a) Name the structures that: i) Carry water and mineral salts to the leaf ii) Prevents too much water loss from the upper surfac
e of the leaf iii) Opens to allow gases to pass into and out of the leaf iv) Is the site for most of the photosynthesis taking place v) Is the layer where light is able to pass through directly b) How does a leaf protect itself from unwanted intruders like bacteria from getting in and stopping important reactants from going out? PLEASE ANSWERR
The plant's leaves have a large surface area that is capable of absorbing sunlight. The plant's waxy layer in the surface of the leaf protects it from the loss of water, as well as of diseases caused by the entry of microorganisms. The palisade cell's surface is a single layer of cells underneath the upper epidermis that is adapted to absorb light energy.
The waxy layer is a primary physical barrier composed of insoluble polymers and lipids whose function is to protect the leaves against the entry of harmful organisms including virus, bacteria and fungus. Moreover, the plant's waxy cuticle is also a barrier that prevents the loss of water and solutes.
Scientific investigations that involve some kind of testing will make use of observations. generally speaking making observations is the first step of the scientific method.
Wind blows air on the surface of the earth from a high pressure center to a low pressure center (this is depicted in the image attached). The area between the two "centers" is referred to as pressure gradient. The warm air in the region of the low pressure center then rises up into the atmosphere. The warm air then cools up in the atmosphere and then passed down back to the earth's surface
