Cell Theory Flashcards
What is a cell
Smallest living unit in all living things (organisms)
What are unicellular organisms
One cell organisms
What are multicellular
Organisms with 2 or more cells
What do all cells come from
Pre-existing cells
What can you see inside cells
Organelles
A nucleus’ primary function is. . .
To produce and assemble the cell’s ribosomes
What is the boundary of the cell
Cell membrane
What is the cell walls use
The cell wall surrounds the cell membrane, it supports and protects the cell wall.
What does the vacuole do
In plant cells the vacuole helps maintain water balance
What is the role of the chloroplast
It produces energy through photosynthesis
What breaks down sugar and releases energy to power the cell’s life processors
The mitochondrion
What does the cell wall do
The cell wall surrounds the cell membrane and supports as well as protects the plant cell
What does the cell membrane do
It transports nutrients into the cell and transports toxic substances out of the cell
What does the cell membrane do
It transports nutrients into the cell and transports toxic substances out of the cell
What is used in photosynethesis
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar
What is the equation of photosynthesis
6CO2 + 6H2O → C6H12O6 + 6O2.
What is the difference between photosynthesis and respiration
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are byproducts and ATP is energy that is transformed from the process.
What is used in respiration in plants
The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth
What is the equasion for respiration
C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water)
What is the use of respiration
The lungs and respiratory system allow us to breathe. Respiration is essential for growth and maintenance of all plant tissues,
What is the use of photosynthesis
Plants use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel
what is cytosole
The cytosol is the liquid medium contained within a cell
