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

The book 'Structure and Reproduction of the Algae' describing taxonomy of algae is written by Felix Eugen Fritsch FRS. He was a British biologist. He gave very comprehensive and authoritative account of classification of algae based on a variety of characters as pigmentation, stored food matter, habit, habitat and method of reproduction. 

Multiple choice biology plant taxonomy classification of kingdom plantae features of plant and animal kingdom plant classification
Plant X has undifferentiated plant body.
Plant Y is a seedless vascular plant that is differentiated into stem, roots and leaves.
Plant Z is a plant bearing seeds.
Select the correct statement regarding X, Y, and Z.

  1. X can be an Angiosperm.

  2. Y can be Gymnosperm.

  3. Y can be a Thallophyte.

  4. Z can be angiosperms or Gymnosperms.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

X can be thallophytes which have an undifferentiated plant body, that is, in the form of an undivided thallus. Algae are thallophytes belonging to kingdom Plantae. Fungi belong to kingdom Fungi. Y can be pteridophytes which are seedless vascular plants and differentiated into true stern, leaves and roots. Bryophytes are simple land plants with no true roots. The plant body is thallose or foliose. Z can be angiosperms or gymnosperms since both of them have seeds. However, angiosperms have seeds covered by fruit whereas gymnosperms have naked seeds. So, the correct answer is option D. 

Multiple choice biology plant taxonomy classification of kingdom plantae features of plant and animal kingdom plant classification

Kingdom plantae shows two phases of life, gametophytic and

  1. Autotrophic

  2. Sporophytic

  3. Saprophytic

  4. Geophytic
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bryophytes are the plants in which the life cycle has two phases gametophytic and sporophytic, alternating to each other. This phenomenon is called alternation of generation. Gametophytic phase is haploid, autotrophic, gametes(male and female) formative and responsible for the sexual reproduction. Sporophytic phase is the subsidiary phase which is diploid, heterotrophic and spore formative and responsible for the asexual reproduction. For example, Riccia, Funaria.

So, the correct answer is option B.

Choose the correct answers from the alternatives given.
Into which of the following kingdoms would you place a multicellular land organism that carries on photosynthesis

  1. Animalia

  2. Plantae

  3. Fungi

  4. Protista
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Kingdom Plantae includes all eukaryotic chlorophyllous autotrophic organisms. A few members are partially heterotrophic such as insectivorous plant or parasites. bladderwort and venus fly trap are examples of insectivorous plants and Cuscuta is a parasite. 

Hence, the correct answer is 'Plantae'.

Multiple choice biology plant taxonomy classification of kingdom plantae features of plant and animal kingdom plant classification

Choose the correct answers from the alternatives given.
Plants are believed to have evolved from the

  1. euglenophytes, because they have chlorophyll a and b

  2. dinoflagellates, because they have similar storage products and cellulosic cell walls

  3. chlorophytes, because of similarities in chloroplasts and accessory pigments

  4. rhodophytes, because they have carotenoids and use floridean starch as a storage product
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Chlorophyta is the green algae that contain the pigment chlorophyll A and chlorophyll b in the well-defined chloroplast. Plants are considered to have evolved from Chlorophyta because plants are green in color and they have chlorophyll A and chlorophyll b pigment just like the Chlorophyta family.

There is well-defined chloroplast which stores this pigment in plants.
So, the correct option is 'chlorophytes, because of similarities in chloroplasts and accessory pigments'

Multiple choice natural vegetative propagation reproduction in plants biology

Leaf tips help in vegetative propagation in

  1. Begonia

  2. Bryophyllum

  3. Sensevieria

  4. Adiantum caudatum
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The tip of the leaf help in vegetative propagation in Adiantum caudatum. It is an evergreen, perennial fern producing fronds up to 60 cm tall from a shortly-creeping rhizome. It is also known as Maidenhair fern because of the shiny black rachis of the leaves. It has buds at the tip of the leaf which helps in vegetative propagation. The buds enter the ground when the leaf bends and touches the soil. There they develop into a new individual. Due to this phenomena, it is also known as walking fern.

So, the correct answer is option D.

Multiple choice natural vegetative propagation reproduction in plants biology

Roots are used in the vegetative propagation of

  1. Ginger.

  2. Chrysanthemum.

  3. Sweet Potato.

  4. Potato.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The asexual reproduction where the vegetative part of the plant which give rise to a new plant is known as vegetative reproduction. Ginger is propagated by the rhizome. Chrysanthemum is propagated by stem cutting. Roots are used in vegetative propagation of sweet potato. The roots bear adventitious buds from which new plants can develop when it is buried in the moist soil. Such roots are called reproductive roots. Potato is propagated by eye of tuber.
So, the correct answer is option C.
Multiple choice natural vegetative propagation reproduction in plants biology

Vegetative propagation by leaves is found in

  1. Albizzia lebbek

  2. Dalbergia sisso

  3. Bryophyllum diagremontianum

  4. Murraya sp
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Bryophyllum diagremontianum is characterized, by the formation of plantlets in leaf notches while attached to the plant. The multiplication of the plant takes place by vegetative propagation. Bryophyllum is multiplied vegetatively by leaves. The leaves of the Bryophyllum has an adventitious bud in its notch which is meristematic in nature and sprouts when attached to the plant. It adventitious bud has the potential to germinate into new plantlet when it falls on the moist soil by rooting.
So, the correct answer is option C.
Multiple choice natural vegetative propagation reproduction in plants biology

Which is wrongly matched?

  1. Agave- bulbils

  2. Penicillium- conidia

  3. Water Hyacinth- runner

  4. Bryophyllum- leaf buds
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Bulbils are a small bulb-like structure which is mainly present in the axil of leaf and stem. Agave bears bulbil which falls on the ground and forms a new plant. It is present in the axil of bracts in agave. Bulbils are considered as modified vegetative and floral buds which stores food and also helps in vegetative propagation of the plants.
Penicillium is propagated by the non-motile spore known as conidia formed on conidiophore.
Water Hyacinth propagates by offsets. An offset is a short thick runner like the branch which produces a new plant at its tip. The offsets grow in all directions from the main stem of the parent plant. 
Bryophyllum is multiplied vegetatively by buds present in the leaves. The leaves of the Bryophyllum has a notch which when falls on the moist soil, germinates into flower. The notch is meristematic in nature which has the potential to germinate into a new plant which has adventitious roots.
So, the correct answer is option C.
Multiple choice natural vegetative propagation reproduction in plants biology

Which of the following plants does not help in vegetative propagation by leaves

  1. Begonia

  2. Kalanchoe

  3. Bryophyllum

  4. Oxalis
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Oxalis propagates through runner and bulbils. Bulbils are a small bulb-like structure which is mainly present in the axil of leaf and stem. The bulbil falls on the ground and form a new plant. In oxalis, the bulbils occur above the base of the fleshy root. Bulbils are considered as modified vegetative and floral buds which stores food and also helps in vegetative propagation of the plants.
Oxalis also propagates by runners where the stem spreads on the ground and develop the root on lower side and leaf on the upper side at the point on the stem and develop into a new plant.
So, the correct answer is option D.
