Plant's Moving Materials
his process allows water molecules to move through plant tissues from areas of high concentration to areas of low concentration.
What is osmosis?
This is the main organ of the respiratory system in humans, where gas exchange occurs.
What are the lungs?
These microscopic sacs at the ends of bronchioles are where gas exchange occurs.
What are alveoli?
The heart, blood, and blood vessels together make up this system.
What is the circulatory system?
Animals such as fish use these structures to take in oxygen from water.
What are the gills?
This type of vascular tissue transports water and dissolved nutrients from the roots to the stem and leaves.
What is xylem?
These narrow tubes branch from the trachea and lead into the lungs.
What are bronchi?
During gas exchange, this gas moves into the blood while carbon dioxide moves into the alveoli.
What is oxygen?
These vessels carry blood away from the heart.
What are arteries?
The trachea is also known by this name because it connects the throat to the bronchi.
What is the windpipe?
This vascular tissue carries dissolved sugars throughout the plant.
What is phloem?
This system is responsible for transporting oxygen, nutrients, and waste materials throughout the human body using the heart, blood vessels, and blood.
What is the circulatory system?
These blood cells drop off carbon dioxide and pick up oxygen during gas exchange.
What are red blood cells?
These vessels carry blood back to the heart.
What are veins?
The main muscle involved in breathing, which contracts and relaxes to move air in and out of the lungs.
What is the diaphragm?
These small openings on the surface of leaves are controlled by guard cells and allow gas exchange.
What are stomata?
This tube, held open by C-shaped rings of cartilage, connects the pharynx to the bronchi and is commonly called the windpipe.
What is the trachea?
Animals with three or four-chambered hearts, like amphibians, generally have these for gas exchange.
What are lungs?
The two upper chambers of the heart are called this
What are atria?
This part of the respiratory system is shared by both the digestive and respiratory systems.
What is the pharynx?
Name one plant that moves materials primarily through osmosis and diffusion.
What is moss?
These very tiny blood vessels enable the exchange of oxygen, carbon dioxide, and nutrients between the circulatory system and body tissues.
What are capillaries?
The walls of alveoli are this many cells thick, allowing efficient gas exchange.
What is one?
Blood vessels in the lungs that transport oxygen-rich blood to the heart are called this.
What are pulmonary veins?
These hose-like structures in insects branch into smaller tubes, allowing oxygen to diffuse directly to cells and carbon dioxide to diffuse out, bypassing the need for a circulatory system to transport gases.
What are tracheal tubes?
