This is a disease-causing agent.

virus DNA or RNA

Protein coat

Prokaryotes

Eukaryotes

So, what’s the major difference?

_________________________________

is the structure found in eukaryotes but not in prokaryotes.

Nucleus

GOLGI APPARATUS

GOLGI APPARATUS

It is an organelle.It packages proteins into

vesicles.

Amino acids• These ______________ are the building

blocks of proteins. They band together in chains to form the stuff from which life is born. This is a two-step process: first, they get together and form peptides or polypeptides, and it is from these groupings that proteins are made.

Photosythesis

*In the process, sugar is made.

*Is light dependent reactions.

*Chloroplasts are found in plant cells.*Chloroplasts use the energy stored in ATP.

*Chloroplasts use carbon dioxide.

*When monomers are linked together, what are they called?

*When amino acids are linked together,what are they called?

They are called polymers.

They are called proteins.

Diffusion vs. Osmosis

Explain what is happening here.

Osmosis

Osmosis in cells

Cells have a special kind of energy.

• Low concentration• High concentration• Equilibrium• Movements of molecules• Diffusion• Osmosis• Semipermeable membrane………

What do you th

ink cells

are capable to

doing?

How do cells move a material from an area of low concentration across a membrane into an area of higher concentration?

A. Facilitate diffusion, which does not require using energy.

B. Facilitate diffusion, which requires using energy.

C. Active transport, which requires using energy.

D. Active transport, which does not require using energy.
