Which organelles are involved in energy conversion? (1 point)
a. mitochondria and chloroplasts
b. mitochondria and ribosomes
c. smooth and rough endoplasmic reticulum
d. golgi apparatus and chloroplasts 3.)which means of particle transport requires input of energy from the cell? (1 point)
a. diffusion
b. osmosis
c. active transport

Organelles involved in energy conversion are A. MITOCHONDRIA AND CHLOROPLASTS

* ribosomes - protein builder
* SER - production and metabolism of fats and steroid hormones
* golgi apparatus - process and package macromolecules (proteins and lipids)

D. ACTIVE TRANSPORT is a means of particle transport that requires input of energy from the cell.

*In diffusion, particles tend to move from an area where they are more concentrated to an area of lesser concetration.
*facilitated diffusion does not require additional energy.
Osmosis is an example of facilitated diffusion.

No because the eaeht is on a 23.5 degree axis tilt and so when it is winter the northern hemisphere is pointing away from the sun and the soutubern hemisphere is pointing toward the sun
