Which cell structure allows a plant to carry out photosynthesis?

Plant cells contain cell structures like cell wall, plastids, and large vacuoles. Cell wall provide plant cells rigidity and structural support and cell to cell interaction. Plastids help in storage of plant products. Chloroplasts aid in carrying out the process of photosynthesis to produce food for the plants.

Explanation:

Chloroplasts allows plants to carry of photosynthesis.

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.

it doesn't. it was imagined up in the middle ages.
