Theme: Cage and environment

Task 1.Study the factors of differentiation of cages on basic and additional educational literature. Influence of damaging factors on a cage. Cellular death. Necrosis. Аппоптоз.

Prepare a compendium on the topic

Literature: 1, 2, 8 (basic); 26 (additional)

For the receipt of encouraging points a student can execute creative work as writing within the framework СРС and defence of abstract report on СРСП .

Task 1. Check itself

Below different cellular structures are enumerated on the right. Specify, what from the functions or descriptions adopted on the left correspond to each of these structures

1. place of synthesis of albumen 2. provide transferring of cage to the liquid environment or create the current of liquid at the surface of cages 3. hard protective cover of some cages 4. vehicle for the egestion of cellular products 5. photosynthesis 6. large компартмент of vegetable cage, filled by a liquid 7. underlying membrane structure of прокариотических cages 8. regulates the receipt of substances check and from a cage 9. participates in the cellular breathing 10. a cellular membrane contains genetic material of эукариотической cage\u0009of А)

Б) cellular wall В) chloroplust Г) of eye-lash Д) cytoplasmic ретикулум Е) plaits Ж) complex Гольджи З) мезосома И) митохондрия К) kernel Л) ribosome М) vacule

Task 2. Specify what cages each of the structures adopted below is in - in animals, vegetable, прокариотических or in the cages of all organisms.

Structure	Animals cito	Growth cito	Pracriotic cito	Citos of all organisms
1. ribosome
2. The nuclear region
3. The cell wall
4. DNA
5. mitochondrion

Task 3. What it is necessary to use to the biologist at research of coarse-fine of surface of cage :

а) by a light microscope

б) by a transmission electronic microscope

в) by a sweepable electronic microscope

г) by the x-rayed vehicle

Task 4. Two students operate a frog. They all the time moisten the bare internal organs of frog salt solution, and nevertheless after a while these organs begin to shrivel. Glancing in a textbook, students discover that concentration of salt solution it is taken unright: 9% instead of 0,9% (the just the same concentration of salt is supported in the cages of frog) :

а) will explain why during an operation a frog perished;

б) what process did take place here?

did в) participate in this process of molecule are vections?

Task 5. The leadingout of substances from a cage through a complex Гольджи takes place in езультате confluences of membrane sac with a cellular membrane. Content of sac here зливается outside. With what process we have here business:

а)

(мкм is a micrometre, "микро"-одну millionth; нм-нанометр, "нано"-одну milliardth).

3.Cyanogen hydrogen (HCN) and oxide of carbon (CO) are poisons easily penetrating through a cellular membrane. Do you can to suppose some explaining to the circumstance that not a single cage produced adaptations, exclusive a hit in her these substances?

4.Is it possible to expect that there will be more ribosomes in the cages of hair follicle, than in the cage of fatty fabric? Why?

5.Assert that animals, such, what we know them, would not exist, if their cages had walls. How can it be explained?

6.Why is a cage advantageous to keep in a cytoplasm a reserve of albuminous subunits from that assembling of микротрубочек is conducted, but not to build these subunits again every time, when are they needed for formation of mitotical веретина or what - нибудь of other structures?

7.Tobacco smoke represses activity of eye-lashes of epithelium covering overhead respiratory tracts. Why it assists strengthening so-called
