What is the primary function of the chloroplast?
What is the primary function of the chloroplast?
- Protein synthesis
- Photosynthesis (correct)
- Genetic storage
- ATP production
Cellular respiration occurs within the chloroplasts of a cell.
Cellular respiration occurs within the chloroplasts of a cell.
False (B)
Describe the concept of co-dominance in genetics using an example.
Describe the concept of co-dominance in genetics using an example.
Co-dominance occurs when both alleles for a trait are fully expressed. For example, a flower with both red and white alleles displays patches of both colors rather than a blended color.
The 'powerhouse' of the cell is known as the _______.
The 'powerhouse' of the cell is known as the _______.

Flashcards
Photosynthesis
Photosynthesis
The process by which plants convert light energy into chemical energy in the form of glucose. It releases oxygen as a byproduct.
Chloroplast
Chloroplast
The organelle responsible for photosynthesis in plants.
Cellular Respiration
Cellular Respiration
The process by which cells break down glucose to release energy in the form of ATP. It requires oxygen and produces carbon dioxide as a byproduct.

Study Notes
Biology Quiz Review
-
Photosynthesis Location: Chloroplasts are the organelles responsible for photosynthesis in plant cells.
-
Cellular Respiration Product: The primary product of cellular respiration is ATP, the cell's energy currency.
-
Natural Extinction Cause: Climate change is a natural factor that can lead to species extinction.
-
Co-dominance Definition: A co-dominant inheritance pattern means both alleles are fully expressed in a heterozygote (hybrid).
-
Photosynthesis Gas Release: Photosynthesis releases oxygen into the atmosphere.
Cell Structure and Function
-
Mitochondria Function: Mitochondria are the "powerhouses" of the cell, responsible for energy production.
-
Chloroplast Function: Chloroplasts are essential for photosynthesis, the process of converting light energy into chemical energy.
-
Ribosomes Role: Ribosomes are responsible for protein synthesis.
Extinction
-
Human vs Natural Extinction Causes: Extinction can result from both natural causes (like climate change) and human activities (pollution or deforestation).
-
Biodiversity Importance: Biodiversity enriches the stability, productivity, and resilience of ecosystems. It's more than just the number of species.
Genetics
- Incomplete Dominance: Incomplete dominance results in a blended phenotype in heterozygotes, unlike complete dominance where one allele masks the other. For example, pink snapdragons from red and white parents.
Processes
-
Cellular Respiration Purpose: Cellular respiration converts glucose into ATP, a key energy source for cellular activities.
-
Color Perception: Objects appear colored because they reflect specific wavelengths of light. They absorb the other colors.
