Leaf cells can absorb nutrients from the air, but root cells require soil to absorb nutrients.

Leaf cells can reproduce, but root cells cannot.
Leaf cells and root cells have different functions and structures, resulting in several differences between them.
1. Leaf cells have nuclei, while root cells do not. Both types of cells contain genetic material in their nuclei, but leaf cells have visible nuclei, while root cells have a higher concentration of cytoplasm and a lower nucleus-to-cytoplasm ratio, making their nuclei less visible.
2. Leaf cells have chloroplasts, while root cells do not. Chloroplasts are organelles responsible for photosynthesis, which occurs in leaf cells. Root cells do not carry out photosynthesis and thus do not require chloroplasts.
3. Leaf cells can absorb nutrients from the air through structures called stomata, while root cells require soil to absorb nutrients. Leaf cells have specialized structures called stomata that allow the exchange of gases, including the uptake of carbon dioxide for photosynthesis. In contrast, root cells have root hairs and other adaptations to efficiently absorb water and nutrients from the soil.
4. Leaf cells can reproduce, while root cells cannot. Leaf cells can undergo mitosis, the process of cell division, allowing them to reproduce and replace damaged or aged cells. Root cells, on the other hand, do not undergo mitosis and primarily function in absorption and anchoring the plant.
answer my question
I apologize for any confusion. No, leaf cells and root cells both have nuclei.
thank you
You're welcome! If you have any more questions, feel free to ask.
Of the five characteristics of living things, which one is required for the species to survive but does not have to apply to an individual?

The characteristic that is required for the species to survive but does not have to apply to an individual is reproduction. While individuals within a species may or may not reproduce, it is necessary for the species as a whole to reproduce in order to continue its existence.
answer my question
The characteristic that is required for the species to survive but does not have to apply to an individual is reproduction. While reproduction is crucial for the survival and continuation of a species, not every individual within the species needs to reproduce for the species to persist.
A student claims that, according to cell theory, the cell is the basic unit of life, and all cells are created spontaneously. Is this student correct?
Responses
Yes, the student is correct because the basic unit of life is the cell.
Yes, the student is correct because the basic unit of life is the cell.
Yes, the student is correct because all cells are created spontaneously.
Yes, the student is correct because all cells are created spontaneously.
No, the student is not correct because the basic unit of life is within a cell.
No, the student is not correct because the basic unit of life is within a cell.
No, the student is not correct because all cells come from preexisting cells.
