A typical seed consists of an embryo, a supply of nutrients for the embryo, and the seed itself. The embryo is the most important part of a seed. During the first few days of life, the fetus is protected from the harsh environment of the womb by a thin layer of amniotic fluid.

This fluid protects the unborn fetus from harmful bacteria and viruses, as well as from other harmful substances that may be present during pregnancy, such as alcohol and tobacco smoke. In the second and third trimesters, however, this protective layer begins to break down.

As a result, bacteria, viruses and other substances can enter the uterus and cause serious health problems, including miscarriage, stillbirth and infant death. For example, a woman who smokes during her pregnancy is not likely to have a miscarriage. However, if she smokes while she is pregnant, she may have an increased risk of developing a serious infection in her uterus.

What three things does a seed contain?

A bean has a seed coat, an embryo, and a cotyledon. The tiny plant is protected by the shell of the seed. The shell protects the embryo from the weather and protects it from predators.” “The shell is a protective covering for the plant. It is made of keratin, the same material that makes up fingernails and toenails.

What do seeds contain and why?

All fully developed seeds contain an embryo and, in most plant species, a store of food reserves, wrapped in a seed coat. When the soil is moist and the temperature is right, seeds will wake up and grow.

Seeds can be stored for a long period of time by storing them in moist, dark, well-drained soil. They can also be kept in the refrigerator for up to a year, but this is not recommended for long-term storage because the seeds can become moldy and lose their nutritional value.

What does a seed contain Ka answer?

A future plant or embryo that develops into a seedling is contained in the seed. A seed contains an embryo or plant that grows into a plant. Seed is a type of seed that can be used to produce a variety of plants and animals. Seeds are produced by the process of germination. Germination occurs when a seed germinates in a warm, moist environment such as soil, water, or air.

The seed is then exposed to the environment for a period of time. During this time, the seed begins to divide and produce seeds. Each seed has a unique genetic code that determines the characteristics of the plant and animal that will grow from it. In the case of seeds, these characteristics are determined by a number of genes that are located on the chromosomes of each individual seed. These genes are called alleles.

For example, an allele is the combination of two or more genes. An allele may be a single gene or it may have multiple genes in the same gene. A gene may also be called a locus, a region of DNA that is located at a specific location on a chromosome. Genes are also called loci because they are found at specific locations on each chromosome of an organism.

What do seeds contain quizlet?

An embryo is a single cell that develops into a fetus. A seed is an organism that has been fertilized by a sperm or an egg, and is capable of developing into an adult organism. If you are pregnant, your doctor will ask you questions about your menstrual cycle and other symptoms. You may also be asked to take a pregnancy test.

If the test comes back positive, you will be told that you have been pregnant for at least 12 weeks. Your doctor may order an ultrasound to determine the size and shape of your unborn baby. The ultrasound may show that your baby has a head, arms, legs, or other body parts, but it will not tell you if the baby is male or female.

What does a seed contain Class 5?

The embryo and cotyledons are inside the seed. What is the difference between a seedling and an embryo? (a) Seedlings are small, green plants that grow in the soil. The difference is that the embryo is a small plant, while the seeds are larger and more mature.

What 3 things does a seed need to grow?

The seeds need water, oxygen and the right temperature to grow. In a state of suspended animation, seeds are delayed in germinating until conditions are right for them to grow. Seeds can also be dormant for long periods of time.

This is called dormancy and is caused by a number of factors, including temperature, humidity, light and nutrients. Seeds that are dormant will not grow, but they will continue to produce seeds until they are exposed to light, nutrients or temperature changes that cause the seeds to become dormant again.
