Show answer
Correct Option: D
Explanation:

A.Bryophyta – chlorophyllous, aquatic, embryophytic, archegoniatic, plants in the plant kingdom. These are also called amphibian of the plant kingdom.

B.Pteridophyta – Chlorophyllous, terrestrial, embryophytic, tracheophytes in the plant kingdom. These are also called vascular cryptogams.

C.Gymnosperms – Naked seeded plants in the plant kingdom.

D.Angiosperms -  Fruit producing plants in the plant kingdom. These are highly advanced plants. Hibiscus is an angiosperm.

Consider the following statements:

(a) Plants are divided into five groups: Thallophytes, Bryophytes, Pteridophytes, gymnosperms, and Angiosperms.
(b) Monera is divided into Archaebacteria and Eubacteria.
(c) $Penicillium$ and Yeast both belong to group fungi.

Which of the above statements are correct?

botany plant biology introduction to angiosperms phanerogams angiosperms

  1. (a) and (b)

  2. (b) and (c)

  3. (a), (b) and (c)

  4. None of these

Show answer
Correct Option: C
Explanation:

The first level of classification among plants depends on whether the plant body is well-differentiated or not. The next level of classification is based on whether the differentiated body has special vascular tissues for the transport of water and other substances. Further classification is based on the ability to bear seeds and whether the seeds are naked or enclosed within fruits. 
Monera is a kingdom that contains unicellular organisms with no nuclear membrane, such as bacteria. It can be divided into Archaebacteria and Eubacteria.
A fungus is any member of a large group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. Penicillium and Yeast both belong to group fungi.

The orchid plants, which are found growing on the trees, are

  1. Parasites

  2. Epiphytes

  3. Saprophytes

  4. Lithophytes

Show answer
Correct Option: B
Explanation:

Different types of epiphytes may grow on the same tree, including orchids. The name 'epiphyte' comes from the Greek word 'epi' meaning 'upon' and 'phyton' meaning 'plant'

So, the correct answer is 'Epiphytes'

  4. A- 5, B- 3, C- 1, D- 2, E- 4

Show answer
Correct Option: B
Explanation:

Ulothrix is a genus of filamentous green algae, generally found in fresh and marine water. They are eukaryotic and unicellular. The plant body consists of unbranched, uniseriate filaments. The Ulothrix is a thallophyte having undifferentiated bodies. Funaria are nonvascular plants, i.e., they do not have conductive tissues and they perform transport of water and nutrients by diffusion; they are cryptogamic, they are small in size; in their life cycle the lasting form is haploid (the gametophyte) and the sporophyte depends on the gametophyte to survive. Hence it is a bryophyte. The living species of heterosporous pteridophytes are small herbaceous perennials like Marsilea. These pteridophytes possess only one kind of non-sexual reproductive spores and possess the true fibro-vascular system, true roots, and leaves. The genus Pinus can be distinguished by long needles on very short shoots in bundles of 2,3, or 5, strobili on long shoots, and the shoots and foliage are strongly dimorphic. Male and female flowers are separate structures: the female flowers are the structures that will eventually become the familiar cones containing the seeds, and male flowers release pollen, which is then captured by the female cones. Gymnosperm seeds develop either on the surface of scales or leave, often modified to form cones. Thus pinus is a gymnosperm. Ficus is an angiosperm because they are seed-producing plants and have flowers, endosperm within the seeds, and the production of fruits that contain the seeds.

Find out and select the incorrect pair from the following.

botany plant biology introduction to angiosperms phanerogams angiosperms

  1. Phanerogamae- Gymnosperms and angiosperms

  2. Angiosperms- Monocotyledonous and dicotyledonous

  3. Cryptogamae- Bryophyta and Pteridophyta

  4. Pteridophytes- Horsetails and mosses

Show answer
Correct Option: D
Explanation:

Mosses are small flowerless plants that usually grow in dense green clumps or mats, in damp or shady locations. They are bryophytes in the nature.

The horsetails are a class in the Pteridophyta (ferns). They were one of the most important plant groups in the Palaeozoic era.
Therefore, the correct answer is option D.

.............. are the reproductive organs of flowering plants.

botany plant biology introduction to angiosperms phanerogams angiosperms

  1. Seeds

  2. Flowers

  3. Fruits

  4. All of the above

Show answer
Correct Option: B
Explanation:
  • Angiosperms are flowering plants. They reproduce by the formation of gametes and flowers act as reproductive organs. 
  • Parts of the flower include petals, sepals, one or more carpels (the female reproductive structure) and stamens (the male reproductive structure)
  • So, the correct answer is 'Flowers'

Which of the following is an example of dicotyledon seed?

botany plant biology introduction to angiosperms phanerogams angiosperms

  1. Maize

  2. Mustard

  3. Banana

  4. Garlic

Show answer
Correct Option: B
Explanation:
  • The flowering plants (angiosperms) are divided into two groups, namely monocots and dicots. 
  • Monocots- Plants which have only one cotyledon in the seeds are called as monocots. For example, maize, banana, garlic, etc.
  • Dicots- Plants that have two cotyledons in their seeds are called as dicots. For example, mustard, beans, legumes, apples, etc.
