What is germination in plant reproduction?
Sexual reproduction in plants happens in a cycle-like pattern. Germination is the process by which a plant begins to grow from a seed. Roots form under the soil. The stem, leaves and flower emerge above the soil. Pollen produced by a flower is carried by insects or blown by the wind to another flower.
How do you explain germination to a child?
Germination is the phase of plant growth when the seed begins to sprout. Seeds have a seed coat, a protective layer on the outside. Inside the seed there is a cotyledon that protects and provides food for the baby plant, and the embryo, the baby plant inside the seed that has roots, a stem, and leaves.
How do seeded plants reproduce?
Plants that reproduce by seeds. Seed plants have special structures on them where male and female cells join together through a process called fertilisation. The parent plant disperses or releases the seed. If the seed lands where the conditions are right, the embryo germinates and grows into a new plant.
What happens during germination of a seed?
In the process of seed germination, water is absorbed by the embryo, which results in the rehydration and expansion of the cells. Shortly after the beginning of water uptake, or imbibition, the rate of respiration increases, and various metabolic processes, suspended or much reduced during dormancy, resume.

What happens when a plant seed germinates?
Seed Life Cycle: Germination Once germination occurs, the new plant will gradually begin to emerge. The root, which anchors the plant to the soil, grows downward. This also enables the plant to take up the water and nutrients required for growth. The shoot then grows upward as it reaches for the light.
What are the steps in plant germination?
The Seed Germination Process
- Step 1: Imbibition: water fills the seed.
- Step 2: The water activates enzymes that begin the plant’s growth.
- Step 3: The seed grows a root to access water underground.
- Step 4: The seed grows shoots that grow towards the sun.
- Step 5: The shoots grow leaves and begin photmorphogenesis.
What is the reproductive part of the seed?
A number of parts of the reproductive process are common to both angiosperms and gymnosperms: (1) they produce seeds at maturity; (2) the megasporangium, unlike that of heterosporous seedless plants, is covered by one or two cellular layers called integuments and is termed an ovule; (3) there is a minute passageway, or …
What are some fun facts about seed germination and reproduction?
Fun Facts about Germination and Reproduction of Plants for Kids. All seeds need moisture, oxygen and the right temperature to germinate, or grow. Until they have these conditions, the seed remains dormant and does nothing. Some seeds need light to germinate. Others need darkness. Once the seeds have the right conditions,…
What is germination in plants?
Germination is the phase of plant growth when the seed begins to sprout. Seeds have a seed coat, a protective layer on the outside. Inside the seed there is a cotyledon that protects and provides food for the baby plant, and the embryo, the baby plant inside the seed that has roots, a stem, and leaves.
What is the first step in germination?
Steps of Germination When conditions are right the seed starts to take in water. As water is taken in, the seed swells bigger and bigger until the coat splits apart. Air can then get to the seed. So, the oxygen in the air helps the baby plant burn the food packed inside the seed. Burning the food produces energy.
What is the plant life cycle for kids?
Let’s understand more about plant life cycle for kids. ➤ 1. Seed – The plant life cycle starts with a seed. From the outside, seeds are protected by a tough layer, called Outer Coat. But inside every seed, there is a tiny baby plant, known as an embryo. The embryo has a root, shoot as well as the first true leaves.
