Massachusetts Comprehensive Assessment System

2016, High School Biology

  Question 32: Open-Response  
The diagram below represents a plant cell with three structures labeled X, Y, and Z.
The cell is square shaped with rounded corners. The outermost part of the cell is labeled X. The next layer around the cell is labeled Y. Inside the cell are many different structures. There are many small dots in the cell. There is one large membrane bound structure that makes up almost half of the cell area and is white inside. The structure labeled Z has a membrane around several small discs connected to each other.  There are several of these structures inside the plant cell.
Plant cells and fungal cells have many of the same types of organelles. Structures X and Y are found in both plant cells and fungal cells. Structure Z is found in plant cells, but not in fungal cells.
  1. Identify structure Y and describe its main function.
     
  2. Identify structure Z and explain how plants use this structure to survive.
     
  3. Explain how fungi can survive without structure Z.

Scoring Guide and Sample Student Work
Select a score point in the table below to view the sample student response.

ScoreDescription
4 The response demonstrates a thorough understanding of cell parts and how cellular evidence is used to describe modes of nutrition in different kingdoms. The response correctly identifies structure Y and clearly describes its main function. The response also correctly identifies structure Z and clearly explains how plants use this structure to survive. The response clearly explains how fungi can survive without structure Z.
4
3 The response demonstrates a general understanding of cell parts and how cellular evidence is used to describe modes of nutrition in different kingdoms.
2 The response demonstrates a limited understanding of cell parts and how cellular evidence is used to describe modes of nutrition in different kingdoms.
1 The response demonstrates a minimal understanding of cell parts and how cellular evidence is used to describe modes of nutrition in different kingdoms.
0 The response is incorrect or contains some correct work that is irrelevant to the skill or concept being measured.

Note: There are 2 sample student responses for Score Point 4.
