Explanation:
Vascular plants that have seeds surrounded by fruit are called as Angiosperms.
<h3>
Explanation:</h3>
Plants that have specialized vascular tissues that carry materials from one part of the plant to another is a vascular plant. The two types of vascular tissue, xylem and phloem, help in transportation of water, minerals, and the products of photosynthesis throughout the plant. Two types of vascular plants that produce seeds are : Gymnosperms and Angiosperms.
Gymnosperms are plants whose seeds are not enclosed by a fruit. The seeds are unenclosed or present on the surface or leaves. These seed are configured as cones. E.g: Cedar, pine
Angiosperms are fruit-bearing flowering plants with their seeds enclosed inside a fruit or flower. E.g: Apple, Eggplant
The answer is B) These illustrations show the progressive development of the forelimb in a species over time. One example of how life has changed over time.
Answer:
Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.
