a.

Summary Introduction

To explain:

The use of lactophenol cotton blue dye, to stain the cytoplasm of a protozoan Amoeba proteus, enhances which property of the microscope.

Introduction:

The staining or dying of the specimen is performed to clearly visualize and distinguish the parts of the cells under microscope. The stain highlights the structures of the cell. Staining of the specimen supports the examination of different types of organelles and different types of tissues. The dyes are specific to cellular structure, so different types of dyes are used for the identification of different organelles of the cell.

b.

Summary Introduction

To determine:

The type of microscope used to visualize a viral pathogen present in the biopsy of the patient’s lung.

Introduction:

Microscopy is the study of a specimen with the help of a microscope. The microscope helps to identify and study the external and internal structures of a specimen. A microscope also confirms the presence of microbes in the given sample.

Summary Introduction

To determine:

The type of microscope to visualize the presence of multiple organisms within a specimen.

Introduction:

Different types of the organisms vary in their shape and size. The presence or absence of appendages also differentiates the types of microorganisms. The microscopes are used to identify and confirm the presence of the microorganisms in the given sample.

Summary Introduction

To determine:

The type of microscope to visualize the organelles within a eukaryotic cell.

Introduction:

Plant cells and animal cells are called as the eukaryotic cells. The eukaryotic cells possess the characteristic “true nucleus”. Various cellular organelles are also the part of eukaryotic cells. The organelles of eukaryotic cells are membrane-bound and perform a particular function.
