Slime moulds are

Detailed Solution: Question 1

Slime moulds are saprophytic protists. The body moves along decaying twigs and leaves engulfing organic material. Under suitable conditions, they form an aggregation called plasmodium which may grow and spread over several feet.

How do slime moulds typically behave under favorable conditions?

Detailed Solution: Question 2

Slime moulds exhibit interesting behaviours when conditions are favourable:

  • They move along decaying twigs and leaves, engulfing organic material.
  • They can form a structure called plasmodium, which can grow and spread significantly.
  • In unfavourable conditions, plasmodium develops into fruiting bodies that produce spores.
  • The spores are resilient and can survive for many years, even in harsh environments.
  • These spores are dispersed by air currents.
     

Topic in NCERT: Slime Moulds

Line in NCERT: Slime moulds are saprophytic protists. The body moves along decaying twigs and leaves engulfing organic material. Under suitable conditions, they form an aggregation called plasmodium which may grow and spread over several feet. During unfavourable conditions, the plasmodium differentiates and forms fruiting bodies bearing spores at their tips. The spores possess true walls. They are extremely resistant and survive for many years, even under adverse conditions. The spores are dispersed by air currents.

    Detailed Solution: Question 6

    diatoms have left behind large amount of cell wall deposits in their habitat; this accumulation over billions of years is referred to as ‘diatomaceous earth’. Being gritty this soil is used in polishing, filtration of oils and syrups. Diatoms are the chief ‘producers’ in the oceans.

    Match each item in Column I with one in Column II and select your answer from the codes given below:

    Detailed Solution: Question 7

    • Diatoms (A) have a cell wall that is embedded with silica, giving them a rigid structure. This makes the correct match A-b.

    • Dinoflagellates (B) have cellulose plates in their cell walls, which are characteristic of this group, often leading to their description as having "armored" cells. This makes the correct match B-d.

    • Euglenoids (C) do not have a traditional cell wall; instead, they have a flexible outer layer known as a pellicle, which is a protein-rich layer. This makes the correct match C-a.

    • Slime moulds (D) are known for producing spores that have true walls, used in their reproductive cycle. This makes the correct match D-c.

    Protista differs from monera in having

    Detailed Solution: Question 8

    - Correct Answer: D
    - Explanation:
    - Protista is a kingdom of eukaryotic organisms, which means they have a , cell body contains a well defined nucleus( presence of nuclear membrane) and other membrane-bound organelles
    - Monera, on the other hand, are prokaryotic organisms lacking a true nucleus and nuclear membrane.

    Otherwise both have cell wall, unicellular and mode of nutrition is same.

    The cell wall is composed of two thin overlapping shells which fit together like a soap case, in

    Detailed Solution: Question 9

    In diatoms the cell walls form two thin overlapping shells, which fit together as in a soap box. The walls are embedded with silica and thus the walls are indestructible. Thus, diatoms have left behind large amount of cell wall deposits in their habitat; this accumulation over billions of years is referred to as ‘diatomaceous earth’. Being gritty this soil is used in polishing, filtration of oils and syrups. Diatoms are the chief ‘producers’ in the oceans

    What would you identify it as?

    Detailed Solution: Question 13

    Dinoflagellates appear yellow, green, brown, blue or red depending on the main pigments present in their cells. The cell wall has stiff cellulose plates on the outer surface. Most of them have two flagella; one lies longitudinally and the other transversely in a furrow between the wall plates

    Which of the following statements about Euglena is correct?

    Detailed Solution: Question 14

    First option is correct 

    Instead of a cell wall, euglenoids they have a protein rich layer called pellicle which makes their body flexible.

    option 2 is incorrect because Though they are photosynthetic in the presence of sunlight, when deprived of sunlight they behave like heterotrophs by predating on other smaller organisms.

     Option 3 is incorrect because Interestingly, the pigments of euglenoids are identical to those present in higher plants. 

    option 4 is incorrect beacuse Majority of them are fresh water organisms found in stagnant water.

    Assertion (A): All protozoans are heterotrophs and primarily live as predators or parasites.

    Reason (R): Protozoans possess chloroplasts that allow them to perform photosynthesis.

    Detailed Solution: Question 15

    - The Assertion (A) is correct because it accurately describes the nutritional habits of protozoans as heterotrophs that mostly function as predators or parasites.

    - The Reason (R) is false since protozoans do not possess chloroplasts and cannot perform photosynthesis; they are dependent on other organisms for nutrition.

    - Therefore, the Reason is not the correct explanation of the Assertion. Since the Assertion is true and the Reason is false, the correct option is Option C.
