Kuis Pertumbuhan Dan Perkembangan - Quiz

Kuis ini ditujukan untuk siswa kelas 8 SMP. Dalam kuis akan dipaparkan berbagai pertanyaan mengenai materi "Pertumbuhan dan Perkembangan"


Questions and Answers
  • 1. 

    Bertambah besarnya akar dan batang tumbuhan disebabkan oleh . .

    • A.

      Bertambah besar dan tebalnya dinding sel tumbuhan

    • B.

      Bertambah banyaknya sel di dalam jaringan

    • C.

      Bertambah besarnya sel dalam jaringan

    • D.

      Bertambah besarnya rongga sel di dalam jaringan

    Correct Answer
    B. Bertambah banyaknya sel di dalam jaringan
    Explanation
    The increase in the size of roots and stems of plants is caused by the increase in the number of cells in the tissue. As the plant grows, more cells are added to the tissue, leading to an overall increase in size. This is different from the other options, which focus on the size or thickness of individual cells or the size of the cell cavity.

    Perkembangan pada tumbuhan biji dimulai sejak . . .

    • A.

      Sel zigot

    • B.

      Biji ditanam

    • C.

      Biji berkecambah

    • D.

      Tumbuhan ditanam

    Correct Answer
    A. Sel zigot
    Explanation
    The correct answer is "sel zigot". The development of seed plants begins with the fusion of male and female gametes, resulting in the formation of a zygote. This zygote then develops into an embryo, which eventually grows into a seed. Therefore, the development of seed plants starts with the formation of a zygote.

  • 3. 

    Pertumbuhan raksasa, terbentuknya buah yang besar dan tidak berbiji, dipengaruhi oleh hormon . . .

    • A.

      Auksin

    • B.

      Giberelin

    • C.

      Sitokinin

    • D.

      Asam absisat

    Correct Answer
    B. Giberelin
    Explanation
    Giberelin is a plant hormone that plays a crucial role in the growth and development of plants. It promotes cell elongation, which can result in the growth of larger plant structures such as giant fruits. Giberelin also influences the formation of seedless fruits, as it can stimulate fruit development without the need for fertilization or pollination. Therefore, it is likely that giberelin is responsible for the growth of giant fruits and the formation of seedless fruits.

    Pola pertumbuhan dan perkembangan pada makhluk hidup (tumbuhan dan hewan) diatur oleh . . .

    • A.

      Hormon

    • B.

      Makanan

    • C.

      Cahaya

    • D.

      Gen

    Correct Answer
    D. Gen
    Explanation
    The growth and development of living organisms (plants and animals) are regulated by genes. Genes are segments of DNA that contain instructions for the development and functioning of an organism. They determine various traits and characteristics, such as physical appearance and behavior. Genes play a crucial role in controlling the timing and sequence of growth and development processes in living organisms. Hormones, food, and light can also influence growth and development, but they ultimately act upon or interact with genes to produce their effects.

  • 5. 

    Bagian akar yang pertumbuhannya paling cepat adalah

    • A.

      Bagian tengah

    • B.

      Bagian paling ujung

    • C.

      Semua bagian akar

    • D.

      Bagian belakang ujung akar

    Correct Answer
    B. Bagian paling ujung
    Explanation
    The explanation for the correct answer "bagian paling ujung" is that the tip of the root, also known as the root cap, is responsible for the rapid growth of the root. The root cap protects the delicate growing cells behind it and secretes lubricating substances to help the root push through the soil. This constant growth at the tip allows the root to explore and penetrate the soil for water and nutrients efficiently. Therefore, the "bagian paling ujung" or the very end of the root is the part that grows the fastest.

    Perkembangan makhluk hidup adalah proses . . .

    • A.

      Bertambahnya jumlah sel sehingga ukurannya bertambah besar

    • B.

      Berubahnya sel untuk membentuk struktur dan fungsi tertentu

    • C.

      Berubahnya sel dari bentuk kecil menjadi lebih besar

    • D.

      Pertambahan volume dan jumlah sel

    Correct Answer
    B. Berubahnya sel untuk membentuk struktur dan fungsi tertentu
    Explanation
    The correct answer is "berubahnya sel untuk membentuk struktur dan fungsi tertentu." This is because the development of living organisms involves the transformation of cells to form specific structures and functions. As organisms grow and develop, their cells differentiate and specialize to perform specific tasks in different tissues and organs. This process allows for the formation of complex structures and the functioning of various biological processes in living organisms.

    Pertumbuhan pada tumbuhan terjadi pada . . .

    • A.

      Ujung akar yang dewasa

    • B.

      Seluruh bagian tubuh tumbuhan

    • C.

      Jaringan parenkima akar, batang, dan daun

    • D.

      Jaringan meristem ujung tunas dan ujung batang

    Correct Answer
    D. Jaringan meristem ujung tunas dan ujung batang
    Explanation
    The correct answer is "jaringan meristem ujung tunas dan ujung batang". This is because meristem is a type of plant tissue that is responsible for growth and development. The meristem at the tip of the shoot and the tip of the stem are particularly important for plant growth as they continuously produce new cells that elongate and differentiate into various tissues. Therefore, the growth of plants primarily occurs at the meristem of the shoot and stem tips.

    Bayi pada tubuh ibu terletak di dalam. . .

    • A.

      Vagina

    • B.

      Indung telur

    • C.

      Tuba Fallopi

    • D.

      Uterus

    Correct Answer
    D. Uterus
    Explanation
    The correct answer is uterus. The uterus is the organ in a woman's body where a baby develops during pregnancy. It is located inside the body, specifically in the pelvic region. The vagina is the birth canal through which the baby passes during childbirth. The indung telur (ovary) is where eggs are produced, and the tuba Fallopi (Fallopian tube) is the pathway through which the egg travels from the ovary to the uterus. However, it is the uterus where the baby is located during pregnancy.

    Menstruasi pada umumnya terjadi pertama kali pada masa. . .

    • A.

      Anak-anak

    • B.

      Bayi

    • C.

      Pubertas

    • D.

      Dewasa

    Correct Answer
    C. Pubertas
    Explanation
    Menstruasi pada umumnya terjadi pertama kali pada masa pubertas. Pada masa ini, tubuh anak perempuan mengalami perubahan fisik dan hormon yang menyebabkan terjadinya menstruasi. Pubertas biasanya terjadi antara usia 8-13 tahun, tetapi bisa juga terjadi lebih awal atau lebih lambat tergantung pada individu. Selama pubertas, ovarium mulai melepaskan telur dan rahim mempersiapkan diri untuk kemungkinan kehamilan dengan membangun lapisan endometrium. Jika tidak ada kehamilan yang terjadi, lapisan endometrium ini akan dikeluarkan melalui vagina dalam bentuk darah dan jaringan, yang dikenal sebagai menstruasi.

    Cairan dalam rahim untuk melindungi embrio dari guncangan adalah. . .

    • A.

      Cairan amnion

    • B.

      Cairan ekstraseluler

    • C.

      Uterus

    • D.

      Plasenta

    Correct Answer
    A. Cairan amnion
    Explanation
    The correct answer is "cairan amnion." The amniotic fluid is a fluid that surrounds and protects the embryo in the uterus. It acts as a cushion, providing a protective barrier against any external shocks or movements that could potentially harm the developing fetus. It also helps to maintain a stable temperature and provides a medium for the fetus to move and develop properly.
