Study Notes
Nitrogen Fixation
- Nitrogen fixation takes place in a specialized structure in legume roots called nodules.
Plant Cells
- Oxygen is the most abundant element in plant cells.
Plant Water Regulation
- Plants maintain their water content despite constant water loss through a process called osmoregulation.
Cnidarians and Flatworms
- Cnidarians and flatworms have a digestive tract with only one opening, called a gastrovascular cavity.
Dermal Tissue System
- The main function of the dermal tissue system in plants is to protect the plant from injury, infection, and water loss.
Diet
- Omnivory is a type of diet that involves consuming both plant-based and meat-based foods.
Human Respiratory System
- Gas exchange occurs in the alveoli of the human respiratory system.
Blood Function
- The function of hemoglobin in the blood is to transport oxygen from the lungs to the body's tissues.
Circulatory System
- Insects, mollusks, and some other invertebrates have an open circulatory system.
Xylem Sap
- The function of xylem sap in plants is to transport water and minerals from the roots to the rest of the plant.
Connective Tissue
- The role of connective tissue in organisms is to provide support, structure, and connectivity to the body.
Plant Transport
- Plants move food, water, and minerals around using a system called the vascular tissue system, which is comprised of xylem and phloem.
