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.
The first part of a seed to emerge is a small sprout called the radical, which will develop to form the root system of the new plant. The first above-ground part is a stem containing the cotyledons (either one or two depending on the plant type); these resemble small leaves, but will drop off once true leaves have developed.
The first root that grows from a seed is called the radicle. It is the primary root of the plant and is responsible for anchoring the plant in the soil and absorbing water and nutrients.

What is the first thing a seed will grow?
The root.
What part of a seed comes first?
search up cotyledon :) Edited answer: When a seed sprouts, it is the radicle of the embryo comming out first.
What grows out of the grass seed first stem root?
The first thing to grow out of a grass seed is usually the primary root, also known as the radicle. This root system helps anchor the seedling in the soil and begins to absorb water and nutrients for growth. Soon after, the shoot emerges from the seed, developing into the stem and leaves of the plant.
Where does the seed get the food to begin growing the root?
The seed contains stored food reserves in the form of starch and proteins. When the seed germinates, enzymes break down these reserves to provide energy for the developing root until it can begin photosynthesis and produce its own food.
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.
What are the growing parts of the plant?
The first part of a plant to grow is the root. The mesocotyle of the seed can be differentiated into epicotyle and hypocotyle.
What is the first thing a seed will grow?
The root.
What grows out of a sunflower seed first?
The root.
What part of a seed comes first?
search up cotyledon :) Edited answer: When a seed sprouts, it is the radicle of the embryo comming out first.
What is the function of a radicle?
It's the embryonic root inside the seed. It's the first thing to emerge out of a seed and down into the ground to allow the seed to suck up water and send out its leaves so that it can start photosynthesizing.
What is the first part to emerge from a germinating seed?
The radicle is the first part to emerge from a germinating seed. It is the embryonic root that grows downward into the soil to anchor the plant and absorb water and nutrients.
What the first structure to emerge from the seed?
The first structure to emerge from a seed is typically the radicle, which is the embryonic root of the plant. It grows downward into the soil to anchor the plant and absorb water and nutrients.
Which part of the embryo comes out first during seed germination?
The radicle, which develops into the root system of the plant, is the first part of the embryo to emerge during seed germination.
What grows out of the grass seed first stem root?
The first thing to grow out of a grass seed is usually the primary root, also known as the radicle. This root system helps anchor the seedling in the soil and begins to absorb water and nutrients for growth. Soon after, the shoot emerges from the seed, developing into the stem and leaves of the plant.
Where does the seed get the food to begin growing the root?
The seed contains stored food reserves in the form of starch and proteins. When the seed germinates, enzymes break down these reserves to provide energy for the developing root until it can begin photosynthesis and produce its own food.
Which part of the seed becomes the first stem?
There are three structures that appear from the seed: the radical, the hypocotyls and the plumule. The first structure to appear from the seed is the radical, which is the root and grows downward into the soil.
Why a seed always develop its roots first?
A seed does NOT always develop its roots first. The sprout that first emerges from a seed is actually the part that will develop above ground if the seed is planted in the ground. The root develops once this sprout begins to shed its seed casing.
