Which of the following statements correctly compares the functions of a plant's roots and stem?

The stem contains a high percentage of cells that provide structural support, unlike the roots.

The stem is the first part of the plant to emerge from a seed, followed by the roots.

The roots contain ground tissue that stores water and glucose, unlike the stem.

The roots contain stomata that allow for gas exchange, while stems do not.

Your answer would be the first one.

It's not the 3rd option, because the stem stores water

Roots do not contatin stomata

I beleive it would be either of the first two; my guess would be the 2nd

the second one

To determine which statement correctly compares the functions of a plant's roots and stem, let's analyze each statement one by one:

Statement 1: "The stem contains a high percentage of cells that provide structural support, unlike the roots."
This statement is not entirely accurate. While it is true that the stem does contain cells that provide structural support, the roots also play a crucial role in supporting the plant by anchoring it in the ground and absorbing nutrients from the soil.

Statement 2: "The stem is the first part of the plant to emerge from a seed, followed by the roots."
This statement is correct. During embryonic development in plants, the stem is the first part to emerge from a seed, followed by the roots. This is because the stem serves as the plant's axis of growth that upwardly extends towards sunlight, while roots grow downwards into the soil.

Statement 3: "The roots contain ground tissue that stores water and glucose, unlike the stem."
This statement is not accurate. Both the roots and stem contain ground tissue that stores water and glucose. In the stem, this tissue is mainly found in the pith and cortex, while in roots, it is primarily present in the cortex.

Statement 4: "The roots contain stomata that allow for gas exchange, while stems do not."
This statement is also not accurate. Stomata, which are tiny openings in the plant's epidermis, are primarily present in the leaves and stems. Stomata allow for gas exchange, including the intake of carbon dioxide and the release of oxygen during photosynthesis.

Considering this analysis, the correct statement that compares the functions of a plant's roots and stem is Statement 2: "The stem is the first part of the plant to emerge from a seed, followed by the roots."
