Which substances does the stem help in transporting? Name the starting points and destination.

$\small\underbrace \mathfrak \pink{❥︎ANSWER }$

A stem helps in the transportation of food, water and minerals to every part of the plant. The starting point for the absorption of minerals and water is the roots and these are destined for buds, fruits, flowers, fruits and leaves.

Other than the main functions that almost all stems perform, there are other specialised function by formed by sterns of some plants. Name two such plants and the specialised 3.

$\small\underbrace \mathfrak \pink{❥︎ANSWER }$

Stems have cells called meristems that annually generate new living tissue. Stems have two pipe-like tissues called xylem and phloem. The xylem tissue transports water by the action of transpiration pull, capillary action and root pressure. The phloem tissue consists of sieve tubes and their companion cells.

During photosynthesis, leaves convert water and carbon dioxide to a kind of sugar called glouse.If that is so, all food stored by the plant should be sweet. But this is not so. Why?

$\small\underbrace \mathfrak \pink{❥︎ANSWER }$

Sugar stored by plants is glucose which is not a very sweet sugar like fructose or sucrose.

A plant is found to have fibrous roots. Can you say what kind of venation its leaves have?

$\small\underbrace \mathfrak \pink{❥︎ANSWER }$

Plants with fibrous roots have parallel venation in their leaves.
