The correct Answer is:
To solve the question, we need to analyze the features provided and determine which type of plant tissue they describe. The options given are chlorenchyma, parenchyma, xylem, and sclerenchyma. Let's break down each feature step by step: ### Step 1: Analyze Feature I **Feature I:** Cells are thick at corners due to the deposition of cellulose, hemicelluloses, and pectin. - **Analysis:** This feature indicates that the cells have thickened corners, which is characteristic of certain types of plant tissues. In this case, it aligns with chlorenchyma, which is known for having thickened cell walls due to the deposition of these materials. ### Step 2: Analyze Feature II **Feature II:** Cells may contain chloroplasts and get assimilated. - **Analysis:** Chlorenchyma is a type of parenchyma that contains chloroplasts, allowing it to perform photosynthesis. This feature supports the idea that we are dealing with chlorenchyma. ### Step 3: Analyze Feature III **Feature III:** Intercellular spaces are absent. - **Analysis:** The absence of intercellular spaces suggests that the cells are tightly packed. This is also a characteristic of chlorenchyma, where cells are closely arranged to maximize light absorption for photosynthesis. ### Step 4: Analyze Feature IV **Feature IV:** Provide mechanical support to growing parts of the plant such as young stem and petiole of the leaf. - **Analysis:** While chlorenchyma has some mechanical support functions, this feature is more indicative of sclerenchyma, which is known for providing structural support. However, since the previous features strongly point towards chlorenchyma, we must consider that chlorenchyma can also contribute to the support of young plant parts. ### Conclusion After analyzing all the features, it is clear that they collectively describe **chlorenchyma**. ### Final Answer The features describe **chlorenchyma**. ---
