Which of the following statement is wrong? A)Leaves can make food when there is sunlight

B)Stamen will develop into a fruit

C)Stem helps in the conduction of water

D)Plants need air, water and sunlight to grow

C) Stem helps in the conduction of water

Explanation:

It's the xylem and phloem present in the vascular bundles of stems that conduct water and minerals across the plant. Stems bear flowers and fruits in a position that facilitates the processes of pollination, fertilization, and dispersion of seeds. So, stem doesn't help in the conduction of water.

the person above is correct

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

put the answers   and i could answer.
