  12. Membranous sac that contains digestive enzymes
  13. Separates nuclear contents from cytoplasm
  14. Spherical organelle that contains chromatin and nucleolus

The Correct Answer and Explanation is :

Here is the correct matching between the components in Column A and the descriptions in Column B:

Column A – Column B:

  • a. Chromatin → 1. Loosely coiled fibers containing protein and DNA within nucleus
  • b. Cytoplasm → 8. Occupies space between plasma membrane and nucleus
  • c. Endoplasmic reticulum → 7. Composed of membrane-bound canals for tubular transport throughout the cytoplasm
  • d. Golgi apparatus (complex) → 9. Flattened, membranous sacs that modify and package a secretion
  • e. Lysosome → 10. Membranous sac that contains digestive enzymes
  • f. Microtubule → 6. Part of the cytoskeleton involved in cellular movement
  • g. Mitochondrion → 2. Location of ATP production for cellular energy
  • h. Nuclear envelope → 11. Separates nuclear contents from cytoplasm
  • i. Nucleolus → 5. Dense body of RNA and protein within the nucleus
  • j. Nucleus → 12. Spherical organelle that contains chromatin and nucleolus
  • k. Ribosome → 3. Small RNA-containing particles for the synthesis of proteins
  • l. Vesicle → 4. Membranous sac formed by the pinching off of pieces of plasma membrane

Explanation:

  1. Chromatin consists of a combination of DNA and proteins found in the nucleus. In its uncondensed form, it is loosely coiled and forms a network of fibers, which is crucial for the function of the cell’s genetic material.
  2. The cytoplasm is the gel-like substance between the plasma membrane and the nucleus. It contains all the cell’s organelles except the nucleus.
  3. The endoplasmic reticulum (ER) is a network of tubules and sacs that are involved in the transport of materials throughout the cell. The rough ER has ribosomes and synthesizes proteins, while the smooth ER is involved in lipid synthesis.
  4. The Golgi apparatus (complex) consists of flattened sacs that modify, package, and distribute proteins and lipids produced by the endoplasmic reticulum.
  5. Lysosomes contain digestive enzymes that break down waste materials, cellular debris, and foreign substances within the cell.
  6. Microtubules are components of the cytoskeleton that help the cell maintain its shape and facilitate cellular movement, including the movement of organelles and chromosomes.
  7. The mitochondrion is the power generator of the cell. It converts nutrients into energy in the form of ATP, which the cell uses for various processes.
  8. The nuclear envelope is a double membrane structure that separates the contents of the nucleus from the cytoplasm, providing protection and regulating the exchange of materials.
  9. The nucleolus is a dense structure within the nucleus that is involved in producing ribosomal RNA and assembling ribosome subunits.
  10. The nucleus is the control center of the cell, housing the genetic material (chromatin) and the nucleolus.
  11. Ribosomes are small, non-membranous structures responsible for protein synthesis within the cell.
  12. Vesicles are small, membrane-bound sacs that transport substances within or outside the cell.

Now, I will generate an image of the cell with its components labeled.

Here is the detailed diagram of an animal cell with key cellular components labeled, showing each organelle and its location. Let me know if you’d like any more information or if you need further clarification!
