Botany and Plant Science Questions

Multiple choice

The meristem causing primary growth in the plants is

  1. primary meristem

  2. secondary meristem

  3. apical meristem

  4. intercalary meristem

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

It is the meristem, that is present right from the embryonic stage, and continues to be active, throughout the life of a plant. It is responsible for primary growth, in the plant body. It gives rise to the primary permanent tissues, of the plant body.

Multiple choice

The meristem that lies at the nodal regions is

  1. intercalary meristem

  2. apical meristem

  3. secondary meristem

  4. primary meristem

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

It is the meristem, that occurs between permanent tissues. It represents the remnant of the apical meristem. It is particularly common, at the nodal regions. It may also occur, at the base of the leaves. The intercalary meristem also contributes, towards the increase in length, as it brings about elongation, of the internodal regions. It is also responsible, for the formation of branches, at the nodal regions.

Multiple choice

The meristem that lies between permanent tissues is

  1. primary meristem

  2. secondary meristem

  3. apical meristem

  4. intercalary meristem

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

It is the meristem, that occurs between permanent tissues. It represents the remnant of the apical meristem. It is particularly common at the nodal regions. It may also occur at the base of the leaves. The intercalary meristem also contributes, towards the increase in length, as it brings about elongation, of the internodal regions. It is also responsible, for the formation of branches, at the nodal regions.

Multiple choice

Epidermis originates from

  1. Protoderm

  2. Lateral Meristem

  3. Ground Meristem

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

It is the meristem, that always differentiates, into protective structures, like epidermis.

Multiple choice

Which of the following is the vestige of the apical meristem?

  1. Secondary Meristem

  2. Intercalary Meristem

  3. Primary Meristem

  4. Apical Meristem

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

It is the meristem, that occurs between permanent tissues. It represents the remnant of the apical meristem. It is particularly common, at the nodal regions. It may also occur, at the base of the leaves. The intercalary meristem also contributes, towards the increase in length, as it brings about elongation, of the internodal regions. It is also responsible, for the formation of branches, at the nodal regions.

Multiple choice

The cambium strips can be regarded as an example of

  1. secondary meristem

  2. apical meristem

  3. intercalary meristem

  4. lateral meristem

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

It is the meristem, that occurs laterally, parallel to the long axis of plant body. Cambium strips formed in the vascular bundles, and in the cortex are common examples, of lateral meristem. It is responsible for an increase in the girth (circumference) of the plant body, as it brings about the formation, of secondary permanent tissues.

________ meristem causes elongation of the internodal regions

  1. primary meristem

  2. secondary meristem

  3. apical meristem

  4. intercalary meristem

It is also responsible, for the formation of branches, at the nodal regions.

Multiple choice

Xylem and phloem originates from

  1. lateral meristem

  2. protoderm

  3. procambium

  4. ground meristem

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

It is the meristem, that always differentiates, into the vascular tissues like, xylem and phloem.

Multiple choice

Which of the following is an example of secondary meristem?

  1. Primary Meristem

  2. Lateral Meristem

  3. Apical Meristem

  4. Intercalary Meristem

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

It is the meristem, that occurs laterally, parallel to the long axis, of plant body. Cambium strips formed in the vascular bundles, and in the cortex, are common examples, of lateral meristem. It is responsible, for an increase in the girth (circumference) of the plant body, as it brings about the formatio,n of secondary permanent tissues. The lateral meristem, is an example of, secondary meristem. C. Based on Differentiation

Multiple choice

Cork cambium and vascular cambium are examples of

  1. primary meristem

  2. apical meristem

  3. secondary meristem

  4. intercalary meristem

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

It is the meristem, that appears later, in the life cycle of a plant. It develops by a process, called dedifferentiation in the permanent tissues. It is responsible, for secondary growth in the plant body. It gives rise to secondary permanent tissues, such as, secondary cortex and secondary xylem. Example: Cork cambium and vascular cambium.
