Where do root hair cells get their oxygen from?
Root hair cells obtain oxygen from the air spaces in the soil surrounding the plant roots. Oxygen diffuses through the soil and is taken up by the root hairs along with water and nutrients. This oxygen is essential for the cellular respiration and metabolic processes of the root hair cells.
By what mechanism would root cells absorb needed minerals in the soil?
Root cells absorb needed minerals from the soil through a process called active transport. This involves using energy to move molecules against their concentration gradient into the root cells. The specific transport proteins in the root cells facilitate the uptake of different minerals such as ions like nitrate, phosphate, potassium, and others.
Why root tips are placed in 10 percent hydrochloric acid mitotic index?
Root tips are placed in 10% hydrochloric acid to break down the cell walls and release the cells for analysis. The mitotic index is calculated as the ratio of cells in mitosis to the total number of cells examined, providing information on the rate of cell division in the root tip. This method helps to determine the growth activity and health of the plant.
how do the roots absorb oxygen from the soil?
Roots absorb oxygen through tiny openings called root hairs, which allow oxygen to pass through the cell walls and into the root cells. Oxygen diffusion occurs from areas of higher concentration in the soil to lower concentration inside the root cells, enabling the roots to take up the oxygen needed for respiration.
Why we use hcl in mitosis experiment in onion root tip?
Hydrochloric acid (HCl) is used in the mitosis experiment on onion root tips to hydrolyze the pectin in the cell walls, making it easier to separate the cells for analysis. By softening the cell walls, HCl helps release the individual cells, allowing for better visualization of the chromosomes during different stages of mitosis. This process is crucial for accurately counting and identifying cells in various stages of the cell cycle, providing valuable data for studying cell division and growth.
Is the root of the nail from which keratinized cells grow.?
This is called the nail matrix.
The living cells that cause a nail to grow are found in the?
i belive it is the nail root.
How do toenails and fingernails grow?
Nails grow from an area of rapidly dividing cells known as the nail root. The nail root is located at the tips of fingers and toes. During cell division, the cells of the nail root fill with keratin and produce a tough, platelike nail that covers and protects the tips of fingers and toes.
What tissue gives rise to a plant root's hair and a human root hair?
In plants, root hairs originate from the epidermal cells of the root tissue, specifically from specialized root epidermal cells called trichoblasts. In humans, hair follicles in the skin produce root hairs, which are composed of keratinized cells that grow from the hair follicle.
Why are nails growing?
The Nail Grows From The Nail Root And Then The Dead Nail Get's Pushed Up And They Grow. But What You Can See On Your Nail Is DEAD ! Hope i helped.
Where does nail production occur?
It occurs at the end of your nail, closest to the knuckle. As you age, the nails grow outward, adding more and more dead cells. The area specifically associated with nail production is called the root of the nail. There are six parts of the nail wherein the root is were this event mostly takes place. http://dermatology.about.com/cs/nailanatomy/a/nailanatomy.htm Check this site out if you want to know more about the nail.
What are the nails in the human body made of?
Human nails are made of hard keratinized cells; keratin being a type of protein.
Can nail polish cause white spots on nails?
No the white spots on the nail is from damage to the matrix this is the root of the nail and it will grow out of the nail but it may take some time.
Are fingernails made of dead skin?
Just like hair, your nails are protein deposits that grow as needed. They have no blood cells or veins to feed them, so they are not living.
Parrots claw fell off will it grow back?
It depends, if the root has been removed, no, if not then yes it can grow back, the same as a human nail.
Do cells at plants roots divide quickly to form new cells?
yes it's true because roots grow longer because of a special tissue near the root tips.Here,cells divide quickly to form new cells.
What does the nail body cover?
nail root
