Answer:
to test for liberation of O₂ in the light.
Explanation:
Answer:
it becames turgid
Explanation:
Plant cells have plasma membrane and rigid cellulose cell wall. When the cell is placed or immersed in distilled water, the water is absorbed by osmosis. As the cell becomes turgid, the cell wall creates an inward force i.e wall pressure that prevents the cell from bursting.
Answer:
Molecules that are not soluble in water are fats and non-polar molecules . During their digestion and absorption in the small snall intestine, fats are packaged into hydrophilic form.
Explanation:
This explains the digestion of fats in the small intestine. This takes place in the illeum.( the longest part of 3.5 m) Bile salts from the liver, emulsified these fats, covering then with layers,while enzymatic action by lipase, from the pancreases, completes the process.
These fatty substance formed are called Micelles.In the intestinal cells, the micelles are covered by protein and lipids to aid transport in water medium of the intestine.A this sage they are called (lipoprotein).
They are absorbed in the lacteal- the lymphatic capillaries , unlike protein and CHO which are absorbed directly in the blood stream.I
They are finally absorbed into the blood stream via the lymphatic vessels.
