Plant Reproduction and Germination Questions

Multiple choice examples of bryophytes plant kingdom biology

Which of the following plants do not produce seeds?

  1. Ficus and Funaria

  2. Fern and Funaria

  3. Chlamydomonas and Ficus

  4. Punica and Pinus
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ferns and moss are both examples of primitive plants. They are flowerless or seedless plants. Fern and Funaria both are flowerless and seedless.

Mature gymnosperms lack

  1. Seeds

  2. Leaves

  3. Flowers

  4. Vascular tissue

  5. Woody growth
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Gymnosperms are seed-bearing plants but lack the specialized features  of flowering plants. The gymnosperms do not bear flowers hence the seeds are naked i.e these are not enclosed within fruits.

Dominance of angiosperms can be considered due to evolution of

  1. Seed

  2. Fruit

  3. Vascular system

  4. Extensive root system
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Global domination of any species depends on its ability to effectively reproduce. Thus, vascular system or extensive root system, though essential for survival, will not increase the population of the species. Angiosperms developed from gymnosperms or the plants with naked seeds, meaning that seeds evolved before the time of angiosperms. The presence of fruit makes angiosperms reproduce successfully by protecting the seeds and increasing their chances of survival.
So, the correct answer is 'Fruit'.

How do gymnosperms and angioperms differ from each other?

  1. Gymnosperms have naked seed but angiosperms have seed coat

  2. Gymnosperm have leaves but angiosperms do not have leaves

  3. Gymnosperms are seed bearing plant but seed is absent in angiosperm

  4. Both A and B
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary and have a seed coat (usually a fruit), while in gymnosperms flowers or fruits are absent and the seeds are naked. So, they are also called naked seeds. These seeds are present on the surface of scales or leaves.
So, the correct answer is 'Gymnosperms have naked seed but angiosperms have seed coat'.

Angiosperms have dominated the land flora primarily because of their

  1. Domestication by man

  2. Power of adaptability in diverse habitat

  3. Property of producing large number of seeds

  4. Nature of self pollination
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Angiosperms are most diverse and widespread of all plant groups. Their dominance is due to the power of adaptability in diverse habitat. They are well adapted to terrestrial life and occur in diverse habitats like cold tundra to hot tropical and even desert areas. They also thrive well in the aquatic habitat. Therefore, they being the most successful to have dominated the land flora. Hence option B is correct.

Monocotyledonous plants are those in which the seed contains ................ cotyledon/s.

  1. Two

  2. One

  3. Three

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Cotyledons are important parts of the embryo found in a seed. They are the first parts that emerge from the seedling when it germinates. Monocotyledons are plants that have only one cotyledon. They also have other characteristics, such as flower parts in multiples of threes. This means they could have three, six or nine petals, or they could have sepals that make up their flowers. They also have adventitious roots. Garlic is a monocotyledon. Dicotyledons have two cotyledons.
Therefore, the correct answer is option B.

What is true of angiosperms ?

  1. Seeds are naked

  2. They have tracheids only

  3. They are not cryptogams

  4. They lack companion cells.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Angiosperms are phanerogams (seed-bearing plants), not cryptogams (non-seed-bearing plants). They have enclosed seeds, possess both tracheids and vessels, and have companion cells.

Select the correct pair in which one produces naked seeds, whereas the other produces seeds enclosed in maternally derived tissue.

  1. Cyanobacteria and algae

  2. Algae and fungi

  3. Mosses and ferns

  4. Ferns and gymnosperms

  5. Gymnosperms and angiosperms
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Phanerogams, also known as spermatophytes, refer to "all seed plants". Gymnosperms are the seed bearing plants wherein seeds are naked i.e. not enclosed by ovary or fruit. Angiosperms are seed bearing plants wherein seeds are enclosed within ovary or fruit. Since both gymnosperms and angiosperms are seed-bearing plants and therefore are included under phanerogams. Pteridophytes are categorized under cryptogams, not under phanerogams, as they do not form seed or flowers. Thus, the correct answer is option E.
