plant cell (right) are shown. which organelle, labeled x in the diagram, is found in both plant and animal cells? a. the cell wall b. the cell membrane c. mitochondria d. ribosomes

The rigth answer is cell membrane.

A cell membrane distinguishes a fundamental cellular structure formed from a double layer of phospholipids associated with other lipids, proteins and carbohydrates.

The membrane of the cell, also known as the plasma or cytoplasmic membrane, is a biological membrane (biomembrane) that separates the interior of all cells from the external environment.

The plasma membrane, cytoplasmic membrane or plasmalemma delimits the cytoplasm of the cell. Organelles are surrounded by a single cell membrane (peroxisomes, lysosomes, endoplasmic reticulum, dictyosomes, vacuole) or double (nucleus, plastids).

the answer is cell membrane on edg

Explanation:

the answer is a or when it says crossing over

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
