Explanation / Answer

Explain how continued growth in plants allows them to cope with environmental challenges?

changes in Patterns of differentiation and the rapid genetic changes show that plant species started with a pool of genetic variation. genetic diversity offered the plant populations flexibility to a rapidly changing world environment. plants have acquired the capability to biosynthesize an unusual array of structurally complicated bioactive natural compounds with specialized roles in order to cope with environmental challenges.The exceptional chemical complexity is located in toxic resistance compounds which plants use to stop herbivores and pests.

some example of plants due to environmental stress:  

Root adaptations to soils with low fertility and aluminium toxicity

Organisms in a desert ecosystem adapt to survive the intense heat and limited water. Plants adapt to be able to find and store water, as well as prevent water loss via evaporation.

How does an apical meristem maintain a constant size?

It maintains constant size through active cell division.

Describe the structure and function of an apical meristem

Apical meristem is a region of rapidly-dividing cells found at a plant's root and shoot tips. Division of these cells always results in primary (vertical) growth, both at the root and shoot. This type of tissue is undifferentiated. However, plants can survive some loss or damage to apical meristem.

What are three functions of the shoot apical meristem?

It produces lateral organs, stem tissues and regenerates itself.
