Answer:
The correct answer is- facilitated diffusion
Explanation:
In facilitated diffusion molecules(solutes) are moved from area having a high concentration of solute towards the area having low solute concentration through a semipermeable membrane with the help of specific proteins is called facilitated diffusion.
As molecules move along the concentration gradients so no energy consumption is required in facilitated diffusion. Transport proteins like channel proteins are used to transport the molecules across the cell.
The rate of transport is higher in facilitated diffusion than simple diffusion. Polar and charged molecules can be diffused by facilitated diffusion.
Answer:
D. The substances utilized in response to light are produced in the terminal bud.
Explanation:
The substances which are produced in the apical meristem are known as the auxins. are responsible for solar tracking in plants. are a powerful growth hormone that are produced naturally by plants. They are mainly found in shoot and root tips and promote cell division, stem and root growth. They also drastically affect plant orientation by allowing cell division to one side of the plant in response to sunlight and gravity. That response to sunlight by the hormone is know as phototropism where the plant would move towards the source of light which promote its growth. The movement of auxins due to gravity it is known as geotropism where the hormones moves to one side of the root in response to gravity.
It weakens the infection. It also helps him not catch future infections and controls the spread of the infection.
