PLANT / ANIMAL
CELL PART
DESCRIPTIONEXPLANATION
Cell MembraneIt provides shape to the cell. It is semi-permeable, regulating the entry and exit of substances, namely solutes and ions.The cell membrane is also known as the plasma membrane. It is the outermost covering of the animal cell. It protects the cell and regulates the entry and exit of substances, namely ions and solutes.
Cell WallIt provides protection, shape and rigidity to the cell. It is freely permeable, allowing substances in the form of solutions to enter and leave the cell without any hindrance.The cell wall is the outermost covering of the plant cell made up of cellulose, and surrounds the cell membrane. It protects the cell, provides mechanical support and is responsible for maintaining pressure inside the cell.
CentrosomeIt initiates and regulates cell division. It also helps in forming spindle fibres, with the help of asters.The centrosome of the animal cell contains one or two centrioles, and is surrounded by microtubules or the centrosphere. It initiates and regulates cell division.
ChloroplastIt is a plastid, containing a pigment called chlorophyll. This chlorophyll captures energy from sunlight and helps in the manufacture of food by the process of photosynthesis.The chloroplast of the plant cell is a green-colored plastid. Chlorophyll contained in the chloroplast captures energy from sunlight and helps in the manufacture of food by the process of photosynthesis.
ChromoplastIt is a plastid, containing pigments such as xanthophyll (yellow in color) and carotene (orangish-red in color). These pigments impart color to flowers and fruits of plants.The chromoplast of the plant cell is a plastid that is colored differently in different cells. It contains pigments such as xanthophyll (yellow in color) and carotene (orangish-red in color). It imparts color to flowers and fruits of plants.
CytoplasmIt is the house of all metabolic activities and functions in the cell. In other words, it contains most of the cell organelles, each of which perform a specific function.The cytoplasm is composed of a mixture of water and soluble organic & inorganic compounds, and contains most of the cell organelles. It is the house of all metabolic functions and activities of the animal cell. 
Endoplasmic ReticulumIt provides support to the cell. It also helps in the synthesis and transport of proteins and fats.The endoplasmic reticulum consists of tubular structures (convoluted tubules) lying near the nucleus. It provides support to the plant cell and the animal cell. It is of two types, namely the smooth endoplasmic reticulum (does not have ribosomes attached to it) and the rough endoplasmic reticulum (has ribosomes attached to it).Rough Endoplasmic Reticulum
Golgi ApparatusIt synthesizes and secretes certain substances, namely hormones and enzymes. It also helps in the formation of acrosome of sperm.The golgi apparatus of the animal cell consists of flat vesicular structures placed one on top of the other. It synthesizes and secretes certain substances, namely hormones and enzymes.Golgi Apparatus
LeucoplastIt is a plastid. It helps in the storage of starch.The leucoplast of the plant cell is a colorless plastid. It helps in the storage of starch.
LysosomeIt performs intracellular digestion. It also helps in destroying foreign substances.The lysosome of the animal cell is a membranous sac budded off from the golgi apparatus, and contains several types of enzymes. It performs intracellular digestion and destroys foreign substances.
MitochondrionIt is the site of ATP (Adenosine triphosphate) synthesis. It also synthesizes respiratory enzymes.The mitochondrion of the cell has two layers of membrane, of which the inner one is folded to form cristae. It is the site of ATP (Adenosine triphosphate) synthesis.Mitochondrion
Nuclear MembraneIt is semi-permeable, allowing substances to enter and leave the nucleus of the cell. It also provides protection to the nucleus of the cell.The nuclear membrane is the covering of the nucleus of the cell, and has numerous pores. It allows substances to enter and leave.
NucleolusIt synthesizes proteins by producing and storing RNA (Ribonucleic acid). At the same time, it orders ribosomes to synthesize proteins.The nucleolus is contained in the nucleus of the cell, and is round in shape. It synthesizes proteins by producing and storing RNA (Ribonucleic acid).
NucleoplasmIt contains chromatin fibres, which are made up of DNA (Deoxyribonucleic acid). After cell division takes place, these chromatin fibres undergo certain structural changes, and are called chromosomes. These chromosomes carry the hereditary information of the genes.The nucleoplasm is a dense fluid containing chromatin fibres, which are made up of DNA (Deoxyribonucleic acid). After cell division takes place, these chromatin fibres undergo certain structural changes, and are called chromosomes. These chromosomes carry the hereditary information of the genes.
NucleusIt controls and coordinates all the activities and functions of the cell. It plays a vital role in cell division.The nucleus is the most important part of the cell, and contains large amounts of DNA (Deoxyribonucleic acid). It controls and coordinates all the activities and functions of the cell.
RibosomeIt is known as the 'site of protein synthesis in the cell', and synthesizes proteins. It is chiefly composed of RNA (Ribonucleic acid).The ribosome is chiefly composed of RNA (Ribonucleic acid). It synthesizes proteins.
VacuoleIt helps in the storage of water and several other substances, namely food, waste products and pigments. It also provides turgidity to the cell.The vacuole of the plant cell is a very large and abundant vesicle. It is filled with fluids, and helps in the storage of water and other substances.
