Plant development is influenced bya)quality of light onlyb)quality and...
Plants and animals are separated by about 1.5 billion years of evolutionary history. They have evolved their multicellular organization independently but using the same initial toolkit — the set of genes inherited from their common unicellular eucaryotic ancestor.
Two basic peculiarities of plants are:
First, they get their energy from sunlight, not by ingesting other organisms. This dictates a body plan different from that of animals.
Second, their cells are encased in semirigid cell walls and cemented together, preventing them from moving as animal cells do.
This dictates a different set of mechanisms for shaping the body and different developmental processes to cope with a changeable environment.
Because they cannot match themselves to their environment by moving from place to place, plants adapt instead by altering the course of their development. Their strategy is opportunistic. A given type of organ—a leaf, a flower, or a root, say—can be produced from the fertilized egg by many different paths according to environmental cues.
Hence, Plant development is influenced by quality, quantity and duration of light.

Plant development is influenced by:
Quality of light:
- Different wavelengths of light have different effects on plant growth and development.
- Plants use specific wavelengths of light, such as red and blue light, for photosynthesis.
- Quality of light also affects the timing of flowering and fruiting in plants.
Quantity of light:
- The intensity or brightness of light affects the rate of photosynthesis in plants.
- Plants require a certain amount of light to produce enough energy for growth and development.
- Insufficient light can lead to weak and spindly growth, while excessive light can cause damage to plant tissues.
Duration of light:
- The length of time that plants are exposed to light, also known as photoperiod, influences various developmental processes.
- For example, some plants require specific day lengths to initiate flowering.
- The duration of light also affects the production of certain hormones that regulate plant growth.
Overall:
- Plant development is influenced by the quality, quantity, and duration of light.
- The specific combination of these factors determines how plants grow, flower, and produce fruits.
- Understanding and manipulating these factors can be used in horticulture and agriculture to optimize plant growth and productivity.
