What is a Cell?
- A.
An organism which is made of one cell
- B.
The basic unit of all organisms
- C.
The diffusion of water
Correct Answer
B. The basic unit of all organismsExplanation
A cell is the basic unit of all organisms. It is the smallest structural and functional unit of life. Cells can exist as single-celled organisms or as part of a multicellular organism. They contain all the necessary components to carry out the processes of life, such as metabolism, reproduction, and response to stimuli. Cells can vary in size, shape, and function depending on the organism they belong to. They are responsible for the growth, development, and maintenance of an organism.Rate this question:

what is Unicellular?
- A.
A cell which has a specific function to perform
- B.
The basic unit of all madder
- C.
An organism which is made of one cell
Correct Answer
C. An organism which is made of one cellExplanation
Unicellular refers to an organism that is composed of a single cell. Unlike multicellular organisms, which are made up of multiple cells, unicellular organisms carry out all of their life processes within a single cell. This includes functions such as reproduction, metabolism, and responding to their environment. Examples of unicellular organisms include bacteria, protozoa, and some types of algae.Rate this question:

what is Multicellular?
- A.
A group of tissues
- B.
Anything which can independently carry out life processes
- C.
An organism which is made of more than one cell
Correct Answer
C. An organism which is made of more than one cellExplanation
Multicellular refers to an organism that is composed of more than one cell. This means that the organism has multiple cells working together to carry out life processes and functions. Unlike unicellular organisms, which are made up of only one cell, multicellular organisms have specialized cells that perform specific functions and work in coordination with each other. This allows multicellular organisms to have a higher level of complexity and organization, enabling them to carry out more complex life processes.Rate this question:

Cell membrane is?
- A.
Flexible structure which surrounds a cell and controls the movement of materials in and out of the cell
- B.
Protein which requires energy
- C.
A cell group of cells
Correct Answer
A. Flexible structure which surrounds a cell and controls the movement of materials in and out of the cellExplanation
The cell membrane is a flexible structure that surrounds a cell and controls the movement of materials in and out of the cell. It acts as a barrier, allowing certain substances to enter and exit the cell while preventing others from doing so. This selective permeability is crucial for maintaining the cell's internal environment and ensuring its proper functioning.Rate this question:

what is Specialized cell?
- A.
A group of organs
- B.
A group of cells
- C.
A cell which has a specific function to perform
Correct Answer
C. A cell which has a specific function to performExplanation
A specialized cell is a cell that is uniquely adapted to perform a specific function within an organism. Unlike a group of organs or a group of cells, a specialized cell is an individual cell that has developed specific structures and characteristics to carry out a particular task efficiently. These cells have specific features that enable them to perform their designated function effectively, such as red blood cells for oxygen transport or nerve cells for transmitting electrical signals.Rate this question:

Active transport is?
- A.
The movement of particles through a protein which requires energy
- B.
The movement of particles through a protein which does NOT require energy
- C.
Movement of water
Correct Answer
A. The movement of particles through a protein which requires energyExplanation
Active transport is the process of moving particles through a protein that requires energy. This means that the movement of particles is against their concentration gradient, from an area of lower concentration to an area of higher concentration. This process is essential for many biological functions, such as the uptake of nutrients by cells or the removal of waste products. The energy required for active transport is usually provided by ATP, the main energy currency of cells.Rate this question:

what is Passive transport?
- A.
Movement of water
- B.
The movement of particles through a protein which does NOT require energy
- C.
The movement of particles through a protein which requires energy
Correct Answer
B. The movement of particles through a protein which does NOT require energyExplanation
Passive transport refers to the movement of particles through a protein without the need for energy. This process occurs spontaneously, driven by the concentration gradient. Unlike active transport, which requires energy in the form of ATP, passive transport allows particles to move freely across the cell membrane without the need for additional energy expenditure. This can occur through various mechanisms such as diffusion, facilitated diffusion, and osmosis.Rate this question:

Organism is ?
- A.
Anything which can independently carry out life processes
- B.
Movement of particals through a protein
- C.
The diffusion of water
Correct Answer
A. Anything which can independently carry out life processesExplanation
An organism is defined as anything that can independently carry out life processes. This means that it is capable of performing essential functions such as growth, reproduction, metabolism, and response to stimuli. Organisms can range from microscopic single-celled organisms to complex multicellular organisms like plants and animals. They have the ability to maintain homeostasis and adapt to their environment. The given answer accurately describes the concept of an organism.Rate this question:

diffusion is?
- A.
The movement of particles from an area of high concentration to low concentration
- B.
The diffusion of water
- C.
A clock
Correct Answer
A. The movement of particles from an area of high concentration to low concentrationExplanation
Diffusion is the process by which particles move from an area of high concentration to an area of low concentration. This movement occurs due to the random motion of particles and does not require any external energy input. It is a passive process that helps in achieving equilibrium and equal distribution of particles throughout a medium.Rate this question:
