, Question 1
1.1 Briefly explain the following terms
1.1.1 Essential element
An essential element is a chemical element that a plant needs in order to grow and
complete its life cycle. Without this element, the plant cannot grow properly or
reproduce. These elements are needed for important processes such as
photosynthesis, enzyme activity and building plant tissues.
1.1.2 Carbon partitioning
Carbon partitioning refers to the way plants distribute carbon compounds, mainly
sugars produced during photosynthesis, to different parts of the plant. These sugars
can be used for growth, storage or energy in different plant organs like roots, stems and
fruits.
1.1.3 Sink activity
Sink activity is the ability of certain plant tissues or organs to receive and use sugars and
nutrients transported from the leaves. These tissues are called sinks and include
growing roots, fruits, seeds and young leaves where nutrients are needed for growth and
development.
1.1.4 Critical concentration
Critical concentration is the minimum amount of a nutrient that must be present in
plant tissue for normal plant growth. If the nutrient level drops below this point, the
plant may start showing deficiency symptoms and growth can be reduced.
1.1.5 Mucigel
Mucigel is a sticky gel-like substance found around plant roots. It is produced by root
cap cells and microorganisms in the soil. This substance helps the root move easily
through the soil and also helps in retaining water and nutrients around the root surface.
1.2 Define mycorrhizae, citing the two main classes and their differences
Mycorrhizae are symbiotic relationships between plant roots and fungi in the soil. In this
relationship, the fungus helps the plant absorb water and nutrients, especially
phosphorus, while the plant provides the fungus with carbohydrates produced during
photosynthesis.
There are two main types of mycorrhizae:
