Questions and Answers
  • 1. 

    Teori sel yang menyatakan “omnis celullae celulla” dikemukakan oleh ... .

    • A.

      Robert Hooke

    • B.

      Rudolf Vircow

    • C.

      Felix Dujardin

    • D.

      Johanes Purkinje

    • E.

      Theodor Schwan

    Correct Answer
    B. Rudolf Vircow
    Explanation
    The correct answer is Rudolf Virchow. Rudolf Virchow was a German physician and pathologist who is known for his work in cell theory. He proposed the concept of "omnis cellula e cellula," which means that all cells arise from pre-existing cells. This idea contradicted the prevailing belief at the time that cells could spontaneously generate. Virchow's contribution to cell theory was significant in advancing our understanding of cellular biology.

    Explanation
    The correct answer is 1, 2, 3, 4, 5, 6. This is because all of the listed components - ribosomes, cytoplasm, genetic material, cell membrane, nuclear membrane, and mitochondria - are present in all cells.

  • 3. 

    Plastida memiliki kesamaan dengan mitokondria dalam hal ... .

    • A.

      Penyimpanan karbohidrat, lemak, protein

    • B.

      Mensintesis pigmen hijau, merah, kuning

    • C.

      Ditemukan dalam organisme fotosintetik

    • D.

      Mengandung DNA, RNA, ribosom

    • E.

      Memiliki fungsi seperti mitokondria

    Correct Answer
    C. Ditemukan dalam organisme fotosintetik
    Explanation
    Plastids are organelles found in photosynthetic organisms, such as plants and algae. They are responsible for synthesizing pigments like chlorophyll, which gives plants their green color, as well as other pigments like red and yellow. Plastids also contain their own DNA, RNA, and ribosomes, similar to mitochondria. Therefore, the correct answer is "ditemukan dalam organisme fotosintetik" which means "found in photosynthetic organisms".

    Berikut pernyataan yang tidak benar mengenai lisosom ... .

    • A.

      Penghancuran organel sel yang rusak

    • B.

      Dibungkus satu lapis fosfolipid bilayer

    • C.

      Dibentuk oleh badan golgi

    • D.

      Enzim dalam lisosom disintesis oleh ribosom bebas

    • E.

      Berperan dalam autotomi (pelepasan ekor pada cicak)

    Correct Answer
    D. Enzim dalam lisosom disintesis oleh ribosom bebas
    Explanation
    The incorrect statement about lysosomes is that the enzymes in lysosomes are synthesized by free ribosomes. Lysosomal enzymes are actually synthesized by ribosomes attached to the endoplasmic reticulum (ER), not by free ribosomes. These enzymes are then transported to the Golgi apparatus, where they are packaged into vesicles and eventually fuse with lysosomes. Lysosomes play a crucial role in the breakdown of damaged organelles and cellular waste through the action of these enzymes.

    • A.

      Fosfolipid dan enzim

    • B.

      Fosfolipid dan hormon

    • C.

      Enzim dan hormon

    • D.

      Fosfolipid dan kolesterol

    • E.

      Kolesterol, enzim dan hormon

    Correct Answer
    E. Kolesterol, enzim dan hormon
    Explanation
    The organelle described in the question consists of parallel membranes with flat cavities or tubules and is not granulated. This organelle is responsible for the formation of cholesterol, enzymes, and hormones.

    • E.

      5 dan 7

    Correct Answer
    E. 5 dan 7
    Explanation
    The organelles that are only found in plants are indicated by numbers 5 and 7. Plastids (number 5) are unique to plant cells and are responsible for functions such as photosynthesis and storage of pigments. The cell wall (number 7) is also specific to plant cells and provides support and protection. Therefore, the correct answer is 5 and 7.

    Organel yang berfungsi aktif pada pembelahan sel dan hanya terdapat pada sel hewan adalah ... .

    • A.

      Kromosom

    • B.

      Ribosom

    • C.

      Sentrosom

    • D.

      Lisosom

    • E.

      Autosom

    Correct Answer
    C. Sentrosom
    Explanation
    The correct answer is sentrosom. The sentrosom is an organelle that plays an active role in cell division. It is only found in animal cells and is responsible for organizing the microtubules that form the spindle fibers during mitosis. This helps to ensure the proper separation of chromosomes and the equal distribution of genetic material to the daughter cells.

    • A.

      Hanya pada garam dari konsentrasi tinggi ke konsentrasi rendah

    • B.

      Hanya pada garam dari konsentrasi rendah ke konsentrasi tinggi

    • C.

      Hanya pada molekul organik dari konsentrasi tinggi ke konsentrasi rendah

    • D.

      Hanya pada molekul organik dari konsentrasi rendah ke konsentrasi tinggi

    • E.

      Pada garam mineral maupun molekul organik dari konsentrasi rendah ke konsentrasi tinggi

    Correct Answer
    E. Pada garam mineral maupun molekul organik dari konsentrasi rendah ke konsentrasi tinggi
    Explanation
    Active transport refers to the movement of molecules or ions across a cell membrane against their concentration gradient, from an area of low concentration to an area of high concentration. This process requires the use of energy in the form of ATP. The given answer states that active transport occurs for both mineral salts and organic molecules, and it occurs from low concentration to high concentration, which aligns with the definition of active transport.

    Peristiwa mengkerut atau berkeriputnya sel karena kekurangan air disebut ... .

    • A.

      Lisis

    • B.

      Plasmolisis

    • C.

      Difusi

    • D.

      Osmosis

    • E.

      Krenasi

    Correct Answer
    B. Plasmolisis
    Explanation
    Plasmolisis adalah peristiwa mengkerut atau berkeriputnya sel karena kekurangan air. Ketika sel kehilangan air, tekanan osmotik dalam sel menurun sehingga air keluar dari sel dan menyebabkan sel mengkerut. Plasmolisis terjadi ketika sel tumbuhan berada dalam larutan hipertonik, di mana konsentrasi zat terlarut di luar sel lebih tinggi daripada di dalam sel. Hal ini menyebabkan air keluar dari sel melalui osmosis, menyebabkan sel mengalami kerutan atau keriput.

    Proses sel darah putih yang menangkap kuman penyakit merupakan salah satu contoh dari dari peristiwa ... .

    • A.

      Eksositosis

    • B.

    • C.

      Autofagi

    • D.

      Autolisis

    • E.

      Plasmolisis

    Correct Answer
    B. Endositosis
    Explanation
    Endositosis adalah proses di mana sel memasukkan material dari luar sel ke dalam vesikel yang terbentuk dari membran sel. Dalam konteks ini, proses sel darah putih yang menangkap kuman penyakit melibatkan endositosis karena sel darah putih menangkap kuman dengan membentuk vesikel dari membran selnya untuk mengeksekusi kuman tersebut.
