The Journey of Seeds from Germination to Growth

The video explains the structure of seeds, including the embryo, food store, and seed coat. It describes the germination process, highlighting the role of enzymes and the need for sunlight, water, oxygen, and warmth. The video details how seeds absorb water, swell, and develop roots and shoots. It emphasizes the importance of photosynthesis for plant growth, explaining how plants use carbon dioxide, water, and light to produce oxygen and glucose. The video concludes with an invitation to learn more about photosynthesis.

What is the role of the embryo in a seed?

• To absorb water

• To protect the seed

• To store food

• To grow into an adult plant

Which of the following is NOT a factor required for seed germination?

• Sunlight

• Water

• Carbon dioxide

• Oxygen

What happens to the seed coat during the initial stages of germination?

• It hardens

• It becomes soft and swells

• It absorbs nutrients

• It changes color

Why is oxygen important for a germinating seed?

• For water transport

• For aerobic respiration

• For photosynthesis

• For nutrient absorption

What is the primary function of the root during germination?

• To produce flowers

• To search for water and nutrients

• To carry out photosynthesis

• To store food

Which part of the plant grows towards light and air?

• Cotyledon

• Seed coat

• Shoot

• Root

What is the main purpose of photosynthesis in plants?

• To produce oxygen and glucose

• To store starch

• To protect the plant

• To absorb water

What happens to the cotyledon once the plant can photosynthesize?

• It turns into a flower

• It remains as a food store

• It becomes a leaf

• It falls off and becomes part of the soil

What are the end products of photosynthesis?

• Carbon dioxide and water

• Oxygen and glucose

• Starch and oxygen

• Water and glucose
