Test: Seeds and Seeds - 2 - Class 5 MCQ

• Seeds need the right amount of water to sprout. Without enough water, they remain dry and do not activate the enzymes required for sprouting.
• The water softens the seed coat and provides the energy needed for the growth of the seedling.

• Soyabean seeds spread to new locations when their ripe pods burst open, forcefully ejecting the seeds.
• This mechanism allows the seeds to scatter and find suitable environments for germination and growth.

• Potatoes and tomatoes were among the vegetables brought to India from other countries.
• These introductions have since become integral parts of Indian cuisine, highlighting the impact of human migration and trade on global agricultural diversity.

• Soaked seeds typically take 2-3 days to sprout depending on the temperature and humidity.
• The process of sprouting converts the stored starch into simpler sugars, making it easier to digest.

• Velcro was inspired by seeds with tiny hooks that stuck to George Mestral's clothes and his dog's fur, leading to the invention of a material with similar hooks.
• The seeds did not fly but were carried by animals or attached to surfaces.

• The pitcher plant is a type of carnivorous plant that traps insects.
• The mouth of the pitcher plant is actually a modified leaf.
• This leaf forms a deep cavity filled with digestive fluids.
• The structure is designed to lure, trap, and digest insects.
• The leaf acts as a lid, preventing rainwater from diluting the digestive juices inside the pitcher.

Hence, Correct Answer is Option C

• Light seeds such as cumin and aniseed (saunf) are characterized by their ability to be blown away easily when air is blown over them.
• This property allows them to disperse and spread over long distances, which is why they are classified as light seeds.

• When masoor dal is split, the seed coat is removed.
• The seed coat is important because it protects the baby plant (embryo) inside the seed.
• The seed coat also helps the seed absorb water and get nutrients, which are needed for sprouting.
• Without the seed coat, split masoor cannot sprout or grow into a new plant.
• Hence, correct answer is Option B

• Soaking seeds or grains makes them absorb water, softening them and reducing cooking time.
• It also aids in digestion by breaking down certain components.
• This method has been used for centuries in various cultures!

• Potato: Potatoes reproduce through tubers, which are vegetative structures. They do not need seeds for propagation.
• Orange: Oranges typically reproduce through seeds or grafting. They do not primarily reproduce without seeds.
• Banana: Bananas reproduce mainly through suckers or rhizomes, not seeds.
• So, the plants that can grow without seeds are Potato and Banana

Given the options, the correct answer is:Option D
