If i were an Organelle Exploration. I would be a Nucleus. Write a paragraph about your choice of Organelle. Provide the answers

to these questions within your
paragraph. 1) Which cell type would you be? (2) Which organelle would you be? (3) What is your function within the cell? (4) How many others of you are in the cell? (5) What would happen yo the cell if you were not there? (6) Which human body system do you most resemble and why?. I posted a pic of my paragraph that i have written can anyone let me know if its good or if i need to fix it or add more details. If i need to add more details or fix my paragraph could you help me fix it please and thank you.

Answer:

I would be a nucleus in skin cells. My function would be to protect the genetic material inside me and the genetic material will be replicated and transcribed inside me. As I would be a skin cell, hence I will only have one nucleus.

If I were not present in the skin cell, the DNA would not be protected and changes would occur in it. Important proteins will not be formed if I were not there. New skin cells will not be able to form if I were absent. Mitosis will also not occur.

TEA [102]

Complete question:

Although most solutes that enter or exit the cell are relatively small (inorganic ions, sugars, or amino acids), occasionally the movement of larger molecules into or out of the cell is required. For example, certain cells secrete proteins, such as pancreatic cells that secrete insulin. Other cells take up food particles or even entire cells, such as lymphocytes in your immune system. Transport of such large materials into and out of the cytosol cannot be accomplished by transport proteins in the plasma membrane. The transport of large molecules is accomplished by bulk transport via exocytosis and endocytosis. Like other forms of active transport, bulk transport requires an input of energy. Before beginning this tutorial, watch the segment of the Membrane Transport animation on exocytosis and endocytosis. Observe the role that vesicles play in the transport of materials into and out of the cell.

Part A

Sort the phrases into the appropriate bins depending on whether they describe exocytosis, endocytosis, or both.

a. decreases the surface area of the plasma membrane

b. requires fusion of vesicles with the plasma membrane

c. forms vesicles from inward folding of the plasma membrane

d. transported substances never physically cross the plasma membrane

e. increases the surface area of the plasma membrane

f. requires cellular energy

g. secretes large molecules out of the cell

Answer:

a. -->  ENDOCYTOSIS

b. -->EXOCYTOSIS

c.--> ENDOCYTOSIS.

d. --> BOTH

e. --> EXOCYTOSIS

f. --> BOTH

g. --> EXOCYTOSIS

Explanation:

To answer the question, first, we need to know the meaning of endocytosis and exocytosis.

Endocytosis and exocytosis process refers to molecules transport mediated by vesicles. It occurs from and into the cell and needs energy to happen because it is active transport.

  • Cells can export many substances in vesicles or vacuoles that originate in specific organelles like, for instance, the Golgi complex. Organelles form new vesicles or vacuoles with substances destined for exportation and send them forward to the membrane. When they get there, they fuse to the cell membrane, releasing all their content to the extracellular space. When fussing, the vesicle membrane increases the size of the cellular membrane. This process is <u>exocytosis</u>, and its direction is always from the inside of the cell to the outside.
  • But there is also another vesicle-mediated transport that occurs from the exterior to the cell interior, the <u>endocytosis process. </u>It happens when the cell imports material from the extracellular space through the invagination of the membrane, producing a new vesicle that surrounds the incoming material. The invagination ends in strangulation of the membrane, releasing the new vesicle in the cytoplasm. This process decreases the size of the cellular membrane because it uses part of it to engulf the material.

Now that we know these concepts, we can sort the phrases into the appropriate bins.

a. decreases the surface area of the plasma membrane. ENDOCYTOSIS, because the new vesicles are formed using the cell membrane

b. requires fusion of vesicles with the plasma membrane. EXOCYTOSIS, because vesicle needs to fuse to the cell membrane to release the carrying material

c. forms vesicles from inward folding of the plasma membrane. ENDOCYTOSIS. Refers to the invagination process of the cell membrane. It only occurs during endocytosis

d. transported substances never physically cross the plasma membrane. BOTH. Substances are too big or too many to be physically transported through the cell membrane

e. increases the surface area of the plasma membrane. EXOCYTOSIS. Occurs when the vesicle fuses the cell membrane to release the content to the exterior.  

f. requires cellular energy. BOTH of them, because they are active transport.

g. secretes large molecules out of the cell. EXOCYTOSIS. The direction is from the interior of the cell to the exterior. These are exportation molecules.

Which statement is true about the environment of urban areas
emmasim [6.3K]

The promise of jobs and prosperity, among other factors, pulls people to cities. Half of the global population already lives in cities, and by 2050 two-thirds of the world's people are expected to live in urban areas. But in cities two of the most pressing problems facing the world today also come together: poverty and environmental degradation.
