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.
Answer:
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by-products and ATP is energy that is transformed from the process.
