cell oragenells with structure and function
Answers
Answer: Plasma Membrane
The plasma membrane also termed as a Cell Membrane or Cytoplasmic Membrane. It is a selectively permeable membrane of the cell, which is composed of a lipid bi-layer and proteins.The cell membrane functions by providing shape and protects the inner contents of the cell. Based on the structure of the plasma membrane, it is regarded as the fluid mosaic model. According to the fluid mosaic model, the plasma membrane is sub cellular structures, made of a lipid bi-layer in which the protein molecules are embedded.
Cytoplasm
The cytoplasm is present both in plant and animal cells. They are jelly-like substance, found between the cell membrane and nucleus. They are mainly composed of water, organic and inorganic compounds. The cytoplasm is one of the essential components of the cell, where all the cell organelles are embedded. These cell organelles contain enzymes, mainly responsible for controlling all metabolic activity taking place within the cell and are the site for most of the chemical reactions within a cell.
Nucleus
The nucleus is a double-membraned organelle found in all eukaryotic cells. It is the largest organelle, which functions as the control center of the cellular activities and is the storehouse of the cell’s DNA. By structure, the nucleus is dark, round, surrounded by a nuclear membrane. It is a porous membrane (like cell membrane) and forms a wall between cytoplasm and nucleus. Within the nucleus, there are tiny spherical bodies called nucleolus. It also carries another essential structure, called chromosomes.
Endoplasmic Reticulum
The Endoplasmic Reticulum is a network of membranous canals filled with fluid. They are the transport system of the cell, involved in transporting materials throughout the cell.
Mitochondria
Mitochondria are called as the powerhouses of the cell as they produce energy-rich molecules for the cell. The mitochondrial genome is inherited maternally in several organisms. It is a double membrane-bound, sausage-shaped organelle, found in almost all eukaryotic cells.
The double membranes divide its lumen into two distinct aqueous compartments. The inner compartment is called ‘matrix’ which is folded into cristae whereas the outer membrane forms a continuous boundary with the cytoplasm.
Ribosomes
Ribosomes are non-membrane-bound and important cytoplasmic organelles found in close association with the endoplasmic reticulum.
Ribosomal RNA and Ribosomal proteins are the two components that together constitute ribosomes. The primary function of the ribosomes includes proteins synthesis in all living cells that ensure the survival of the cell.
Answer:
there are many cell organelles like mitochondria, lysosome, plastids etc.
there function is to regulate our body those organelles are inside the cell. and they all have different structure and different function.
