What are the organelles revealed by an electron microscope?
Organelles that can be visualized using an electron microscope include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, peroxisomes, and cytoskeleton components like microtubules and microfilaments. Each of these organelles has a specific structure and function within the cell that can be observed at high resolution with an electron microscope.
Why is an electron microscope uselful when studying bacteria?
An electron microscope is useful when studying bacteria because it offers higher magnification and resolution compared to a light microscope. This allows for detailed examination of the ultrastructure of bacteria, including their cell wall, membrane, and internal organelles, which can reveal important information about their morphology and function.
What color is a centrioles?
Centrioles are typically colorless and do not have a distinct color. They are small, cylindrical organelles found in animal cells, usually appearing as pairs near the nucleus. Their primary function is to organize microtubules during cell division.
What organelles are identical to centrioles?
Basal bodies found in eukaryotic cells are identical to centrioles in terms of structure and function. Basal bodies are involved in organizing microtubules within the cell, playing a role in cell division and the formation of cilia and flagella.
What was the instrument that made cell exploration possible microscope?
The microscope was the instrument that made cell exploration possible. By allowing scientists to observe and study cells at a magnified level, the microscope revolutionized our understanding of the structure and function of cells.

What is the function of the lens in an electron microscope?
The lens in an electron microscope focuses and magnifies the electron beam to produce high-resolution images of tiny objects.

Centrioles are typically colorless and do not have a distinct color. They are small, cylindrical organelles found in animal cells, usually appearing as pairs near the nucleus. Their primary function is to organize microtubules during cell division.
What of the function of centriole?
two rod-shaped bodies near the nucleus; the basic of cilia.Centrioles are organelles present in animal What_do_centrioles_do. Plant cells lack centrioles but possess an analogous region called microtubule organizing region having same function as centrioles . centrioles organize mitotic apparatus which consists of asters and spindle fibers which help in division of chromosomes
Does an electron microscope need electricity?
Yes, electron microscopes require electricity to operate. They use electrons to generate images at a very high resolution, which requires a high voltage electrical source to accelerate the electrons. Without electricity, an electron microscope would not be able to function properly.
Two membrane less cell organelles are?
Two membrane-less cell organelles are ribosomes and the nucleolus. Ribosomes are involved in protein synthesis, while the nucleolus is responsible for producing ribosomal RNA and assembling ribosomal subunits. Both organelles lack a membrane and are essential for cell function.
What is the instrument used in studying cells?
Microscope is the instrument used in studying cells, allowing scientists to view cells in detail and observe their structure and function. Different types of microscopes, such as light microscopes and electron microscopes, are used depending on the level of detail needed for the study.
Cell structures that function in cell division are?
centrioles
What is the function of centrious?
Centrioles are cylindrical organelles found in eukaryotic cells, primarily involved in cell division. They play a crucial role in organizing the mitotic spindle during mitosis and meiosis, which ensures proper chromosome segregation. Additionally, centrioles are involved in the formation of cilia and flagella, helping in cellular movement and signaling. Their function is essential for maintaining cellular structure and facilitating the replication process.
Why might a microscopist who specializes in the use of microscopes to examine specimens use a light microscope instead of an electron microscope?
An electron microscope requires that the subject be dead to function. In order to receive a picture, the specimen must be coated in chemicals and put into a vacuum, a process which will kill any living specimen. A light microscope, although not as detailed, will allow the scientist to observe living specimens.
What is the function for centrioles?
to synthesise aster that will become spinder fibre
