Cell Structure and Function You are an oxygen molecule that has just entered a body cell. In the space provided below, describe all of the structures you see in the cell. Also describe what function each structure is performing in the cell. Each of the following structures should be included in your discussion: a. Plasma membrane b. Cytoplasm c. Nucleus d. Nuclear membrane e. Nucleolus f. Mitochondria 8. Ribosomes h. Rough endoplasmic reticulum 1. Smooth endoplasmic reticulum J. Golgi apparatus k Lysosomes L Centrioles m. Chromatin . Secretory vesicle Date

Answer 1

1.plasma membrane : its function is protecting cell from surrounding and regulates the movement of substances in and out of the cell .It is selectively permeable membrane for ions and organic molecules.

2.cytoplasm:it contains molecules like enzymes which are useful for metabolic activity and break down of waste .cytoplasm also give shape to the cell and keeps organelles in place.

3.Nucleus:- nucleus contain genetic material like DNA which transfers genetic information in daughter cell during cell division.

4.Nuclear membrane:- it protects nucleus and nuclear material from surrounding substances present in cytoplasm.

5.Nucleolus:-its function is to rewrite ribosomal ribonucleic acid(rRNA) and combine it with protein which for incomplete ribosome.

6.Mitochondria:-it is energy house of cell at it produces energy (ATP) for cellular activities .It also consists extra nuclear genetic material.

7.Ribosome:- it is useful in synthesis of protein which is needed for many cellular function, growth ,damage repair and many chemical processes.

8.Rough endoplasmic reticulum:-it plays central role in protein synthesis.

9.smooth endoplasmic reticulum:- it synthesize lipid, steroid hormones, detoxification of harmful metabolic byproducts and storage and metabolism of calcium within the cell.

10.Golgi apparatus:-it modify, sort and package proteins for secretion.it also plays role in transport of lipids around the cell and creation of lysosomes.

11.Centrioles:-it's main function is to play role in cell division. It separates chromosomes by spindle fibres formed by centrioles during cell division.

12.Chromatin:-role of chromatin is to pack DNA efficiently in nucleus and protect DNA structure and sequences.

13.Secretory vesicles:-they move molecules, secrete substances,digest materials or regulates the pressure in the cell.
