What is an indication that water is entering cells?
The cell will be swollen. Number of Na and K ions will be different
Why do the epidermal cells have had there edges folded over?
The folds on epidermal cells, called microvilli, increase the cell's surface area for absorption and secretion. This increased surface area allows for more efficient exchange of molecules such as nutrients and waste products with the external environment.
Why are folded membranes in cells more effective than unfolded membranes?
Folded membranes in cells are more effective because they have more surface area. The wider area of space allows for more activity to occur without damage to the cell because of membrane's resistance.
Why does the retina have to be smooth why not wrinkled?
A retina has to be smooth and not wrinkled so the image that is formed by the lens is in focus at all points. If it were wrinkled, some areas of the image would be out of focus; it is smooth to best reflect the light.
Does light pass through the entire thickness of the neural layer of the retina to excite the photoreceptors?
No, light does not pass through the entire thickness of the neural layer of the retina to excite the photoreceptors. Light enters the retina through the transparent layers (like the ganglion cells and bipolar cells) and reaches the photoreceptor layer (rods and cones) where it is absorbed and converted into electrical signals for processing by the brain.
Why are cheek cells wrinkled?
because they are
What is an indication that water is entering cells?
The cell will be swollen. Number of Na and K ions will be different
Which is and indication that water is entering cells?
Fingers looking wrinkled
Which is an indication that water is entering cells [Apex]?
Fingers looking wrinkled [APEX]
Why do some plant leaves become wrinkled?
Some plant leaves become wrinkled due to dehydration, lack of water, or nutrient deficiencies, which can cause the cells in the leaf to shrink and lose their turgidity. This results in the leaf appearing wrinkled or wilted.
What causes fingers to look wrinkled after soaking in warter?
Water enters the cells in the skin.
Which suspension would leave red blood cells wrinkled and reduced in volume?
Red blood cells in 10% salt solution
Are the cells flat or do they have thickness?
Cells typically have thickness, as they are three-dimensional structures. While some cells may appear flatter due to their shape or function, they still have some degree of thickness, with various organelles and structures contained within them.
Why do some plants have wrinkled leaves?
Some plants have wrinkled leaves due to a lack of water or nutrients, which can cause the cells in the leaves to shrink and wrinkle. This can also happen as a natural response to stress or environmental conditions.
Which suspension would contain red blood cells that would appear wrinkled and reduced in volume?
A hypertonic suspension would cause red blood cells to appear wrinkled and reduced in volume. This is because in a hypertonic solution, there is a higher concentration of solutes outside the red blood cells compared to inside, leading to water leaving the cells and causing them to shrink and lose their usual shape.
In some cells the plasma membrane is folded outward into multiple small projections called?
microvilli
Why do the epidermal cells have had there edges folded over?
The folds on epidermal cells, called microvilli, increase the cell's surface area for absorption and secretion. This increased surface area allows for more efficient exchange of molecules such as nutrients and waste products with the external environment.
