Answer: The arrow is pointing to
the nucleus
. The function of this organelle that it controls the activities of the cells .
What is the structure at the arrow?
The shaft
is the primary structural element of the arrow, to which the other components are attached. Traditional arrow shafts are made from strong, lightweight wood, bamboo or reeds, while modern shafts may be made from aluminium, carbon fibre reinforced plastic, or a combination of materials.
What is the function of this organelle?
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 the structure and function of each organelle?
| Organelle Main function Structure | nucleus DNA maintenance, controls all activities of the cell, RNA transcription double-membrane compartment | vacuole storage, transportation, helps maintain homeostasis single-membrane compartment |

Which arrow is pointing to the nucleus?
The red line outlines the cell’s boundary. The nucleus is indicated by
the red arrows
. The yellow arrow points to the nucleolus which is very prominent in this cell type. Basophilic substances in the cytoplasm are indicated by the black arrows.
What are the 5 parts of an arrow?
- Shaft: The long spine of the arrow. …
- Fletching: The plastic vanes or feathers on an arrow. …
- Arrowhead: The point of the arrow. …
- Nock: A slotted plastic tip located on the rear end of the arrow that snaps onto the string and holds the arrow in position.
What will stop an arrow?
For what its worth, some things I have experienced:
Loose hanging carpet, especially 2 layers separated by 4+”
is pretty good for stopping fletched field point arrows. The first layer catches the fletching to stop the arrow, so soft fletches like duravanes take a beating (but can be straightened with a heat gun).
What is the most important organelle?
The nucleus
is the most important organelle in the cell. It contains the genetic material, the DNA, which is responsible for controlling and directing all the activities of the cell. All the RNAs needed for the cell are synthesised in the nucleus.
Why is an organelle important?
Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve
specific functions to keep an organism alive
, organelles serve specific functions to keep a cell alive.
What are 3 different functions of an organelle?
| Cell Organelle Biological Function Factory Part | Nucleus DNA Storage Files and blueprints management | Mitochondrion Energy production Powerplant | Ribosome Protein synthesis Machine to product toys | Rough ER Protein production and modification Coordination of toy production line and decoration |

What is the relationship between the structure and function of cell organelles?
Answer:
Organisms can only function properly if the structure goes along with the function it is to perform
. Cells have different organelles which work differently from one another to help maintain the cells active functioning. Within a cell, there are different types of proteins to carry out different functions.
What is the difference between the structure and function of cell organelles?
Organisms are composed of cells, and these cells have specific structures within in them that allow them to carry out their functions. These structures are called Organelles. …
Organelles perform different functions within a cell
, and this is called the Division of Labour.
Which organelle is called suicidal bags of cell?
50 years ago, Christian de Duve introduced the term “suicide bags” to describe
lysosomes
(1), the organelles containing numerous hydrolases, which were, until the discovery of the ubiquitin-proteasome system, thought to be responsible for the major part of the intracellular turnover of proteins and other macromolecules …
What does a nucleus look like?
Through the microscope, the nucleolus looks like
a large dark spot within the nucleus
. A nucleus may contain up to four nucleoli, but within each species the number of nucleoli is fixed. After a cell divides, a nucleolus is formed when chromosomes are brought together into nucleolar organizing regions.
Where does nucleus lie Why is it important?
The nucleus is located
toward the center of the cell because it controls all of the cell’s movements, the cell’s feeding schedule and the cell’s reproduction
. Its central location enables it to reach all parts of the cell easily.
Why does the nucleus stain darker?
Methylene blue has a string affinity for both DNA and RNA. When it comes in contact with the two, a darker stain is produced and can be viewed under the microscope. …
When a drop of methylene blue is introduced
, the nucleus is stained, which makes it stand out and be clearly seen under the microscope.
