Welcome all to a test on the scientific study of biology, where we will have our microscopes focused in on a particularly important topic – the cell! In this review test for students at an eighth-grade level, we aim to test your knowledge on the cell, its functions, structure and more!

Questions and Answers

1.

All living things on earth are made up of
- A.
  
  Organs
- B.
  
  Eggs
- C.
  
  Cells
- D.
  
  Food
- E.
  
  Organelles
Correct Answer
C. Cells

Explanation
Living things on Earth are made up of cells. Cells are the basic building blocks of life and are responsible for the structure and function of all living organisms. They are the smallest unit of life and can perform all the necessary functions for an organism to survive and reproduce. Cells can be found in all living organisms, from single-celled bacteria to complex multicellular organisms like plants and animals. Without cells, life as we know it would not exist.

The largest known cells are ____ cells:
- A.
  
  Tissue
- B.
  
  Egg
- C.
  
  Food
- D.
  
  Nucleus
Correct Answer
B. Egg

Explanation
The largest known cells are egg cells. Egg cells, also known as ova or oocytes, are the reproductive cells produced by females in many organisms, including humans. These cells are significantly larger compared to other types of cells in the body due to their role in supporting the development of a new organism. The large size of egg cells allows for the storage of nutrients and genetic material necessary for fertilization and early embryonic development.

Photosynthesis is the basis of all the world's ____ and _____
- A.
  
  Water and food
- B.
  
  Water and oxygen
- C.
  
  Food and oxygen
- D.
  
  Protein and food
- E.
  
  Oxygen and protien
Correct Answer
C. Food and oxygen

Explanation
Photosynthesis is the process by which plants convert sunlight into energy, utilizing water and carbon dioxide. This energy is used to produce food in the form of glucose, which is then stored in the plant's cells. Additionally, as a byproduct of photosynthesis, oxygen is released into the atmosphere. Therefore, the correct answer is "food and oxygen" as photosynthesis is responsible for the production of both.

_____ bodies package proteins to be shipped to other parts of the cell or even outside of the cell.
- A.
  
  Golgi
- B.
  
  Membrane
- C.
  
  Human
- D.
  
  Lysosome
Correct Answer
A. Golgi

Explanation
The Golgi bodies play a crucial role in packaging proteins to be transported to other parts of the cell or even outside of the cell. They receive proteins from the endoplasmic reticulum and modify them by adding various molecules to them. These modified proteins are then sorted, packaged into vesicles, and transported to their final destination within the cell or secreted outside of the cell. Therefore, the Golgi bodies are responsible for the proper sorting and packaging of proteins for intracellular and extracellular transport.
