Abstract

This study aims to determine the anatomical structure of the leaves of several macrophytes. This study used a descriptive method to describe and pictures the leaves' anatomical structure. The leaves were sliced crosswise and observed using a binocular microscope with a maximum magnification of 400x. The research was conducted at the Biology Education Laboratory, FKIP Unsri, in March 2021 until now. The parameters observed were complementary to the anatomical tissue structure of the leaves of several macrophyte plants, namely, the composition of the leaf tissue from outside to inside, the number of layers, and cell size. Parameters observed were leaf tissue composition from outside to inside, number of layers, and cell size. The results of the study found that the leaf tissue composition of macrophyte plant leaves was the upper epidermis, palidase parenchyma, aerenchyma, xylem, phloem, collenchyma, parenchyma, and lower epidermis. The number of epidermal layers consists of 1-2 layers, the most layers are found in kale leaves. The number of layers of palisade parenchyma is 1-3 layers, the most layers are in the leaves of apu wood. The number of layers of the lower epidermis is 1-2 layers, the most layers are found in Seroja leaves. Epidermal size ranges from 9.2 µm - 37.9 µm. The size of the palisade parenchyma ranges from 15.4 µm – 88.1 µm. Aerenchyma sizes range from 24.1 µm – 150.3 µm. The size of the lower epidermis ranges from 4.2 µm – 28.7 µm. Xylem size ranges from 17.9 µm – 33 µm. Phloem size 5.5 µm – 13 µm. Parenchyma size ranges from 39.2 µm – 52 µm. Collenchyma size with a size of 40 µm - 80 µm. The results of this study can be used as a learning resource in the form of LKPD (Lembar Kerja Peserta Didik)
