Cilia and flagella are the structures that sweep materials across the cell surface. These hair-like projections are made up of microtubules and are capable of rhythmic beating, which helps in moving fluids, mucus, or other substances along the cell surface. In certain cells, such as those lining the respiratory tract, cilia play a crucial role in clearing debris and pathogens.
What else can I help you with?
Which cell organelle sweep material across a surface?
Cilia are the cell organelles that sweep material across a surface. They are hair-like structures that protrude from the surface of some eukaryotic cells and beat in a coordinated way to move materials along the cell's surface.
Apical epithelial cell structures functions in the movement of materials across the surface of the cell?
Apical epithelial cell structures, such as microvilli and cilia, increase the surface area of the cell for absorption and movement of substances. Microvilli aid in absorption, while cilia facilitate the movement of materials along the cell surface, such as in the respiratory tract for mucus clearance.
Why can a cell get only so large?
There is a surface area to volume ratio, as a cell gets larger it becomes harder and harder to transport materials inand out of the cell. There has to be enough surface area to supply the cell with all of the materials that it needs for survival.
Why is surface area an important factor in limiting factor in limiting cell growth?
The materials entering or leaving a cell need to pass through the cell surface.
Are ribosomes the function to move materials across the cell?
No. Ribosomes are the site of protein synthesis.
Which cell organelle sweep material across a surface?
Cilia are the cell organelles that sweep material across a surface. They are hair-like structures that protrude from the surface of some eukaryotic cells and beat in a coordinated way to move materials along the cell's surface.
What are numerous threadlike organelles that protrude from the surface of a cell and are packed in tight rows?
Cilia are numerous threadlike organelles that protrude from the surface of a cell and are packed in tight rows. They are involved in cell movement and the movement of materials across the cell surface.
Apical epithelial cell structures functions in the movement of materials across the surface of the cell?
Apical epithelial cell structures, such as microvilli and cilia, increase the surface area of the cell for absorption and movement of substances. Microvilli aid in absorption, while cilia facilitate the movement of materials along the cell surface, such as in the respiratory tract for mucus clearance.

There is a surface area to volume ratio, as a cell gets larger it becomes harder and harder to transport materials inand out of the cell. There has to be enough surface area to supply the cell with all of the materials that it needs for survival.
True or False The smaller a cell is the more difficult it is for the cell to move enough materials across its cell membrane?
False. A smaller cell has a higher ratio of surface area to volume, making moving the amount of required nutrients simpler.
How does the cell transport materials across the cell membrane?
a cell transports things across the cell membrane from areas of high concentration to ares of low concentration
What would happen to a cell if materials could not move across the cell membranes?
it will died
How are related the surface are of a cell to the transport of materials?
The surface area of a cell is directly related to the transport of materials because a larger surface area allows for more efficient exchange of materials with the cell's environment. Increased surface area provides more space for transport proteins and channels to facilitate the movement of nutrients, waste products, and signaling molecules into and out of the cell. This is important for maintaining cellular processes and overall cell function.
What 2 materials move across the cell membrane?
waste and nutrients
Why is surface area an important factor in limiting factor in limiting cell growth?
The materials entering or leaving a cell need to pass through the cell surface.
What does the rate at which materials move through the cell membrane depend upon?
the cell's surface area
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
