Photosynthesis ceases when leaves wilt, mainly because stomata close, preventing CO2 from entering the leaf.
What is photosynthesis?Photosynthesis is a series of chemical reactions by which plants can produce simple carbohydrates in presence of light.
Photosynthesis requires carbon dioxide and light to produce glucose and release oxygen.
In plants, the interchange of carbon dioxide and oxygen during photosynthesis occurs in specialized structures called stomata.

Eukaryotic
Somatic
Plant
Answer:
Prokaryotic cells
Explanation:
Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm.
Answer:
a) Prokaryotic
Explanation:
Prokaryotic cells do not have any membrane-bound organelles. Hence, option (a) is the correct answer.
Plants, or autotrophs, do which of the following processes? (Select all.)
Glycolysis
Photosynthesis
Cell Respiration
None of the above
Answer:
Glycolysis, photosynthesis, and cellular respiration
Explanation:
Glycolysis takes place in the cytoplasm of animal and plant cells, whereas the subsequent steps of cellular respiration take place in the mitochondria.Plants have mitochondria and can perform cellular respiration. When would plants need to release energy by cellular respiration? Plants would release energy through cellular respiration in times when sunlight is not present.Multiple meanings the word matrix can be used to describe things shaped in a pattern of lines and spaces. How does this relate to a mitochondrion?
The mitochondrial matrix is the fluid inside the mitochondria. It is required during cellular respiration.
What are mitochondria?Mitochondria are eukaryotic organelles that can be considered the energy factories of this type of cell.
Mitochondria are able to synthesize ATP (the energy coin of the cell) by a process called cellular respiration.
The mitochondrial matrix is a fluid inside the mitochondria which is required to create a proton gradient during cellular respiration.

The term matrix in relation to a mitochondrion states that a fluid or jelly-like substance which is present inside the mitochondria and plays a vital role during cellular respiration.
What do you mean by Mitochondria?Mitochondria may be defined as a double membrane-bound cell organelle that is known as the powerhouse of the cell. This is because the energy required for various activities is released by mitochondria in the form of ATP.
The matrix of the mitochondria consists of small-sized ribosomes and DNA, which possess genetic information.
The mitochondrial matrix is the site of metabolic activities like the TCA cycle which is responsible for the conversion of pyruvate and fatty acids to acetyl-CoA.
Therefore, the term matrix in relation to a mitochondrion states that a fluid or jelly-like substance which is present inside the mitochondria and plays a vital role during cellular respiration.

10.A 600 kg great white shark is lurking below an observation cage. His movement is
being studied from a series of motion sensors below the boat. The shark leisurely
charges the cage, strikes it and makes the cage rattle. Later, the shark returns for
another run at the cage. The shark strikes the cage with 12,800 N of force. The
shark traveled for 10 m in making its run. The cage is designed to withstand
124,500 J of "work" before it breaks. Should the man in the cage be worried?
Explain.
The work done by the shark is 128000 J which is greater than the maximum force the cage can withstand (124500 J), the man in the cage should be worried.
What is work done?Work done is the product of force and the distance covered by the force.
Mathematically;
Work done = Force × distanceThe unit of work done is Joules.
The work done by the shark is calculated as follows:
Work done = 12800 × 10
Work done = 128000 J
Maximum force the can withstand = 124500 J
Since the work done by the shark is greater than the maximum force the cage can withstand, the man in th cage should be worried.

33. Why is it beneficial that plants have two kinds of chlorophyll (a and b)?
Answer:
chlorophyll in plants complement each other in absorbing sunlight.
Explanation:
light with a wavelength of 460 nm isn't always substantially absorbed by means of chlorophyll a, but will as a substitute be captured through chlorophyll b, which absorbs strongly at that wavelength. the two forms of chlorophyll in flowers
It is beneficial to have two kinds of chlorophyll in photosynthetic plants because both types of chlorophyll work complementary to each other and allow maximum absorption of light in the blue to red spectrum.
What do you mean by Chlorophyll?Chlorophyll may be defined as the green-colored pigment in plants, algae, and cyanobacteria that is essential for photosynthesis.
Chlorophyll A absorbs the light of wavelength 400 to 450nm with maximum intensity and 650 to 700nm with minimum intensity.
Chlorophyll B absorbs the light of wavelength 450 to 500nm with maximum intensity and 600 to 650nm with minimum intensity.
Therefore, it is beneficial to have two kinds of chlorophyll in photosynthetic plants because both types of chlorophyll work complementary to each other and allow maximum absorption of light in the blue to red spectrum.

a.
It occurs at the fastest rate.
b.
It is not essential to life.
c.
It does not occur naturally.
d.
It does not involve the atmosphere.
Answer:
The cycle only involves the lithosphere, hydrosphere, and biosphere, with no role in the atmosphere. The reason the atmosphere is not involved in that at the natural temperature and pressure of the environment, phosphorus and its compounds are usually in solid or ionic (usually phosphate ion) form. It is also a very slow nutrient cycle, with a major source of the nutrient being determined by tectonic activity that upwells the nutrients from deep in their earth’s core through volcanic activity.
