Among the list of organelle given, which of them are absent in a plant cell but present in animal cells. Cell wall, Cell Membrane, Centrosome, Lysosome, Vacuole, Plastid Correct Answer Centrosome and Lysosome

Concept:

Cell: 

  • The cell is the fundamental unit of life. All the life activities are carried out by cells.
  • The organisms are classified based on the number of cells present in them.
  • Unicellular organisms are single-celled, while multicellular organisms have a large number of cells. 
  • Plants have both a cell wall and a cell membrane (plasma membrane). 
  • ​The cell wall is present in Plant cells while it is absent in animal cells. 

Explanation:​

  • Some of the cell organelles are present in both plant cells and animal cells, while others are unique to just one.
  • Plant and animal cells are different as the plant cell possesses cell walls, plastids, and a large central vacuole.
  • Cell walls, plastids, and a large central vacuole are absent in animal cells.
  • In the plant cell, lysosomes are generally absent.
  • On the other hand, animal cells have centrioles which are absent in almost all plant cells.

​​Thus, centrosome and lysosome are absent in a plant cell but present in animal cells.

Read the passage carefully and choose the best answer to each question out of the four alternatives.
Eight north Indian Ocean countries, namely, Bangladesh, India, the Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand, were asked to contribute names so that a combined list could be compiled. Each country gave eight names and a combined list of 64 names was prepared. This list is currently in use, and all cyclones arising in the north Indian Ocean are named from this list, with one name from each country being used in turn. Almost 38 or 39 names from the list have been used up, but since many cyclones dissipate long before they hit land, their names rarely figure in the papers or other media. The names that people do know about, and remember are, naturally, those that were most destructive ones, or very recent. Aila, in 2009 is remembered with a shudder for the enormous destruction it caused in West Bengal and Bangladesh; Phaillin, also for the damage it caused when it hit the Odisha coast in 2013. Two harmless cyclones, which also might remain in peoples memory, are the more recent ones of 2014 — Hudhud, which threatened the east coast of India and Nilofar, which was expected to, but did not, devastate the western coast. The names in the cyclone list are usually words one associates with storms; words which mean water or wind or lightning in various national languages. Sometimes they are names of other things — birds or flowers or precious stones. The name Aila, contributed by the Maldives means fire, the name Phaillin from Thailand means sapphire, the name Hudhud from Oman is the name of a bird, probably the hoopoe, and the name Nilofar, given by Pakistan, is the Urdu name of the lotus or water lily. The eight names suggested by India, and which are in the list of 64, are Agni, Akaash, Bijli, Jal, Leher, Megh, Sagar and Vayu, meaning in that order, fire, sky, lightning, water, wave, cloud, sea and wind. Five of these names (that is, up to Leher) have been used so far.
