Question
a plant cell shows the structures that are likely to be observed in a typical plant cell Cells from from the model are specialized for specific How could this model be changed to best repre- sent a specialized leaf cell? A. Remove the cell wall because only cells in plant stems have cell walls. B. Remove the mitochondria because leaf cells don't need much energy. C. Add tiny hairs because leaf cells need to take in water. D. Add chloroplasts because leaves are where photosynthesis occurs. E.

Answer
D. Add chloroplasts because leaves are where photosynthesis occurs.
Explanation
To answer this question, we need to consider the functions of a specialized leaf cell in a plant. Leaf cells are primarily involved in photosynthesis, the process by which plants convert light energy into chemical energy. Let's evaluate the options:A. Remove the cell wall because only cells in plant stems have cell walls.This statement is incorrect. All plant cells, including those in leaves, stems, and roots, have cell walls. The cell wall provides structure and support to the cell.B. Remove the mitochondria because leaf cells don't need much energy.This statement is incorrect. While leaf cells do perform photosynthesis, they also require energy for other cellular processes. Mitochondria are present in leaf cells to provide this energy.C. Add tiny hairs because leaf cells need to take in water.While some leaves may have tiny hairs (trichomes) that can help with water absorption and other functions, this is not a universal characteristic of all leaf cells and is not directly related to the primary function of photosynthesis.D. Add chloroplasts because leaves are where photosynthesis occurs.This statement is correct. Chloroplasts are the organelles where photosynthesis takes place, and they are abundant in leaf cells, which are the primary sites of photosynthesis in plants.E. Remove the cell membrane because a leaf cell has a cell wall instead of a cell membrane.This statement is incorrect. Plant cells, including leaf cells, have both a cell wall and a cell membrane. The cell membrane controls the movement of substances in and out of the cell, while the cell wall provides additional support and structure.
