Fill in the blanks a) Three structures found only in plant cells: and e ecium is rigid compared to that of amoeba because of the presence of under its plasma membrane c) Three structures seen prominently in amoeba: d) , and Why do Elode a (plant cells) and onion cells have more consistent shapes than human cells (plant versus animal cells)? Presence of S. Found in plant, animal and/or bacterial cells? a) Nucleus b) Nucleoid c) Chloroplast d) Cell wall (either cellulose or protein-polysaccharide) e) Ribosomes t) Centrioles g) Chlorophyll h) Golgi complex i) SER AND RER j) Central vacuole k) Small vacuoles 6. Fill in the blanks the a) In a spectrophotometer the HIGHER the concentration of the sample, the the transmittance b) Test tube or cuvette containing ONLY the solvent used to dissolve the chemical you which is used to zero the are analyzing (with a spectrophotometer) is called instrument c) Amount of light radiation retained by the sample in a spectrophotometer is called d) Amount of light radiation exiting the sample in a spectrophotometer is called e) The part of the electromagnetic spectrum that has the range of wavelengths 380 to 700 which is expressed as logio(lo/It) which is expressed as (It/lo) x 100 nanometers is called

Explanation / Answer

FIll in the blanks:

1. Structures founnd only in palnt cells are: Sap Vacuole, Plastids, Cell wall.

2. Paramecium has trichocysts under its cell membrane that akes it rigid.

3. Prominent strutures in amoeba are : Pseudopodia, nucleus, cytoplasm and FOod vacuole

4. Plant cells have specific shape because of presence of cell wall.

Strutures found in :

1. Nucleus: ANimal and Plant

2. Nucleoid: Bacteria

3. Chloroplast: Plant

4. Cell wall: Plant and Bacteria

5. Ribosomes: All

6.Centrioles: ANimal cells

7. Chlorophyll: Plant cell, few bacteria

8. Golgi COmplex: Plant and Animal

9. SER and RER: Plant and Animal

10. Central Vacuole: Plant cell

11. Small Vauole: Animal
