a) a small organelle
b) a small loop of dna
These are micro body which is found virtually in all the eukaryotic cells. They are involved in the catabolism of long chain and short chain fatty acid.
They generate the highly reactive oxygen species and it is broken down here only.These molecules are hydrogen peroxide and they are converted into water molecules.
This organelle is known as peroxisomes.
1d; 2b; 3g; 4e; 5a; 6f
1d: cell membrane is found in both eukaryotes and prokaryotes . It is selectively permeable to molecules and regulates transport of material across the membrane.
2b: capsule forms the outermost layer of some bacteria and confers resistance to attack by the immune system.
3g: nucleoid contains the genome of bacteria and unlike the nucleus it is not surrounded by a membrane.
4e: plasmids occur naturally in bacterial cells as a means for antibiotic resistance and defense against toxins and other bacterial species.
5a: ribosomes are found in both eukaryotes and prokaryotes, although structurally different they act as a site for protein synthesis.
6f: flagella is primarily used for locomotion.
D more active metabolically
As a result of their surface area to volume ratio, smaller living cells are more active metabolically as transport through the cell organelles occur faster
I believe it is centrioles.
i took this test and i chose B. a small loop of DNA and i got it right
Letter A, Electron microscope
The electron microscope is used to visualize high-resolution images of biological specimens. It used to see in detail very small cells, organelles, cells tissues, molecular complexes, etc. The ribosome is a complex molecule made of proteins where the translation of proteins is made, it is very small that can be seen in detail using the electron microscope.
Plasmids resembles the shape and size of a small circular DNA strand that lies with in the the cytoplasm of a bacterium or protozoan. Thus option B is the correct answer
They are different from normal cell's chromosomal DNA and usually exists naturally in bacterial cells and some Eukaryotas. They have the ability to replicate independently of the chromosome and thus are mainly used in laboratory for experiments involving gene manipulation
Hence, option B is correct
Ribosomes are the smallest so they're the answer.
i believe your answer would be c.. : )
