GERAK PADA TUMBUHAN( BIOLOGI)

in science •  7 years ago  (edited)

Ohhh ia sahabat ...Ada sedikit ilmu tentang tumbuhan dari saya jelaskan mengenai dengan Tumbuhan, tetapi yang paling pokok @adoelesteem ingin menjelasakan platform ini tentang Gerak Pada Tumbuhan.###

Tumbuhan ialah organismeeukariota multiseluler yang memiliki beberapa kelas antara lain Tumbuhan berbiji terbuka, tanaman bunga,lumut, paku- pakuaan, alga dan lycopodiopsida. Tercatat sekitar 350.000 spesies organisme termasuk di dalamnya, tidak termasuk alga. Dari jumlah tersebut 248.650 jenis merupakan tumbuhan berbunga dan 18.000 jenis tumbuhan lumut.

Gerak tumbuhan terjadi karena tekanan yang mendorong membran sel terhadap dinding sel pada tumbuhan, bakteria, dan fungi, serta pada sel protista yang tidak memiliki dinding sel,(turgon). tumbuh dan pinda karna adanya rangsangan. tidak mempunyanyi sistem saraf pada tumbuhan tetapi dapat memberikan reaksi pada Rangsangan yang menyebabkan adanya bagian dinding sel yang tidak mengalami penebalan. dibagian ini terdapat noktah yang menghubungkan sel satu dengan sel yang lain.

Perbedaan Gerak pada tumbuhan mempunyai 3 macam:Gerak Endonom, higroskopi dan etionom.
  • Gerak endonom yaitu Gerak tumbuhan yang tidak disebabkan rangsangan dari luar seperti pada bawang merah
  • Gerak Hudroskopi yaitu Gerak yang disebabkan oleh kadar air, pecahnya polongan( tumbuhan jarak), gerak membuka kitak spora terjadi pada tumbuhan paku dan gerak membuka serta menutupnya spirangium pada tumbuhan lumut oleh peristom.
  • Gerak Etionom mempunyai tida perbedaan antara lain tropi, taksi dan nasti.
  • Tropi merupakan Gerak bagian tubuh tumbuhan ke arah rangsangan atau menjauhi rangsangan. sepeti gerak tumbuh akar ke pusat bumi,membelot bagian tanaman sebagai akibat persinggungan, gerak akar ke arah tersedisnya air, gerak batang ke arah cahaya, Gerak akar nebuju makaba atau nebjahui racun.
  • Gerak pindah/ Gerah yang pindah tempat dilakukan bersel satu.bagian dari tumbuhan menuju arah datangnya rangsangan. seperti: kloroplas bergerak ke sisi sel yang medapat cahaya matahari.kemotaksin( spermatozoid bergerak menuju sel telur, bateri oerob berkumpul pada tempat yang banyak oksigen).
  • Gerak bagi tubuh terhap rangsangan yang datangnya dari luar dan tidak terpengaruh oleh arah datangnya rangsangan, ini sebut gerak nasti.ini terjadi pada tumbuhan putri malu menutup disaat sentuhan, daun petai cina diwaktu malam bergerak menutup daun majemuk, dan dengan rangsangan cahaya( mekarnya bunga pukul empat pada sore hari.

Ohhh he's a friend ... There's a little science about the plants I explain about with Plants, but the most important thing @adoelesteem wants to explain this platform about Motion On Plants.###

Plants are *** multicellular organisms with multicellular *** which have several classes such as open seed plants, flower plants, mosses, ferns, algae and *** lycopodiopsida. *** It is recorded that about 350,000 *** species *** * ** *** organisms are included, not including algae. Of these 248,650 species are flowering plants and 18,000 species of moss plants.

Plant motion occurs due to pressure that pushes cell membranes against cell walls in plants, bacteria, and fungi, as well as on protist cells that do not have cell walls, (turgons). grow and pinda because of the stimulus. does not sing the nervous system in plants but can react to stimuli that cause the non-thickening cell wall. in this section there is a node that connects one cell with another cell.

Differences Motion in plants has 3 kinds: Endonomic motion, hygroscopy and etionom.
  • Endonomic motion is the motion of plants that are not caused by external stimuli such as onion
  • Hudroscopic motion: Motion caused by moisture content, breakage of legumes (plant spacing), spores open movement of spores occurs in nail plants and the movement of open and close spirangium in moss plants by peristom.
  • Etionom movement has no difference between trophies, taxis and nasties.
  • Tropi is the motion of plant parts to the stimulus or away from stimulation. a movement of roots to the center of the earth, defects part of the plant as a result of intersection, root motion toward water tersedisnya, motion stem towards light, root motion nebuju makaba or nebjahui poison.
  • Moving move / Gerah that moved place done bersel satu.bagian from plant toward the direction of stimulation. such as: the chloroplast moves to the side of the cell in sunlight. The cremotaxin (spermatozoid moves toward the egg cell, the oerobic battery congregates in the oxygenated place).
  • Motion for the body to stimuli that come from outside and not affected by the direction of the arrival of stimulation, this call nasti.ini movement occurs in the embryonic daughter closes at the touch, chinese petai leaves at night move closing compound leaves, and with light stimulation (flowering at four in the afternoon.

Follow my blog There are many other biological sciences I have not had time to discuss on this platform, one of them Transportation on plants and others.

Good science @adoelesteem

he could be

He certainly can
