How are plant and animal cells different?

Presence of chloroplast in plant cells

Explanation:

Chloroplast is an organelle found in the cytoplasm of plant cells, and helps in photosynthesis, by providing a site for trapping sun light which is used to produce food. Hence, plants are producers due to the presence of chloroplast while animals lack chloroplasts, so unable to produce their own food.

Thus, the presence of chloroplast in plant cells make it different from animal cells

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
