What is a plant that has a life span of two years?
A biennial plant is a flowering plant that takes two years, generally in a temperate climate, to complete its biological life cycle. In the first year, the plant undergoes primary growth, in which its leaves, stems, and roots (vegetative structures) develop.

Which plant has life span of 1 year?
Annuals, Biennial, and Perennials Plant species that complete their life cycle in one season are known as annuals, an example of which is Arabidopsis, or mouse-ear cress. Biennials, such as carrots, complete their life cycle in two seasons.
Which plant has lifespan?
The longest-lived organisms are plants. For example, one bristlecone pine tree in eastern California is forty-nine hundred years old, and some creosote bushes, also in California, are estimated to be about twelve thousand years old.
Do plants ever die of old age?
All plants die eventually. Unlike animals, plants do not have a set age or size where they are considered “mature” or even “old.” Plants have “indeterminate growth.” If conditions are right, they just keeping growing with almost no limitations.
Does caffeine affect plant growth?
Caffeine, a chemical stimulant, increases the biological processes in not only humans but plants as well. Studies involving the use of caffeine on plants have shown that, initially, cell growth rates are stable but soon the caffeine begins to kill or distort these cells, resulting in a dead or stunted plant.
