Plastids are major organelles found in the cells of plants and algae. Plastids are the site of manufacture and storage of important chemical compounds used by the cell. Plastids often contain pigments used in photosynthesis, and the types of pigments present can change or determine the cell 's color. Plastids are responsible for photosynthesis , storage of products like starch and for the synthesis have the ability to differentiate , or redifferentiate, between these and other forms. All plastids are derived from proplastids (formerly "eoplasts", eo -: dawn, early), which are present in the meristematic regions of the plant. Proplastids and young chloroplasts commonly divide, but more mature chloroplasts also have this capacity. In plants , plastids may differentiate into several forms, depending upon which function they need to play in the cell. Undifferentiated plastids ( proplastids ) may develop into any of the following plastids: [ 1 ] Chloroplasts : fo...

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...
