HOW ARE LEAVES OF MESOPHYTES SUITED TO THEIR FUNCTION? (20MKS)

-
 How are leaves of mesophytes suited to their function.(20mks)
       - Broad / wide / flat lamina; to provide large S.A; for absorption of CO2/sunlight;
            - Thin; to ensure short distance for CO2 to reach photosynthetic cells/palisade/mesophyll;
            - Guard cells/ presence of stomata; for efficient diffusion of CO2 into leaf/ oxygen out of leaf/
gaseous exchange/ water vapour/ transpiration
            - Transparent cuticle/epidermal cells; for penetration of light; into palisade cells/ photosynthetic
cells.
            - Palisade cells contain many chloroplasts; to trap light (for photosynthesis);
            - Chloroplasts have chlorophyll; for trapping light energy;
            - Leaves have veisn; Xylem to conduct water to photosynthetic cells; and phloem to translocate
the photosynthates to other parts of the plant;
            - Air spaces in spongy mesophyll; for gases to circulate/diffuse easily/ for CO2 to diffuse into
palisade cells;
            - Mosaic arrangement of leaves; enables all leaves to trap sunlight;
            - Palisade cells are next to upper epidermis for maximum light absorption (by chloroplasts)

(a) Define digestion It is break down of complex insoluble; v food substance into simple soluble food substances; v 2max (b) Describe the digestion of ugali; Digestion of ugali begins in the mouth;v ugali is chewed by the teeth to increase large surface areav for action of salivary amylase / ptyalin; vThe food mixes with saliva produced by salivary glands;v Saliva contains mucus and enzyme ptyalin. Mucus moistens, softens and lubricates the food;v ptyalin speeds up the conversion of starch to maltose;v ugali is made into bolus in the mouth;v The bolus moves along the oesophagus and prestalsis / by contraction and relaxation of circular and longitudinal muscles into the stomach;v The digestion continues until ugali become acidic since the stomach does not contain carbohydrase / carbohydrate digesting enzymes no digestion of ugali takes place here.v Ugali now

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

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

EXPLAIN HOW ABIOTIC FACTORS AFFECT PLANTS. (20MKS)

 Explain how abiotic factors affect plants. (20mks) Abiotic factors. Wind; -On a windy day rate of transpiration increases since wind carries away water vapour leaving surrounding of leaves with low humidity; the lower the humidity the more the space in the atmosphere for water molecules to occupy. - Wind disperse fruits, seeds and spore; - Wind is an agent of pollination. - Strong winds break branches of trees and may even uproot some trees; Temperature; -Enzymes work best at optimum temperature; changes in temperature hence influence rate of photosynthesis/respiration; and other enzyme controlled biological reactions. -In aquatic environment temperature affects the percent of dissolved gases. Light; - green plants need light for photosynthesis; - some plants need light for flowering; photoperiodism; - some seeds (lettuce) require light for germination; - light affects opening and closing of stomata; which affects transpiration; gaseous exchange and photosynthesis.
