What are the advantages and disadvantages of a seed growing near the parent plant?
Since plants are non-motile, if a seed grows beneath a parent plant, it may be deprived of water, soil nutrients and solar energy due to the root system of the parent plant as well as its greater height..
What protects a seed while it is being dispersed?
Fruit is the part of the plant that protects seeds as they grow. Fruits can be fleshy and juicy—like apples and oranges—or dry like nuts or peas. … Plants rely on animals and wind and water to help scatter their seeds.
What are 3 ways animals disperse seeds?
Animals can disperse seeds by excreting or burying them; other fruits have structures, such as hooks, that attach themselves to animals’ fur. Humans also play a role as dispersers by moving fruit to new places and discarding the inedible portions containing the seeds.
Does every plant come from a seed?
Not every plant grows from a seed. Some plants, like ferns and mosses, grow from spores. Other plants use asexual vegetative reproduction and grow new plants from rhizomes or tubers. We can also use techniques like grafting or take cuttings to make new plants.
What will happen if all the fruits and seeds of a plant fall under it?
If all the seeds of a plant fall under the parent plant, there will be shortage of space for the germination of the seeds. Even if they germinate, they cannot grow properly due to scarcity of food resources and also space. Thus some of them will fail to grow. … For all these reasons, seed dispersal is necessary.
Why do plants scatter their seeds Class 5?
Answer: Plants scatter their seeds in order to insure that they don’t grow to close to each other.
Do all seeds germinate immediately after they are dispersed?
All seeds germinate immediately after they are dispersed. (h. The embryo uses its stored food to begin to grow.
What would happen if the plants do not get water?
When plants are not watered properly they wilt. … When a plant is properly hydrated, there is enough water pressure to make the leaves strong and sturdy; when a plant doesn’t get enough water, the pressure inside the stems and leaves drops and they wilt. Plants also need water for photosynthesis.
What will happen if there is no seed dispersal?
If the seeds did not spread out, they would fall in the parent bed itself leading into struggle for water, minerals and sunlight. As a result, none of the plants would grow properly or survive.
Can a plant grow without its seed?
Plants can grow without producing seeds. … The second way is called asexual or vegetative reproduction where plants develop offshoots, suckers from the roots, or simply allow one of its branches to trail along the ground and develop roots wherever it touches the ground.
How does a seed scatter away from its mother plant?
Most plants have strategies to disperse their seeds which ensure that they germinate away from the parent plant. These include gravity, wind, water, explosive forces, and dispersion by animals including humans. …
What would happen if seeds did not spread and remained at one place only?
Answer. if seeds did not spread and remained at one place, then they may not get enough nutrients for growing as all of them need nutrients. and when they grow, it will cause overcrowding in one place and all cannot grow at a place. all need nutrients but they cannot take all from a single place.
Why is it important for a seed to fall away from the parent plant?
Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
What are the conditions necessary for seed germination?
Seed germination depends on both internal and external conditions. The most important external factors include right temperature, water, oxygen or air and sometimes light or darkness.
What was the first plant on earth?
The first land plants appeared around 470 million years ago, during the Ordovician period, when life was diversifying rapidly. They were non-vascular plants, like mosses and liverworts, that didn’t have deep roots. About 35 million years later, ice sheets briefly covered much of the planet and a mass extinction ensued.
What do you know about seed germination?
Seed germination may be defined as the fundamental process by which different plant species grow from a single seed into a plant. This process influences both crop yield and quality. A common example of seed germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm.
What would happen if all the seeds try to germinate in a single place?
If all seeds of a plant fall on same place: In favorable environmental conditions, they germinate there and become overcrowded. They compete for sunlight and water and fight for their survival and many plants would die. … Because, in nature same kind of plants grow at different places.
What was the first seed on earth?
Scientists believe that an extinct seed fern, called Elksinia polymorpha, was the first plant to use seeds. This plant had cup-like features, called “cupules”, that would protect the developing seed. These cupules grew along the plant’s branches.
