Answer:
Parasite
Explanation:
The tape worm is a parasite because while it benefits its host is harmed.
Answer:
Stomata are the organs present on the stem and leaves of the plant and help in the gaseous exchange and evaporating water present in the aerial parts of the plant. Mainly leaves stomata plays role in gaseous exchange and transpiration which is the evaporation of the aerial water of plants by opening and closing the stomata. Stomata are small pores mostly and normally present under the leaves and regulated by the guard cells, dum bell shaped cells to close or close it.
Other than closing and opening the stomata, stomata density also can affect the rate of gas exchange as well as transpiration. Stomata density is the presence of the numbers of the stomata per unit area. In heat or sunny area the stomata density is higher than the shady or dark area to increase the transpiration in order to cool down the leaves of the plant which prevent the chloroplast proteins to denature.
B
Plant's cuticle is an adaptation on land that prevents the evaporation of water from the plant.
Explanation:
The cuticle is made of lipid polymers impregnated with wax. A thick cuticle covers the epidermis of the leaves and prevents of some plants to prevent the loss of water from the leaves and plants via evaporation. This is especially a significant adaptation to desert plants that need to conserve water because they receive very little annual rainfall in their environment.
