Observation of trichome, stomata, and plant tissue

By -
ayo teman-teman belajar perkembangan tumbuhan! aku masih coba pake bilingual hehe. these are some of our speciment and original my own documents, i didnt grab it from anywhere ! :D

STOMATA
The leaf  epidermis of Sri Rejeki plant ( idk, latin name of its. i just write the name based on my practical handbook) .  it is covered with pores called stomata, part of a stoma complex consisting of a pore surrounded on each side by chloroplast-containing guard cells, and two to four subsidiary cells that lack chloroplasts.The stoma complex regulates the exchange of gases and water vapor between the outside air and the interior of the leaf. The stoma is bounded by two guard cells that differ from the epidermal cells.

TRIKOMA
pada daun  Hibiscus tiliaceus terlihat adanya trikoma. trikoma adalah rambut-rambut yang merupakan turunan/ derivat dari epidermis. pada daun Hibiscus tiliaceus (waru) yang saya amati, trikoma yang terlihat adalah jenis rambut bercabang dan tidak menghasilkan sekret.

Sayatan daun Zea mays.
sayatan daun Durio ziberthinus (durian).

    as we know, chloroplast was containing chlorophyll within it, so in the pic its indicated by green color. The sturcture of its unfortunately unclear, because zoom in just 100x.
