Bob is investigating two leaf samples. He views a leaf sample taken from a desert plant under the microscope and notices that the stomata are all closed. He then views a leaf sample taken
from the rainforest and notices that most of the stomata are open. What is the most likely
explanation for the differences that Bob sees between the two leaf samples?
Due to the differences in climate, desert plants need to conserve more water than rainforest plants.
Due to the diffences in climate, desert plants do not need to grow as quickly as rainforest plants.
Due to the differences in climate, desert plants do not need to exchange gases as efficiently as rainforest
plants
O Due to the differences in climate, desert plants do not need to reproduce as often as rainforest plants.

Due to the differences in climate, desert plants need to conserve more water than rainforest plants.

Explanation:

Plants possess on their leaves certain pores or structures called STOMATA (singular- stoma). The stomata in their leaves primarily serves for the exchange of gas i.e take in CO2 and expel 02 gas. These cases are used (CO2) and released (O2) during photosynthesis. However, stomata is the passage of water in plants, a process called TRANSPIRATION.

According to this question, Bob is investigated two leaf samples using a microscope. He notices that the stomata of the plants from the desert are all closed while that of the rainforest are open.

- The desert region has a kind of climate where the rainfall is extremely low unlike the rainforest, which has an extremely high yearly rainfall. Due to this climate difference, desert plants need to conserve more water than rainforest plants. Hence, their stomata, which allows passage of water out of the plant, is usually closed

the statement is true
