Cell Organelle And Cell Theory Quiz

The statement "Cell is the basic unit of life" is true. Cells are the smallest structural and functional units of all living organisms. They are responsible for carrying out essential functions necessary for life, such as growth, reproduction, and metabolism. Cells contain genetic material, organelles, and a cell membrane that regulates the movement of substances in and out of the cell. All living organisms are made up of one or more cells, making the cell the fundamental building block of life.

The Cell Theory states that all living things are made of cells. This theory, proposed in the mid-19th century, revolutionized the understanding of biology by establishing that cells are the basic structural and functional units of life. It states that cells are the building blocks of all living organisms and that all cells arise from pre-existing cells. This theory laid the foundation for the field of cell biology and has been supported by numerous observations and experiments over the years.

Robert Hooke was the first person to see a cell and named it a cell (a room). He observed cork and noticed a line of cells that resembled small rooms, leading him to coin the term "cell." This discovery was a significant milestone in the field of biology and laid the foundation for our understanding of cells as the basic unit of life.

The answer is false because according to the cell theory, which is a fundamental principle in biology, all cells arise from pre-existing cells. This theory states that cells are the basic units of life and that new cells are formed through the division of pre-existing cells. This process is known as cell division and is essential for growth, development, and the maintenance of living organisms. Therefore, it is incorrect to say that all cells don't come from pre-existing cells.

The cell is the fundamental building block of all living organisms. In multicellular organisms, cells with similar structures and functions group together to form tissues. Different tissues then combine to create organs, which perform specific tasks. Organs work together in organ systems, and the coordinated function of all organ systems makes up the complete organism. This hierarchical organization is a fundamental principle in biology.

The correct answer is 1 cell; Multi: 2+ cells. This answer accurately describes the difference between unicellular and multicellular organisms. Unicellular organisms are made up of only one cell, while multicellular organisms are composed of two or more cells. This explanation clearly states the correct answer without any unnecessary information.

Mitochondria is called the power house of the cell because it is responsible for producing the majority of the cell's energy in the form of ATP (adenosine triphosphate) through cellular respiration. This organelle contains its own DNA and is involved in various metabolic processes, including the breakdown of carbohydrates and fatty acids to generate energy. Without mitochondria, cells would not have the necessary energy to carry out their functions, making it an essential organelle for cellular survival and functioning.

M. Schleiden found out that all plants are made of cells.

Leeuwenhoek used a simple light microscope and observed microorganisms. This is supported by the fact that he is known as the "Father of Microbiology" and made significant contributions to the field by discovering and documenting various microorganisms, such as bacteria and protozoa, using his self-made microscopes.

T. Schwann stated that all animals have cells. This statement is in line with the cell theory, which states that all living organisms are composed of cells. Schwann's contribution to the cell theory was his observation that animals, like plants, are also made up of cells. This discovery helped to solidify the understanding that cells are the basic building blocks of all living things.
