Answer:
1. C
2. B
Explanation:
1. When a plant cell looses some water due to dehydration or being placed in a hypertonic solution, the term used to describe the cell's intial, not severe shrinkage is 'flaccid'.
Here, it's clear that the cell shrank so much that the cell membrane pulled away from the cell wall. The correct term for this severe shrinkage is 'plasmolysed'.
We don't use 'wilted' as a term to describe a cell. We use it to describe the plant as a whole.
2. This is the function of each. Water and ions in xylem and sugars like sucrose in phloem.

Answer: the answer is option A. 5 → 1 → 6 → 3 → 2 → 4
Explanation: the events that describe progress of a protein that will be secreted from cell are as follows; Protein synthesis begins in the cytosol, SRP binds to the growing polypeptide chain and to the ribosome, Translation pauses, SRP binds to its receptor, Translation resumes and finally - The signal sequence is cleaved. All these formed the sequence 5 → 1 → 6 → 3 → 2 → 4
