So, what’s the major difference?

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.

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.
