Bess [88]

Answer:

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.

I need any biology project ideas.
Studentka2010 [4]

Did a bit of research, found a cool one.

Did you know that our brains are split into two parts, right inside our head? One half is the left brain and the other half is the right brain. Some people use one half of the brain more than the other half when they are doing certain activities, like talking or reading. The half that is used is sometimes tied to which hand they prefer to use. If someone likes to use their right hand when doing an activity, like drawing or throwing a ball, do they also prefer to use their right ear, eye, or foot when hearing, seeing, or kicking something? Which side do people use the most? In this science project, you will get to find out!
