The answer for the question is the Apical meristem.
Growth in plants occurs as the stems and roots lengthen. Some plants, especially those that are woody, also increase in thickness during their life span. 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.
The study of plants is called botany. There are different types of plants in the living being and these are algae, bryophytes, pteridophytes, gymnosperm, and angiosperm.
The correct answer is mentioned as follows:-
<h3>GYMNOSPERM</h3>
- The less developed plant which does not bear flowers and has covered less seed is called gymnosperm.
According to the question, the diagram is not mentioned in the question hence we can not able to tell the characteristics of the area marked as X. The plants do not look like palm trees.
Hence, provide it with the diagram for better assessment.

The given example suggests the principle of resource partitioning.
The resource partitioning is a method of division of resources present in a particular niche to avoid the competition. In this case, the organism divide the regions having the abundant resources and they do not interfere in each others region.
In this case, the resource partition takes place by dividing the regions in the flask. one species use he resources present in the middle region and other uses the resource in the bottom.
<u>Answer:</u>
<em>An LH spike occurs during oestrogen feedback loop because the pituitary gland positively responds to the high level of oestrogen </em>and produces more LH.
During the ovulatory phase the amount of hormones like oestrogen, follicle stimulating hormone and Leutenising hormone are high. <em>FSH enables the formation of follicles and LH enables the rupture of matured follicle and release of ovum into the oviduct. </em>
In the middle of menstrual cycle when the amount of oestrogen is high pituitary gland give <em>a positive feedback by producing more LH.</em>
<em>This is called LH surge.</em> By this time primary follicles would have matured into graffian follicle and would be holding the ovum. <em>LH surge causes the follicle to rupture and the ovum gets released into the oviduct. </em>
