What else can I help you with?
True or false cilia and flagella are cell surface structures that are adapted for respiration?
No, It is not used for respiration instead it is used for the movement or locomotion of body.
Which type of microscope would be used to observe structures on the surface of an individual cell?
A scanning electron microscope (SEM) would be used to observe structures on the surface of an individual cell. SEM uses a focused beam of electrons to scan the surface of a sample, producing high-resolution images of the surface features of the cell.
Why did you iodine to cheek cells structures and what is darkest?
Iodine is used to stain cheek cells during microscopic examination to make the cellular structures more visible and easier to identify. The darkest structures in the cheek cells after staining with iodine would typically be the cell nuclei, which are rich in DNA and thus take up more of the iodine stain.
Flagella are longer and more numerous than cillia?
Flagella are longer than cilia but, not as numerous as cilia. Cilia usually surround the surface of a cell. Flagella are usually found only once (eg. sperm)
In animal-like protists the short threadlike structures that extend from the cell membrane are called what?
The short threadlike structures in animal-like protists that extend from the cell membrane are called cilia. Cilia are used for movement and feeding in these single-celled organisms.
What term is used for the structures of a cell?
organelles
What is used to direct proteins synthesis in the cell?
Sequences of nitrogenous bases in the cell's DNA.
Which transport process does the cell used to direct the contents of the vesicles out of the cell membrane?
Exocytosis
What is used to direct protein synthesis in a cell?
Ribosomes are the 'work stations' that direct that production of proteins. It used mRNA as a blue print.
True or false cilia and flagella are cell surface structures that are adapted for respiration?
No, It is not used for respiration instead it is used for the movement or locomotion of body.
What is the threadlike structures extending from the cell membrane of paramecia?
The threadlike structures extending from the cell membrane of paramecia are called cilia. They are used for locomotion and to help with feeding by creating currents in the water to bring food particles close to the cell.
What are the structures in a Cell that are used for storage of foods and wastes called?
Vacuoles are the structures responsible for storing food and waste in a cell. They are membrane-bound organelles that help maintain cell turgidity, regulate pH balance, and store various molecules.
What contains enzymes that are used to degrade foreign particles as well as cell structures?
Lysosomes contain enzymes that are used to degrade foreign particles as well as cell structures. These enzymes help break down substances such as bacteria, viruses, and damaged organelles within the cell.
What is the cilia in a cell structure?
Cilia are hair-like structures used by some cells for movement.
Is safranin an acidic dye?
Yes, safranin is considered an acidic dye. It is commonly used in histology and microbiology to stain cell nuclei, cytoplasm, and cellulose-rich plant cell walls due to its affinity for acidic components in these structures.
What does a cilia do in an animal cell?
cilia are short hair-like structures used for locomotion (movement)
What is a Direct stain?
A direct stain is a type of dye used in microbiology to color specific structures within cells, allowing for easier visualization under a microscope. It binds directly to cellular components, such as proteins or nucleic acids, providing contrast against the background. Common examples include methylene blue and crystal violet. Direct stains are often used in techniques like simple staining to assess cell morphology and arrangement.
