FAQs on Plants in Forests Video Lecture - Science Class 7 (Old NCERT)

1. What are the different types of plants found in forests?

Ans. Forests are home to various types of plants, including trees, shrubs, herbs, and climbers. Trees are the dominant plants in forests and they provide shade, shelter, and food for many animals. Shrubs are smaller than trees and grow closer to the ground. Herbs are non-woody plants that have soft stems, and climbers are plants that use other plants or structures for support as they grow upwards.

2. How do plants in forests contribute to the ecosystem?

Ans. Plants in forests play a crucial role in the ecosystem. They produce oxygen through photosynthesis, which is essential for the survival of all living beings. Forest plants also provide habitat and food for a wide variety of animals, birds, and insects. They help in maintaining the water cycle by absorbing and releasing water vapor through transpiration. Additionally, forest plants help in preventing soil erosion and act as carbon sinks, reducing the impact of climate change.

3. What are some examples of plants that can be found in tropical rainforests?

Ans. Tropical rainforests are known for their incredible biodiversity. Some examples of plants found in tropical rainforests include giant trees like the Kapok tree and the Brazil nut tree, epiphytes like orchids and bromeliads that grow on other plants, carnivorous plants like pitcher plants and Venus flytraps, and various types of ferns and mosses. These plants have adapted to the unique conditions of the rainforest, such as high humidity and limited sunlight.

4. How do plants in forests reproduce?

Ans. Plants in forests reproduce through various methods. Trees and shrubs typically reproduce through both sexual and asexual methods. Sexual reproduction involves the transfer of pollen from the male reproductive organs to the female reproductive organs, leading to the formation of seeds. Asexual reproduction, on the other hand, involves the growth of new plants from vegetative parts like stems or roots. Some plants in forests also rely on animals, wind, or water for pollination and seed dispersal.

5. What are the threats faced by plants in forests?

Ans. Plants in forests face numerous threats, including deforestation, habitat destruction, climate change, and invasive species. Deforestation involves the clearing of forests for agriculture, logging, or urbanization, which leads to the loss of plant species and their habitats. Habitat destruction occurs due to activities like mining, construction, and pollution. Climate change affects forest plants by altering temperature and rainfall patterns. Invasive species can outcompete native plants and disrupt the balance of the forest ecosystem. Conservation efforts are crucial to protect and preserve the plants in forests.
