What are the stages of seed development?
Imbibition: the seed intakes water, swells, and extends its first root (radicle) Dormancy: the seed digests the nutrition inside of it and sprouts. Growth: the seed grows exponentially into adulthood.
What happens after seed formation?
Following the fertilization, every part of the flower sheds off except ovary. The ovary of the flower develops into the fruit while ovules develop into seeds. The formation of seed completes the process of reproduction in plants. Within the seed, the growing embryo develops and matures.
What are the 5 steps of germination?
The process of seed germination includes the following five changes or steps: imbibition, respiration, effect of light on seed germination, mobilization of reserves during seed germination, and role of growth regulators and development of the embryo axis into a seedling.
What is development of new seed?
In angiosperms, the process of seed development begins with double fertilization and involves the fusion of the egg and sperm nuclei into a zygote. The second part of this process is the fusion of the polar nuclei with a second sperm cell nucleus, thus forming a primary endosperm.
What are the 5 stages of plant growth?
They follow a cyclic process of starting a new life, growing, and then coming back to the starting stage (reproducing). There are the 5 stages of plant life cycle. The seed, germination, growth, reproduction, pollination, and seed spreading stages.
What are the 3 stages of seed development?
Seed development in flowering plants proceeds in three discrete, although continuous, stages: early, mid-, and late embryogenesis.
What develops into a seed after fertilization?
After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.
How do seed grain develop?
Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule.

What are the 4 stages of germination?
The Seed Germination Process :
- Imbibition: water fills the seed.
- The water activates enzymes that begin the plant's growth.
- The seed grows a root to access water underground.
- The seed grows shoots that grow towards the sun.
- The shoots grow leaves and begin photmorphogenesis.
What are the 7 stages of plant growth?

What happens to seed after fertilization?

What will happen after fertilization?
Implantation. Once the embryo reaches the blastocyst stage, approximately five to six days after fertilization, it hatches out of its zona pellucida and begins the process of implantation in the uterus. In nature, 50 percent of all fertilized eggs are lost before a woman's missed menses.
What is the first step in seed formation?
Pollination is the first step in seed formation. Pollination is done by bees & insects. Then pollen tube forms which transfer male gametes to the ovules in ovary. Then male gametes & ovule fuses to form zygote which further develops into a fruit.

Germination is a fundamental process carried out by all higher plants. In this process, a seed is allowed to mature, germinate and to produce into new plantlets.
How can you have a girl?
There's only one guaranteed way to conceive a girl, which is a procedure known as sex selection. This in vitro fertilization method (IVF) involves implanting a girl or boy embryo into the mother's uterus. This option, however, is expensive, and even illegal in some countries.
What are the 4 steps of fertilization?
asymmetric and motile sperm cell and a large and nonmotile egg. The stages of fertilization can be divided into four processes: 1) sperm preparation, 2) sperm-egg recognition and binding, 3) sperm-egg fusion and 4) fusion of sperm and egg pronuclei and activation of the zygote.
What are the 7 stages of plant life cycle?
The major stages of the flower life cycle are the seed, germination, growth, reproduction, pollination, and seed spreading stages.
What is the life cycle of a seed?
The plant life cycle consists of four stages; seed, sprout, small plant, and adult plant. When the seed gets planted into the soil with water and sun, then it will start to grow into a small sprout.
How does a plant grow step by step?
The stages that plants go through are from seed to sprout, then through vegetative, budding, flowering, and ripening stages. Similarly, the nutritional needs of people and plants change as they grow.

How can I make my wife pregnant after marriage?
You're most likely to get pregnant if you have sex in the days around ovulation (when an egg is realised from the ovary), with the day before and day after being the most fertile. An egg lives for about 12-24 hours after being released. The egg must be fertilised by a sperm during this time for you to get pregnant.
