Question

1. proteins are one of the substances produced by cells. which organelle is responsible for storing the genetic information responsible for the production of proteins?

a nucleus
b lysosome
c golgi apparatus
d endoplasmic reticulum

1. how would cellular homeostasis be immediately affected if the cell did not have golgi bodies?

a lysosomes would not be able to break down wastes, as there would be no products being produced by the cell.
b vacuoles would not have material to store because water and other materials would not be able to enter the cell.
c proteins would not be able to be made because the ribosomes would not have the instructions they need to produce them.
d organelles would not receive the products they need to function and materials that were made within the cell would not be able to leave the cell for use.

1. all living organisms break down sugar to obtain energy using cellular respiration. which of the following chemical reactions represents the process of aerobic cellular respiration?

a oxygen + water → glucose + lactose
b glucose + lactose → oxygen + water
c water + carbon dioxide + energy → oxygen + glucose
d oxygen + glucose → water + carbon dioxide + energy

1. which of the following best explains how the cell theory was developed?

a cells are so diverse that scientists had to come up with an explanation that would apply to all types of cells.
b mutations occur and cause changes in cells, so scientists could not develop a law that would apply to all forms of cells.
c the cell theory is a well - tested explanation of observations that was formed from the contributions of several different scientists.
d the cell theory was developed through extensive library research, because it would be impossible to test all living things for the presence of cells.

Explanation:

• Question 16: The nucleus contains DNA which stores genetic information for protein production. Lysosomes break down waste. Golgi apparatus modifies and sorts proteins. Endoplasmic reticulum is involved in protein synthesis but not storing genetic info.
• Question 17: Golgi bodies modify, package and distribute proteins and lipids. Without them, organelles won't get needed products and cell - made materials can't leave. Lysosomes' function (A) is not directly related to Golgi. Vacuoles (B) and ribosome - protein synthesis (C) are not about Golgi's main role.
• Question 18: Aerobic cellular respiration uses oxygen and glucose to produce water, carbon dioxide and energy. Option A and B have wrong reactants/products. Option C is like photosynthesis in reverse.
• Question 19: Cell theory is a well - tested explanation from multiple scientists' contributions (e.g., Schleiden, Schwann, Virchow). Option A is not the reason for development. Option B is about mutations not theory development. Option D is incorrect as it was based on observations not just library research.

Answer:

1. A. nucleus
2. D. Organelles would not receive the products they need to function and materials that were made within the cell would not be able to leave the cell for use.
3. D. oxygen + glucose → water + carbon dioxide + energy
4. C. The cell theory is a well - tested explanation of observations that was formed from the contributions of several different scientists.
