Step 1 As transpiration is the loss of water from the aerial parts of the plants, antitranspirants are substances when applied to plant, reduce the rate of transpiration without causing any adverse effect on the life processes of plants. Foliage have several structures that prevent water loss, protect plants as a whole, aids in gaseous exchange.Step 2 Plants living in environments where water is in short supply needs to conserve water. There are numerous ways by which plants conserve water with the help of foliage: Plants have needle-like leaves. This cuts down the surface area of the leaf and thereby cuts down the number of stomata on each leave. Plants have spines replaced with leaves to limit the loss of water in a hot climate. The epidermis is one cell layer thick and consists of upper and lower epidermis that aids in the regulation of gaseous exchange, but plants growing in hot or cold conditions, may have their epidermis several layers thick to protect against excessive water loss due to transpiration. Leaf trichomes are small hairs on the leaves modulating leaf traits, the density of trichomes on leaves acts as a mechanism to reduce water loss by blocking airflow across the leaf surface. Thus, the option with-all of the above characteristics are used to conserve water is the correct answer.
