Identify the sentence if true or false. 1. A plant needs water, air, and sunlight to germinate. 2. Sunlight are warmth are not required for germination. 3. Sunlight and soil are not required for germination. 4. A seedling develops into a seed 5. A seedling is a young plant developing out of a plant embryo from a seed.
The correct answer and explanation is:
Here are the answers to the statements with explanations:
- A plant needs water, air, and sunlight to germinate.
False
During germination, a seed primarily requires water, oxygen (air), and the right temperature. Sunlight is not necessary for the seed to germinate. The seed uses stored food to start growing before it becomes a seedling. Sunlight becomes important after germination for photosynthesis, but not for the germination process itself. - Sunlight and warmth are not required for germination.
False
While sunlight is not essential for germination, warmth (or a suitable temperature) is important. Seeds need the right temperature range to activate enzymes that start the growth process. If it is too cold or too hot, germination may be slow or fail. - Sunlight and soil are not required for germination.
True
Sunlight is not required for germination because seeds rely on stored nutrients to begin growth. Soil is not strictly necessary either; seeds can germinate on moist paper towels or other mediums as long as water, oxygen, and temperature are adequate. - A seedling develops into a seed.
False
A seedling does not develop into a seed. Instead, a seed develops into a seedling after germination. The seedling is the young plant that grows and eventually matures into a full plant. The plant will later produce seeds as part of its reproductive cycle, but seedlings do not turn back into seeds. - A seedling is a young plant developing out of a plant embryo from a seed.
True
This is the correct definition. A seedling is the early stage of a plant that emerges after germination. It develops from the embryo inside the seed and will continue growing into a mature plant.
Explanation:
Germination is the process by which a seed begins to grow and develop into a seedling. For germination to occur, the seed must absorb water to activate metabolic processes. Oxygen is needed for respiration, which supplies energy for growth. Temperature plays a key role because enzyme activity depends on it. Although sunlight is vital for photosynthesis after the seedling emerges, it is not necessary for the seed to start growing. Soil provides nutrients and support but is not strictly required at the germination stage if other conditions are met. After germination, the seedling grows, develops leaves, and eventually matures into a full plant capable of producing new seeds, continuing the life cycle.
