How are xerophytes and hydrophytes adapted to their habitats?

-
Xerophytes:  thick  waxy  cuticle;  minimize  water  loss;  leaves  are  folded  and  reduced  in  size;  to minimize  stomatal  transpiration;  sunken  stomata;  to  reduce  rate  of  transpiration; thick/succulent  leaves,  side  branches  or  stems;  for  water  storage;  shedding  of  leaves  during  the dry  periods;  to  reduce  surface  area  exposed  for  transpiration;  reversed  stomatal  rhythm; prevent  excessive  loss  of  water;  deep  penetrating  roots;  to  absorb  water  from  deep  below  the surface;  superficial  roots;  to  absorb  surface  water  run-off;  leaves  covered  in  scales/hairs;  to  trap a  moist  layer  of  air;  to  reduce  the  rate  of  transpiration;  drought-resistant  seeds;  that  remain dormant  till  favourable  weather  resumes;  underground  organs  (corms/bulbs);  for  storage  of water  and  reproduction;  most  stomata  located  on  the  lower  leaf  surface;  to  avoid  exposure  to direct  light;  to  reduce  evaporation;  reduced  number  of  stomata;  to  reduce  the  rate  of transpiration;  Hydrophytes:  stomata  on  the  upper  surface  of  leaves;  to  provide  a  large  surface area  for  gaseous  exchange;  and  loss  of  excess  water;  poorly-developed  roots  that  lack  root hairs;  to  reduce/avoid  absorption  of  water;  aerenchyma  tissue  in  leaves,  stems  and  roots;  to store  air;  and  for  buoyancy;  deeply-dissected  leaves;  to  provide  a  large  surface  area  for absorption  of  light;  highly-sensitive;  and  numerous  chloroplasts;  for  photosynthesis;  greatlyreduced  vascular  bundle;  to  avoid  absorption  of  water;  flowers  raised  above  the  water;  to  allow for  pollination;  lack  of  a  cuticle  or  very  thin  cuticle;  for  faster  loss  of  water;  Max.  20  mks

DESCRIBE THE ADAPTATIONS OF THE ILEUM TO ITS FUNCTION (20 MARKS)

-
Has secretory glands/crypts of lieberkuhn which secretes enzymes (maltase/sucrase/lactase/peptidase/lipase to complete digestion of sugars/proteins/lipids. Goblet cells secrete mucus which allows for smooth movement of food and protect wall of ileum from action of digestive enzymes Very long to provide large surface area for absorption. Highly folded/coiled to slow movement of food to allow more time for digestion/absorption/ and to increase surface area for absorption. Has numerous villi which increase surface area for absorption/microvilli which further increase surface area for absorption. Ileum wall/villi have thin epithelium which is only one cell thick to reduce distance over which digested food has to diffuse. Villi are highly vascularised/have a rich network of blood capillaries for rapid transport from small intestines and maintain a steep concentration gradient for rapid absorption. Villi have lacteals for absorption of fatty acids and glycerol Cells of ileum wall h...

Explain how structures of the human ear are adapted to their functions. (20 marks)

Image
The pinna;- is funnel shaped to trap sound waves; cartilaginous to maintain the funnel shape; collects and directs sound waves into the external auditory meatus ear; The external auditory canal; - a tube connected to the pinna that directs sound waves from the pinna to the eardrum lining the auditory canal; has hair that trap foreign particles; The canal contains wax-secreting cells; and hair which traps dust particles; and pathogenic bacteria hence prevent them from getting into the ear; The eardrum; - has a thin tough membrane; that easily vibrates when hit by sound waves; transferring them into vibrations. The ear ossiscles; - they act like a layer and they easily move forward and backward to amplify sound vibrations that hit them; The suspensory ligaments; - suspends the ear ossicles and prevents excessive vibration that would otherwise damage the inner parts of the ear; The eustachian tube - it connects the middle ear with the pharynx; and it equalises air pressure between...

KCSE 2010 Q8. Describe how a finned fish such as Tilapia moves in water. (20 marks)

-
The following describes how  a finned fish such as Tilapia moves in water . v       Water is denser than air. The density of water supports fish and provides a medium in which it swims. v       It has a streamlined body; reducing resistance, thus easily swims in the water. v       The scales overlap pointing backwards allowing water to pass over the fish without obstruction. Mucus is also secreted over the scales reducing friction during movement. v       They have a flexible backbone onto which segments of muscle blocks, myotomes, are attached. The muscles contract and relax bringing about undulating movements. v       The fish have fins that help in steering and balancing fish during swimming. v       The pectoral and pelvic fins are paired. They are used for braking, steering and v   ...
