Who is father of cell?
The cell was first discovered by Robert Hooke in 1665 using a microscope. The first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830s.
How was the cell discovered class 9?
Solution: in 1665, Robert Hooke discovered cells while examining a thin slice of cork through a self-designed microscope. He observed that the cork resembled the structure of a honeycomb consisting of numerous tiny compartments. The minuscule boxes are referred to as cells.
Where are proteins Synthesised inside the cell for Class 9?
ribosomes
Who discovered nucleus of the cell?
Robert Brown
Where is the nucleus located in a cell?
The cell’s nucleus is in the middle of the cell’s cytoplasm, the liquid that fills the cell. The nucleus may not, however, be right in the middle of the cell itself. Taking up about 10 percent of the cell’s volume, the nucleus is usually around the center of the cell itself.
What is the meaning of nucleus?
the central part
What is the function of endoplasmic reticulum?
The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.
What are the two main functions of endoplasmic reticulum?
The endoplasmic reticulum (ER) is a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism. The diverse functions of the ER are performed by distinct domains; consisting of tubules, sheets and the nuclear envelope.
Which one is correct for mitochondrion?
The mitochondrion (plural mitochondria) is a membrane-bound organelle found in the cytoplasm of eukaryotic cells. It is the power house of the cell; it is responsible for cellular respiration and production of (most) ATP in the cell.
What is the main function of cytoplasm in a cell?
What is the important function of cytoplasm? The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.
