B. unable to make food but could obtain usable energy from the environment.
C. able to make food and it would have the usable energy to survive.
D. unable to make food and without food for energy it would die.
Constructed Response L.8.B.1
1. Cells have a variety of organelles, each with a specific function. The organelles must
work together in order for the cell to survive.
a. Describe the function of a chloroplast and mitochondria. Include a basic
description of the chemical reaction that takes place in each organelle.
b. Describe how the chloroplast and mitochondria work together to help a plant cell
survive.
c. Predict what would happen if a plant cell lacked mitochondria. Justify your
answer.

Constructed Response L.8.B.1 Score Rubric:
Response addresses all parts of the question clearly and
correctly.
3 points
A. The chloroplast is the site of photosynthesis where sunlight
energy, carbon dioxide and water are converted to simple
sugars (food). The mitochondria is the site of cellular
respiration where glucose is broken down into usable cellular
energy.
B. A plant cell contains both chloroplasts and mitochondria.
Food (simple sugars) is made in the chloroplast. The sugars
are stored until the cell needs energy. The sugars are then
transferred to the mitochondria to be broken down into usable
energy (ATP?) to carry out cellular activities.
C. A plant cell that lacked mitochondria would be able to make
food but would be unable to convert the food into cellular
energy. The cell would die.
