What is the name of the control center that directs the activities of the cell?
What is the name of the control center that directs the activities of the cell?
nucleus
What part of the cell directs cell activity?
Nucleus
Is the control center of the cell it directs the cell’s activities?
control center of the cell that directs the cells activities. it contains the chemical instructions that directs all the cells activities and determines the cells characteristics. the “brain” or “boss” of the cell. a thin covering that protects the nucleus.
Which cell part is like the control center and is in charge of the cell?
What is the most important part of a cell?
The nucleus is the most important part of a cell.Esfand 4, 1390 AP
What is the most important cell organelle?
The nucleus is one of the most important organelles in a cell. It is often the largest organelle in animal cells, but this is not always the case. Nuclei contain the genetic material called DNA that is responsible for controlling and directing all cell activities.
What are the two most important organelles?
Organelle Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
What cell organelles are found in both cells?
They are involved in making the cell divide. Centrioles are found near the nucleus but are not seen when the cell is dividing. Centrioles are found in all animal cells, but only lower forms of plant cells. Peroxisomes – Peroxisomes small vesicles distributed throughout the cell.
What is the meaning of cell organelles?
In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function. The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive.
What cell packages proteins?
Among the many parts of a cell, the Golgi apparatus performs this job. It modifies and packages proteins and lipids made within the cell, and sends them out to where they are needed.Mordad 15, 1397 AP
What controls what goes in and out of the cell?
The cell membrane controls what goes in and out by having protein channels that act like funnels in some cases and pumps in other cases. Passive transport does not require energy molecules and happens when a funnel opens in the membrane, letting molecules flow through.Esfand 22, 1397 AP
How the cell is like a factory?
A cell can be thought of as a “factory,” with different departments each performing specialized tasks. A cell’s plasma membrane regulates what enters or leaves the cell. The CYTOPLASM includes everything between the cell membrane and the nucleus.
How is a cell like a factory answers?
The cytoplasm serves like a factory floor because it houses all the organelles and the cell activities. Ribosomes act like factory workers as they build the proteins inside the cell. In general, these organelles, together with the other cell structures work altogether and operate like a system.
Who invented cell?
Robert Hooke
What would a cell wall be in a factory?
The cell wall is the outermost lining of the cell. Found only in plant cells, it protects the cell and maintains it’s shape. Like the cell wall, the walls of the factory protect the factory workers,protection, and maintain the building structure.
Where can you compare the cell membrane?
Answer. Cell membrane can be compared to the front doors of a building because the front doors allow things to go in and out just like cell membrane. They are also like plastic bag according to Cell theory. They also protect the cell from bad things like security Guard.Mehr 15, 1399 AP
What can cells be compared to?
Cells are Like Cars You can compare the windshield and windows to plasma membranes, since they protect the inside of the car from invaders like insects and dirt.Farvardin 9, 1397 AP
What is the cell membrane in a cell City?
The nucleus controls all of the activities of the cell as city hall controls all the activities in of the city. 2. The cell membrane is a thin, flexible envelope that surrounds the cell. It allows the cell to change shape and controls what goes into and out of the cell a.
How a city is like a cell?
A city border is like a cell membrane because it allows what comes in and out of the city. The cell membrane is inside the cell wall just like a city border. Steel grinders are like a cytoskeleton because they are the structure of the city.
Why is Golgi body important for the cell?
The Golgi apparatus is integral in modifying, sorting, and packaging these substances for cell secretion or for use within the cell. It primarily modifies proteins delivered from the rough endoplasmic reticulum, but is also involved in the transport of lipids around the cell, and the creation of lysosomes.Mehr 9, 1396 AP
What is the analogy of the cell membrane?
The cell membrane is like a security guard, because the cell membrane controls what goes in and out of a cell like a security guard controls who goes in and out of the gate. 4. Cell Wall -Supports and protects the cell while still letting materials pass through it.
What type of cell is a cell membrane?
All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components.
What does a cell represents in real life?
Answer. Cells provide structure and function for all living things, from microorganisms to humans. Scientists consider them the smallest form of life. Cells house the biological machinery that makes the proteins, chemicals, and signals responsible for everything that happens inside our bodies.Shahrivar 7, 1399 AP
What is the cell membranes function?
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
Why do plant cells need cell walls?
Plant cells are actively involved in water transportation, and thus plant cell wall ensures that the cell does not burst due to over expansion as water flows in (internal turgor pressure). It helps to maintain the shape and osmolarity of thecells and acts as defense against pressure due to inflow of water.Azar 20, 1391 AP
What would happen if animals have cell wall?
Therefore if an animal cell had a cell wall, it would not be able to do all of its usual activities, for example, run, eat, or do any of the usual necessities as sufficient as possible, as having a cell wall in animal cell would make them stiff and not do any of these activities.Esfand 4, 1396 AP
