State the location and function of Intercalary meristem.


It is the meristem that occurs between the masses of mature tissues. It occurs in grasses and helps in the regeneration of grasses after they have been grazed by herbivores. Since the intercalary meristem and the apical meristem both appear earlier in a plant’s life and contribute to the formation of the primary plant body, so they constitute the primary meristem.


What are respiratory substrates? Name the most common respiratory substrate.


In the process of respiration, those compounds which get oxidised to release energy are called respiratory substrates. The most common respiratory substrate is glucose.


Which hormone deficiency is responsible for the following?

(a) Diabetes mellitus

(b) Goitre


(a) Diabetes mellitus is characterized by abnormally high glucose levels in the blood due to the deficiency of hormone, called insulin.

(b) Goitre is characterised by an abnormal enlargement of the thyroid gland due to the deficiency of thyroxin hormone in the body.


What is the difference between direct and indirect development?


Direct development: When the life cycle of an adult individual lacks any larval stage in its life cycle, then it is termed as direct development. In this case the adults give rise to young ones which directly develop into the adult, e.g., mammals.

Indirect development: In this type of development, the adult individual gives rise to eggs which develop into the adult after passing through several larval stages, e.g., echinoderms, cockroaches etc.

Explain with suitable examples the different types of phyllotaxy?


Phyllotaxy refers to the pattern or arrangement of leaves on the stem or branch of a plant. There are three types of phyllotaxy which are described as below:

(i) Alternate phyllotaxy: In this type of phyllotaxy, a single leaf arises from each node of a branch in alternate manner. For example: Sunflower, mustard, and China rose.

(ii) Opposite phyllotaxy: Plants with opposite phyllotaxy have a pair of leaves arising from each node and both lie in opposite direction to each other. For example: Guava and jamun plants.

(iii) Whorled phyllotaxy: In this type of phyllotaxy, more than two leaves arise from each node forming a whorl. For example: Alstonia.
