The seed leaves have carried out the function they are there for and are of no further use.

What is the function of the seed leaves?
The seed leaves provide the seedling with food to grow before the appearance of leaves that enable the plant to make its own food.
Why cotyledon becomes smaller when a bean seed germinates?
The plant uses up the nutrients stored in the cotyledons, they become smaller and eventually drop off once the plant is able to produce food for its self
What is an angiosperm that has two seed leaves?
A dicotyledon. Indicative of dicots.
What is the order of germination?
After a seed is dispersed, it may remain inactive for a while before it germinates. Germination starts when the seed absorbs water from the environment . The embryo then uses its stored food to grow, first the embryo's roots start to grow downward. After that, the stem starts to grow upward and leaves begin to form. Once you can see the plant's leaves, it is a seedling. The environmental factors must also be just right, such as temperature and moisture.
What are three parts of a seed?
Monocotyledonous and dicotyledonous seeds have the following basic structures in common:The Seed coat or testa, protects the embryo against mechanical and chemical damage as well as dessication.The Cotyledon (or cotyledons), provides the food supply for the germinating embryo. The cotyledon(s) eventually develop into the primary leaves on germination of the seed.And the Embryo (or zygote), is the the diploid plant waiting to germinate.
What develops first on a plant?
When a seed germinates the radical emerges first, followed by the leaves
When a seed sprouts into a plant?
When a plant starts to grow from a seed we say the seed germinates.
What is a sentence you can use for the word germinates?
The plant-seed germinates well in burned soil
How can you tell how many seed leaves a plant has?
Depends. - Do you know what kind of plant the seed is from? Look it up. - Can you wait until the seed germinates? Count the initial number of leaves it has as soon as it germinates and before it begins to grow new leaves. - Can you simply dissect the seed? Count how many leaves are on the embryonic plant inside. - Is this a plant that has already germinated and you want to identify (and count) which of its leaves are seed leaves? That's more difficult. Some plants discard their seed leaves within weeks after germination. Some keep them below the soil and only raise their true leaves above the soil. In some plants, the seed leaves are of a markedly different form that the true leaves, but in some (especially pine and related softwood trees) the seed leaves look almost identical to the true leaves.
What is the difference of germination between monocotyledons and dicotyledons?
When a monocot seed germinates a single leaf is produced. Two seed leaves are produced with a dicot germinates.
Where can one find cotyledon in plants?
A cotyledon is found within a seed. It makes up a large portion of the embryo within a seed. It may develop into the first leaves of the plant when it germinates.
What is the life cycle of a plant from a seed?
The seed germinates and the plant grows larger. Plants do not have a life cycle of several stages.
Once a cherry seed germinates what must be done?
You need to plant it.
What is a cotyedon?
If you mean cotyledon, then that is part of the embryo inside of a seed. When the seed germinates it forms the first "leaf" of the plant.
Which sequence shows the order of stages in a plant life cycle?
(1) seed develops inside fruit → seed is dispersed → seed germinates → plant grows (2) seed is dispersed → seed develops inside fruit → seed germinates → plant grows (3) seed germinates → plant grows → seed is dispersed → seed develops inside fruit (4) seed is dispersed → plant grows → seed germinates → seed develops inside fruit The answer is number 1.
When a plant germinates what does it grow?
A seed germinates when it is in a favorable condition, and thus begins to grow a root and a seed leaf. As these two parts continue to grow, the leaf will eventually poke through the soil.
The life cycle of plant?
In the beginning - Seeds How do they grow? - Germination Seeds on the move - Travel A seed germinates, grows, and develops into a plant.
