Cell Structure
Cells are the basic unit of life, and they are made up of various organelles, each with its own specific function. The following table summarizes the key organelles found in a cell:
| Organelle | Structure | Function | Image |
|---|---|---|---|
| Nucleus | Contains the cell’s genetic material (DNA) | Controls cell growth and reproduction | [Image of a nucleus] |
| Ribosomes | Small, round structures found in the cytoplasm | Synthesize proteins | [Image of a ribosome] |
| Endoplasmic reticulum | A network of membranes that extends throughout the cell | Transports materials within the cell and synthesizes lipids and proteins | [Image of the endoplasmic reticulum] |
| Golgi apparatus | A stack of flattened sacs | Modifies, sorts, and packages proteins and lipids | [Image of the Golgi apparatus] |
| Mitochondria | Rod-shaped organelles with a double membrane | Produce energy for the cell | [Image of a mitochondrion] |
| Lysosomes | Small, membrane-bound sacs | Digest waste materials and cellular debris | [Image of a lysosome] |
| Vacuoles | Membrane-bound sacs that store materials | Store water, food, and waste products | [Image of a vacuole] |
| Chloroplasts | Found only in plant cells | Carry out photosynthesis and produce food for the cell | [Image of a chloroplast] |
Cell Function
Cells are the fundamental units of life, and they perform a vast array of functions that are essential for the survival and proper functioning of organisms. These functions can be broadly categorized into two main types: metabolic functions and genetic functions.
Metabolic functions involve the chemical reactions that occur within cells to obtain energy, synthesize molecules, and remove waste products. Genetic functions involve the storage, transmission, and expression of genetic information.
Essential Cell Functions, Cell Structure And Function Vocabulary Review Answer Key
- Energy production:Cells obtain energy from nutrients through processes such as cellular respiration and photosynthesis.
- Synthesis of molecules:Cells synthesize a wide range of molecules, including proteins, lipids, carbohydrates, and nucleic acids, which are essential for cell growth, repair, and function.
- Removal of waste products:Cells remove waste products, such as carbon dioxide and urea, through processes such as diffusion and active transport.
- Storage of genetic information:Cells store genetic information in the form of DNA and RNA.
- Transmission of genetic information:Cells transmit genetic information from one generation to the next through cell division.
- Expression of genetic information:Cells express genetic information through the process of protein synthesis.
- Communication:Cells communicate with each other through chemical signals, electrical signals, and physical contact.
- Movement:Cells can move through their environment using structures such as flagella and cilia.
- Reproduction:Cells can reproduce themselves through the process of cell division.
These essential cell functions contribute to the overall functioning of the cell by providing the energy, molecules, and genetic information necessary for cell growth, repair, and reproduction. They also allow cells to communicate with each other and respond to their environment.
