What is the basic unit of structure and function in the human body?
The basic unit of structure and function in the human body is the cell. Cells are like tiny building
blocks that make up our body and perform various functions to keep us alive and functioning.
How do cells differ from one another?
Cells vary in size and shape; structure and function are inter-related.
What are the three major parts of a cell?
nucleus, cytoplasm, cell membrane
Define nucleus
Control center of the cell. Contains DNA.
Define Cytoplasm
Consists of organelles, with specific functions, suspended in aliquid called cytosol
Define cell membrane
outer boundary of the cell
Define organelle
any of a number of organized or specialized structures within a living cell.
List functions of the cell membrane
, It controls the movements of substances in and out of the cell, helps maintain the cell's shape
and structure, and allows cells to communicate with each other.
What does selectively permeable mean?
regulates entry and exit of substances
What is the cell membrane made of?
phospholipids and proteins
Explain the major classes of biomolecules found in the plasma membrane.
lipids, proteins, and carbohydrates.
Lipids function
store energy
Proteins function
involved in cell structure, enzyme activity, transportation of molecules, immune defense, and cell
signaling.
carbohydates function
provide energy for cells, help with digestion, absorption of nutrients, and play a role in cell
communication.
