What is the importance of guard cells ?

Biology
1 answer:
WITCHER [35]3 years ago
5 0

The guard cell is responsible for controlling the size of the stomata in leaves. These do so as a result of an interaction between potassium ions and water in and around the cells. When potassium ions accumulate inside the guard cells the water potential inside these cells is lower than that of the outside and as a result, water has to be taken in. This makes the guard cells turgid which in turn stretches them and results in the opening of the stomata. Meanwhile, when potassium ions accumulate outside the cell, the opposite scenario results. Water from inside the cell moves out, making the guard cells flaccid, thus causing these to cover (and effectively close) the stomata.

Answer:

es bastante raro pero sucede que depende de los genes

ESPANOL -

El albinismo es una condición genética en la que las personas nacen sin el pigmento (color) habitual en sus cuerpos. Sus cuerpos no pueden producir una cantidad normal de melanina, el químico responsable del color de los ojos, la piel y el cabello. Entonces, la mayoría de las personas con albinismo tienen piel, cabello y ojos muy pálidos. El albinismo puede afectar a personas de todas las razas, y existen diferentes tipos de albinismo.

Algunas personas con una afección llamada albinismo oculocutáneo tienen piel y ojos extremadamente pálidos y cabello blanco. Otros con este mismo tipo de albinismo pueden tener un poco más de color en el cabello, los ojos o la piel.

Para algunas personas, el albinismo afecta solo sus ojos. Esto se conoce como albinismo ocular. Las personas con albinismo ocular generalmente tienen ojos azules. En algunos casos, el iris (la parte coloreada del ojo) tiene muy poco color, por lo que los ojos de una persona pueden verse rosados ​​o rojizos. Esto es causado por los vasos sanguíneos dentro del ojo que se muestran a través del iris. En algunas formas de albinismo ocular, la audición de los nervios auditivos puede verse afectada y la persona puede desarrollar problemas de audición o sordera con el tiempo.

Excepto por los problemas oculares, la mayoría de las personas con albinismo son tan saludables como cualquier otra persona. En casos muy raros, el albinismo de una persona es parte de otra afección que involucra otros problemas de salud además del albinismo. Las personas con este tipo de albinismo pueden tener complicaciones de salud tales como problemas de sangrado, pulmón, intestino y sistema inmunológico.

it's pretty rare but it happens it depends on the genes

ENGLISH - Albinism is a genetic condition where people are born without the usual pigment (color) in their bodies. Their bodies aren't able to make a normal amount of melanin, the chemical that is responsible for eye, skin, and hair color. So most people with albinism have very pale skin, hair, and eyes. Albinism can affect people of all races, and there are different kinds of albinism.

Some people with a condition called oculocutaneous albinism have extremely pale skin and eyes, and white hair. Others with this same type of albinism might have slightly more color in their hair, eyes, or skin.

For some people, albinism affects only their eyes. This is known as ocular albinism. People with ocular albinism usually have blue eyes. In some cases, the iris (the colored part of the eye) has very little color so a person's eyes might look pink or reddish. This is caused by the blood vessels inside the eye showing through the iris. In some forms of ocular albinism, the hearing nerves hearing may be affected and the person may develop hearing problems or deafness over time.

Except for eye problems, most people with albinism are just as healthy as anyone else. In very rare cases a person's albinism is part of another condition that involves other health problems in addition to albinism. People with these types of albinism can have such health complications as bleeding, lung, bowel, and immune system problems.
