BIOL 215 Lecture 5

Symbiosis

Symbiosis

________: a close, long- term interaction between two species.

endomembrane system

The ________ originated from the infolding of the plasma membrane to increase available surface area.

Mitochondria

________ and chloroplasts are similar in size to prokaryotes.

Photosynthetic organisms

________ also have mitochondria.

Phagosomes

________: vacuoles storing food that the cell takes in.

Chloroplasts

________ are related to cyanobacteria.

Plant cells

________ have one large vacuole while animal cells have multiple small vacuoles.

modern mitochondria

The ________ and chloroplasts used to be free- living prokaryotes that were engulfed by larger prokaryotes.

large prokaryote

Outer membrane maybe originated from phagocytosis when the mitochondria or chloroplast was engulfed by a(n) ________.

Horizontal gene

________ transfer: non- sexual movement of genetic information between genomes of the same generation.

mitochondria

The ________ or chloroplast and host transferred DNA amongst each other by horizontal gene transfer.

Chloroplasts

________ are the site of photosynthesis.

Mitochondria

________ are found in most eukaryotes.

Mitochondria

________ and chloroplasts replicate by binary fission.

mitochondria

The ________ or chloroplast and the larger prokaryotic cell developed a symbiotic relationship.

Mitochondria

________ are related to proteobacteria.

Vacuoles

storage compartments formed by a lipid bilayer

Phagosomes

vacuoles storing food that the cell takes in

Contractile vacuoles

vacuoles that expand and contract to expel excess water in the cell
