Yes, the plants with falling leaves can do the process of transpiration in winter, despite of the expelling out of their leaves. The reason is that stomata is also present on other parts of plant body such as stem and branches etc. When leaves fall from plant body during winter, the transpiration takes place from stem and branches of plants body. The rate of transpiration is less due to winter and number of stomata.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
