Answer:
Non-green plants cannot make their own food because they do not have chlorophyll in their leaves which breaks down carbon dioxide and water molecules thus do not produce glucose(food).
Answer:
A. engulfing of small photosynthetic prokaryotes by larger cell
Explanation:
The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. In this theory, the first eukaryotic cell was probably an amoeba-like cell that got nutrients by phagocytosis and contained a nucleus that formed when a piece of the cytoplasmic membrane pinched off around the chromosomes. Some of these amoeba-like organisms ingested prokaryotic cells that then survived within the organism and developed a symbiotic relationship.
Some Evidence for this is based on the following:
1. Chloroplasts are the same size as prokaryotic cells, divide by binary fission, and, like bacteria, have Fts proteins at their division plane.
2. The mitochondria are the same size as prokaryotic cells, divide by binary fission, and the mitochondria of some protists have Fts homologs at their division plane.
3. Mitochondria and chloroplasts have their own DNA that is circular, not linear.
4. Mitochondria and chloroplasts have their own ribosomes that have 30S and 50S subunits, not 40S and 60S.
5. Several more primitive eukaryotic microbes, such as Giardia and Trichomonas have a nuclear membrane but no mitochondria.
Answer:
C) Protein synthesis is the process through which cells read DNA and build the molecular components of new cells.
Explanation:
DNA is the genetic material of the organisms. It stores the genetic information used to make the molecules and other components required for the new cells. This process of formation of molecules is called protein synthesis. During protein synthesis, The DNA forms a complementary messenger RNA (mRNA) in the nucleus of a cell. Synthesis of mRNA from DNA is called transcription. The mRNA released into the cytoplasm where codons on mRNA sequence translate into a polypeptide or protein molecules by linking a chain of amino acids by peptide bonds.
