What is crystallization? Crystallization is the process in which a pure substance is obtained in the form of a crystal from its solution and is called crystallization. A crystal is a solid that is made up of particles arranged in a geometric pattern. The process of forming a crystal from a saturated solution is called […]
Epithelial tissue is a special type of tissue that forms the outer covering of the body (skin), and it also lines the internal organs, such as the mouth, lungs, blood vessels, and intestine. It is made up of closely packed cells with little space between them. It acts as a protective barrier against the entry
Osmosis is the process in which the movement of water molecules takes place from a region of higher water concentration to lower water concentration through a selectively permeable membrane. Osmosis is an important process in our day-to-day life. Living organisms such as plants and animals do osmosis to maintain their lives. For example, plants use
What is mitosis? Mitosis is a type of cell division in which one parent cell divides to form two identical daughter cells. Also, the number of chromosomes in the daughter cell is the same as the parent cell. Each cell contains 23 pairs of chromosomes. It means it has a total of 46 chromosomes that
Mitochondria is also knows as “Powerhouses of the cell” because they produce energy in the form of ATP (Adenosine Triphosphate) to perform cellular activities. The cell need energy to perform various activities like respiration, growth, cell division protein synthesis etc. if we remove mitochondria in eukaryotic cell then cell lose it energy and doesn’t perform
Yes, white flowers may contain pigments but the they are very little in amount and having no colored pigments. That why they don’t show bright color like red, blue, yellow. Another reason is that the petals reflect all the white light and don’t absorb any colored light. so that we see the white flower Reasons
The cell membrane is the outermost membrane of a cell. It is thin and flexible membrane that surrounds the cell and protect it from external environment. It is also called selectively permeable membrane because it regulate the movement of substance in or out though the cell. The Important 5 Function of cell membrane Here The
What is lysosomes and what is contains? Lysosomes is a small sac type membrane that is filled with a powerful digestive enzyme called hydrolytic. It is mainly found in animal cells and destroy or act as a cleaning agents of a cell. It helps to destroying infected cells by foreign particles, digesting unwanted material or
For example : Combination : 2H₂ + O₂ → 2H₂O Decomposition: 2H₂O ──Electricity──▶ 2H₂ + O₂ You can clearly see that in first one , hydrogen and oxygen atoms are combine together to form water. But On the second one see that water molecule is decomposed and break down in to hydrogen and oxygen when
What is Cell A cell is the basic unit of a living organism. It means each living organism is made up or one or more cells. That’s why cell is called building blocks of a life. Cell is capable to do all the activities of that is necessary of a life like respiration, growth, reproduction,
