from a single parent, inheriting only the
parent's characteristics, resulting in exact
copies of the parent plant.

the body parts of a plant
such as the stem, roots and
leaves is called vegetative
propagation.

FAQs on PPT: Plant Life

1. What are the main parts of a plant and what do they do?
Ans. Plants have five main parts: roots absorb water and nutrients from soil, stems transport these materials upward and provide structure, leaves perform photosynthesis to make food, flowers produce seeds for reproduction, and fruits protect seeds. Each part has a specific function essential for plant survival and growth.
2. How does photosynthesis work and why do plants need sunlight?
Ans. Photosynthesis is the process where plants use sunlight, water, and carbon dioxide to create their own food (glucose) and release oxygen. Sunlight provides the energy plants need to convert raw materials into nutrients. Without light, plants cannot manufacture food and will eventually weaken and die.
3. What's the difference between roots and stems, and why does each matter for plant growth?
Ans. Roots grow downward into soil to anchor plants and absorb water plus minerals, while stems grow upward to support leaves and transport resources. Roots are underground storage and nutrient-collection systems, whereas stems distribute those resources throughout the plant. Both are critical for survival and structural strength.
4. Why do some plants have flowers and others don't, and what's the purpose of flowers anyway?
Ans. Flowering plants reproduce through flowers, which contain reproductive organs that produce seeds after pollination. Non-flowering plants like ferns and mosses reproduce using spores instead. Flowers attract pollinators (bees, butterflies) to transfer pollen between plants, enabling sexual reproduction and genetic diversity in plant populations.
5. What are the different types of plant life cycles and how do annual, biennial, and perennial plants differ?
Ans. Annual plants complete their entire life cycle-germination, growth, flowering, seed production, and death-in one year. Biennials take two years, storing energy in roots during year one before flowering in year two. Perennials live three or more years, surviving winters and regrowing each season. Each strategy helps plants adapt to their environment.
