SCI06 Life Science Test 1

Questions and Answers

1.

Which of the follow is considered nonliving?
- A.
  
  Water
- B.
  
  Grass
- C.
  
  Bacteria
- D.
  
  Wood
- E.
  
  Ants
Correct Answer
A. Water

Explanation
Water is considered nonliving because it does not possess the characteristics of living organisms. It does not have cells, does not grow, does not reproduce, and does not respond to stimuli. Water is a compound made up of hydrogen and oxygen atoms, and it exists in three states - solid (ice), liquid (water), and gas (water vapor). While it is essential for the survival of living organisms, water itself is not alive.

What type of cell is this?
- A.
  
  Animal
- B.
  
  Plant
- C.
  
  Human
- D.
  
  Dog
- E.
  
  Worm
Correct Answer
B. Plant

Explanation
This cell is a plant cell because plants have unique cellular structures such as a cell wall, chloroplasts for photosynthesis, and large central vacuoles. These features are not present in animal, human, dog, or worm cells.

The arrow is pointing to the dot that represents what part of the cell?
- A.
  
  Chloroplast
- B.
  
  Endoplasmic Reticulum
- C.
  
  Lysosome
- D.
  
  Mitochondria
- E.
  
  Ribosome
Correct Answer
D. Mitochondria

Explanation
The arrow is pointing to the dot that represents the mitochondria. Mitochondria are known as the powerhouses of the cell, responsible for producing energy in the form of ATP through cellular respiration. They have a distinct shape and are often depicted as small, dot-like structures within the cell.

What is the FUNCTION of the part pointed to below? In other words, what does it do?
- A.
  
  Supports the structure of the cell
- B.
  
  Provides energy for the cell
- C.
  
  Produces food for the cell
- D.
  
  Controls what goes in and out of the cell
- E.
  
  Gives the cell instructions
Correct Answer
B. Provides energy for the cell

Explanation
The part pointed to in the question is responsible for providing energy for the cell. It is not involved in supporting the structure of the cell, producing food for the cell, controlling what goes in and out of the cell, or giving the cell instructions. Its main function is to generate energy that the cell needs to carry out its various processes and functions.

The arrow is pointing to the dot that represents what part of the cell?
- A.
  
  Ribosomes
- B.
  
  Golgi Apparatus
- C.
  
  Nucleolus
- D.
  
  Cell Wall
- E.
  
  Cytoplasm
Correct Answer
A. Ribosomes

Explanation
The arrow is pointing to the dot that represents ribosomes. Ribosomes are responsible for protein synthesis in the cell, and they can be found in the cytoplasm or attached to the endoplasmic reticulum. They are composed of RNA and proteins, and they play a crucial role in the production of proteins necessary for the cell's functions.

What is the FUNCTION of the part pointed to below? In other words, what does it do?
- A.
  
  Produces carbohydrates
- B.
  
  Acts like a storage unit for the cell
- C.
  
  Packages and distributes material throughout and out of the cell
- D.
  
  Acts like the garbage disposal of the cell and processes waste
- E.
  
  Controls what goes in and out of the cell
Correct Answer
E. Controls what goes in and out of the cell

Explanation
The part pointed to in the question is most likely referring to the cell membrane. The cell membrane controls what goes in and out of the cell by acting as a selective barrier. It regulates the movement of molecules and ions, allowing certain substances to enter or leave the cell while preventing others from doing so. This function is crucial for maintaining homeostasis and ensuring the cell's proper functioning.

Name two structures that plants and animals DO NOT SHARE.
11.

Which of the following IS NOT a primary chemical in cells?
- A.
  
  Carbohydrates
- B.
  
  Proteins
- C.
  
  Lipids
- D.
  
  Minerals
- E.
  
  Nucleic Acids
Correct Answer
D. Minerals

Explanation
Minerals are not considered primary chemicals in cells. While carbohydrates, proteins, lipids, and nucleic acids are all essential components of cells and play vital roles in various cellular processes, minerals are inorganic substances that are required in much smaller quantities for specific functions in the body, such as enzyme activation and maintaining osmotic balance. They are not considered primary chemicals because they are not directly involved in the structure or function of cells.

Which of the TWO primary chemicals in cells provide cells energy? REMEMBER TO SELECT TWO.
- A.
  
  Carbohydrates
- B.
  
  Proteins
- C.
  
  Lipids
- D.
  
  Minerals
- E.
  
  Nucleic Acids
Correct Answer(s)
A. Carbohydrates
C. Lipids

Explanation
Carbohydrates and lipids are the two primary chemicals in cells that provide cells with energy. Carbohydrates are broken down into glucose, which is then used by the cells for energy production. Lipids, on the other hand, are stored in the body as fat and can be broken down to release energy when needed. Both carbohydrates and lipids play crucial roles in cellular energy metabolism.

Which of the following is an AUTOTROpH?
- A.
  
  Fish
- B.
  
  Butterfly
- C.
  
  Tree
- D.
  
  Shrimp
- E.
  
  Rabbit
Correct Answer
C. Tree

Explanation
An autotroph is an organism that can produce its own food through photosynthesis or chemosynthesis. Trees are autotrophs because they use photosynthesis to convert sunlight, water, and carbon dioxide into glucose, which is their source of energy. Fish, butterfly, shrimp, and rabbit are not autotrophs as they rely on consuming other organisms for their energy needs.

Which of the following is a heterotroph?
- A.
  
  Ant
- B.
  
  Apple Tree
- C.
  
  Flower
- D.
  
  Grass
- E.
  
  Wheat
Correct Answer
A. Ant

Explanation
Ant is the correct answer because a heterotroph is an organism that obtains its energy by consuming other organisms. Ants are consumers and obtain their energy by feeding on other organisms, such as dead insects, nectar, or plant sap. Apple trees, flowers, grass, and wheat are all autotrophs, meaning they can produce their own food through photosynthesis.
