Question 1
1 / -0

Meristems are

A
Permanent cells

B
Dividing cells

C
Mechanical cells

D
None of the above

Solution

A meristem is the tissue in most plants containing undifferentiated cells, found in zones of the plant, where growth can take place. Meristematic cells give rise to various organs of the plant and keep the plant growing. The shoot apical meristem gives rise to organs like the leaves and flowers, while the root apical meristem provides the meristematic cells for the future root growth.
So, meristems are dividing cells and not permanent cells as, they differentiate to give various organs
So, the correct answer is 'Dividing cells'
Question 2
1 / -0

Exarch and polyarch xylem strands are found in

A
Monocot stem

B
Dicot stem

C
Monocot root

D
Dicot root

Solution

In monocot root vascular bundles are radial in arrangement. There are eight bundles each of xylem and phloem. Hence, the condition is described as polyarch. Xylem is described as exarch in monocot root.
Question 3
1 / -0

In maize, ............. roots are present other than the normal roots.

A
Stilt roots

B
Tuberous roots

C
Prop roots

D
Nodulated roots
Question 4
1 / -0

Periblem gives rise to

A
Epidermis

B
Cortex

C
Cortex and endodermis

D
Endodermis

Solution

In the histogen theory Henstein divided the shoot apex into various zones. Each zone consists of a group of initial cells and called as histogen or a tissue builder.
The major histogens of the stem and roots are -(a) the dermatogen, a meristematic external layer, (b) the plerome, a central core and (c) the periblem, the region between the two.
The dermatogen gives rise to the epidermis, the prerome to the primary vascular bundles and the periblem develops into the cortex and endodermis.
Question 5
1 / -0

Which of the following does not contain pith?

A
Siphonostele

B
Protostele

C
Eustele

D
None of the above

Solution

Protostele is the most primitive type of stele with central xylem surrounded by phloem and pericycle. Pith is absent in them. Medullation (appearance of pith) of a protostele with central pith is called as siphonostele and thus has central pith surrounded by xylem, phloem and pericycle. Separation of vascular strands by parenchyma in siphonostele give rise to eustele. Thus, the correct answer is option B.
Question 6
1 / -0

Which is not true for dicot root _____________.

A
Less developed pith or absent

B
Secondary growth

C
Both

D
$$15-20$$ vascular bundles

Solution

In dicot root vascular bundles are 2 to 6 in number and radial.
Hence, the answer that is not true for dicot is presence of 15-20 vascular bundles.
So, the correct answer is '15-20 vascular bundles'
Question 7
1 / -0

Plant length is increased by the activity of ________________.

A
Apical meristem

B
Lateral meristem

C
Cambium

D
All of the above

Solution

Lateral meristems are vascular cambium and cork combium. They are responsible for secondary growth of plant. They increase plant diameter. Cambium are of two types as vascular cambium and cork cambium. Cambium possess meristematic cells which are involved in secondary growth. They increase plant diameter.
Apical meristem are present at the tip of root and shoot. Cells of apical meristem divide and give rise to new cells. This process increase the length of root and shoot.
Question 8
1 / -0

The terminal and axillary buds arise from

A
Apical meristem

B
Intercalary meristem

C
Lateral meristem

D
Parenchyma

Solution

The terminal bud arises from the tip of the stem and axillary buds arise from the leaf node of the stem. Hence both the terminal and axillary buds arise from the apex (apical meristem).
So, the correct answer is 'Apical meristem'.
Question 9
1 / -0

Select the statement which correctly describes tissues.

A
Group of cells with common origin but dissimilar functions.

B
Group of cells with common origin and similar structure.

C
Group of cells which perform similar function.

D
Group of cells with common origin, similar structure and similar function.
Question 10
1 / -0

Vascular bundles with cambium are called ___________.

A
Closed

B
Open

C
Exarch

D
Endarch

Solution

If vascular bundles are containing the cambium in between xylem and phloem. It is called open vascular bundles, and it presents in dicots. If vascular bundles do not have cambium in between the xylem and phloem, then it is called as closed vascular bundles. In endarch, the protoxylem is directed towards the centre, whereas in exarch the protoxylem is directed towards the periphery.

So, the correct answer is 'Open' i.e. B.
