Stomata merupakan bagian pada daerah epidermis organ tumbuhan yang terdiri dari suatu celah yang dikelilingi oleh sel khusus yang disebut sel penjaga. Stomata sangat penting bagi tumbuhan karena pori stomata merupakan tempat terjadinya pertukaran gas dan air antara atmosfer dengan sistem ruang antar sel yang berada pada jaringan mesofil di bawah epidermis. Praktikum ini bertujuan untuk mengetahui pengaruh turgor terhadap membuka dan menutupnya stomata.
Metode yang digunakan dari praktikum ini adalah membuat sayatan tipis dibagian abaksial daun, kemudian meletaknya pada kaca objek ,diberi 1 tetes air dengan pipet tetes, dan selanjutnya ditutup dengan gelas penutup kemudian diamati dibawah mikroskop apakah stomata dalam keadaan membuka atau menutup lalu dicatat jumlah stomata yang membuka dan menutup. Setelah itu diganti larutan air dengan larutan gula 50% dengan cara meneteskan pada sisi gelas penutup dan menghisapnya dengan tissue lalu diamati jumlah stomata yang membuka dan menutup serta dicatat dan dibandingkan.
Hasil yang didapatkan dari praktikum ini adalah pada pengamatan sayatan epidermis bawah daun Rhoeo discolor dengan tetesan air diapatkan jumlah stomata membuka sebanyak 23 dan menutup sebanyak 6, sementara pada larutan gula 50% ditemukan jumlah stomata yang membuka sebanyak 21 dan menutup sebanyak 8.

TRANSPIRATION Groups: 2Assistant: Choirotin NisaAbstract Stomata are part on the epidermis of a plant organ consisting of a slit which is surrounded by special cells called guard cells. Stomata are very important to plants because the stomata pores is the site of gas exchange between the atmosphere and the water system with spaces between the cells that reside on the network mesofil under the epidermis. This lab course is aimed to know the influence of turgor against opening and closing stomata.Methods used from this lab course is to make a thin incision in abaksial leaf, then meletaknya on the glass object, given a 1 drop of water with the dropper drops, and then covered with a glass cover is then observed under the microscope whether stomata are in a State of open or close and then the number of stomata note opening and closing. After it was replaced with a solution of sugar water solution 50% by way of a shed on the side of the glass cover and suck it with a tissue and then observed a number of stomata open and close as well as recorded and compared.The results obtained from this teaching is the incision on the lower epidermis of the leaf Rhoeo discolor with water droplets diapatkan the number of stomata open as much as 23 and shut down as many as 6, while on a sugar solution 50% found the number of stomata which open up as much as 21 and close as many as 8.Keywords: Stomata, plants, Turgor pressure

Abstract
Stomata part in the epidermis area plant organ comprising a gap surrounded by specialized cells called guard cells. Stomata are very important for the plant because the stomatal pore is the site of gas exchange between the atmosphere and water system with space between cells that are in the mesophyll tissue below the epidermis. Practicum aims to determine the effect of turgor of the opening and closing of stomata.
The method of this lab is to make thin section section abaksial leaves, then meletaknya on the slide, was given one drop of water with a pipette, and then covered with a glass lid is then observed under microscope whether the stomata open or close in a state and then note the number of stomata open and close. After that replaced a water solution with a sugar solution 50% by dripping on the side of the glass cover and suck it with a tissue and then observed the number of stomata opening and closing as well as recorded and compared.
The results obtained from this lab is on the observation incision lower epidermis of leaves Rhoeo discolor with water droplets diapatkan number of stomata open and close as many as 23 by 6, while the 50% sugar solution is found the number of stomata opening and closing as many as 21 8.
