Q.) Assume that all the cell organelles are talking inside your body. Write a role play by giving dialogues corrosponding to the different cell organelles of a plant cell, in not less than 1000 words.
The role play should be like a conversation being in between the all cell organelles.
• The best will be marked as the brainliest but the one with improper answer and below the word limit will be reported.
• Please it's really very urgent...!!
Answers
Answer:
Explanation:
Nucleus
'Control Center' of the cell.
Contains the cell's DNA (genetic information) in the form of genes.
Re.
Nucleic Acids
*Sequestration and *replication of DNA.
*Transcription and *modification of RNA.
Contains one or more nucleoli (plural, singular word = nucleolus) whose functions include:
Nucleoli
Biosynthesis of ribosomal RNA (rRNA) and production (assembly) of ribosomes.
2.
Rough Endoplasmic Reticulum (RER)
Consists of many interconnected membranous sacs called cisternae, onto whose external surface ribosomes are attached (distinguishing RER from SER on electron micrographs).
Ribosomes
Produce polypeptides that are then either ...
inserted into the RER membrane, or
moved into the lumen (central region) of the cisternae, or
moved to the Golgi complex and probably onwards from there.
In lumen of cisternae
Produce proteins that are then either ...
retained within vesicles, or
secreted from the cell (via secretory vesicles - see below).
3.
Smooth Endoplasmic Reticulum (SER)
Consists of many interconnected membranous sacs called cisternae (without ribosomes).
Many enzymes are either attached to the surface of the SER or located within its cisternae. Chemical reactions within the SER vary with the type and location of cells. E.g.
helps with protein folding and transport of synthesized proteins
glycosylation - which involves the attachment of oligosaccharides.
disulfide bond formation and rearrangement - to stabilize the tertiary and quaternary structure of many proteins
modification of some drugs e.g. by the cytochrome P450 enzymes in liver cells.
4.
Mitochondria
The main function of mitochondria in aerobic cells is the production of energy by synthesis of ATP. However, mitochondria also have many other functions, including e.g.:
Processing and storage of calcium ions (Ca2+).
Apoptosis, i.e. the process of programmed cell death
Regulation of cellular metabolism
Synthesis of certain steroids
See also the structure of mitochondria and the functions of mitochondria.
5.
Chloroplasts
(plant cells only)
Chloroplasts are the sites of photosynthesis within plant cells.
6.
Golgi Apparatus
The Golgi apparatus modifies, sorts and packages macromolecules for delivery to other organelles or secretion from the cell via exocytosis - see (9.) below.
7.
Lysosomes
Lysosomes (tiny sacs containing enzymes) are the main sites of intracellular digestion. They enable the cell to make use of nutrients. Their functions can be listed as:
Autophagy - digestion of materials from within the cell.
Heterophagy - digestion of materials originating from outside the cell.
Biosynthesis - recycling unwanted products of chemical reactions to process materials received from outside the cell.
Lysosomes also destroy the cell - usually after it has died.
8.
Peroxisomes
(also called "microbodies" - smaller than lysosomes and contain specific enzymes)
Similar to (but smaller than) lysosomes, the metabolic functions of peroxisomes include:
Breakdown of fatty acids by beta-oxidation
Breakdown excess purines to urea
Breakdown of toxic compounds e.g. in the cells of the liver and kidney.
also play a role in the biosynthesis of certain important molecules incl. cholesterol and (in liver cells) bile acids derived from cholesterol.
9.
Secretory vesicles
(sometimes called simply "vesicles")
Transport and delivery of their contents (e.g. molecules such as hormones or neurotransmitters) either into or out of the cell, in both cases via the cell membrane.
Exocytosis - movement of the contents of secretory vesicles out of the cell.
Endocytosis - movement of the contents of secretory vesicles into the cell.
10.
Vacuole
(plant cells only)
Helps maintain turgor pressure pressure (turgidity) inside the cell - which pushes the plasma membrane against the cell wall. Plants need turgidity to maintain rigidity.

Re.
Nucleic Acids
*Sequestration and *replication of DNA.
*Transcription and *change of RNA.
Contains one or greater nucleoli (plural, singular word = nucleolus) whose features include:
Nucleoli
Biosynthesis of ribosomal RNA (rRNA) and manufacturing (assembly) of ribosomes.
Rough Endoplasmic Reticulum (RER)
Consists of many interconnected membranous sacs known as cisternae, onto whose outside floor ribosomes are connected (distinguishing RER from SER on electron micrographs).
Ribosomes
Produce polypeptides which might be then both...
inserted into the RER membrane, or moved into the lumen (crucial region) of the cisternae, ormoved to the Golgi complicated and likely onwards from there.In lumen of cisternae .Produce proteins which might be then both...retained inside vesicles, or,secreted from the cellular (through secretory
vesicles - see below).
3.
Smooth Endoplasmic Reticulum (SER)
Consists of many interconnected membranous sacs known as cisternae (with out ribosomes).
Many enzymes are both connected to the floor of the SER or positioned inside its cisternae. Chemical reactions in the SER range with the sort and vicinity of cells. E.g.
allows with protein folding and delivery of synthesized proteins
glycosylation - which includes the attachment of oligosaccharides.
disulfide bond formation and rearrangement - to stabilize the tertiary and quaternary shape of many proteins change of a few tablets e.g. through the cytochrome P450 enzymes in liver cells.
4.
Mitochondria
The essential characteristic of mitochondria in cardio cells is the manufacturing of power through synthesis of ATP. However, mitochondria additionally have many different features, inclusive of e.g.:
Processing and garage of calcium ions (Ca2+).
Apoptosis, i.e. the system of programmed cellular death.Regulation of cell metabolism.Synthesis of positive steroids.See additionally the shape of mitochondria and the features of mitochondria.
