The correct answer is detailed structure inside the cell.

The main feature of compound light microscope is the light source which helps to see the objects more clearly. This microscope is usually used to see the detailed structure inside the cell. The cell organelles are clearly visible that are very minute in size and cannot be seen through naked eyes. This allows us to study the features of the cell more accurately and precisely.

The work done by dr. rose ann cattolico and her assistants at the university of washington involves _______.
sergeinik [125]
The question above is incomplete, the options attached to the question are as follows:
A. extracting chlorophyll from algae to learn how these organisms gain energy from light.
 B. engineering vehicles that use algae for fuel.
C. growing algae under different conditions and measuring their lipid production.
 D. engineering algae to photosynthesize at higher rates.

ANSWER
The correct option is C.
 Dr. Rose and her assistants set out to carry out scientific investigation that will identify living organisms that can grow rapidly and that will produce high quality lipids at the same time. The team had hypothesized that this type of organisms will be good candidates for production of bio fuels. The group concentrated on working with algae; these were grown under different conditions and their lipid contents were assessed. Their work has led to identification of many algae species as potential sources of bio fuel. <span /><span>

Match the call structure with the best description. Each cell structure matches with exactly one description.
Makovka662 [10]

Answer:

Please find the cell structure with their best descriptions below

Explanation:

1. Capsule: Capsules are one of the Glycocalyx that firmly attaches to the cell surface and helps the cell avoid phagocytosis.

2. Slime layer: Slime layer is the other Glycocalyx that is loosely attached to the cell surface and helps the cell prevent dessication.

3. Flagella: The flagella is a long whip-like cell structure found in bacteria and some protists and principally used for moving.

4. Conjugation pilus: Conjugation pilus is a cell structure in bacteria that is used to transfer DNA to another bacteria cell.

5. Fimbriae: Fimbriae is a short, bristle-like protein that project from cell surface and help cells attach to surfaces of other cells.

6. Cell wall: Cell wall is a cellular structure found in plant cell and bacteria cells, whose function is to protect cells from harsh conditions and helps maintain cell shape.

7. Cell membrane: The cell membrane controls passage of substances into and out of the cell.

8. Cytoplasm: The cytoplasm is a gelatinous material found inside the cell.

9. Inclusions: Inclusions are structures in cells that formed from the deposits of nutrients.

10. Endospores: Endospores are structures that protect bacterial genome in a dormant state under adverse environmental condition.

11. Ribosomes: Ribosomes are organelles in a cell that makes polypeptide (protein).

12. Mycolic acid: Mycolic acid is a waxy molecule (long fatty acid chain) that is found in some gram positive bacteria and associated with their cell wall.

13. Nucleoid: A nucleoid is a region in prokaryotic cell where chromosomal DNA and DNA-associated proteins are concentrated.

14. Pili: Pili is similar to the Fimbriae but longer and contain less numerous protein appendages than fimbriae used in attachment.
