IrinaVladis [17]

A type of glycocalyx called the slime layer is loosely attached to the bacterial cell and protects it from dehydration and loss of nutrients .

<h3>What is glycocalyx ?</h3>

The glycocalyx is a thick outer covering of the plasma membrane .it is of stands of sugars and proteins bound together ,the result is a thick ,sticky layer that helps cells stay put in environments with lots of physical stress .it is a glycoprotein and glycolipid covering that surrounds the cell membranes of bacteria ,epithelial cells and other cells .

Glycocalyx in humans : it is important to both vascular function and the digestive system . your blood vessels actually tiny tubes made of cells .the cells on the very inside of the tube are called endothelial cells and have to withstand the stress of blood flowing over them constantly. endothelial cells produce a glycocalyx which helps leukocytes and thrombocytes stick to blood vessel walls.it is the protective layer of the endothelial cells found in the lumen side of the vessels .

Glycocalyx in bacteria : most of the bacteria produce glycocalyx but some are expert .these expert bacteria make a very thick glycocalyx that helps them to adhere to each other and surfaces in extreme environments .bacteria use the glycocalyx to make thick films of bacteria in nature as well ,called a biofilm .

Clara is a vegan and she does not drink milk, a food advertised as a best source of calcium. But she is not worried too much sin
marysya [2.9K]

Explanation:

%DV label= 27%

1 cup of cooked collared greens= aprx 266.60 mg of Calcium

Assuming Clara is...

  • a teen, her required adequate intake (RAI)=  1300 mg/ day
  • an adult, her RAI= 1000 mg/day

For teenaged Clara

∵27 % DV= 270mg

% daily Calcium=  \frac{270}{1300}  * 100= = 20.8 ≈ 21%

=0.21

<u>21% of her daily calcium needs is in a cup of cooked collard greens.</u>

Calcium is an essential mineral required by the human body, it is involved in cell signalling, muscular function and homeostasis. Along with fats, fiber, vitamin A and C and iron, calcium makes up part of a recommended daily intake target or DV- these are integral to a balanced diet.

State two ways in which palisade tissue is a dapted for thotosynthesis?<br>​
olga nikolaevna [1]
Palisade mesophyll cells are closely packed to absorb the maximum light. They are at right angles to the surface of leaf to reduce the number of cross walls. Large vacuole pushes chloroplasts to the edge of a cell. Chloroplasts at edge enable short diffusion path for carbon dioxide and to absorb maximum light.
