Cell Theory
What is cell theory?
Cell theory states that all living things are made up of cells, cells are the basic unit of life, and all cells come from pre-existing cells.
What is the function of the nucleus?
The nucleus stores genetic material (DNA) and controls the cell's activities.
What is an organism?
An organism is any living thing, including plants, animals, and microorganisms.
What is biology?
Biology is the study of life and living organisms.
What are the three parts of cell theory?
1) All living things are composed of cells. 2) Cells are the basic unit of life. 3) All cells come from existing cells.
What do ribosomes do?
Ribosomes are responsible for protein synthesis.
Give an example of a unicellular organism.
An example of a unicellular organism is a bacterium or an amoeba.
What do biologists study?
Biologists study various aspects of living organisms, including their structure, function, growth, evolution, and interactions.
Who is credited with developing cell theory?
The development of cell theory is credited to scientists like Schleiden, Schwann, and Virchow.
What is the role of the cell membrane?
The cell membrane regulates what enters and exits the cell, providing protection and support.
What is a multicellular organism?
A multicellular organism is an organism composed of multiple cells that work together, such as humans or plants.
What are the characteristics of living things?
Characteristics of living things include growth, reproduction, response to stimuli, metabolism, and homeostasis.
What does the term "cell" mean?
A cell is the smallest structural and functional unit of living organisms.
What is a mitochondrion?
Mitochondria are the powerhouse of the cell, generating ATP
What is homeostasis?
Homeostasis is the ability of an organism to maintain stable internal conditions despite changes in the external environment.
What is the life cycle?
The life cycle is the series of changes that an organism goes through from birth to death.
Why is the cell considered the basic unit of life?
Cells perform all essential life processes such as metabolism, growth, and reproduction, making them the fundamental unit of life.
What is the difference between prokaryotic and eukaryotic cells?
Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.
How do organisms adapt to their environment?
Organisms adapt through evolutionary changes that enhance their survival and reproduction in specific environments.
Why is the study of biology important?
The study of biology is important for understanding living systems, improving health, and addressing environmental issues.
