Question 1

This image shows an endoplasmic reticulum in an animal cell. Which of the following statements about this organelle is true?
- The endoplasmic reticulum is also found in plant cells
- The endoplasmic reticulum is not found in plant cells
- The endoplasmic reticulum is part of the process of photosynthesis
- The endoplasmic reticulum is not important to the function of an animal cell
Explanation: The answer is "The endoplasmic reticulum is also found in plant cells."
Plants and animals are both organisms, meaning that like other living things, they are composed of cells. Both types of cells store food in vacuoles, have cytoplasm, golgi bodies, and ribosomes, but they have a number of distinct differences as well. Animal cells have a membrane and are more irregularly shaped, while plant cells have a cell wall and are rectangular. Additionally, plant cells have organelles called chloroplasts, which aid in the process of photosynthesis.
