Pick two structures from an animal cell and explain how they work together to keep the cell alive
Cell Membrane:
The cell membrane is a crucial structure in an animal cell that serves as a protective barrier. It consists of a lipid bilayer embedded with proteins that control the passage of substances in and out of the cell. The membrane is selectively permeable, meaning it allows only certain molecules to pass through while blocking others. This selective permeability is essential for maintaining the internal environment of the cell and regulating the exchange of nutrients, ions, and waste products.
Cytoplasm:
Cytoplasm is the fluid-like substance that fills the interior of the cell and surrounds the organelles. It is made up of water, salts, and organic molecules that provide support to the cell and help maintain its shape. The cytoplasm is where many cellular processes occur, such as protein synthesis, metabolism, and energy production. Organelles like the mitochondria, endoplasmic reticulum, and ribosomes are suspended in the cytoplasm and carry out specialized functions to keep the cell alive.
Together, the cell membrane and cytoplasm work in harmony to create an optimal environment for the cell to function and thrive. The cell membrane regulates the transport of substances in and out of the cell, while the cytoplasm provides structural support and a medium for cellular activities to take place. Without these two structures working together, the cell would not be able to maintain its internal balance, perform essential functions, or survive in its environment.
