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?
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 mineral?
because absorption of water takes place by root hairs in the root
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.
Does dissolved minerals enter into the root hair by osmosis not by diffusion?
Dissolved minerals primarily enter root hairs through the process of active transport, where the plant expends energy to move minerals against their concentration gradient. This is a primary mechanism for absorbing essential nutrients such as nitrogen, phosphorus, and potassium. Osmosis and diffusion play a role in water uptake and movement within plant tissues but are not the main routes for mineral absorption.
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
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.
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.
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.
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.
