Which organism transforms complex organic compounds back into simple inorganic compound?

  1. Saprotrophs

  2. Consumers

  3. Producers

  4. Herbivores

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Saprotrophs, such as bacteria and fungi, are decomposers that break down organic matter from dead organisms into simpler inorganic substances. This process recycles nutrients back into the ecosystem.

Indian pipe plant are example of ______

  1. Autotrophic plant.

  2. Angiosperm

  3. Saprophyte

  4. Parasite

C Correct answer
Explanation

Saprophytes are the class of organism that have saprophytic mode of nutrition. They feed on dead living organism. Indian pipe plant :- it is not a fungus, it just looks like one. It is actually a flowering plant, and it is a member of the blueberry family.

When two gametes come together to form sporophyte, the sporphyte dies due to

  1. Genetic imcompatibility

  2. Hybrid sterility

  3. Sporophytic inviability

  4. Sporophytic breakdown

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Sporophytic inviability refers to the failure of a zygote or embryo to develop into a viable sporophyte due to genetic or developmental incompatibility. The other terms are not standard biological classifications for this specific failure.

Nepenthes belongs to the category of

  1. Primary consumer

  2. Producer

  3. Secondary consumer

  4. Both B and C

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Nepenthes belongs to the category of producer and secondary consumer. It is also called as topical pitcher plant. It belongs to category of producer as it can synthesize its own food using solar energy. It belongs to secondary consumer because it is a carnivorous plant. It  preys the insects and derives nitrogen from it. Thus, the correct answer is 'Both B and C.'

Multiple choice botany life processes in living organisms- part 1 introduction to flower pre fertilization - plants modes of reproduction

Site of meiosis in angiosperms is

  1. Meristem

  2. Spore mother cell

  3. Roots

  4. Petals or pollens

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Site of meiosis in Angiosperms is the spore mother cell. 

A typical anther contains four microsporangia. The microsporangia form sacs or pockets in the anther. The two separate locules on each side of an anther may fuse into a single locule. Each microsporangium is lined with a nutritive tissue layer called the tapetum and initially contains diploid pollen mother cells. These undergo meiosis to form haploid spores. The spores may remain attached to each other in a tetrad or separate after meiosis.

In plants, meiosis can be observed in 

  1. Root tip

  2. Leaf primordia

  3. Sporangia

  4. Spores

C Correct answer
Explanation

In plants, meiosis can be observed in sporangia. A microsporangium is the part of plant is suitable for the study of meiosis. A typical anther contains four microsporangia. The microsporangia form sacs or locules in the anther. The two separate locules on each side of an anther may fuse into a single locule. Each microsporangium is lined with a nutritive tissue layer called the tapetum and initially contains diploid pollen mother cells. These undergo meiosis to form haploid spores.

Which of the following is the site of meiosis in higher plants?

  1. Growth cells

  2. Root tip cell

  3. Stomatal cell

  4. Spore mother cell

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The site of meiosis in higher plants is the spore mother cell.  In land plants and some algae, there is an alternation of generations such that meiosis in the diploid sporophyte generation produces haploid spores. These spores multiply by mitosis, developing into the haploid gametophyte generation, which then gives rise to gametes directly. In both animals and plants, the final stage is for the gametes to fuse, restoring the original number of chromosomes.
