Question

Describe the function of each organelle.

Answer 1

Ans.

Cell is defined as a basic structural and functional unit of all living forms. The cell organelles represent specialized subunits or structures within a cell, having a specific function, such as mitochondria, nucleus, cytoplasm, and chloroplasts.

-Cytoplasm shows all of the material present in a cell, except nucleus. It provides platform for various cellular activities, such as glycolysis. It also provides shape to the cell and keeps cell organelles in place.

-Chloroplasts are membrane-bound cell organelles, found in photosynthetic organisms. Chloroplasts contain chlorophyll molecules that function in trapping the solar energy and help in the process of photosynthesis.

-Cell wall is a rigid, outermost protecting layer, present in bacteria, fungi, plants, and in some protists. Cell wall provides protection and structural support to the cells due to its rigid nature.

-Centrioles are small cell organelles, found near nucleus of animal cells. These organelles function in formation of spindle fibers at the time of cell division, required for the proper separation of chromosomes in daughter cells.

Answer 2

Answer:

Cytoplasm: Is a semi- fluid substance. It is present between the cell membrane and the nucleus. Water is the main component of the cytoplasm. Cytoplasm dissolve in it the molecules released by organelles present in it. It acts as a reservoir for dissolution of molecules not required instantly by the cell to conduct any metabolic activity except lipids. It can dissolve proteins, glucose etc.  Pathways like glycolysis takes place in cytoplasm.

Chloroplasts: It is a cell organelle found in plants. The function of chloroplast is to carry out photosynthesis in plants. It uses pigment which traps the sunlight. It converts the sunlight energy into chemical energy in the form of ATP and NADPH.

Cell wall: It is the semi- permeable layer outside the plant, fungi, algae and bacteria. It's main function is to provide structural support to the cell. It facilitates the import and outport of molecules in and of the cell necessary for cell function.

Centrioles: They are the cell organelles which are visible during the cell division.The centrioles are the sites where the spindle fibers originate. These spindle fibers gets attach with the each membrane of the chromosome pair and facilitate their separation during cell division.
