What is the name for the growth of a plant embryo from a seed?
Germination.
What is pollen tube germination?
Pollen tube germination is the process by which a pollen grain, upon landing on a compatible stigma, develops a tube that extends down the style toward the ovule in the ovary. This tube carries sperm cells from the pollen grain to fertilize the ovule, leading to seed formation. The germination process involves the hydration of the pollen grain and the growth of the tube, which is guided by chemical signals from the ovule. Successful germination is crucial for plant reproduction.
What is hypogeal germination?
Hypogeal germination is a type of seed germination where the cotyledons remain below the ground after germination. The stem elongates to bring the cotyledons and leaves above the soil surface. This type of germination is common in dicot plants.
Define and explain types of germination?
There are three types of germination 1.Hypogeal germination and epigeal germination and Cleistogeal germination. Hypogeal Germination: In this kind of Germination, the seed leaves or the cotyledons remain under the surface of soil. example: pea seeds - Epigeal Germination: In this type of Germination, the seed leaves grow above the ground on the new shoot. example: ash tree -Cleistogeal Germination: A special leaf that has a central umbrella like stalk forms above the ground which protects the shoot from any damage. So the development of the shoot can not be seen.
What steps just occur for a seed to grow into a new plant List the steps in sequence?
germination
What factor starts germination?
it is the factor when the embryo signals for water.
What signals the end of germination and the beginning of the plants growth?
The end of germination is signaled by the emergence of the plant shoot above the soil surface, and the beginning of growth is marked by the development of leaves and the expansion of roots to uptake nutrients from the soil. This transition is crucial for the plant to start photosynthesis and establish itself in its environment.
How will sunlight affect cress seeds to grow?
Sunlight signals for germination of cress seeds
What signals a seed to awake?
Seeds are typically triggered to germinate by a combination of factors such as water availability, temperature, and light exposure. These environmental signals activate different physiological processes within the seed that lead to germination.

What is the name for the growth of a plant embryo from a seed?
Germination.
How does pollution affect germination?
The toxins and harmful bacteria in the pollution stops or slows the germination process. Also the plant could still grow but turn out to be a bad or harmful product in the end.
What does 'menopause' mean?
It signals the end of a female's menstruating and end of fertility.
What should be the conditions of germination?
Germination conditions typically include moisture, oxygen, proper temperature, and sometimes light. Seeds need adequate water to soften the seed coat and activate enzymes for growth, oxygen for respiration to provide energy, suitable temperature for enzyme activity, and in some cases, light signals for the seeds to start growing.
What is the final action signals the end of the Olympic games?

What is the name given when seeds produce tiny shoots and roots?
Germination.
