Question
F growth or development) upwards from the base or point of attachment. (of the movement of dissolved substances) outwards towards the shoot and root apices.
Solution
The text you've provided seems to describe characteristics of plant growth, specifically in relation to how dissolved substances move within the plant. This movement typically involves the transport of nutrients and water from the roots to the shoots (upwards growth) and from the shoots to the roots (downwards growth), often referred to as apical growth.
In plants, growth can be classified into two main types:
-
Primary Growth: This occurs at the apices or tips of roots and shoots, leading to an increase in length. The growth is primarily due to cell division in the meristems, which are regions of undifferentiated cells.
-
Secondary Growth: This type of growth is characteristic of woody plants and occurs later in their life cycle. It increases the thickness of the plant stem or trunk and is facilitated by the vascular cambium.
The movement of dissolved substances, or translocation, is facilitated by vascular tissues (xylem for water and nutrients, and phloem for food). The process is essential for the overall health and growth of the plant, as it ensures that nutrients are available where they are needed most.
In summary, the upwards growth relates to how plants extend towards light, while the movement of dissolved substances allows for effective nutrient distribution throughout the plant structure. This dynamic system is crucial for the plant's development and survival.
