Many organisms are composed of many cells, performing many jobs within the body. What are these types of organisms known as?
-
Unicellular
-
Multicellular
-
Bicellular
-
Polycellular
Correct Answer
A. MulticellularExplanation
Multicellular organisms are composed of many cells that perform different functions within the body. These cells work together to carry out various tasks and maintain the overall functioning of the organism. Unlike unicellular organisms, which consist of only one cell, multicellular organisms have specialized cells that are organized into tissues, organs, and systems. This allows them to have a higher level of complexity and perform a wider range of functions. Therefore, the correct answer is multicellular.Rate this question:

The "mini-organs" that help the cell perform their daily functions are known as what?
-
Organs
-
Tissues
-
Systems
-
Organelles
Correct Answer
A. OrganellesExplanation
Organelles are the "mini-organs" within cells that carry out specific functions necessary for the cell's survival. They are responsible for tasks such as energy production, protein synthesis, and waste removal. Each organelle has a specific structure and function, working together to maintain the overall health and functionality of the cell. Examples of organelles include the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus.Rate this question:

In which type of cell would you find a cell wall and a chloroplast?
-
Plant
-
Animal
Correct Answer
A. PlantExplanation
A cell wall is a rigid structure that provides support and protection to the cell. It is found in plant cells but not in animal cells. On the other hand, chloroplasts are organelles that carry out photosynthesis, the process by which plants convert sunlight into energy. Chloroplasts are also found only in plant cells. Therefore, the correct answer is plant because plant cells have both a cell wall and chloroplasts.Rate this question:

Which organelle helps to produce proteins for the cell?
-
Ribosomes
-
Vacuole
-
Nucleus
-
Cell Membrane
Correct Answer
A. RibosomesExplanation
Ribosomes are the organelles responsible for protein synthesis in the cell. They are found in both prokaryotic and eukaryotic cells and can be free-floating in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes read the genetic information stored in RNA molecules and use it to assemble amino acids into proteins. This process is essential for the growth, repair, and functioning of cells. Therefore, ribosomes are the correct answer as they play a vital role in producing proteins for the cell.Rate this question:

Which organelle acts as the "brain" of the cell?
-
Nucleus
-
Mitochondria
-
Golgi Apparatus
-
Ribosomes
Correct Answer
A. NucleusExplanation
The nucleus acts as the "brain" of the cell because it contains the cell's genetic material, including DNA, which controls the cell's activities and determines its characteristics. The nucleus also directs the synthesis of proteins and is involved in cell division. It plays a crucial role in regulating and coordinating the cell's functions, making it the control center or "brain" of the cell.Rate this question:

Which organelle processes energy and helps animal cells go through cellular respiration?
-
Nucleus
-
Lysosome
-
Vacuole
-
Mitochondria
Correct Answer
A. MitochondriaExplanation
Mitochondria is the correct answer because it is the organelle responsible for processing energy and facilitating cellular respiration in animal cells. It is often referred to as the "powerhouse" of the cell as it produces ATP, the main source of energy for cellular activities. Mitochondria have their own DNA and can self-replicate, suggesting their evolutionary origin from independent bacteria that formed a symbiotic relationship with eukaryotic cells.Rate this question:

- 8.
Which organelle surrounds the outside of animal cells?
-
Cell Wall
-
Cell Membrane
-
Nuclear Membrane
-
Nucleolus
Correct Answer
A. Cell MembraneExplanation
The cell membrane is the correct answer because it is a thin, flexible barrier that surrounds the outside of animal cells. It acts as a protective layer, controlling the movement of substances in and out of the cell. The cell membrane is made up of a phospholipid bilayer with embedded proteins, allowing it to selectively regulate the passage of molecules and ions. Unlike plant cells, animal cells do not have a cell wall, making the cell membrane the outermost boundary of the cell.Rate this question:

All living things are made up of _____________.
-
Cells
-
Minerals
-
Electrons
-
Protons
Correct Answer
A. CellsExplanation
Living things are made up of cells, which are the basic structural and functional units of life. Cells are responsible for carrying out all the necessary processes for the survival and growth of an organism. They provide structure, perform metabolic functions, and contain genetic material. Without cells, living things would not be able to carry out essential functions such as reproduction, growth, and response to stimuli. Therefore, cells are the fundamental building blocks of all living organisms.Rate this question:

In multicelluar organisms, cells perform different _____________.
-
Jobs
-
Colors
-
Organs
-
Magic tricks
Correct Answer
A. JobsExplanation
In multicellular organisms, cells perform different jobs. This is because different cells have specialized functions and tasks that contribute to the overall functioning of the organism. Each cell type is responsible for carrying out specific processes and activities that are necessary for the survival and maintenance of the organism. These jobs can include tasks such as nutrient absorption, waste removal, reproduction, movement, and communication. By dividing labor and having specialized cells, multicellular organisms can efficiently carry out various functions required for their survival and growth.Rate this question:
