Question:
What is a Haploid Cell?
Answer:
A cell that contains one complete set of chromosomes, typically found in gametes.
Question:
What is Meiosis?
Answer:
A type of cell division that reduces the chromosome number by half, producing four
haploid cells, essential for sexual reproduction.
Question:
What is Mitosis?
Answer:
A process of cell division that results in two genetically identical daughter cells,
maintaining the same chromosome number.
Question:
What is Diffusion?
Answer:
The process by which molecules spread from areas of high concentration to areas of
low concentration.
,Question:
What is Osmosis?
Answer:
The diffusion of water molecules through a semipermeable membrane from a region of
lower solute concentration to a region of higher solute concentration.
Question:
What is a Cell?
Answer:
The basic structural and functional unit of all living organisms.
Question:
What is a Mitochondrion?
Answer:
An organelle that produces energy through cellular respiration, often referred to as the
powerhouse of the cell.
Question:
What is a Cell Membrane?
Answer:
A biological membrane that separates and protects the interior of all cells from the
outside environment.
Question:
What is a Nucleus?
Answer:
The membrane-bound organelle that contains the cell's genetic material and controls
its activities.
Question:
What is a Chromosome?
Answer:
A thread-like structure made of DNA and proteins that contains genetic information.
,Question:
What is Cytoplasm?
Answer:
The jelly-like substance within a cell that contains organelles and is the site of many
metabolic processes.
Question:
What are Organelles?
Answer:
Specialized structures within a cell that perform specific functions.
Question:
What are Gametes?
Answer:
Reproductive cells (sperm and eggs) that are haploid and combine during fertilization.
Question:
What is the Muscular System?
Answer:
The organ system that enables humans and animals to move using the muscular
tissues.
Question:
What is the Circulatory System?
Answer:
The system that circulates blood and lymph through the body, consisting of the heart,
blood vessels, and blood.
Question:
What is the Respiratory System?
Answer:
The system responsible for the exchange of gases (oxygen and carbon dioxide) in the
body.
, Question:
What is the Digestive System?
Answer:
The system that breaks down food into nutrients that can be absorbed and used by the
body.
Question:
What are Enzymes?
Answer:
Biological catalysts that speed up chemical reactions in the body.
Question:
What is Photosynthesis?
Answer:
The process by which green plants and some other organisms use sunlight to
synthesize foods with the help of chlorophyll.
Question:
What is the Nitrogen Cycle?
Answer:
The series of processes by which nitrogen and its compounds are interconverted in the
environment and in living organisms.
Question:
What is Heredity?
Answer:
The passing of traits from parents to offspring through genes.
Question:
What is DNA?
Answer:
Deoxyribonucleic acid, the molecule that carries the genetic instructions for life.
