Structure and Function of Cell Organelles
Terms in this set (16)
What are the functions of the Nucleus and what is it similar to?
The Nucleus is kind of like the brain or the mayor of the cell. It controls all activity within the cell.
What is the cell membrane (describe and provide an analogy)?
The cell membrane is only found in animal cells. It can be similar to city borders because it controls what goes in and out of a cell.
What is the Cell Wall and what would happen without it?
The Cell Wall is only found in plant cells. It gives the plant its structure and protects it overall. Without it, plants wouldn't be as hard as they are now.
What is the Mitochondria and what can it be compared to?
The Mitochondria generates the cell's required energy. It is often compared to power plants.
What is the Smooth ER (give an example of what it could be like)?
The Smooth ER acts as the cell's storage. It stores and creates steroids. It also stores ions which your cells may need at a later time making it kind of like a treasure chest.
What is the Rough ER and how does it differ from the Smooth ER?
The Rough ER is very important in the synthesis and packaging of proteins. It's different from the Smooth ER in managing different molecules (protein). The Rough ER is also made up of Ribosomes.
What are Lysosomes and what can they be compared to?
Lysosomes break down excessive macromolecules in order to keep them from building up in the cell. Think of it like a toilet.
What is the Golgi Apparatus and what is the relationship between it and the ER and the Ribosomes?
The Golgi Apparatus transports goods created by the ER and Ribosomes kind of like a post office would transfer mail.
What is the Centrioles and where is it in the cell?
The Centrioles helps the cell when it comes time for it to split. The Centrioles is found near the Nucleus.
What are Ribosomes and where can they be found?
The Ribosomes help make proteins, they can be found on the ER.
What is the Chloroplast, which cells can it be found, and what does it require to do its function?
The chloroplast is basically where the photosynthesis happens in plant cells. In order for it to happen, it requires carbon dioxide, water, and obviously, sunlight.
What is the Vacuole and what would happen without it?
The Vacuole may store water, nutrients, food, and sometimes waste in order to keep the cell alive. It also gives the plant its shape. Without it, there wouldn't be a place in which cells can store certain things and plants wouldn't be healthy.
Give an example of how different cell organelles work together.
1. Rough ER and Ribosomes: (Ribosomes make up Rough ER).
2. Nucleus, Ribosomes, Rough ER, and the Golgi apparatus: All contribute in the process of making proteins.
Which cell organelles help protect the cell?
Cell Membrane: Similar to a wall, keeps the cell protected from the outside.
Lysosomes: Keeps macromolecules from building up.
How do plant cells differ from animal cells?
Chloroplasts in plant cells: Not in animal cells because animals don't need photosynthesis.
Cell Wall in plant cells: Plants need a Cell Wall because they don't have bones unlike most animals.
Vacuole: The Vacuole in plants are much bigger because they need to store water. The vacuole in plant cells makes up almost 90% of the cell volume.
List the cell organelles from important to least important (Opinion).
1. Nucleus (brain)
2. Mitochondria/Chloroplast (power)
3. Cell Wall, Cell Membrane, Lysosomes (Protect the cell)
4. ER and Ribosomes (Protein production)
5. Golgi Apparatus (Transportation)
6. Vacuole (Storage)
