The lens or strophiole is usually present in the seed(coats) of members of.

  1. Fabaceae

  2. Asteraceae

  3. Malvaceae

  4. Solanaeae
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The lens (strophiole) is a specialized structure found in Fabaceae (legume) seeds, appearing as a lens-shaped thickening near the hilum. It plays a crucial role in water absorption during germination. This characteristic is specific to legumes and is not found in Asteraceae, Malvaceae, or Solanaceae seeds. Note that 'Solanaeae' is a typo for 'Solanaceae'.

So, the correct option is 'Fabaceae'
Multiple choice botany families of angiosperms family fabaceae eudicots family - fabaceae, sativum and solanaceae study of some important families

Which of the following are not characteristic features of the family Fabaceae?

  1. Tap root system, compound leaves and raceme inflorescence

  2. Flowers actinomorphic, twisted aestivation and gamopetalous

  3. Stamens ten, introse, basifixed and dithecous

  4. Monocarpellary, ovary, superior and bent stigma

  5. Fruit is legume
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Characteristic features of the family Fabaceae are -
1. Leaves are usually alternate and compound.
2. The flowers are zygomorphic and in general, have five fused sepals.
3. The petals are also five free.
4. The presence of having a short usually cup-shaped hypanthium.
5. Stamens ten in number, superior ovary and curved style.
6. Placentation marginal.
Flowers of Fabaceae do not show actinomorphic nature, twisted aestivation and gamopetaly. Thus, the correct answer is option B.

Multiple choice botany families of angiosperms family fabaceae eudicots family - fabaceae, sativum and solanaceae study of some important families

Which of the following is not a characteristic feature of Fabaceae?

  1. Descendingly imbricate, ten stamens, diadelphous, ovary superior

  2. Sepals five, gamosepalous, imbricate aestivation, placentation axile

  3. Monocarpellary, ovary superior, style long, slightly bent at the apex

  4. Zygomorphic flowers, diadelphous stamens, many ovules

  5. Corolla five petals, polypetalous, anterior one large and outermost
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Fabaceae is known as Leguminosae or bean and pea family. This single monophyletic family has three sub-families such as Mimosoideae, Caesalpinioideae and Papilionoideae.
While the family is characterized by presence of five sepals, zygomorphic flower, gamesepelous and has an imbricate aestivation, the placentation is marginal with one elongated placenta on one side of the ovary (superior) and ovules attached at the fusion of the carpel's margins and not axile ( where the ovary is sectioned by radial spokes with placentas in separate locules).
Therefore, the correct answer is option B.

Match the columns and choose the correct option from the following.

A Macrosclereids  1  Hair like cells in roots of Monstera
 B  Osteosclereids  2  Bone like cells xerophytes
 C  Astrosclereids  3  Star shaped cells in hygrophytes
 D  Trichosclereids  4  Stone like cells in seed coat of Fabaceae

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

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

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

  4. A- 2, B- 4, C- 3, D- 1
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Macrosclereids are elongated sclerieds usually found in outer layer of seed coat of legume seeds. These cells are responsible for restricting water uptake by hard seeded legumes. These are found in Fabaceae. 

Osterosclereids are columnar cells similar to macrosclereids, except they are enlarged at the ends making them bone shaped. They are present in xerophytes. 
Astrosclereids are branched, pointed, irregular (often star shaped) sclereids. They can be found in specialized tissues, like the floating leaves of water lily, hygrophytes. 
Trichosclereids are uncommon cells. They can be found in the leaves of olive and the areal roots of Swiss cheese plant (Monstera). 
Thus, the correct answer is option A.

A Correct answer
Explanation

The Fabaceae or Leguminosae, commonly known as the legume, pea or bean family, are a large and economically important family of flowering plants. It includes trees, shrubs and herbaceous plants perennials or annuals, which are easily recognized by their fruit and their compound, stipulated leaves. The group is widely distributed and is the third-largest land plant family in terms of number of species, behind only the Orchidaceae and Asteraceae, with 630 genera and over 18,860 species. So, Fabaceae is an alternative of Leguminosae and not Solanaceae, Compositae and Malvaceae. 
Therefore, the correct answer is option A.
