Question

A plant's life cycle is
A. Time and condition needed to take a plant from germination to reproduction and finally death.
B. Time taken by the plant to flower.
C. Time from birth to germination of a plant.
D. None of the above

Answer 1

Hint:The life cycle of a plant is considered to begin from the point of seed germination, after which it matures to a fully grown plant, and from there on attains reproductive maturity and produces seeds and fruits, and ultimately dies, allowing the produced seeds to germinate and begin a new cycle.

Complete answer:Plants are distinct organisms and have their own life cycles. Even though there is an innumerable number of plant species, each differing in size, shape, metabolic function, and much more, follow a very common life cycle.
Plants capable of propagation via seeds being their life cycle from the germination of the seed. The seed with appropriate environmental conditions germinates to produce a small plant. Once the plant has germinated the roots and shoots start growing.
After a given time the plant matures into a functionally stable organism and attains reproductive maturity, where it undergoes the process of fertilization and produces seeds
These seeds become fruits or spores and disperse throughout the geographic location via air, water, animals, insects, etc. The dispersed seeds under the right conditions being their own life cycle from germination. And the previous plant dies after fluorescence and fruit production.

Thus, the correct option is A, Time, and condition needed to take a plant from germination to reproduction and finally death.

Note:Life cycle of plants is a generalized concept, not all plants follow a defined life cycle.
Plants are of different types and species and each species have their specific form of the life cycle.
There are plants that do not propagate via, seeds and follow a different form of plant growth and reproduction.
Not all plants produce flowers or fruits which can be dispersed.
Trees live up to 1000 years whereas the common tomato plant dies after bearing fruit, thus there is no set time for the life cycle, and depends on the species.
Even though there are many factors to be considered, the time taken by a plant to grow into a mature plant, reproduce and die is generally termed as the life cycle of the plant.
