Question

recalling prior knowledge of cells. consider the following guiding questions as you read the passage on the next slide. what functions must the cell perform? how is a cell like a system? what does it mean that the form of a cells structures often predicts their function?

Explanation:

Cells perform functions like metabolism, growth, and reproduction. They are like systems as they have various components (organelles) that work together for the cell's survival. The form - function relationship means that the shape and structure of cell parts are related to what they do. For example, red blood cells are biconcave to maximize oxygen - carrying capacity.

Answer:

1. Cells perform functions such as metabolism, growth, reproduction, and maintaining homeostasis.
2. A cell is like a system because it has multiple organelles (like a system has components) that interact and work together to keep the cell alive and functioning. For example, the mitochondria produce energy, the nucleus controls cell activities, etc.
3. The form of a cell's structures often predicts their function means that the shape, size, and composition of a cell part are adapted to its role. For instance, nerve cells have long axons to transmit electrical signals over long distances.
