To review:
The given blank space in the statement, “After each description, fill in the appropriate term: “workbenches” of the cell: ______; comes in rough and smooth forms: ______; site of ribosomes production: _______; a stack of flattened membranous sacs: _______; outermost layer of plant cells: ______; ferries blueprints for protein production from the nucleus to the cytoplasm: ________.”
Introduction:
A cell is composed of various organelles that play a variety of roles in order to maintain the overall functions of the cell. These organelles not only play their role but also regulate the functions of other organelles, that is, they are constantly interacting with each other in order to function.
For example, protein synthesis is initiated by transcription of deoxy ribonucleic acid (DNA) into messenger-ribonucleic acid (mRNA) inside the cell that is exported to the cytoplasm; ribosome gets attached to mRNA and starts the process of translation. This peptide reaches endoplasmic reticulum for folding and modification and then transported to Golgi apparatus where it is sorted, packaged, and transported further.
This way organelles interact and function among themselves.

Group of answer choices Golgi apparatus Cell wall Endoplasmic reticulum membranearrow_forwardBriefly describe the structure and function of these cellular structures/organelles: endoplasmic reticulum, ribosomes, Golgi apparatus, mitochondria, lysosomes, peroxisomes, cytoskeleton, cell fibres, centrosome, centrioles, and cell extensions.arrow_forward
- Write a short story about your life as a chemical message/protein that was created by the nucleus. Describe your journey through the cell after the nucleus has given the instructions to have you made. Describe how each organelle affects your journey as you travel through the cell and, ultimately, through the cell membrane. Organelles you should mention include the nucleus, nuclear membrane, nucleolus, ribosomes, endoplasmic reticulum, cytoplasm, Golgi body, and plasma/cell membrane. Be creative and describe as many organelles as you wantarrow_forwardChoose all the right sentences: Proteins are needed for many cellular functions such as damage cells Nuclear pores prevent materials to move between the cytosol and the nucleus Ribosomes serves as the site of biological protein synthesis The nucleolus and chromosomes are surrounded by nucleoplasm Nucleoplasm also supports the nucleus by helping to maintain its shape The nucleolus helps to synthesize ribosomes free ribosomes located on the surface of rough endoplasmic reticulum plasma membrane separates the contents of the nucleus from the cytoplasmarrow_forwardMatch the cell organelle with its function. Put responses in the correct input to answer the question. Select a response, navigate to the desired input and insert the response. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse.

- Which of these organelles is directly involved in the synthesis, editing, or modification of cell components? Mark all that apply. Group of answer choices actin (8 nm) microfilaments cilia flagella free ribosomes Golgi complex (Golgi apparatus) intermediate (10 nm) filaments lysosomes microtubules (25 nm) peroxisomes proteasomes rough endoplasmic reticulum smooth endoplasmic reticulum spliceosomesarrow_forwardLet's say there is a protein that needs to be made and then exported out of the cell by exocytosis. Put the order of events in the correct order. Transport by vesicle to the plasma membrane for exocytosis. Process new protein in the rough ER. Transcribe into mRNA in nucleus. Transport by vesicle from the rough ER to the golgi apparatus for further processing, modifying, and sorting. Translate mRNA into protein on a ribosome attached to the rough ER in the cytoplasm.arrow_forwardDescribe the following as seen under the compound microscope.

Show the following organelles and describe their role in making, modifying, or transporting the protein: Nucleus Ribosomes Rough ER Vesicles Golgi apparatus Where the protein goes and what it does when it's finished.arrow_forwardFrom memory, draw two eukaryotic cells. Label the structures listed here and show any physical connections between the internal structures of each cell: nucleus, rough ER, smooth ER, mitochondrion, centrosome, chloroplast, vacuole, lysosome,microtubule, cell wall, ECM,microfilament, Golgi apparatus,intermediate filament, plasma membrane, peroxisome, ribosome, nucleolus, nuclear pore, vesicle,flagellum, microvilli, plasmodesma.arrow_forwardInsulin is a protein that is produced by pancreatic cells and secreted into the bloodstream. Which of the following options correctly lists the order of the structures in the endomembrane system through which insulin passes from its production to its exit from the cell? rough ER, transport vesicles, Golgi apparatus, vacuole, cell membrane rough ER, Golgi apparatus, smooth ER, cell membrane rough ER, transport vesicles, cell membrane rough ER, lysosomes, transport vesicles, cell membranearrow_forward
