What else can I help you with?
If there are drought conditions why might a plant produce seeds rather then grow new plantlets?
Because new plants (plantlets) would require water immediately to survive, where as seed can lie dormant until it rains (the drought is broken) and the seed can germinate and form new plants. It's a matter of conserving resources.
How long will seeds last without rain?
The length of time seeds can survive without rain depends on various factors such as the type of seed, environmental conditions, and seed storage conditions. Generally, seeds can remain viable for several months to years without rain if they are stored properly in a cool and dry environment. Some seeds have evolved mechanisms to withstand periods of drought by entering a dormant state until water becomes available.
What is the strategy that allows seeds to survive long periods of bitter cold or extreme heat or drought?
Impervious seed coat and little moisture content in its embryonic and storage tissues coupled with various types of seed dormancy help seeds to survive long period of bitter cold, extrem heat or drought conditions.
Why does a plants produce so many seeds?
Because not all of them find conditions that are suitable for germination. After germination a number will die or be eaten by pests, killed or damaged mechanically, die because of drought, frost etc. The more seeds the greater chance for the survival of a few plants.
What are drought tolerant seeds?
Drought-tolerant seeds are specially bred or genetically modified seeds designed to thrive in conditions with limited water availability. These seeds exhibit traits such as deeper root systems, reduced water loss, and enhanced resilience to heat and drought stress. Commonly used in agriculture and landscaping, they help conserve water resources and maintain crop productivity in arid or drought-prone regions. Using drought-tolerant seeds can also contribute to sustainable farming practices and environmental conservation.
What physiological adaptation helps annual plants whose climate has long periods of drought followed by brief periods of rain?
The physiological adaptation of annual plants to long periods of drought followed by brief periods of rain is the ability to rapidly germinate and complete their life cycle within a short timeframe. This allows them to take advantage of the brief periods of rain to grow, reproduce, and set seeds before the next drought period. Additionally, some annual plants have developed mechanisms to store water or reduce water loss through factors like waxy leaves or shallow root systems.
The beaks of finches on the Galapagos Islands enlarged over generations in response to what factor?
The beaks of finches on the Galapagos Islands enlarged over generations in response to variations in food sources. Larger beaks were favored for cracking tougher seeds during periods of drought when softer seeds were scarce. This adaptation allowed finches with larger beaks to better survive and reproduce, passing on their genes for larger beaks to the next generation.
Could you survive without seeds?
no no seeds no food
How seeds with a hard outer covering enabled angiosperms to survive in a wide variety of climates?
because their seeds are enclosed and protected
Why are so many seeds produced?
By a plant? To ensure maximum survival. The more you produce, the more likely it is that some survive. It's evolution at its simplest. Plants usually produce far more seeds than are needed. This is because many seeds don't survive and grow to maturity
Infer how seeds with a hard outer covering enabled angiosperms to survive in a wide variety of climates?
Seeds with a hard outer covering, also known as seed coats, provide protection and insulation for the embryo within. This protection allows seeds to survive harsh environmental conditions such as extreme temperatures, drought, and predators. The hard seed coat also helps regulate the germination process, ensuring that seeds only sprout when conditions are favorable for growth, thus increasing the chances of survival in a wide range of climates.
Why do plant store food?
Because then if theres a drought, they have water... I'm pretty sure. Or not nesasarly a drought. but whatever. One very good reasons is to aid the growth and survival of their seeds. Plants have evolved to nurture their children just as humans have, though in a very different way. You will have noticed that within almost every fruit and some vegetables lies one or more seeds. The point of this beautiful sweet food is not for us to eat, but as an energy source for the seed as it grows into a young seedling and starts photosynthesising for itself! It is also essential to survive at night or during dark weather or drought, when sunlight or water is not available for photosynthesis. Plants will then draw on these energy stores until energy production can begin again.
