Characteristics for Life
- Energy, reproduction, responding, waste, growth
List the five characteristics for life.
What are light (energy), water, and carbon dioxide?
These three ingredients are required for photosynthesis.
What is the nucleus?
This organelle is responsible for controlling the functions of the cell and stored DNA
What is a virus?
I am non-living and attack cells around me.
True or false: in diffusion, a solute flows from a low concentrated to a highly concentrated area.
False
What is reproduction?
Two adults have a child. Which characteristic for life does this represent?
What are oxygen and sugar?
These two ingredients are required for cellular respiration.
What is a cell wall?
This organelle is only present in plant and bacteria cells.
Cellulose in plants
What infection causes red rash and high fever, who does it infect mostly and how can prevent it
Measles, children and vaccine
What is crenation?
animal cell shrinks
What is in your stomach that kills pathogens?

What is the chloroplast?
This organelle is the site of photosynthesis. Has chlorophyll

When a cell is put into a hypertonic solution, what happens to the cell.
What is water leaves the cell and the cell shrivels up
What is mitosis used for?
growth and repair
What is a bacterium?
This kind of cell uses a flagella to motor itself around, pathogen and can cause illness
What is the mitochondria?
Site of respiration where energy is transferred from glucose and oxygen
How are vaccines produced
What is the difference between osmosis and diffusion?
Osmosis is water and diffusion is all three particle types
What is respiration?
Oxygen + Glucose = Carbon dioxide and water
Who is Alexander Flemming?
Discovered penicillin which is an antibiotic
What are ribosomes?
This organelle is present in plant cells, animal cells, and bacteria cells where protein synthesis takes place
What are the steps of virus reproduction.
The virus attaches to a host cell. It releases its DNA into the host. The DNA joins in with the host's DNA. The host copies the viral DNA thinking that it is its own. The proteins made by the viral DNA begin to assemble into new viruses. The new viruses break out of the host, killing it in the process.
Explain what isotonic is?
When water is equal inside and outside the cell
