Why is light only necessary one the plant has germinated?
Light is necessary for plants after germination because it is required for the process of photosynthesis, which produces energy for the plant to grow. Before germination, the seed relies on stored nutrients for initial growth. Once the seed germinates and starts to photosynthesize, it needs light to continue producing energy for development and maintenance.
How does a seed become a plant in kids form?
A seed needs water, light, and warmth to germinate. Once germinated, it develops roots to absorb water and nutrients from the soil, while the shoot grows towards the light. Leaves start to form, allowing the plant to carry out photosynthesis and grow. Over time, the plant matures and can produce its own seeds to start the cycle again.
Which would grow faster germinating or non- germinated seeds?
Germinating seeds grow faster than non-germinated seeds because they are actively undergoing the processes of growth and development. Germination initiates metabolic activities that lead to root and shoot formation, enabling the plant to access water and nutrients. In contrast, non-germinated seeds remain dormant and do not grow until conditions are favorable for germination. Therefore, once germination occurs, the seedling begins to grow rapidly compared to unactivated seeds.
Why would un-germinated seeds show less respiration?
Un-germinated seeds have lower respiration rates because they are in a dormant state and do not require as much energy. Once germination begins, the metabolic activity increases, leading to higher respiration rates as the seed begins to grow and develop.
Why do seeds not need light right away?
Seeds contain all the necessary nutrients and energy to begin germination without needing light. The initial stages of germination involve the absorption of moisture to activate metabolic processes, rather than photosynthesis. Once the seed has sprouted and developed leaves, light becomes essential for photosynthesis to provide the plant with energy.

Why do growing seeds need to be watered once they have germinated?
To establish a root system and nourish the plant. The roots will absorb the water and nutrients to nourish the plant so it will grow.

How much light intensity is needed to grow a tomato plant once it has germinated?
Tomato plants require a minimum of 6-8 hours of full sun per day, which equates to approximately 10,000-20,000 lux of light intensity. Providing adequate light is crucial for healthy growth and fruit production. If growing indoors, consider using grow lights to ensure the plant receives the necessary light intensity.
What a plant needs to grow?
The components needed for the intial germination of a seed are simply water, oxygen and lack of light (hence soil is ideal). However once the seed has germinated and is established asa seedling or plant then its requirements for sustained life change. In order for a plant to survive it needs to fulfil the requirements of photosynthesis, that is sunlight+CO2+water=oxygen+sugar Therefore a plant requires direct sunlight, sufficient water and presence of Carbon Dioxide to survive.
What is an ovary in a plant?
Its something to do with pollen going down the style into the ovary to be germinated. It is also a place where the egg or the ovule devolops.
What is the effect of light on mung bean germination?
Light is not necessary for mung bean germination, as these seeds germinate well in the dark. In fact, excessive light can hinder germination by affecting the production of certain hormones required for the process. Once the seeds have sprouted and started to grow, light becomes essential for photosynthesis and further development of the plant.
The conditions for seed germination and plant growth are different Explain why?
Seed germination requires specific conditions such as adequate moisture, oxygen, and favorable temperature for the seed to break dormancy and start growing. Once the seed has germinated and the plant has started to grow, different factors like nutrient availability, light exposure, and optimal pH levels become important for continued growth and development. In summary, while seed germination focuses on breaking dormancy and initiating growth, plant growth involves ongoing processes that require nutrients, light, and other factors for healthy development.
What is the advantage of planting using seedbox?
Not every seed will germinate. Sowing lots of seeds in a seedbox is quicker than planting a single or a small number of seeds in small individual plant pots; especially if the seeds are extremely tiny. Once the seeds have germinated, any healthy and robustly growing seedlings can be pricked out and potted on into individual plant pots.
What plants have to start photosynthesis?
By definition, all plants have to use photosynthesis. This begins once light reaches the plant.
Why would un-germinated seeds show less respiration?
Un-germinated seeds have lower respiration rates because they are in a dormant state and do not require as much energy. Once germination begins, the metabolic activity increases, leading to higher respiration rates as the seed begins to grow and develop.
After germinating the seeds and then placed in the soil Do you need to place it in light or wait until it sprouts out of the soil?
After planting the germinated seeds in the soil, it's best to place them in a location with adequate light. This will help the sprouts grow strong and healthy. Waiting until they sprout out of the soil before providing light may result in leggy and weak seedlings.
