Berikut adalah ciri-ciri xilem, kecuali

The following are the characteristic of xylem, except

• Sel-sel tersusun memanjang dari hujung ke hujung

  The elongated cells are arranged end to end

• Membentuk akar rambut yang tidak dilapisi kutikel

  Forms root hairs that are not coated with cuticle

• Mempunyai penebalan lignin

  Has lignified walls

Daya antara molekul air dikenali sebagai_________

Force between water molecules is known as__________

• Daya lekatan

  Adhesion force

• Daya lekitan

  Cohesion force

Apakah fungsi pokok kiambang dalam fitoremediasi?

What is the function of the water lettuce in phytoremediation?

• Mengumpulkan logam berat dan menyerap nutrien di loji kumbahan

  Accumulates heavy metals and absorbs nutrients in the waste plant

• Membekalkan oksigen kepada hidupan di dalam tasik

  Provide oxygen to living things in the lake

• Membekalkan makanan kepada hidupan di dalam air

  Supplies food to living things in the water

• Menyerap karbon dioksida di loji kumbahan

  Absorbs carbon dioxide in the waste plant

Bilakah gutasi berlaku?

When does guttation occur?

• Awal pagi

  Early morning

• Tengah hari

  Afternoon

• Petang

  Evening

Apakah itu gutasi?

What is guttation?

• Apabila tumbuhan mati akibat air berlebihan di dalam tisu

  When a plant dies due to excessive water in its tissues

• Apabila tumbuhan layu akibat kekurangan air di dalam tisu

  When a plant wilts due to lack of water in its tissues

• Apabila tumbuhan mengeluarkan air berlebihan secara titisan melalui liang khas pada hujung daun

  When a plant excretes excessive water in droplets through the special pores at the edges of leaves

• Apabila tumbuhan melakukan transpirasi dengan menyingkirkan wap dan titisan air

  When a plant carries out transpiration by discharging both water vapours and droplets

Bagaimanakah air membantu menggerakkan bahan di sepanjang floem?

How does water help in moving substances along the phloem?

• Air melarutkan makanan pejal untuk membolehkannya mengalir dalam floem

  Water dissolves solid food to make it possible to flow in the phloem

• Air memasuki floem untuk mewujudkan tekanan hidrostatik untuk menggerakkan bahan

  Water enters the phloem to create hydrostatic pressure to move substance

• Air hilang secara wap ke atmosfera sehingga mewujudkan ruang untuk bahan bergerak di dalam floem

  Water lose as vapour into atmosphere. creating spaces for substances to move on the phloem

• Tekanan akar memberikan daya sedutan untuk menarik air ke floem

  Root pressure exerts suction force to withdraw water from the phloem

Gutasi membebaskan air yang kaya dengan mineral.

Guttation releases water that is rich in minerals.

• Betul / True

• Salah / False
