The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Assertion**: The assertion states that downstream processing is generally considered more difficult and costlier in plants than in microbes. This is true because plants typically yield less biomass of the target proteins compared to microbes, making the purification process more challenging and expensive. 2. **Understanding the Reason**: The reason provided is that rhizosecretion is used as a method to facilitate easier recovery of recombinant proteins from plants. This statement is also true. Rhizosecretion involves engineering plants to secrete proteins through their roots, which can simplify the recovery process. 3. **Evaluating the Relationship**: While both the assertion and the reason are true, the reason does not provide a correct explanation for the assertion. The assertion discusses the general difficulty and cost of downstream processing in plants due to low biomass, while the reason focuses on a specific method (rhizosecretion) that may help in recovery but does not address the overall cost or difficulty compared to microbes. 4. **Selecting the Correct Option**: Based on the evaluation, the correct option is that both the assertion and reason are true, but the reason is not the correct explanation for the assertion. This aligns with option B. ### Final Answer: The correct answer is option B: Both assertion and reason are true, but reason is not the correct explanation for assertion. ---

Which of the following methods is/are used in recovery of healthy plants from diseased plants ?

Assertion: C_(4) photosynthetic pathway is more efficient than the C_(3) pathway. Reason : Photorespiration is suppressed in C_(4) plants.

Assertion :- DNA finger printing is a unique process through which recombinants are identified similar to mother parent. Reason: Micropropagation is a technique to produce genetically uniform plants.

Assertion : Secondary metabolites are produced in small quantities and their extraction from the plant is difficult and expensive. Reason : Secondary metabolites can be commercially produced by using tissue culture techinque.

Assertion :- Taxonomic keys are generally not analytical in nature. Reason :- From couplets one characters is accepted and other is rejected, this rejected character is present in other plants.

Assertion: Presence of photorespiration is considered as a wasteful and energy consuming process in crop plants, ultimately leads to reduction in yield. Reason: During C_(3) synthesis upto 50% CO_(2) fixed may have to pass through photorespiratory process to form carbohydrate such as sucrose.

Assertion : Photorespiration is a useful process where there is no synthesis of ATP energy. Reason : RuBisCO is present in mesophyll cells of C_(4) plants, hence they show more productivity.

Assertion:- Boric acid cannot be titrated with NaOH solution. Reason:- Cupellation is the process used to remove silver impurity from Pb. Reason:- This method is used when metal is easily oxidised by air but oxidation of impurity is not possible.

Read the assertion and reason carefully to mark the correct option out of the option given below: Assertion: Carbohydrates are more suitable for the production of energy in the body than proteins and fats. Reason : Carbohydrates can be stored in the tissues as glycogen for use in the production of energy, whenever necessary. If both assertion and reason are true and reason is the correct explanation of assertion. If both assertion and reason are true but reason is not the correct explanation of assertion. If assertion is true but reason is false. If both assertion and reason are false.

Assertion : An electrostatic precipitator (ESP) is a particulate collection device that removes dust and smoke particles from flowing air using the force of an induced electrostatic charge. Reason : An ESP is a highly efficient device as it removes 99 percent of particulate matter present in the exhaust from a thermal power plant.
