Which of these components of the phloem has its cytoplasm pushed to the sides while also lacking nucleus?
- A) Companion cell,
- B) Sieve tube elements
- C) Sieve plate
- 6
Correct Answer: B) Sieve tube elements
Explanation
The question is asking which component of the phloem lacks a nucleus and has its cytoplasm pushed to the sides. The options are Companion cell, Sieve tube elements, Sieve plate, and Parenchyma, and we are to choose the correct answer. The phloem is a type of plant tissue that transports sugars and nutrients from the leaves to other parts of the plant. It consists of different components including the companion cell, sieve tube elements, sieve plate, and parenchyma. Out of the four options given, the component of the phloem that has its cytoplasm pushed to the sides and lacks a nucleus is the sieve tube elements. The sieve tube elements are long, tube-like structures that form a continuous channel for transport of sugars and nutrients. They are closely associated with the companion cells, which support their metabolic functions. In summary, the correct answer to the question is Option B: Sieve tube elements. They have their cytoplasm pushed to the sides and lack a nucleus. It is important for Biology students to understand the different components of the phloem and their functions in plant transportation.
