By passive diffusion down its concentration gradient, which requires no energy expenditure from the cell. Basically, if you have more oxygen outside a cell than inside a cell, it travels through channels or holes in the cell membrane until the concentration of oxygen is equal inside and outside the cell.
What else can I help you with?
How does carbon dioxide and oxygen enter and leave the leaf?
stomata
State two substances that pass into the blood?
Two substances that pass into the blood include oxygen and carbon dioxide. The blood carries fresh oxygen to the cells and tissues and removes waste materials.
What goes into a plant through its stomata?
Carbon dioxide and water vapor enter a plant through its stomata. These gases are essential for photosynthesis to occur, with carbon dioxide being used to produce sugars and oxygen being released as a byproduct.
How air body enter and leave the body?
Air enters the body through the respiratory system by inhaling air through the nose or mouth. The air then travels down the trachea into the lungs, where oxygen is absorbed into the bloodstream and carbon dioxide is released. When exhaling, the carbon dioxide is expelled from the lungs back out through the nose or mouth.
How do substances for photosynthesis enter and leave the plant?
The gas for photosynthesis...carbon dioxide diffuses into the plant through its stomata ('holes' in the leaf's underside). Water is transported through the plant in the xylem tube (waterproof tube that makes up part of the plants veins and covers the whole plants structure) as it is drawn up from the roots where it is absorbed. It is drawn up by the water evaporationg through the stomata. The light obviously enters the leaf and enters the chloroplasts where it combines with the chlorophyll to provide the energy for the photosynthesis reaction. The products from photosynthesis...glucose and oxygen are removed from the plant leaves. Glucose through the phloem tube (another of the veins) and oxygen through diffusion through the stomata or it is used up in respiration.
Where does the oxygen enters and carbon dioxide leaves?
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
What are the two gases that enter and leave the lungs?
There are a number of gases that enter and leave the lungs - predominantly, humans Inspire (Breathe in) Oxygen and Expire (Breathe out) Carbon Dioxide. soo that is the answer init lool x
Name gases e and f which enter and leave the lungs?
Oxygen (O2) and Carbon Dioxide (CO2) =)
What principles govern whether oxygen or carbon dioxide to enter and leave the blood in the lungs and in the tissue?
Diffusion
Where does oxygen enter the blood and carbon dioxide leave the blood?
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
What organ does the oxygen-carbon Dioxide take place?
Oxygen is brought into the blood, and carbon dioxide released from the blood, at the alveoli of the lungs. Gases diffuse across the alveolar membrane to enter or leave the blood.
Where do carbon dioxide and oxygen from the air entre and leave the leaf?
Carbon dioxide and oxygen enter and leave the plant through the stomata, on the underside of leaves.
What causes oxygen to enter and carbon dioxide to leave the capillaries?
Oxygen and carbon dioxide get into and out of cells via diffusion. The gases diffuse across the thin capillary wall, and then diffuse across the cell membrane.
Why both oxygen and carbon dioxide enter and leave the plant?
Oxygen and carbon dioxide both enter and leave the plant through small openings called stomata, which are primarily located on the underside of leaves. During photosynthesis, plants take in carbon dioxide from the atmosphere and release oxygen as a byproduct. Conversely, during respiration, plants consume oxygen to break down glucose for energy, producing carbon dioxide. This exchange is vital for maintaining the balance of gases in the atmosphere and supporting the plant's metabolic processes.
Where do carbon dioxide and oxygen from the air enter and leave and leaf?
Carbon dioxide enters through small pores called stomata on the underside of the leaf. Oxygen is released through the same stomata during photosynthesis.
How oxygen and carbon dioxide enter and leave cells?
carbon dioxide goes into pores in the under surface of the leaf, called stomata, and diffuse into the leafs tissues and oxygen exits through these pores aswell though this cannot happen when the stomata close up
How does oxygen leave the plant and carbon dioxide enter a plant?
Oxygen leaves the plant through small pores on the leaves called stomata during the process of transpiration. Carbon dioxide enters the plant through the same stomata during photosynthesis, where it is converted into glucose for energy.
