Major Cell Structures: Cell Structure And Function Crossword Puzzle Answer Key
Eukaryotic cells, which are found in all plants, animals, and fungi, have a complex structure consisting of various organelles. Each organelle has a specific function and contributes to the overall functioning of the cell.
- Cell Membrane:Regulates the entry and exit of substances from the cell.
- Cytoplasm:Contains the organelles and provides a medium for cellular processes.
- Nucleus:Houses the cell’s DNA and controls gene expression.
- Ribosomes:Synthesize proteins.
- Endoplasmic Reticulum:Modifies and transports proteins.
- Golgi Apparatus:Sorts and modifies proteins.
- Mitochondria:Generate energy for the cell.
- Lysosomes:Break down waste materials and damaged organelles.
Cell Membrane
The cell membrane is a thin, flexible layer that surrounds the cell and acts as a barrier between the cell and its surroundings. It regulates the entry and exit of substances from the cell, maintaining the cell’s internal environment.
Cytoplasm, Cell structure and function crossword puzzle answer key
The cytoplasm is a gel-like substance that fills the cell and contains all the organelles. It provides a medium for cellular processes and allows organelles to interact with each other.
Nucleus
The nucleus is the control center of the cell. It contains the cell’s DNA, which stores the genetic information necessary for the cell to function and reproduce. The nucleus also controls gene expression, which is the process by which DNA is converted into proteins.
Ribosomes
Ribosomes are small, protein-synthesizing organelles found in the cytoplasm. They read the genetic information in DNA and assemble amino acids into proteins, which are essential for cell growth and function.
Endoplasmic Reticulum
The endoplasmic reticulum is a network of membranes that extends throughout the cytoplasm. It plays a role in protein synthesis and modification. The rough endoplasmic reticulum contains ribosomes on its surface, while the smooth endoplasmic reticulum lacks ribosomes.
Golgi Apparatus
The Golgi apparatus is a complex of flattened membranes that modifies and sorts proteins. It receives proteins from the endoplasmic reticulum and modifies them by adding carbohydrates and other molecules. The Golgi apparatus then packages the proteins into vesicles for transport to their final destination.
Mitochondria
Mitochondria are bean-shaped organelles that are responsible for energy production in the cell. They contain their own DNA and ribosomes, and they produce adenosine triphosphate (ATP), the cell’s main energy currency.
Lysosomes
Lysosomes are small, sac-like organelles that contain digestive enzymes. They break down waste materials and damaged organelles, maintaining the cell’s internal environment.
