Which of the following apply to gymnosperm seeds EXCEPT:. a) enveloped by sporophyte tissues upon maturation. b) contained in a tight arrangement of sporophylls around a central stalk, as seen in pine cones. c) partially sheltered by modified leaves called sporophylls fully enclosed in an ovary

Fully enclosed in an ovary

Explanation:

A gymnosperm is a group of a plant which can be distinguished from other groups of a plant is through the presence of seeds but they are not enclosed and are naked.

The seeds are considered naked as they are not fully enclosed in the ovary like in the angiosperms rather they are present as on modified leaves called sporophylls and the cones.

The seeds are sheltered by the sporophyll and when they mature are enclosed by the sporophytic tissues. Since they are not enclosed in the ovary, therefore, are considered the gymnosperms.

Thus, the selected option is correct.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
