3. Which among the following: Ferns, Mosses, Algae and Fungi, contain chlorophyll?
[A] Ferns and Algae
[B] Mosses and Algae
[C] Algae, Ferns and Mosses
[D] None of the given options
Show Answer
Correct Answer: C [Algae, Ferns and Mosses]
Notes:
Chlorophyll, the photosynthetic pigment that gives plants their green color, is present in Algae, Ferns and Mosses, thus enabling them to convert sunlight to chemical energy through photosynthesis. Although fungi are a group of organisms often thought to be plants, they lack chlorophyll, and hence, they are non-photosynthetic, surviving instead on organic matter.

[A] Gerontechnology
[B] Biomechatronics
[C] Orthotics
[D] Bionics
Show Answer
Correct Answer: B [Biomechatronics]
Notes:
Biomechatronics is an applied interdisciplinary science that aims to integrate mechanical elements, electronics and parts of biological organisms. Biomechatronics includes the aspects of biology, mechanics, and electronics. It also encompasses the fields of robotics and neuroscience. The goal of this science is to make devices that interact with human muscle, skeleton, and nervous systems. The end result is that the devices will help with human motor control that was lost or impaired by trauma, disease or birth defects.
