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?

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?

Cell need energy, ATP, to carry out all chemical functions to make our bodies run properly.
