What are the functions of leaves? (Select all that apply.) PLEASE ANSWER ASAP AND GET 25 POINTS
Fantom [35]

The main function of a leaf is to produce food for the plant by photosynthesis. Chlorophyll, the substance that gives plants their characteristic green colour, absorbs light energy. The internal structure of the leaf is protected by the leaf epidermis, which is continuous with the stem epidermis.

Conifer Leaf.  

Microphyll Leaf.  

Megaphyll Leaf.

A leaf is an above-ground plant organ and it is green. Its main functions are photosynthesis and gas exchange. A leaf is often flat, so it absorbs the most light, and thin, so that the sunlight can get to the chloroplasts in the cells. Most leaves have stomata, which open and close.

The two main functions performed by the leaf are photosynthesis and transpiration. Photosynthesis is the process by which green plants make their food from carbon dioxide and water in the presence of sunlight.

What would happen of the cell membrane were not selectively permeable
grandymaker [24]
If the cell membrane were not selectively permeable, then unwanted substances would transfer through instead of being blocked out. Think of it like this: you have a sifter with various sizes of spice in it. You only want the finer grains of spice in your food, so when you shake the sifter, the larger pieces of spice don't fit through the small holes that only allow fine grains. Then you are left with the small spices in your food and the large ones stuck in the sifter.
Hopefully this helps and I wasn't too confusing :)

Describe four ways a city can reduce car use.
Goryan [66]

Answer:

The city can build more convenient public transportation like trains and buses to transport people around in large numbers, reducing the amount of cars.

Likewise, the city can also find alternative options of energy sources to more renewable ones, like investing in a hydroplant and solar panels.

The city can also put up conveniently located bicycle stops with bicycles up for rent at an affordable cost, that will encourage more people to take other modes of transportation, while exercising as well.

Lastly, the city can also put up car taxes, to further reduce the numbers of cars on the road as not many people will be willing to pay the car taxes.
