Answer to Question #152725 in Cell Biology for 250300183747

Question

1)enumerate the functions of different organelles of eukaryotic cells (at least 15)
2)enumerate five staining technique that can be used during histological studies

Answer 1

1.Chloroplast-converts sunlight into glucose

2.Vacuole-used for storage

3.Lysosomes-protect cell from invaders; break down worn- out cell part

4.Centrioles-make up cilia and flagella.

5. Nucleus-stores genetic information

6.Rough Endoplasmic Reticulum-Contains a combination of proteins and enzymes. It has a number of ribosomes giving it a rough appearance. Its function is to synthesize new proteins.

7.Ribosomes-link amino acids to form protein

8.Golgi apparatus-processes, sorts, and delivers protein

9.Vesicles-transport materials from place to place within a cel

10.Mitochondria-supplies energy to the cel

11.Cytosketeton-helps position and transport organelles; provides strength; aids in movement

12.Nucleolus-Ribosomal RNA is synthesized from instructions from the DNA

13.Smooth Endoplasmic Reticulum-Synthesizes lipids, detoxifies drugs and poisons, and stores calcium ions

14.Cytoplasm-Jelly-like material present outside the nucleus in which the cell organelles are located

15.Peroxisome-contains enzymes that transfer hydrogen to water, producing hydrogen peroxide as a by product, which is converted into water by other enzymes.

Question 2.

1.Differential Staining - is a staining process which uses more than one chemical stain.

2.Gram Staining - is a technique used to differentiate two large groups of bacteria based on their different cell wall constituents.

3.Acid fast Staining - is a differential stain used to identify acid-fast organisms i.e members of the Genus Mycobacterium.

4.Endospore Staining - is a technique used in bacteriology to identify the presence of endospores in a bacterial sample, which can be useful for classifying bacteria.

5 Simple Staining - is a technique that only uses one type of stain on a slide at a time.
