Explanation

Androecium is the collective term for the male reproductive parts of a flower, called stamens.

Each stamen typically consists of an anther (pollen-producing) and a filament.

Explanation

Xylem transports water and dissolved mineral salts upward from the roots to the leaves.

It plays a key role in plant hydration and nutrient distribution for photosynthesis.

Explanation

Green plants make their own food through photosynthesis, so they are called producers.

They form the base of the food chain in any ecosystem.

Explanation

In dicot seeds, cotyledons store nutrients that nourish the growing embryo.

They often also help in the early stages of photosynthesis after germination.

Explanation

Tea plants require high rainfall and humid climate for healthy growth.

They grow well in hilly or sloped regions with fertile, well-drained soil.

Explanation

Asexual reproduction in plants is commonly referred to as vegetative propagation or vegetative reproduction.

It involves the formation of new plants from parts of the parent plant, like stems, roots, or leaves, without the involvement of seeds.

Explanation

Centrioles are present only in animal cells.

They are involved in cell division (spindle formation).

Higher plant cells typically lack centrioles and instead organize their spindle fibers differently.

Explanation

Water is essential for survival as it supports biological functions in humans, animals, and plants.

It is needed for digestion, circulation, photosynthesis, and maintaining life processes.

Explanation

During respiration, plants break down glucose to release energy (ATP), producing carbon dioxide and water as byproducts.

This process occurs in the mitochondria.

It happens day and night.

Explanation

Earthworms improve soil fertility by decomposing organic matter, making nutrients available to plants.

They enhance soil aeration and structure, acting as natural bio and living fertilizers.
