Genetics
What is a phenotype?
The way an individual LOOKS
Ex: curly hair
What body system is made of bones, cartilage and ligaments?
Skeletal
What is the energy source that drives photosynthesis?
the sun
What is the main purpose of cellular respiration?
A. To produce glucose
B. To store DNA
C. To release energy from food
D. To create new cells
C. To release energy from food
A gene is....
A section of a chromosome/DNA that codes for a protein
What is the job of a receptor?
Gets a message from protein
What does the respiratory system do?
Lungs bring oxygen (O2) into the blood and Carbon Dioxide (CO2) out
What is the main purpose of photosynthesis in plants?
To make glucose using sunlight
What organelle carries out Cellular Respiration? (hint: the powerhouse of the cell)
Mitochondria
What organelle carries out Photosynthesis?
Chloroplast
What is a genotype?
Combination of alleles
What happens to starch in the mouth?
Amylase (enzymes) in the spit break starch down into glucose
Chemical Reaction!
How are photosynthesis and respiration connected?
Photosynthesis makes the oxygen needed for respiration.
Which gas is produced during cellular respiration?
CO2
Which two systems work together to deliver oxygen to cells?
Respiratory and Circulatory
What is the difference between homozygous and heterozygous?
Homozygous= 2 of the same alleles (bb or BB)
Heterozygous= 2 different alleles (Bb)
What body system is responsible for transporting nutrients and oxygen?
Circulatory
What is a product of photosynthesis that plants use for energy and growth?
Glucose
Which statement best describes the relationship between photosynthesis and cellular respiration?
A. They produce the same products.
B. The products of photosynthesis are the reactants for respiration.
C. They both require sunlight.
D. They occur only in animals.
B. The products of photosynthesis are the reactants for respiration.
If tall (T) is dominant and short (t) is recessive, which genotype would result in a short plant?
tt
SpongeBob is heterozygous for his square shape, but SpongeSusie is round.
Create a Punnett square to show the possibilities that would result if SpongeBob and SpongeSusie had children.
Square= R round=r
The main function of the digestive system is...
Break down food into nutrients
CO2 + H2O + Sun --> Glucose + O2
Write the full equation for Cellular Respiration
FO--> ECW
Glucose + O2 --> Energy + Carbon Dioxide + Water
A Punnett Square is used to...
Predict the probability of genetic traits
