Human Cells ,Biomas and specie evolution

 A human cell is a basic unit of life that is responsible for carrying out various functions in an organism. A human cell has a membrane that separates it from its environment and regulates the movement of substances in and out of the cell. A human cell also has a nucleus that contains genetic material and controls gene expression. A human cell has various organelles that perform specific tasks, such as mitochondria for energy production, ribosomes for protein synthesis, and lysosomes for waste disposal. A human cell can communicate with other cells through chemical signals or physical contact. A human cell can divide and reproduce through mitosis or meiosis. A human cell can differentiate into different types of cells, such as nerve cells, muscle cells, or blood cells. A human cell can also die in a controlled manner through apoptosis. Human cell Biomass The distribution of cell biomass in the human body is dominated by muscle and fat cells, while red blood cells, platelets, and w...

Functions of 15 organelles of a cell:

Image
  Here are the functions of 15 organelles of a cell: Plasma Membrane : The plasma membrane is a selectively permeable membrane that separates the cell from its environment and regulates the movement of substances in and out of the cell  Cytoplasm : The cytoplasm is a gel-like substance that fills the cell and contains all the organelles. Nucleus : The nucleus is the control center of the cell that contains genetic material and regulates gene expression Endoplasmic Reticulum : The endoplasmic reticulum is a network of membranes that transport proteins and lipids throughout the cell  Mitochondria : Mitochondria are organelles that produce energy in the form of ATP through cellular respiration  Plastids : Plastids are organelles found only in plant cells that are involved in photosynthesis and storage Ribosomes : Ribosomes are organelles that synthesize proteins Golgi Apparatus : The Golgi apparatus is a stack of membranes that modifies, sorts, and packages proteins and...

15 difference between prokaryotes and eukaryotic cells

  Here are 15 differences between prokaryotic and eukaryotic cells Nucleus : Prokaryotic cells lack a nucleus, while eukaryotic cells have a well-defined nucleus that contains genetic material. Size : Prokaryotic cells are generally smaller than eukaryotic cells  . Membrane-bound organelles : Prokaryotic cells lack membrane-bound organelles, while eukaryotic cells have membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus  . Cell wall : Prokaryotic cells have a cell wall made of peptidoglycan, while eukaryotic cells have a cell wall made of cellulose or chitin . Flagella : Prokaryotic flagella are simple in structure and rotate like a propeller, while eukaryotic flagella are more complex in structure and move in a whip-like motion. Reproduction : Prokaryotic cells reproduce through binary fission, while eukaryotic cells reproduce through mitosis and meiosis. Ribosomes : Prokaryotic ribosomes are smaller than eukaryotic ribosomes. DNA :...
