Solution

which type of soil would you expect to have the most available water?

Sand

Silty clay

Loam

Clay

Answer:

Among the above four types of soil, Silty clay has maximum water holding capacity.

Water holding capacity designates the ability of a soil to hold water. It is useful information for irrigation scheduling, crop selection, groundwater contamination considerations, estimating runoff and determining when plants will become stressed. Water holding capacity varies by soil texture.

If the temperature of a plant is 18C and the ambient temperature is 14C, which process will result in a net input of heat from the air to the plant ?

Conduction

Convection

Evaporation

None of the above

Answer: None of the above

The temperature of any plant organ depends on the balance between incoming energy and energy loss. Various biophysical mechanisms are available to plants, through manipulation of the energy balance terms, for temperature regulation. For example, enhanced evaporation can help cool leaves in hot environments, whereas maximising absorption of sunlight can raise the temperature in cold environments.
