Answer:
plant cells have chloroplasts and a cell wall. (they also have one large central vacuole.)
Explanation: Chloroplasts are found only in plant cells. Chloroplasts convert energy from the sun into sugar (glucose). The chloroplast is also where photosythesis happens in the plant cell. The cell wall is also only found in a plant cell. The cell wall protects and mantains the shape of the cell. And you don't have to put this one but the central vacuole is just one big vacuole in a plant cell that stores mainly water and nutrients since plant cells require more water to function, whereas in animal cells they have multiple small vacuoles.
A catalyst increase a chemical reaction, therefore making the answer B. Promotes a chemical reaction.

The correct answer is isobar.
The isobars refer to the lines of constant pressure. It is a line drawn on a map of a weather linking the points of equivalent pressure. The isobars are produced from mean sea level pressure reports and the values of pressure are illustrated in millibars.
The isobars help in demonstrating that how pressure are changing over space and so assist in illustrating the large-scale weather patterns across a region on the map.
D) It controls materials that enter and exit the cell
