When a seed germinates (“wakes up”), it begins to grow into a little plant called
a seedling
. It uses the soft fleshy material inside the seed for nutrients (food) until it is ready to make food on its own using sunlight, water and air. Most seeds germinate underground where there is no sunlight.
What plants can you grow from seeds?
It's official:
beans, peas, and pumpkins
are among the top ten easiest plants to grow from seed, according to a list created by the Home Garden Seed Association. Also on the list: cucumbers, zinnias, cosmos, sunflowers, lettuce, radishes, and squash.
What is it called when a plant grows from a seed?
Germination
– the process of growing a new plant from a seed.
What makes a seed grow into a plant?
As it takes up more water, the seed expands and the seed coat cracks open. The embryo inside the seed is made up of
a small shoot and a small root
. The root is the first to emerge from the seed. … Once the shoot, with its one or two seed leaves, emerges from the soil or growing media, we call the plant a seedling.
Can a seed grow into a tree?
The seed contains an embryo – a group of cells ready to form roots, a stem and the first leaves. … Once the coat around the seed is moistened, the embryo cells expand and burst out in a process called germination.
What are the easiest flowers to grow from seeds?

What is the easiest tree to grow from seed?

oaks
, and finding space for one of those in the city can be hard, but crab apples, hazelnuts, rowans, white beans and service trees (Sorbus species) are all easy from seed and suitable for small gardens or allotments (and they'll give you something to eat, too).
What protects the seed of a plant?
Seeds are protected by
a coat
. This coat can be thin or thick and hard. Thin coats don't protect the embryo well. But thick coats can let the embryo survive some tough conditions.
What part of the seed grows first?
root anatomy and function
The primary root, or radicle
, is the first organ to appear when a seed germinates. It grows downward into the soil, anchoring the seedling.
What are the 5 stages of seed germination?
Such five changes or steps occurring during seed germination are:
(1) Imbibition (2) Respiration (3) Effect of Light on Seed Germination(4) Mobilization of Reserves during Seed Germination and Role of Growth Regulators
and (5) Development of Embryo Axis into Seedling.
Do seeds need sunlight to germinate?
Most seeds will not germinate without sunlight
and will perform best with 12 to 16 hours each day. Indoors, place seed containers in a sunny, south-facing window and give the container a quarter turn each day to prevent the seedlings from overreaching toward the light and developing weak, elongated stems.
Why can't all seeds grow into plants?
All seeds
cannot grow into new
plants. … Some seeds do not get sufficient air, water, or warmth to grow. • If the seed survives and gets the right amount of water, air, and warmth (from the sun), it will produce a baby plant or seedling.
How long does it take to grow a tree from seed?
This generally takes
an average of 12 weeks
, but is dependent upon the species. For larger numbers, store the seed in a plastic bag filled with peat or a mixture of equal parts peat and sand or vermiculite. This should be moist but not wet.
How does an apple seed grow into a tree?
It is possible to grow an apple tree from an apple seed. However, in most cases, apple trees don't come true from seeds. … Apple seeds need
to be exposed to cool, moist conditions
before they will germinate. The cool, moist requirement can be accomplished by planting apple seeds outdoors in fall.
What does a seed need to grow answer?
All seeds need
water, oxygen and the right temperature to germinate
. Dormancy is a state of suspended animation in which seeds delay germination until conditions are right for survival and growth.
