Plant Life Cycle /Seed Germination

The video tutorial explores the life cycle of vascular plants, focusing on key stages such as seed structure, germination, and photosynthesis. It explains the roles of vascular tissues like xylem and phloem in nutrient transport. The process of plant reproduction, including pollination, is also covered, highlighting the importance of creating offspring for the next generation.

What is the primary function of xylem in vascular plants?

• Protecting the plant from physical harm

• Transporting water and nutrients from roots

• Facilitating pollination

• Transporting sugars produced by photosynthesis

Which part of the seed acts as food for the embryo during germination?

• Seed coat

• Embryo

• Phloem

• Endosperm

What triggers the process of germination in a seed?

• Presence of sucrose

• Access to water and air

• Contact with pollinators

• Exposure to sunlight

What is the main purpose of photosynthesis in plants?

• To protect the plant from predators

• To produce seeds

• To transport water through the plant

• To synthesize food using sunlight

How does pollination occur in plants?

• Through the absorption of water

• By the growth of the seed coat

• By the fusion of xylem and phloem

• Via pollen grains moving from anther to stigma
