The question asks: "Which of the following statements is NOT true of the piliferous layer of root?"
The website indicates Option A as the correct answer, stating that the piliferous layer does not have a very thin cuticle.
This is incorrect. In reality, the piliferous layer (root epidermis) does possess a very thin cuticle — or sometimes none at all — to facilitate water and mineral absorption.
The statement that is not true is Option B: "Is the outermost layer of the cortex." The piliferous layer is the epidermis, which lies outside the cortex, not part of it.
Therefore, the correct answer should be B, not A. Please review and correct this error.
Thank you.
please make correction...The correct answer is A.the piliferous layer has no cuticle.
The statement that is NOT true of the piliferous layer of the root is:
E. Is replaced by cork in old roots.
Explanation:
A. Has a very thin cuticle: This is true. The piliferous layer, which consists of the outermost layer of the root epidermis, has a very thin or even absent cuticle to facilitate the absorption of water and nutrients.
B. Is the outermost layer of the cortex: This is true. The piliferous layer is indeed the outermost layer of the root, located just beneath the root cap, and it forms the epidermis of the root.
C. May bear root hairs: This is true. The piliferous layer is where root hairs are found, which increase the surface area for absorption of water and nutrients.
D. Breaks down as the root ages: This is true. As the root matures, the piliferous layer may degenerate or slough off to make way for the formation of a protective outer layer, such as the cork in older roots.
E. Is replaced by cork in old roots: This is NOT true. While the piliferous layer does break down with age, it is not replaced by cork. The cork replaces the epidermis in older parts of the root, but the piliferous layer, specifically, does not get replaced by cork. The cork comes from a different tissue, the periderm, which is formed by the cork cambium.
So, the correct answer is E.
The root of a plant doesn't have cuticle is the only place Dat lack cuticles, reason bcos is use for water absorption
B is correct as proliferous layer isn't the outermost part of the cortex. it's simply the outermost part of the epidemis
B is the correct answer this is how you guys fail people with correct answer in jamb. God will protect us 😞
The correct answer is **B. Is the outermost layer of the cortex**.
This statement is **NOT true** because the piliferous layer is the outermost layer of the root (epidermis), not the cortex. The cortex is internal to the piliferous layer, and its outermost layer is the **endodermis**, not the piliferous layer.
