The picture below represents which
stage of photosynthesis?
A. Dark reactions
B. Calvin Cycle
C Glycolysis
D Light reactions

It represents Glycolysis, a key metabolic route that produces energy and generates precursors for the production of primary metabolites in plants. Thus, option (C) is correct.

Green plants and certain other organisms convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.

The first method of breaking down glucose to release free energy is called glycolysis .Two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water are produced during glycolysis.


Hence, the picture depicts the process of gylcolysis , stage of photosynthesis i.e option (c)

Our atmosphere acts like a blanket trapping heat and keeping Earth at a habitable temperature, it’s this retaining of heat that is referred to as the Greenhouse Effect. The greenhouse effect is caused by greenhouse gases that trap heat from the sun, the more greenhouse gases there are the more heat is retained

HOW IT WORKS
The heat from the sun (solar radiation) has a very short wavelength and this can pass easily through the layer of greenhouse gases. This wavelength is called Ultraviolet radiation. As the UV rays strike the Earth, the Earth redirects the rays back into the atmosphere. We feel this as heat. The heat from the earth (terrestrial radiation) has a longer wavelength (infrared) some of this becomes trapped by the layer of greenhouse gases.

GREENHOUSE GASES
Water vapor (H20) is the most prevalent greenhouse gas and occurs naturally. Some greenhouse gases are both natural and man-made including carbon dioxide (CO2) & methane (CH4).

Describe the size of insolation when it strikes the Earth.

What would happen if there were no greenhouse gases to trap heat?

In the early days of life on Earth, plants were exposed to extremely high doses of ultraviolet radiation, Constant UV exposure
resulted in some land plants developing narrow leaves with thick, waxy cuticles. Over many, many generations, these narrow
leaves evolved into needles.
Relate the development of plant needles to the occurrence of mutations,
A)
Plant needles adaptations for survival that some plants developed due to
high temperatures on Earth
B)
Plant needles are the result of leaf cell mutations that made some leaves
thick and waxy, while other leaves did not change,
Plant needles are the result of neutral mutations to leaf tissue that would
neither help nor harm the plants living in such a harsh environment.
D)
Plant needles were a beneficial mutation that increased survival of certain
plants that reproduced and passed the mutated gene to offspring,

Which of the following can cause mutations?
A. All of the above

B. Radiation

C. Chemicals

D. Errors during DNA Replication
