What are the parts of a cell(everything inside a cell)? Define their functions also.
Answers
1. Nucleus : Regulates all cell activities
2.Cell Membrane : Is made out of phospholipids and proteins.
3.Mitochondrion : Site of cellular respiration "power house"
4.Lysosome : Suicide Sacks that contain digestive enzymes
5. Rough Endoplasmic Reticulum : Contains Ribosomes, transports proteins and other materials
6.Smooth Endoplasmic Reticulum : Contains no ribosomes, stores proteins
7.Gogi complex (apparatus) : Processes and packages proteins
8. Nucleuolus : Dark spot of chromatin in the nucleous where ribosomes are produced
9.Cytoplasm : Colloid that contains water and nutrients and supports the organelles
10. Organelles : The parts of a cell with a particular function
11.Prokaryotic : Cells with no true nucleus and no membrane bound organelles
12. Eukaryotic : Cells that contain a true nucleus and membrane bound organelles
13. Centrioles : Only in animal cells, aid in cell division
14. Ribosomes : Produce Proteins
15. Chloroplast : Found only in plants, site of photosynthesis
16. Vacuoles : Large storage sacks found mainly in plants
17. Cell Wall : Structure in plants made of cellulose that is outside of the cell membrane
18. Chromatin : Thin strands of DNA and proteins found in the nucleus of a cell.
Cell Smallest unit of life
19. Cytoskeleton : Long protein filaments in the cytosol that support the cell.
Thank u
Hope this will help u
Answer:
●Cell membrane- Regulate the entry and exit of required substances into the cytoplasm.
●Cytoplasm- Holds all cell organelles and performs regulatory functions of cell with help of ions and coordination of organelles.
●Nucleus- Contains genetic material and controls the whole cell through signals.
●Nuclear membrane - Regulate the entry and exit of substances into the nucleus.
●Mitochondria- Powerhouse of cell, ATP synthesis takes place here.
●Endoplasmic Reticulum - Protein and fat formation, cellular detoxification.
●Golgi apparatus- Glycosylation of protein and fat.
●Lysosome- known as suicidal bag, help in digestive activities. Destroy harmful substances and dead tissue.
●Ribosome- Take part in protein synthesis.
●Cytoskeleton - Provides mechanical support the cell.
●Vacuoles(in plants)- Store excess water and waste materials and performs turgor activities.
●Plastids(in plants) - Contains chlorophyll and other pigments and performs photosynthesis.
●Centriole(in animals) - Performs regulatory functions during cell division.
hope this will help you.
