15 Questions
What makes xylem and phloem complex tissues?
They are made of more than one type of cells that coordinate to perform a common function.
What is the main function of xylem in plants?
Transporting water and minerals vertically from soil to aerial parts of the plant.
What is the primary role of phloem in plants?
Transporting food from leaves to other parts of the plant and from storage parts to other parts.
Name two components of xylem and two components of phloem.
Xylem: Tracheids, vessels; Phloem: Sieve tubes, companion cells
Differentiate between xylem fibers and phloem fibers.
Xylem fibers are part of xylem and provide mechanical support, while phloem fibers are part of phloem and are involved in food transport.
Explain why xylem and phloem are considered complex tissues.
Xylem and phloem are considered complex tissues because they are made up of multiple cell types that work together to perform a specific function.
What is the main function of xylem in plants?
Xylem transports water and minerals vertically from the soil to the aerial parts of the plant.
Describe the composition of xylem and phloem in terms of cell types.
Xylem consists of tracheids, vessels, xylem parenchyma, and xylem fibers, while phloem consists of sieve tubes, companion cells, phloem parenchyma, and phloem fibers.
What is the role of phloem in plants?
Phloem transports food from leaves to other parts of the plant and from storage parts to other areas.
Differentiate between xylem fibers and phloem fibers.
Xylem fibers provide mechanical support and are dead cells, while phloem fibers are living cells that provide structural support.
Why do xylem and phloem contain different types of cells?
Xylem and phloem contain different types of cells to perform specialized functions efficiently.
Explain how xylem transports water and minerals in plants.
Xylem transports water and minerals vertically through the plant, from roots to leaves, using specialized cells like tracheids and vessels.
What is the significance of companion cells in phloem?
Companion cells in phloem play a vital role in assisting sieve tubes with various functions, such as loading and unloading of nutrients.
How do the components of phloem work together to transport food in plants?
The sieve tubes in phloem carry food substances, while companion cells assist in maintaining the metabolic functions required for nutrient transport.
Discuss the importance of xylem and phloem in the overall functioning of plants.
Xylem and phloem are crucial for the transport of essential substances like water, minerals, and food, which are necessary for plant growth, development, and survival.
