AP Bio Chapter 6.2 Part 2 Flashcards
What are stroma and what does it contain
Liquid inside inner membrane, contains DNA and Ribosomes and enzymes. Where sugar is made
Structure of chloroplasts
Outer membrane
Inner membrane
Stroma
Thylakoids
What are thylakoids and what is made there
Membraneous sacs inside an inner membrane. Where AP is made
What are stacks of thylakoids
Grana
What is the function of photosynthesis
Building (anabolism) of sugar from ATP, CO2 and light. Produces O2 as waste.
Only ______________ cells have chloroplasts
Plant like
How are the mitochondria and chloroplast similar
Both transform energy
Both generate ATP
Both have double membranes
Both are semi-autonomous organelles (not part of endomembrane system)
Both move, change shape, and divide on their own
Both have small internal ribosomes, circular DNA and make their own protein enzymes.
Chloroplasts are in a group of organelles called
Plastids
What are plastids the products of
Endosymbiosis
Where does DNA sequence analysis put plastid ancestors near
modern Cyanobacteria
Similar patterns of what are seen in algae’s too
Plastid evolution and diversification
Semi-autonomous
Divides on its own
What percent of energy does anaerobic processes utilize
2%
What percent of energy does aerobic processes utilize
38%
Endosymbiosis
The theory of mitochondria and chloroplast being swallowed by a cell
