How does the plant get all of the reactants needed for photosynthesis?

Biology
1 answer:
Inga [223]3 years ago
6 0
The reactants of photosynthesis are CO2 or Carbon Dioxide and H2O or Water.

Water is gains from the air or from the ground or from droplets on leaves from rain. If from the ground then the plants roots suck up the water and it travels up the plant via the capillary action to the leaves where the chloroplasts are. Other wise water enters via osmosis.

CO2 enters the plant via simple diffusion into the cells of the plant leaves and eventually into the chloroplasts.

5. The permease (transporter) allows glucose and Na into the cell requires ATP. True or False?
dem82 [27]

Answer: 5. False 6. False

Explanation: The permeases are membrane transport proteins, they're secondary active transporter that allow the movement of a specific molecule in or out of the cell in the direction of a concentration gradient, it is a form of facilitated diffusion and does not require energy. The permease secondary transporter uses the Na ion concentration to move glucose into the cell.

When the ion concentration gradient is set, the concentration of glucose in the cell is higher than the concentration of blood. Glucose will move to the blood by passive diffusion through permease secondary transporter.

The transport mechanism is carrier mediated it does not require energy.

humans developed antibiotics to fight bacterial infections however some antibiotics are no longer effective in killing the bacte
Lapatulllka [165]

Answer:

Changes in genetic makeup occurs with the passage of time.

Explanation:

Antibiotic cause mutation in the bacteria which allowed to develop resistance in the bacteria. This resistance and change in the genetic makeup obeys the theory of evolution which states that all species are changed gradually with the passage of time. The genetic makeup of bacteria also changes with the passage of time and attain resistance due to regular application of antibiotics so due to this resistance, the antibiotic can't work on the bacteria.

The frequency of autosomal alleles K and k in a large population of snails is 0.6 and 0.4. What is the approximate genotypic fre
Flura [38]

Answer:

Option (b).

Explanation:

The frequency of alleles K and k in population are 0.6 and 0.4. The inbreeding coefficient is 0.3.

The heterozygote frequency can be calculated by the formula:

F = \frac{2Kk-H}{2Kk}

Here, K = 0.6, k= 0.4, F = 0.3 and H = approximate genotypic frequency of heterozygote Kk.

Put the values in the above formula

0.3 = \frac{2\times2\times0.6\times0.4-H}{2\times0.6\times0.4}

H = 0.36 ≈ 0.34.

Thus, the approximate genotypic frequency of the heterozygote Kk is 0.34.

Hence, the correct answer is option (b).
