Question 1
1 / -0

Plant having column of vascular tissues bearing fruits and having a tap root system is?

A
Monocot

B
Dicot

C
Gymnosperm or dicot

D
Gymnosperm or monocot

Solution

Dicot
$$\to$$ Characteristics of dicot root and stem
Stem
$$\bullet$$ Vascular cambium is the form of a circular strip or ring from the beginning.
$$\bullet$$ Vascular cambium is made up of both primary and secondary strips of meristematic tissues.
$$\bullet$$ Annual rings are quite common.

Root
$$\bullet$$ Root arises from the radicle of the embryo. It may also arise from any other port of the plant.
$$\bullet$$ Roots are nongreen.
$$\bullet$$ The Root is positively geotropic hydrotropic neutral or negatively phototrophic.
$$\bullet$$ A root cap is formed at the tip of the root.
Question 2
1 / -0

Meristematic tissue occurs in ________.

A
Stems

B
Roots

C
All growing tips

D
Both A and B
Solution
Meristematic tissue is the undifferentiated tissues which have the ability to divide continuously.
They are present at the shoot tip and root tip in plants.
They are composed of actively dividing metabolic cells.
Apical meristematic tissues are present at the growing tips and help in the elongation of plants.
Intercalary meristematic tissues are present at the nodes and internodes in stems and leaves which are residual apical meristems which help in increasing the length of the plant.
Both apical and intercalary meristematic tissues help in primary growth of the plant.
Lateral meristematic tissue or secondary tissue are found in woody plants (consist of the vascular cambium and the cork cambium) which helps to increase the thickness in plants.
They form cambial rings in stems and roots.
So, the correct answer is 'All growing tips'
Question 3
1 / -0

Primary plant growth is accomplished by _______.

A
Cambia

B
Intercalary meristem

C
Apical meristem

D
Mass meristem
Solution
The apical meristems are present at the shoot tips and root tips in plants.
They are actively dividing cells which helps in the elongation of shoot tip and root tip.
The intercalary meristems are present at the base of nodes and internodes of stems and leaf.
They help in increasing the length of the plant, the formation of petiole etc.
These meristematic tissues are responsible for the primary growths in plants which are achieved by increasing the length of the plants and by elongation of shoot tip and root tip.
So, the correct answer is 'Apical meristem'.
Question 4
1 / -0

Monocot characteristics are

A
Fibrous root system, parallel-veined leaves, trimerous flowers and two cotyledons

B
Fibrous root system, parallel-veined leaves, trimerous flowers and one cotyledon

C
Fibrous root system, reticulate veined leaves, trimerous flowers and one cotyledon

D
Tap root system, parallel venation, trimerous flowers and one cotyledon

Solution

Monocot plants, as the name suggests have only one cotyledon. these plants have characteristic features like fibrous root system because the radicle is short-lived, thus replaced by adventitious roots. They also have parallel-veined leaves and trimerous flowers.
So the correct answer is 'Fibrous root system, parallel-veined leaves, trimerous flowers, and one cotyledon'.
Question 5
1 / -0

Apical meristem divides to form three meristematic regions.

A
Dermal, vascular and ground

B
Calyptrogen, periblem and plerome

C
Protoderm, procambium and ground meristem

D
Lateral, intercalary and subapical

Solution

The shoot apical meristem i.e. SAM of the plant form the three distinct meristematic zones which are the histogens.

Each of these histogens will rise to tissues which are different from one another. The root apical meristem gives rise to three primary meristems i.e. procambium, ground meristem, protoderm, and the root cap. Calyptrogen is the internal meristematic cell derived from the root apical meristem.

So, the correct answer is C.
Question 6
1 / -0

Cortex is formed from

A
Cambium

B
Procambium

C
Ground meristem

D
Protoderm
Solution
In plants, the cortex forms the outermost layer of the stem or root which are surrounded by the epidermis layer.
Cortex is made up of differentiated cells which are large and thin-walled parenchyma cells.
The outer cortical cells of the cortex have irregularly thickened collenchyma cells.
The parenchyma and collenchyma cells are a part of the ground tissue system.
So, the correct answer is 'Ground meristem'
Question 7
1 / -0

Outermost part of bark consisting of dead cells refers to

A
Rhytidome

B
Phellem

C
Phellogen

D
Phelloderm

Solution

phellem is the tissue made up of the dead cells filled with tannins. It is the outermost layer of bark which is produced by phellogen or cork cambium to protect vital tissues from drought and desiccation.
Question 8
1 / -0

Axillary and terminal buds develop by activity of _______.

A
Lateral meristem

B
Intercalary meristem

C
Apical meristem

D
Parenchyma
Solution
- The axillary bud is also known as a lateral bud.
- It is situated at the region where the leaf petiole gets attached to the stem
- These buds are capable to form shoots, it can form vegetative shoots (stems and branches) or reproductive shoots (flowers).
- The terminal bud is also known as apical bud which is the primary growing point situated at the tip of the stem which forms the dominant bud.
- The terminal bud can make the lateral buds dormant (apical dominance).
- Both the buds are formed by the activity of shoot apical meristem.
- So, the correct answer is 'Apical meristem'.
Question 9
1 / -0

The formation of annual rings in dicot stem mainly depends upon difference in.

A
Formation of unequal quantities of xylem and phloem

B
Activity of vascular cambium due to seasonal variations

C
Activity of cork cambium due to seasonal variations

D
Formation of unequal quantities of sapwood and heart wood

Solution

In dicotyledonous stems, during intra stelar secondary growth, intra fascicular cambium(primary meristem) and inter fascicular cambium(secondary meristem) joins together and form into a ring of cambium is called vascular cambium. It is partly primary meristem and partly secondary meristem. Its activity is continuous and uninterrupted. Due to the seasonal influence, it produces two types of secondary xylems, spring wood and autumn wood. Both these woods, together form into a ring of wood called annual ring or growth ring. Every

annual ring becomes sap wood and every sap wood gradually transform into heart wood. Due to these transformations amount of heart wood increases.

so, the correct option is 'Activity of vascular cambium due to seasonal variations'.
Question 10
1 / -0

A
Oat

B
Sugarcane

C
Apple

D
Castor
