The organelles that scientists believed that it originated by symbiotic relationships between primitive eukaryotes and certain prokaryotes is known as chloroplast. Chloroplast contain chlorophyll which capture energy from sunlight that is used in photosynthesis .This energy is converted to ATP and NADPH
Answer:
a.Many mitochondrial genes resemble proteobacteria genes, while the genes in the chloroplast resemble genes found in some photosynthetic bacteria.
c.Mitochondria and chloroplasts both have their own circular DNA and 70S ribosomes that are similar to those found in bacteria.
d.Mitochondria and chloroplasts replicate by a process similar to mitosis.
Explanation:
Endosymbiotic theory states that mitochondria and chloroplast which are organelles of eukaryotic cells were once independently living micro-organisms but with due course of time eukaryotic cells engulfed them and they become an integral part of these eukaryotic cells.
The resemblance between mitochondrial genes with those of proteobacteria and chloroplast genes with photosynthetic bacteria strongly support endosymbiotic theory. Apart from this, the presence of their own DNA that too circular just like prokaryotic microbes and 70 S ribosomes also support this theory. Also just like prokaryotic cells, before cell division mitochondria and chloroplasts undergo replication by means of a process known as binary fission.
Answer:
it tells you all the answers
Explanation:
Answer:
balanced
Explanation:
Equal forces are being applied from opposite sides, so they cancel out. Think about pushing on both sides with the same amount of pressure on both sides. Its not gonna move. Hope I could help!
