Cell Thoery
The cell theory states that all living things are made of _________
Cells
What is the function of the nucleus in the cell?
The nucleus is the control center of the cell
The cell membrane
What is the main purpose of photosynthesis?
For plants to absorb sunlight energy to make their own food (glucose)
What gas do cells need in order to perform cellular respiration?
Which scientist coined the term "cell" after observing a cork under the microscope?
Robert Hooke
Which organelle is known as the powerhouse of the cell? WHY?
The mitochondria because it is used in cellular respiration to make energy
What is the main process cells use to move materials from an area of high concentration to an area of low concentration?
Diffusion
In which organelle does photosynthesis take place?
Chloroplast
What is the main purpose of cellular respiration?
To break down glucose and release energy for the cell
Name the 3 statements of the cell theory

Which organelle carries out cellular respiration for most cells?
Single-celled organisms are considered living because...
What is the job of the cell membrane?
The cell membrane controls what material leaves and enters the cell
What is the process called that requires energy to move material from low concentration to high concentration?
Active Transport
What three reactants do plants need for photosynthesis?
Water, Sunlight energy, Carbon Dioxide
What molecule is broken down during cellular respiration to release energy?
True or False: All organisms can repair themselves
TRUE!! All living organisms are able to reproduce new cells needed for repair and growth
The vacuole
How do cells get rid of large materials that cannot pass through the membrane?
Exocytosis
