Cotyledon is also known as

  1. Seed leaves

  2. Endosperm

  3. Embryo

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The cotyledons are referred to as seed leaves. It is because they act as the leaves of the seed during the process of germination. This in the sense that, as the leaves of plants provide food for the plants, so does the cotyledons provide food for the germinating plant. This is possible because the cotyledons store food necessary used during this process. So, the correct option is 'Seed leaves'.

Which character of pteridophytes is not similar to bryophytes?

  1. Water requirement for fertilization

  2. Dependence of sporophyte on gametophyte

  3. Heterospory

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • Bryophytes are known as the amphibians of plant kingdom because they need water for fertilisation. The sperms of bryophytes are flagellated and reach the eggs by means of swimming in water. On the other hand, pteridophytes do not need water for fertilisation.
  • Bryophytes have gametophyte as dominant phase of life on which sporophyte is dependent whereas Pteridophytes have sporophyte as dominant phase but sporophyte is not dependent on gametophyte.
  • Heterospory is the formation of two types of spores which are different in size i.e. large spores and small spores. Large spores are called megaspores while small spores are called microspores. Spores are formed by the sporophyte both in bryophytes and pteridophytes.
Hence, option A is defines a character which is not same in bryophytes and pteridophytes.
So, the correct answer is 'Water requirement for fertilization'.

  2. Order

  3. Family

  4. Class
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Species represents a distinct group of the population that really or most likely breed from close animals. This taxonomic class is segregated from other classes through the method of reproduction. It bears minimal taxonomic traits.
It includes individuals that inherit basic similarities.It can be differentiated from other closely connected species because of idiosyncratic morphological characteristics. Option A is the answer

Midrib is present in leaves of

  1. Monocots

  2. Bryophytes

  3. Pteridophytes

  4. None of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
option (d) is correct.
Explanation- It is in this layer that photosynthesis occurs. it contains a prominent midrib at the centre of the leaf blade which is the main vein. From this midrib arise branches called veins. they are of different types depending upon the type of edges, the pattern of the veins and the number of blades per leaf.
