Which of the following is correctly matched with its tissue system?
cortex/dermal tissue system
cuticle/vascular tissue system
phloem/dermal tissue system
stele/vascular tissue system>>>> my choosen answer
agree
D. Stele/vascular tissue
Your chosen answer is correct. The tissue system that is correctly matched with "stele" is the vascular tissue system. The stele refers to the central cylinder of tissues in a plant root, stem, or leaf, which includes the vascular tissues responsible for water and nutrient transportation.
To determine which of the following is correctly matched with its tissue system, we need to understand the different tissue systems found in plants and their corresponding components.
The three tissue systems in plants are:
1. Dermal Tissue System: This system comprises the outer protective covering of the plant and includes the epidermis, cuticle, and periderm (in older stems and roots).
2. Vascular Tissue System: This system is responsible for transporting water, nutrients, hormones, and other substances throughout the plant. It includes xylem, which transports water and minerals upward, and phloem, which transports sugars and other organic molecules both upward and downward.
3. Ground Tissue System: This system makes up the bulk of the plant and performs various functions, such as photosynthesis, storage, and support.
Now, let's examine the given options:
a. cortex/dermal tissue system: The cortex is a component of the ground tissue system and is not part of the dermal tissue system. Incorrect match.
b. cuticle/vascular tissue system: The cuticle is a waxy layer present on the outer surface of the epidermis, which belongs to the dermal tissue system. It is not part of the vascular tissue system. Incorrect match.
c. phloem/dermal tissue system: The phloem is a part of the vascular tissue system responsible for the transport of sugars. It does not belong to the dermal tissue system. Incorrect match.
d. stele/vascular tissue system: The stele is the central region of the stem or root that includes the vascular tissue system (xylem and phloem). This is the correct match.
Therefore, the correct answer is: stele/vascular tissue system.
