Answer:
stomata is a guard cell found in the leaf after the palisade mesophyll tissue
it responsible for transpiration
Step-by-step explanation:
Answer:
a) Stomata serve a very important function to plants, allowing them to use photosynthesis to make energy for survival. However, water loss, also known as transpiration, occurs when the stomata are open and gases are exchanging, which can be harmful to plants.
b) Tooth exploitation result when plaque forms on the surface of a tooth and converts the free sugars (all sugars added to foods by the manufacturer, cook, or consumer, plus sugars naturally present in honey, syrups, and fruit juices) contained in foods and drinks into acids that destroy the tooth over time.
c) Reflex arc - the nerve pathway involved in a reflex action, including at its simplest a sensory nerve and a motor nerve with a synapse between. ... The path through which the stimulus travels is called reflex arc. (The diagram is given below in the attachment) Nerve Impulses flow in one direction only.
