Fsc part 2 online preparation for biology chapter 15 (Homeostasis)

Question # 1

Described the structure of a flame cell.

Ans 1: It is a complete eukaryotic cell.It has a unucles, other cell organelles and a cavity where the waste products are collected.Each flame cell has a tuft of cilia, whose beating propel interstitial fluid into the tubular system

Question # 2

Write a short note on kidney transplantation.

Ans 1: Dialysis is used temporerily.In high degree renal failure also called uremia or end stage renal disease.The dialysis is replaced by surgical transplantation of kidney of a matching donor kidney is the only option left as the permanent treatment. Kidney Should be of nearest to avoid tissue rejection.

Question # 3

Differentiate between hydrophytes and mesophytes.

Ans 1: Hydrophytes: Hydrophytes are the plant which grow in aquatic environment (abundant water),they have large leave surface area and stomata are present on the upper side of leaves, they have high rate of transpiration. E.g., Water lilli, Wolfia, Pistia etc.
Ans 2: Mesophytes: These are the plants which grow on land where moderate water is available: they open their stomata during flooding and close stomata during drought.For Example: rose and mango.

Question # 4

What is vasa recta?

Ans 1: In juxtamedullary nephrons additional capillaries extend down to from a loop of vessels called vasa reata.

Question # 5

What is renal failure?

Ans 1: When kidneys perform no more function and cannot filter blood to produce nitrogenous waste, this is called renal failure or uemia.

Question # 6

Differentiate between hypotonic and hypertonic solution.

Ans 1: Hypotonic Solution: Dilutes solution compared to the cell concentration is called hypotonic solution.
Ans 2: Hypertonic Solution: The more concentrated external environment as compared to cell is called hypertonic solution.

Question # 7

Give adaptation of marine fish for its survival in cold environment.

Ans 1: These fishes have a thick layer of insulting fat called blubber, which prevent excess heat loss from the body.

Question # 8

Define Excretion.

Ans 1: Removal of waste products (especially nitrogenous wastes) from the body is called excretion.

Question # 9

Define excretophore./what are excretophores %why?

Ans 1: Leaves are called excretophore because they collect nitrogenous waste from different plant parts and they store temporarily, at autumn season plants shed their leaves and wastes are removed from plant body.

Question # 10

Define dialysis.Give its types.

Ans 1: When the kidneys of a patient are failed then nitrogenous wastes are removed by filtering blood through dialysis.Dialyzing machine is called artificial kidney machine.
It has two types:
1. Peritoneal dialysis
2. Hemodialysis
