What are the long cellular extensions that propel cells?
The long cellular extensions that propel cells are called flagella and cilia. They are composed of microtubules and are used by cells for movement and sensory functions. Flagella are typically longer and found singly or in small numbers, while cilia are shorter and found in large numbers on the cell surface.
What are the motile cellular extensions found in large numbers in some epithelial cells called?
Cilia are the motile cellular extensions found in large numbers in some epithelial cells. These hair-like structures help move fluid and particles along the cell surface, aiding in processes such as mucociliary clearance in the respiratory tract.
What is a extensions of root epidermis cells that help absorb water?
Root hairs are extensions of root epidermis cells that help increase the surface area of the root for improved absorption of water and nutrients from the soil.
The small bumps shown in this photomicrograph are the site of?
The small bumps shown in the photomicrograph are likely to be cellular protrusions called microvilli. Microvilli are found on the surface of some epithelial cells and serve to increase their surface area for absorption and secretion of substances.
What slender extensions of the plasma membrane that increase its surface area?
Microvilli are slender extensions of the plasma membrane that increase its surface area. They are found in cells involved in absorption, such as in the small intestine, where they help in increasing the efficiency of nutrient absorption.
What are cellular projections?
Cellular projections are extensions of a cell's membrane that serve various functions, such as facilitating communication, movement, and interaction with the environment. Common types of cellular projections include microvilli, which increase surface area for absorption, and cilia or flagella, which aid in locomotion or moving substances across the cell surface. These structures play critical roles in maintaining cellular function and contributing to the overall physiology of tissues and organs.
What are The short extensions of the cell wall called?
The short extensions of the cell wall are called microvilli. They are found on the surface of some cells and serve to increase surface area for absorption and secretion of substances.
What cellular organelle is a projection that moves substances along the surface of a cell?
cilia
What cellular organelle is a projection that moves substances onto epithelial surfaces?
Cilia are cellular projections that move substances along the surface of epithelial cells. They beat in a coordinated manner to propel mucus and other substances across the epithelial surface, aiding in functions such as mucus clearance in the respiratory tract.
What are the long cellular extensions that propel cells?
The long cellular extensions that propel cells are called flagella and cilia. They are composed of microtubules and are used by cells for movement and sensory functions. Flagella are typically longer and found singly or in small numbers, while cilia are shorter and found in large numbers on the cell surface.
What are the motile cellular extensions found in large numbers in some epithelial cells called?
Cilia are the motile cellular extensions found in large numbers in some epithelial cells. These hair-like structures help move fluid and particles along the cell surface, aiding in processes such as mucociliary clearance in the respiratory tract.
What cell are finger-like extensions of the cell surface membrane v?
Finger-like extensions of the cell surface membrane are found in epithelial cells, particularly in the form of microvilli. These structures increase the surface area of the cell, enhancing its ability to absorb nutrients and other substances. Microvilli are commonly found in cells lining the intestines and the kidneys, where they play a crucial role in absorption and secretion.
Is a higher surface area to volume ratio is more efficient for cellular activity?
Yes, a higher surface area to volume ratio is more efficient for cellular activity because it allows for faster exchange of substances with the environment, such as nutrients and waste products. This is important for processes like cellular respiration and nutrient uptake.
What are slender extensions of the plasma membrane that increase its surface area?
Microvilli
What are the cellular organelles located on the cell surface that protrude from the cell and beat and vibrate?
Cilia and flagella are the cellular organelles located on the cell surface that protrude from the cell and beat or vibrate. They are involved in various cellular functions such as movement, sensing the environment, and moving substances across the cell surface.
What are facts about cilia?
Cilia are hair-like structures found on the surface of many cells in the body. They play a role in moving fluids over the cell surface, such as in the respiratory tract to clear mucus and in the reproductive system to move eggs through the fallopian tubes. Cilia are composed of microtubules and are anchored in a structure called the basal body.
True or false fine hairlike extensions on the exposed or free surfaces of some cells are called microvilli?
True. Microvilli are fine hairlike extensions on the surface of some cells that increase the cell's surface area for absorption and secretion.
