Which organelle’s function is primarily locomotion?

Movement of eukaryotic flagella in real time and slow motion. flagellum plural flagella hairlike structure that acts primarily as an organelle of locomotion in the cells of many living organisms.

Which structure in the cheek cells did you observe?

The nucleus at the central part of the cheek cell contains DNA. When a drop of methylene blue is introduced the nucleus is stained which makes it stand out and be clearly seen under the microscope.

Which of the following is a correctly labeled image of a cheek cell?

Question: Which of the following is a correctly labeled image of a cheek cell What is the function of the nucleus in the Euglena cells you observed?

What is the function of the vacuoles?

A vacuole is a membrane-bound cell organelle. In animal cells vacuoles are generally small and help sequester waste products. In plant cells vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.

What is the function of the cell wall in the onion?

The cell wall of an onion cell functions as a structural part of the cell offering support and protection for the fluids and organelles inside.

What do you call an organelle which is responsible for the locomotion of the cells?

rough endoplasmic reticulum is covered with ribosomes has folds that are flat sacs smooth endoplasmic reticulum has folds that are tubular. flagellum. locomotion sensory. protein.

Why is the process of cell division important for an onion?

Why use onion roots for viewing mitosis? The roots are easy to grow in large numbers. cells can be observed. The chromosomes can be stained to make them more easily observable.

What is the color of the iodine solution in the diffusion bag before and after dialysis?

What was the color of the iodine solution in the diffusion bag before and after dialysis? The iodine solution was reddish brown before dialysis and did not change color during dialysis.

Do cheek cells have vacuoles?

Since human cheek cells are animal cells they do not have a cell wall. … Also human cheek cell has several small vacuoles. A prominent nucleus is found at the center of the cell.

What is the function of cheek cells?

The primary function of cheek cells is to secrete proteins called mucins which are a key component of mucus. When combined with saliva from the salivary glands mucins help to keep the interior of the mouth moist. This helps with the chewing softening enzymatic digestion and swallowing of food.

How does the structure of a cheek cell relate to its function?

How does the shape help the function? cheek cell round and flat with a small nucleus These cells line the inside of the mouth. The shape creates a flat smooth surface so food does not get caught on the skin.

How do you observe cheek cells under a microscope?

What is the cheek cell?

The tissue that lines the inside of the mouth is known as the basal mucosa and is composed of squamous epithelial cells. These structures commonly thought of as cheek cells divide approximately every 24 hours and are constantly shed from the body.

What is the function of the cell wall in the onion cell you looked at quizlet?

What is the function of the cell wall in the onion cell you looked at? It protects the cell and provides shape and support.

What is the purpose of the vacuole in a plant cell?

The vacuole plays an important role in the homeostasis of the plant cell. It is involved in the control of cell volume and cell turgor the regulation of cytoplasmic ions and pH the storage of amino acids sugars and CO2 and the sequestration of toxic ions and xenobiotics.

What are the functions of the central vacuole in plants?

Filling this space is an organelle called a central vacuole which is full of water. Bounded by a single membrane this organelle functions as a combination of reservoir waste dump storage region and even as a means of keeping the cell in shape.

What is the role of vacuoles in unicellular organism?

they are small in animal cells and large in plant cells.in plant cells vacuoles are full of cell sap and provide turgidity and rigidity to the cell.in single celled organisms like amoeba the food vacuole contain the food item that amoeba has consumed.in some unicellular organisms specialised vacuoles also play .

Why can’t you see the vacuole in onion cells?

The central vacuole takes up most of the volume of the cell. … Like animal cells the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can’t see it but it is pressed against the inside of the cell wall.

What are the functions of cell wall Class 9?

The functions of cell wall are:
  • It provides protection to the cell and prevents from any physical damage.
  • It provides structure to the cell.
  • It prevents from osmotic bursting.
  • It protects the protoplasm against mechanical injury.
  • It controls intercellular transport.

Does onion cell have cell wall?

An onion is a multicellular (consisting of many cells) plant organism.As in all plant cells the cell of an onion peel consists of a cell wall cell membrane cytoplasm nucleus and a large vacuole. The nucleus is present at the periphery of the cytoplasm.

Which of the following is not a function of the vacuole in plants?

Osmotic pressure and turgidity is maintained by vacuoles. They store toxic metabolic by-products or end products of plant cells. Such vacuoles are thrown out of the cell by exocytosis. Thus the incorrect answer is option B.

What are the functions of organelle?

What’s found inside a cell
Organelle Function
Mitochondrion Energy production
Smooth Endoplasmic Reticulum (SER) Lipid production Detoxification
Rough Endoplasmic Reticulum (RER) Protein production in particular for export out of the cell
Golgi apparatus Protein modification and export

How do organelles work together to perform specific functions?

Proteins carry out many important functions in the body. There are two types of proteins: structural proteins and enzymes. … Cell organelles must work together to carry out protein synthesis utilize proteins within the cell and transport them out of the cell.

What is the function of mitosis in a cell that is about to divide?

During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

Why are onion roots used for studying the cell cycle and mitosis?

Determining time spent in different phases of the cell cycle

In plants the roots continue to grow as they search for water and nutrients. These regions of growth are good for studying the cell cycle because at any given time you can find cells that are undergoing mitosis.

Why are some cells in the onion root tip undergoing mitosis quizlet?

Mitosis is just the cell’s nucleus dividing into 2 separate nuclei not the cell. … These plants are selected because whitefish blastula and onion root tip have cells that rapidly divide making it easier to see the different stags of mitosis under a microscope.

What happened to the iodine in the diffusion bag?

What happened to the iodine in the diffusion bag? It diffused out of the diffusion bag and into the beaker. … You tested the solution in the beaker and the solution in the diffusion bag using the biuret test.

Why does the iodine stay in the bag and cross the membrane?

In a cell membrane this is called selective permeability. In other words the iodine can go through the baggie but the starch cannot. The purpose of this experiment is to show that a cell membrane is a type of barrier and is permeable to some substances but may not be permeable to all substances.
