What best describes the organelles in a cell?
An organelle is a structure within the cytoplasm of a eukaryotic cell that is enclosed within a membrane and performs a specific job. Organelles are involved in many vital cell functions. Organelles in animal cells include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles.
Which statement best describes the cells?
The statement that best describes the cell theory is seen in choice C: all living organisms are composed of basic units called cells.
What are the organelles in a cell called?
Cells are membrane-bound groups of organelles that work together to allow it to function. Some of the major organelles include the nucleus, mitochondria, lysosomes, the endoplasmic reticulum, and the Golgi apparatus. Plant cells also include chloroplasts, which are responsible for photosynthesis.
What is the best cell organelle?
Mitochondria: The Best Cell Organelle.
What statement best describes the cell membrane?
Which statement best describes the cell membrane? The protective outer layer that controls what enters and leaves the cell.
Which best defines homeostasis?
Homeostasis is any self-regulating process by which an organism tends to maintain stability while adjusting to conditions that are best for its survival.
What are the organelle functions?
What’s found inside a cell
|Smooth Endoplasmic Reticulum (SER)||Lipid production; Detoxification|
|Rough Endoplasmic Reticulum (RER)||Protein production; in particular for export out of the cell|
What organelle is least important?
What organelle is the least important? The ribosome may be the smallest organelle in the cell, but it plays an important part. The ribosomes are vital to the cell; they make proteins for the cell to survive. Without the nucleus making the ribosomes, the cell would die.
What is the function of each cell organelle?
What is cell organelle?
|Cell Organelle||Biological Function||Factory Part|
|Nucleus||DNA Storage||Files and blueprints management|
|Ribosome||Protein synthesis||Machine to product toys|
|Rough ER||Protein production and modification||Coordination of toy production line and decoration|

What is an organelle example?
Membrane-bound organelles are cellular structures that are bound by a biological membrane. … Examples of membrane-bound organelles are nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes, and vacuoles.
How do organelles function together in cellular processes?
Much of a cell’s efforts go toward making proteins. Proteins carry out many important functions in the body. … Cell organelles must work together to carry out protein synthesis, utilize proteins within the cell, and transport them out of the cell.
How do organelles know what to do?
Organelles are complex groups of molecules, arranged in the way that electromagnetic interactions tell them to arrange themselves. They don’t know what to do: they just react the way chemistry (and physics) requires.
What is cell organelle simple definition?
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
What is an organelle and give two examples of organelles?
The nucleus, the mitochondrion, the chloroplast, the Golgi apparatus, the lysosome, and the endoplasmic reticulum are all examples of organelles. Some organelles, such as mitochondria and chloroplasts, have their own genome (genetic material) separate from that found in the nucleus of the cell.
Which organelles in the cell have their own DNA discuss about these cellular organelles in detail?
Mitochondria: Both plant cells and animal cells possess mitochondria. It has its own DNA and plays a met role in the synthesis of enzyme and production of energy.
What is an organelle quizlet?
organelle. a tiny cell structure that carries out a specific function within a cell. nucleus. the control center of the cell that directs the cell’s activities; it contains the chemical instructions that direct all the cell’s activities (DNA)
What do organelles do for the cell give 2 examples including their functions?
Core organelles are found in virtually all eukaryotic cells. They carry out essential functions that are necessary for the survival of cells – harvesting energy, making new proteins, getting rid of waste and so on. Core organelles include the nucleus, mitochondria, endoplasmic reticulum and several others.
What organelle holds water?
Vacuole. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.
What is the function of cell organelles quizlet?
Controls cell’s activities. Also stores cell’s genetic material (DNA) as chromatin (DNA coiled around protein complexes). The DNA contains the coded information for producing proteins.
Why do cells have organelles quizlet?
They make proteins, which carry out many of the functions inside of a cell. All living things need proteins to function, so these organelles are very important.
