Answer:
Due to its distance from the Sun, Saturn is a rather cold gas giant planet, with an average temperature of -178 °Celsius.
Explanation:
Answer:
Small nonpolar molecules, such as O2(oxygen) and CO2(carbon dioxide)
Explanation:
Oxygen and carbon dioxide are soluble in the lipid bilayer (mostly because oxygen and carbon dioxide are lipids) and therefore can readily cross cell membranes. Small uncharged polar molecules, such as H2O(water), also can diffuse through membranes but will have a hard time doing so, but larger uncharged polar molecules, such as glucose(carbohydrates), cannot.
Hope this helps! Brainliest?? Anyways have a great day my loves <3

The leaf as a photosynthetic organ includes the following cells which contains chloroplasts
--> the palisade mesophyll
--> the spongy mesophyll and
--> the stomatal guard cells
Although all the green parts of a plant can be involved in the photosynthetic activities (with the exception of the root hairs), the leafs are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the chloroplasts of these plant. Chloroplasts are structures that contains chlorophyll which traps in energy from the sunlight.
The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous chloroplasts and is the main site of photosynthesis in the leaf.
The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain chloroplasts.
The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains chloroplasts which contributes to the movement of stomata.
Therefore the three different cells of the leaf that contains chloroplasts are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.
