What zone of a root tip increases the surface area for water and dissolved mineral uptake?
The zone of a root tip that increases surface area for water and mineral uptake is the root cap region, specifically the zone of maturation or elongation where root hairs are formed. Root hairs are small, finger-like projections that significantly increase the root's surface area for absorption.
What else can I help you with?
As a cells volume increase is what happens to the proportional amount of surface area?
As a cell's volume increases, its surface area also increases, but at a slower rate. This is because surface area scales with the square of the diameter, while volume scales with the cube. Consequently, larger cells have a lower surface area-to-volume ratio, which can limit the efficiency of nutrient uptake and waste removal. This relationship is a key factor in cellular size constraints and the necessity for cell division in larger organisms.
What typically increases faster as a cells grows surface area or volume?
As a cell grows, its volume increases faster than its surface area. This is because volume is proportional to the cube of the radius (or size), while surface area is proportional to the square. Consequently, larger cells have a higher volume-to-surface area ratio, which can limit the efficiency of nutrient uptake and waste removal. This relationship often influences cell division, as cells must maintain a manageable size to function effectively.
Is turgor important for mineral uptake?
Yes, turgor pressure is important for mineral uptake in plants. It helps in the movement of water and minerals from the soil into the plant roots through osmosis. Turgor pressure also maintains cell rigidity and structure, which is essential for the proper functioning of the root system in absorbing minerals.
Why is the mucosa of the intrapulmonary bronchus folded?
The folding of the mucosa in the intrapulmonary bronchus increases the surface area for gas exchange by providing more space for the diffusion of gases between the air in the lungs and the blood vessels. This increased surface area allows for more efficient oxygen uptake and carbon dioxide release in the respiratory system.
Why does the root need root hairs for the uptake of water and minerals?
Root hairs increase the surface area of the root for greater absorption of water and minerals. This allows the root to access a larger volume of soil for nutrients and water uptake, contributing to the plant's overall growth and nutrition.
What trace mineral is involved in the regulation of glucose uptake?
Potassium is the mineral involved in the regulation of glucose uptake.
Is as cell surface area increases cell volume increases faster true?
Yes, as cell surface area increases, the cell volume increases at a faster rate. This is because the surface area to volume ratio decreases as the cell grows larger, which can affect the efficiency of nutrient uptake and waste removal within the cell.
WHAT Vitamin increases THE amount of iron IN THE BLOOD?
Vitamin C increases iron uptake.
Do roots take in the water needed by the plants and also mineral salts?
Yes roots roots do both,root hairs absorb minerals dissolved in water .Water uptake from the soil by root cells is passive, and also follows osmotic gradients caused by the mineral nutrients
What hormone increases glucose uptake into muscle and adipose tissue?
Insulin
What part does water play in absorption of mineral salts from the soil?
Water dissolved mineral salts in the soil, facilitating their uptake by plant roots through a process called osmosis. Without water, plants would not be able to absorb essential nutrients from the soil. Additionally, water helps transport these nutrients from the roots to the rest of the plant for growth and development.
Why is the Casparian strip advantageous in terms of selective mineral uptake?
The Casparian strip is advantageous for selective mineral uptake because it forces water and minerals to pass through the plasma membrane of endodermal cells, where they can be selectively absorbed. This helps regulate the types and amounts of minerals that enter the plant, preventing toxic buildup and ensuring efficient nutrient uptake.
As a cells volume increase is what happens to the proportional amount of surface area?
As a cell's volume increases, its surface area also increases, but at a slower rate. This is because surface area scales with the square of the diameter, while volume scales with the cube.

Is turgor important for mineral uptake?
Yes, turgor pressure is important for mineral uptake in plants. It helps in the movement of water and minerals from the soil into the plant roots through osmosis. Turgor pressure also maintains cell rigidity and structure, which is essential for the proper functioning of the root system in absorbing minerals.
Why respiration rates increase in root hair cells during the uptake of mineral ions?
due to active transport system
How does the presence of hair cells of roots enables effecient absorption of water?
They develop a cytoplasmic hair-like elongation which increases its surface area for more absorption. It also has a large number of mitochondria which provides energy needed for the active uptake of minerals.
Benefit of large water uptake in plants?
Large water uptake in plants allows for proper hydration, transportation of nutrients, and maintenance of turgor pressure in cells. It also aids in cooling the plant through transpiration and contributes to various physiological processes such as photosynthesis and growth.
