4.5 Mitochondria and Chloroplasts: Cellular Generators
What is a chloroplast?
A cell like organelle present in algae and plants that contain chlorophyll and carries out photosynthesis.
What is an amyloplast?
A plant organelle called a plastid that specializes in storing starch.
What are granna (granum)?
A stacked column of flattened, interconnected disks that are part of the thylakoid membrane system in CHLOROPLASTS
What is a plastid?
An organelle in the cells of photosynthetic eukaryotes that is the site of photosynthesis
What is the structure of mitochondria?
Mitochondria are bounded by two membranes: a smooth outer membrane, and an inner folded membrane with numerous contiguous layers called cristae
What surrounds the thylakoid?
Surrounding the thylakoid is a fluid matrix called the STROMA.
What is mitochondria?
The powerhouse of the cell. tubular or sausage-shaped. found in ALL eukaryotic cells
What is important about the DNA in mitochondria?
This DNA contains several genes that produce proteins essential to the mitochondrion's role in oxidative metabolism.
Mitochondria have their own __________.
DNA
What is the matrix?
INNERMOST PART OF MITOCHONDRIA
What does the STROMA contain?
The enzymes used to synthesize glucose during photosynthesis are found in the stroma.
What is endosymbiosis?
The theory that proposes that eukaryotic cells evolved from a symbiosis between different species of prokaryotes.
What is on the surface of the thylakoids?
light-capturing photosynthetic pigments
