Biology Review
What is an object called that is alive now or was once alive?
A LIVING OBJECT
Is the object below a living or nonliving object?
NONLIVING
The Cell Theory is composed of 3 different parts. Identify the missing part.
1.All living things are made of cells2.Cells are the basic unit of life3.Cells only come from _________ _________
OTHER LIVING CELLS
What are the 2 main differences between plant and animal cells?
Plant cells have a cell wall and chloroplast
Which cell organelle is the outer boundary of the cell?

The cell membrane
What organelle produces energy for the cell? It is also known as the powerhouse of the cell.
The ribosomes in the cell are responsible for making ____________.
protein
When a dog pants, it is trying to maintain a level body temperature. This is an example of what process?
The balance that all living things have to maintain, is
called HOMEOSTASIS.
Particles are always moving around. They move from areas that more crowded to areas that are less crowded. This process is called ______________________.
DIFFUSIONDIFFUSION
crowdedcrowded less crowdedless crowded
Diffusion occurs in cells too. What organelle allows diffusion to take place by allowing things to enter and exit the cell?
Cell Membrane
is the diffusion of _______
Water
Like Passive Transport (diffusion/osmosis), Active Transport moves particles in and out of the cell, but this time it moves them from less crowded to MORE crowded.
When moving particles against the crowd, it requires ____________.
Energy
In what cells does photosynthesis occur?
Plants
Glucose (Sugar) and Oxygen
+ water + energy glucose + oxygencarbondioxide
6CO2 6H2O C6H12O6 6O2light
energy+ ++
In what cellular organelle does photosynthesis take place?
Chloroplast
What process breaks down glucose and oxygen to produce water, carbon dioxide and ENERGY (ATP)?
Cellular Respiration
In what cellular organelle does
cellular respiration take
place?
Mitochondria – the powerhouse of the cell
In order for your computer to
work, it needs electric
ity.
Electricity is a type of energy.
Cellular respiration produces
energy called ATP. Why is this
important?
Cells need energy, ATP, to carry out all chemical functions to make our bodies run properly.
+ water + energy glucose + oxygencarbondioxide
6CO2 6H2O C6H12O6 6O2light
energy+ ++
The equation below is for what process?
PHOTOSYNTHESIS
This cellular organelle is often called the “brain” of the cell. It contains the DNA.
Nucleus
This cellular organelle is used as a storage system. It stores food, nutrients and/or waste.
Vacuole
