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.
In a plant cell what organelle opens and closes?
They are called guard cells. They control how much carbon dioxide and water is entering the plant.
How does oxygen and carbon dioxide enter and leave the cell?
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 goes into a plant through its stomata?
stoma (also stomate; plural stomata) is a tiny opening or pore, found mostly on the underside of a plant leaf and used for gas exchange. Air containing carbon dioxide enters the plant through these openings where it is used in photosynthesis and respiration. Oxygen produced by photosynthesis in the spongy layer cells (parenchyma cells with pectin) of the leaf interior exits through these same openings. Also, water vapor is released into the atmosphere through these pores in a process called transpiration.
what two substances enter and leave the leaf in photosynthesis?
The leaf first takes in Carbon Dioxide, or CO2, into it's self through the bottom of the leaf. It uses the CO2 and makes sugars out of it, water, and sunlight. This reaction makes a byproduct, Oxygen, that the leaf lets out, which we use to breathe.
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.
Where do carbon dioxide and oxygen from the air enter and leave and leaf?
guard cells and stomata.
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
What principles govern whether oxygen or carbon dioxide to enter and leave the blood in the lungs and in the tissue?
Diffusion
Name gases e and f which enter and leave the lungs?
Oxygen (O2) and Carbon Dioxide (CO2) =)
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.
Describe several ways gases enter and leave the atmosphere.?
plants take in carbon dioxide and release oxygen
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.
What are guard cells and what is their function?
Guard cells allows the exchange of oxygen and carbon dioxide in and out of the leaf. This is known as leaf exchange. When guard cells are full of water they swell up and close meaning no oxygen can leave or carbon dioxide can enter, but when the water is taken away from the cell they open up to allow oxygen to exit and carbon dioxide to enter.
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
