Answer 1

Answer:

1) the fluid matrix of the blood is called plasma . it is a straw coloured viscous liquid which contains the protein and other compounds

2) In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.

3)Ion release from guard cells causes stomatal pore closing: Other ion channels have been identified that mediate release of ions from guard cells, which results in osmotic water efflux from guard cells due to osmosis, shrinking of the guard cells, and closing of stomatal pores

4). At medium temperatures, between 50 and 68 degrees Fahrenheit, or 10 and 20 degrees Celsius, the photosynthetic enzymes work at their optimum levels, so photosynthesis rates gauge high.

5) Sensory neurons receive impulses and carry them from the sense organs to the spinal cord or brain. Interneurons connect sensory and motor neurons and interpret the impulse. Motor neurons carry impulses from the brain and spinal cord to muscles or glands.

6) most plant tissue are dead on maturity True

7) Stoma or stomata are small pores like opening at the lower surface of plants that helps in the exchanges of gases.

8) Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.

9) thylakoid membrane

The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the stroma

10) Adenosine triphosphate (ATP), a nucleotide composed of adenine, ribose, and three phosphate groups, is perhaps the most important of the so-called energy-rich compounds in a cell. Its concentration in the cell varies from 0.5 to 2.5 mg/mL of cell fluid.

11)Provides mechanical support to growing parts of plants such as young stem, petiole of leaf. (III) Sclerenchyma: It is a simple permanent dead mechanical tissue at maturity. - Consists of long, narrow cells with thick and lignified cell walls. - Provides mechanical support to the plant organs.

12) Bast fibre (also called phloem fibre or skin fibre) is plant fibre collected from the phloem (the "inner bark", sometimes called "skin") or bast surrounding the stem of certain dicotyledonous plants. It supports the conductive cells of the phloem and provides strength to the stem.

13) As stated above, breathing is the biological process of inhaling and exhaling of the gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs and nose. Respiration, on the other hand, is a chemical process that takes place in the cell.

14) The runner respires at higher rates than a person standing still; therefore, a runner's rate of respiration is higher and the temperature of the body increases. The same principle applies to plants, as temperature at night increases, the respiration rate increases and consequently temperature increases.

15)A urinary tract infection (UTI) is an infection in any part of your urinary system — your kidneys, ureters, bladder and urethra. Most infections involve the lower urinary tract — the bladder and the urethra. Women are at greater risk of developing a UTI than are men.

Answer 2

Answer:

1. False

Correct statement:

• Straw colored fluid matrix in the blood is called Plasma.

➛ Plasma is the straw-coloured fluid part of the blood whereas lymph is a colourless fluid.

2. False

Correct statement:

• During the process of photosynthesis, plants use energy from the sun

➛ Photosynthesis is the process by which the green plants use energy from the sun to convert carbon dioxide and water into sugars (glucose), in the presence of green coloured pigment called chlorophyll.

3. True

➛ When the guard cells lose water, they lose their turgidity and the stomata close, whereas when the guard cells are full of water, they swell and bulge outwards and the stomata open.

4. True

5. False

Correct statement:

• Sensory neurones carry impulses from the sense organ to the spinal cord.

➛ Sensory organs are the afferent neurons.

• They carry impulses from different parts of the body that is from sense organs to brain and spinal cord.

➛ Mixed neurones are connected neurones

• They are both afferent and efferent neurones. They carry the nerve impulse from sensory neurones to motor neurones.

6. True

7. False

Correct statement:

• Small pores on the lower surface of the leaves are called Stomata.

➛ The inner membrane of a chloroplast is folded into disc-shaped sacs called thylakoids.

8. False

Correct statement:

• During the process of photosynthesis plants use energy from the sun.

9. True

10. True

11. True

12. False

Correct statement:

• Phloem parenchyma are involved in the storage of reserve substances.

➛ Phloem fibres provide support.

13. False

• Respiration is not the same as breathing.

➛ Respiration is a biological process taking place inside the cell.

➛ Breathing is a chemical process of inhaling and exhaling air.

14. False

• Respiration occurs at a slow pace in plants.

➛ In animals, for respiration occurs at a very fast pace.

15. True

➛ A urinary tract infection (UTI) is an infection that occurs in the unitary system due to entrance of bacteria such as E. coli in urinary tract.
