= water= ion= energy= protein

CELL RESPIRATION VS PHOTOSYNTHESIS

9B compare the reactants and products of photosynthesis and cellular respiration in terms of energy and matter

4Binvestigate and explain cellular processes, including energy conversions

PHOTOSYNTHESIS / Mitochondria
Chloroplast / Produce sugars and oxygen
C6H12O6 + 6O2--> 6CO2 + 6H2O / Produce carbon dioxide and water
6CO2 + 6H2O --> C6H12O6 + 6O2 / Plants
Animals / Plants
Glucose sugar combusts with oxygen / Carbon dioxide + water + ATP energy
Carbon dioxide + water + solar energy / Sunlight reacts carbon dioxide and water

CELLS / Both / VIRUSES

VIRAL REPLICATION

Place events in viral replication in the correct or, 1- 5

______a)Assembly – Cellular activity of the host cell help assemble new viruses until the host cell is filled with new viruses.

______b)Attachment – A virus comes attaches to host cell (lock and key attachement)

______c)Entry –DNA or RNA is injected into host cell.

______d)Release – When assembling is complete, the virus particles release enzymes that digest the host cell wall. The new virus particles released go to infect new cells where the cycle is repeated.

______e)Replication – When inside a cell, the virus takes over and instructs the host cell to make more viral DNA and proteins

Lytic or Lysogenic?

______: when the virus releases its DNA, the cell is tricked into making new viruses and dies after the new viruses burst out. The cell dies and there are new viruses made in the process.
______: the viral DNA becomes part of the original DNA, and the cell lives and reproduces with the viral DNA.

Draw and label the stages of the lytic cycle

Draw and label the stages of the lysogenic cycle
