FAQs on Flashcards: Plant Life

Question 1

1. What are the main parts of a plant and what does each part do?

Accepted Answer

Ans. Plants have five main parts: roots absorb water and nutrients from soil, stems transport these materials upward and provide support, leaves make food through photosynthesis, flowers produce seeds for reproduction, and fruits protect seeds. Each part works together to keep the plant alive and healthy, helping it grow and reproduce successfully.

Question 2

2. How do plants make their own food using sunlight?

Accepted Answer

Ans. Plants manufacture food through photosynthesis, a process occurring in leaves containing chlorophyll. During this process, plants use sunlight, water from roots, and carbon dioxide from air to create glucose (sugar) for energy. Oxygen is released as a byproduct. This is why plants need light, water, and air to survive and grow properly.

Question 3

3. What's the difference between germination and growth in plants?

Accepted Answer

Ans. Germination is when a dormant seed awakens and begins sprouting into a seedling-it's the initial stage lasting days or weeks. Plant growth follows germination and continues throughout the plant's life, involving increasing size, developing more leaves, and strengthening roots and stems. Germination is a one-time event; growth is continuous and ongoing.

Question 4

4. Why do plant roots grow downwards while stems grow upwards?

Accepted Answer

Ans. Roots exhibit positive gravitropism, meaning they grow towards gravity (downwards) to access water and minerals in soil efficiently. Stems show negative gravitropism, growing away from gravity (upwards) to reach sunlight for photosynthesis. This directional growth pattern ensures plants optimise resources-roots for nutrients, stems for light exposure needed for survival.

Question 5

5. What are the different types of flowers and how do they help in plant reproduction?

Accepted Answer

Ans. Flowers contain male parts (stamens producing pollen) and female parts (pistils producing ovules). Different flower types attract specific pollinators like bees and butterflies through colour, scent, and nectar. When pollen reaches the pistil, fertilisation occurs, creating seeds and fruits. Flowers are essential reproductive structures enabling plants to create next-generation offspring successfully.
