Studies have showed that advanced rainfall during the growing period can lead to
an improvement in the utilization of soil water
, which is beneficial to root growth

. By contrast, delayed rainfall often increases the availability of soil water at the later stage of growth, thus delaying the plant senescence

Why is rainfall important to plants?
Plants use the moisture in the soil to replenish the water lost through transpiration. If there is no water in the soil, the leaves will wilt. As more water is lost, the plant will fail and eventually die.
Rainwater builds up the moisture levels in the soil
and assures a healthy plant.

How does water impact the growth of plants?
Water helps a
plant by transporting important nutrients through the plant
. Nutrients are drawn from the soil and used by the plant. Without enough water in the cells, the plant will droop, so water helps a plant to stand upright. … Too much water will affect plant growth just as much as too little.
How does rainfall affect flora?
When this compound falls in the form of rainwater,
the soil absorbs it
. The acidic nature of this rainwater dissolves and removes the nutrients in the soil and increases minerals that are harmful to plants. Frequent exposure to acid rain kills plants.
How do plants and animals respond to changing seasons?
Sometimes animal adaptations are triggered by weather and seasonal changes. … Some plants become dormant and some animals undergo changes to prepare for the winter. Some animals collect food to store during the winter months and others hibernate, migrate, or grow thicker fur.
What are the factors affecting plant growth?
Environmental factors that affect plant growth include
light, temperature, water, humidity, and nutrition
. It is important to understand how these factors affect plant growth and development.
How does temperature affect plant growth?
Germination
increases in higher temperatures – up to a point. Once the seeds reach optimum temperatures, which depends on the plant, germination begins to decline. … So whether it's extreme heat or cold, temperature does affect plants and their growth.
What type of water is best for plant growth?
- To give your plants the absolute best, rainwater and bottled spring water are your best options. …
- While distilled water won't actually harm your plants, you will notice that your plants won't grow as quickly or as tall as plants watered with rainwater or bottled spring water.
What do you call a period without rain?
A drought
is a long period of time during which no rain falls.
What happens when there is too much rainfall?
Heavy rainfall can lead to numerous hazards, for example:
flooding
, including risk to human life, damage to buildings and infrastructure, and loss of crops and livestock. landslides, which can threaten human life, disrupt transport and communications, and cause damage to buildings and infrastructure.
What does too little rain lead to?
When little or no rain falls,
soils can dry out and plants can die
. When rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases.
How do plants respond to different seasons?
Plants can respond to the change of season by
losing their leaves, flowering, or breaking dormancy
. Plants go through seasonal changes after detecting differences in day length.
How do plants change with the seasons?
Plants can sense changes in the seasons.
Leaves change color and drop each autumn
in some climates (Figure below). Leaves changing color is a response to the shortened length of the day in autumn. … And, in the spring, the winter buds on the trees break open, and the leaves start to grow.
How did the seasonal plants and animals respond to the rains?
The response of an organism, usually a plant, to an environmental stimulus is called a
tropism
. … The naming of the tropism is associated with the stimulus. For example, the movement of plant roots towards water is called hydrotropism.
What are the 5 factors affecting plant growth?
Light, water, temperature, humidity, ventilation, fertilization, and soil
are chief factors affecting plant growth, and any one of these factors in incorrect proportions will prevent proper plant growth indoors. Light is probably the most essential factor for house plant growth.
