What are the functions of organelles?
Organelles are the living bodies inside the cells. These are mainly the characteristics of a eukaryotic cell. These show the division of labour at cellular level and carry out all the activities inside a cell. The physiology of a cell can be attributed to the collective functions of these organelles. Each organelle has it's specific function(s). The functions of major organelles can be stated briefly as - Nucleus - stores the genetic material ; controller and director of all cellular functionsEndoplasmic reticulum - structural frame to cell and skeleton of cell ; cell junction formation; secretion ; protein synthesis (rough ER) ; lipid and derivatives are synthesized(smooth ER)Golgi bodies - modification of synthesized materials (ex. proteins and lipids) ; regulation of molecular traffic inside the cell ; secretion (intracellular as well as outside)Mitochondria - site of aerobic respiration as well as synthesis of many useful substances Lysosomes - hydrolytic digestive enzymes active at acidic pH and help in digestion of unwanted,old,dead substanesRibosomes - site of protein synthesisPlastids - store reserve food materials and pigmentsCentrosome - involved in cell division Cilia and flagella - extend outside the cell and help in motility Vacuole - stores excess minerals , water and excretory substances which are transported inside against the concentration gradientCytoplasm - the main arena for all the cellular activites ; polyphasic and crysto - colloidal in natureCell wall - outermost covering ; mechanical support and protection ; permeable in nature ; variable composition among different groups of organismsCell membrane - selectively permeable ; composed of mainly lipids and proteins ; universal layer ; inner to cell membraneBesides these, the microtubules and microfilaments are also present which provide support to the cell and may be involved in motility.
What body parts have same function as organelles?
no body part has the same function as organelles. Organelles are tiny structures found in the cell, for eg. nucleus, mitochondria, cytoplasm, ribosomes, golgi bodies etc... body parts are eg. organs i guess you mean like the heart liver lungs etc... for more info look up wikipedia or sthing mybe google will be enough
What are the parts of an animal cell and its functions?
Animal cells are eukaryotic cells which are surrounded by plasma membrane. It contains the nucleus and organelles that are membrane bound. The cell organelles have a vast range of functions to perform like hormone and enzyme production to providing energy for the cells. Animal cells lack cell wall, a large vacuole and plastids. Due to the lack of the cell wall, the shape and size of the animal cells are mostly irregular. Most of the cells size range between 1 and 100 micrometers and are visible only with help of microscope. Trillions of cells are found in the human body. There are many different types of cells, approximately 210 distinct cell types in adult human body.Fig. Structure of Animal CellComponents of an animal cell are as follows:Cell membrane - forms the outer covering of the cell made up of phospholipids which has polar (hydrophillic) heads and non-polar (hydrophobic) tails and is semi-permeable.Cytoplasm - is a gel-like matrix where all the other cell organelles are suspended inside the cell and ensures the cell doesn't shrink or burst.Nucleus - contains the hereditary material DNA and directs the activities of the cell.Centrioles - organize the microtubules assembly during cell division.Endoplasmic Reticulum - are a network of membranes composed of rough and smooth endoplasmic reticulum.Golgi complex - is responsible for storing, packaging of cellular products.Lysosomes - are enzyme sacs that digest cellular wastes.Microtubules - are hollow rods, function primarily as support and shape to the cell.Mitochondria - is the site for cellular respiration and producers of energy.Ribosomes - are made of RNA and proteins, and are sites for protein synthesis.Nucleolus - is the structure within the nucleus and helps in synthesis of ribosomes.Nucleopore - is the tiny hole in the nuclear membrane, allows the movement of nucleic acids and proteins in/out of the cell.
What cell organelle functions like bones and muscles in the human body?
Microfillaments
Organelles in cells similar to Organs in the body?
well your mitochondria is where the energy is made, ATP is converted into energy and ADP, so let's say it's your muscles. Nucleus controls what happens in your body so let's call it your brain. Chromosomes are DNA when they are about to separate so let's call that your sex organs as they are responsible for reproduction. Golgi Apparatus process proteins and lipids so let's say it's your digestive system. Cell walls only occur in plant cells and serve serve for protection so that's like the bark of a tree (can't think of an animal equivallent as animals don't have cell walls, oh wait, maybe the bones as they are strong and provide support?) Chloroplast again only in plants - it's where the chlorophil does the photosynthesizing maybe they're like skin cells that take sunlight and make vitamin D. Cilia and Flagella are little wavey things that come off the cell and help it move or move things along, maybe a bit like the hairs on your head or the hairs in your nose or ears?
Please can anyone explain how the following organelles work together to preform the life functions of the cell?
you have ap bio too? D:< lol ribosomes produces protein and endoplasmic reticulum modifies it, like finishes the job cuz the protein isnt finished when it leaves the ribosomes golgi bodies release lysosomes to break down macromolecules and other things nucleus creates ribosomes while ribosomes bind to er endoplasmic reticulum ships out the modified protein into the golgi body where it is "accesorized" like if the ER sends out cholesterol golgi adds functional groups like hydroxyl to make hormones, and the golgi body ships it out in vesicles outside the cell same thing as above i guess :P
Organs/parts of the human body compared to the organelles of a cell?
Title pretty much says it all. Here is the list of organelles and a few of my guesses…On my guesses please tell me if I am right and if I am wrong correct me. On the other ones that I just don’t know please tell me what organ and WHY. Thank you for the help!!! Nucleus – Brain (Why: The brain controls the body and hold all the important information. A nucleus controls the movements of a cell and hold the DNA) Ribosome - ? (Not really sure about this one) Plasma Membrane - Skin (Why? Both are the outer most parts and protect cell/ body to some degree.) Mitochondria - ? Lysosome - ? Vacuole - ? Endoplasmic Reticulum - ? Golgi – maybe the our nerves, right? (Doesn’t the golgi send message throughout the cell…a little bit like the nerves in our body) Cytoplasm – Blood? Maybe? Once again not sure. Cytoskeleton - ? Centriole - ? Nucleolus - ? Once again thank for any and all help!!! P.S. please no mean remarks like “You should pay attention in class more” or the ever popular “look it up on Google”
Which cell organelles control most of the activities of a cell?
That's an incorrect question. There ain't any organelles which controls the others. It's just that they all work in a coordinating manner.But we often say that the nucleus controls the cell. However, that's not entirely true.What the nucleus does is just to house the DNA, ribosomes, rRNAs, nuclearproteins required for transcription, DNA repair, organising DNA. As we know, DNA has information which is required for the synthesis of proteins.This goes as per the Central dogma of protein synthesis.DNA → RNA → ProteinProteins are synthesized in cytoplasm & after complete synthesis they r transported to the specific organelles. The proteins which are to be secreted outside the cell or are destined for ER, Golgi, Lysosome, Plasma membrane enter the secretory pathway.Mitochondrial, Chloroplast, Nuclear, Peroxisomal proteins are directly transported to these specific organelles.
