Differbetween
The increase in length of the shoot and the root is referred to as primary growth. It is the result of cell division in the shoot apical meristem. Secondary growth is characterized by an increase in thickness or girth of the plant.

What is the difference between primary and secondary growth quizlet?
Primary growth allows roots to extend downward throughout the soil and shoots to extend upward to increase the plants exposure to light. ... Secondary growth allows for the plant to grow into thickness. Lateral meristems known as the vascular cambium and cork cambium are responsible for secondary growth.
What is the difference between primary and secondary tissue?
They are now called permanent tissues.
...
Differentiate between primary meristem and secondary meristem.
| Primary meristems | Secondary meristems |
|---|---|
| It is present in apical region of plant | It is present in lateral region of plant |
| Example: protoderm, procambium, etc | Example: vascular cambium and cork cambium |
What is secondary plant growth?
Secondary growth is characterized by an increase in thickness or girth of the plant, and is caused by cell division in the lateral meristem. ... Other plant parts, such as leaves and flowers, exhibit determinate growth, which ceases when a plant part reaches a particular size.
What is the relationship between primary and secondary growth in plants?
Meristems contribute to both primary (taller/longer) and secondary (wider) growth. Primary growth is controlled by root apical meristems or shoot apical meristems, while secondary growth is controlled by the two lateral meristems, called the vascular cambium and the cork cambium.
How does secondary growth support primary growth?
In botany, secondary growth is the growth that results from cell division in the cambia or lateral meristems and that causes the stems and roots to thicken, while primary growth is growth that occurs as a result of cell division at the tips of stems and roots, causing them to elongate, and gives rise to primary tissue.
What is the difference between a primary stem and a secondary stem?
Primary Growth: Primary growth is the growth that occurs by the action of the primary meristem, which increases the length of the stem and adds appendages to the stem. Secondary Growth: Secondary growth is the growth that occurs by the action of the cambium, which increases the diameter of the plant.
What are primary and secondary roots?
What are the primary and secondary roots? Primary roots are the early roots in young plants that consist of taproots, basal roots, and lateral roots. Secondary roots are the side branches of the primary roots.
Which is an example of secondary meristem?
Secondary Meristem: Secondary meristems are the meristematic tissue arises from the permanent tissues. Secondary meristems are usually lateral meristems and are responsible for the increase in thickness of the plant. Example: vascular cambium and cork cambium (phellogen).
What is the function of secondary phloem?
The secondary phloem is a type of phloem that forms from the vascular cambium during the secondary growth. The secondary growth is responsible for the growth in girth in plants, especially trees. The vascular cambium is the meristematic tissue involved in this type of growth.
Which is the best example of anomalous secondary growth?
Bougainvillea is a member of the Nyctaginaceae and is an example of a dicotyledonous stem which displays anomalous secondary growth. In this TS, near the centre of the stem, you will see some primary vascular bundles embedded in lignified pith parenchyma.
Which meristem is responsible for secondary growth?
Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots. Lateral meristems are known as secondary meristems because they are responsible for secondary growth, or increase in stem girth and thickness.
What are the 4 stages of plant growth?
Basic Facts
- The average plant goes through four stages: seed, sprout, seedling, adult plant.
- Seed. Through pollination (pollen reaches the stigma) and ferilization (the pollen and stigma join), a seed is formed. ...
- Sprout. The next stage, the sprout, is when the shoot reaches the surface. ...
- Seedling. ...
- Adult Plant.
