Q: What are modified roots, and can you give an example?
A: Modified roots are roots that perform special tasks. An example is aerial roots, like those found in old banyan trees, which provide support to the tree.
Q: What is the function of the stem in plants?
A: The stem supports the upper parts of plants, carries water and nutrients from roots to leaves, and transports food produced by the leaves to other parts of the plant.
Q: What are tendrils and what is their purpose?
A: Tendrils are coil-like structures modified from stems or leaves. They help weak plants climb up and grow by taking support from other structures.
Q: What is chlorophyll and why is it important?
A: Chlorophyll is a green pigment present in leaves. It’s important because it uses the energy in sunlight to turn water and carbon dioxide into sugar and oxygen during photosynthesis.
Q: How do desert plants like cacti adapt to their environment?
A: Desert plants like cacti often have modified leaves in the form of spines to reduce water loss, and some have water-storing stems.
Q: What is the difference between sepals and petals?
A: Sepals are usually small and green, composing the outermost part of a flower and protecting the bud. Petals are often brightly colored or unusually shaped to attract pollinators.
Q: What is the ovary in a flower, and what does it become?
A: The ovary is part of the pistil located at the bottom of the style. After pollination, it usually becomes the fruit.
Q: How do seeds of plants like dandelions disperse?
A: Dandelion seeds develop very light and fluffy parachute-like structures that help them float in the wind and disperse over long distances.
Q: What is explosive dispersal in plants?
A: Explosive dispersal is a method where plants distribute their seeds by ejecting them with force when dried in the sun. Plants in the Pea Family are an example of this.
