Why do the cotyledons fall off?
Cotyledons fall off once the plant starts producing its own energy through photosynthesis. The cotyledons were initially providing nutrients to the growing seedling, but once the plant becomes self-sufficient, they are shed as they are no longer needed. This allows the plant to focus its energy on further growth and development.
Do pea seeds undergo hypogeal germination?
Yes, pea seeds undergo hypogeal germination, where the cotyledons remain below the ground while the shoot emerges above the soil surface. This type of germination allows the cotyledons to provide nutrients and support for the emerging seedling.
An embryo plant whose root and stem have stated growing is called what?
An embryo plant whose root and stem have started growing is called a seedling.
What is it called when a embryo's stems and roots have started growing?
SEEDLING
What is a young plant growing from a seed is called?
A young plant growing from a seed is called a seedling. Seedlings typically have their first set of true leaves and are beginning to establish roots.

Why are cotyledons important in a eudicot seed?
Cotyledons are important in a eudicot seed because they serve as the first leaves of the plant embryo, providing stored nutrients for the seedling's initial growth until it can independently photosynthesize. They also aid in absorbing and transferring nutrients from the endosperm or stored reserves to the growing seedling.
Do pea seeds undergo hypogeal germination?
Yes, pea seeds undergo hypogeal germination, where the cotyledons remain below the ground while the shoot emerges above the soil surface. This type of germination allows the cotyledons to provide nutrients and support for the emerging seedling.

What is the tiny young plant growing from a seed?
It is called the seedling.
What is a young plant growing from a seed is called?
A young plant growing from a seed is called a seedling. Seedlings typically have their first set of true leaves and are beginning to establish roots.
Where does the food needed for a seedling to start to grow come from?
The food needed for a seedling to start growing comes from the seed itself. Inside the seed, there are stored nutrients such as carbohydrates, proteins, and fats that provide energy and nutrients for the seedling to germinate and begin growing until it can photosynthesize on its own.
Is barley epigeal?
Yes, barley (Hordeum vulgare) is considered an epigeal germinator. In epigeal germination, the cotyledons (seed leaves) emerge above the soil surface during seedling development. This characteristic helps barley establish itself quickly in its growing environment, allowing for effective photosynthesis as it grows.
What happens to a bean seedling that has started growing then gets put in the dark?
A bean seedling kept in dark develops chlorosis and its leaves become yellow.
What is the first root first growing from a seed?
they will begin to develop leaves, and are then known as baby greens. A popular baby green is sunflower after 7-10 days. seedling - a young plant sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves). The two classes of flowering plants are distinguished by their numbers of seed leaves: Monocotyledons (monocots) have one blade-shaped cotyledon, whereas dicotyledons (dicots) have two round cotyledons. Gymnosperms are more varied. For example, pine seedlings have up to eight cotyledons. The seedlings of some flowering plants have no cotyledons at all. These are said to be acotyledons. During germination, the young plant emerges from its protective seed coat with its radicle first, followed by the cotyledons. The radicle orients towards gravity, while the hypocotyl orients away from gravity and elongates through cell expansion to push the cotyledons out of the ground. Once the seedling starts to photosynthesize, it is no longer dependent on the seed's energy reserves. The apical meristems start growing and give rise to the root and shoot. The first "true" leaves expand and can often be distinguished from the round cotyledons through their species-dependent distinct shapes. While the plant is growing and developing additional leaves, the cotyledons eventually senesce and fall off.
What happen to a germinating seed?
The contents of a seed are used up after germination by the seedling growing from it.
