SCIENCE QUESTION Chloroplasts are organelles found only in plant cells. Why are chloroplasts not needed in animal cells?

Animals have bones for support and don't need rigid chloroplasts to provide structure.

Animal cells have ribosomes for protein synthesis, unlike plants which use chloroplasts.

Animals obtain energy from eating other things, not from photosynthesis.

What came first egg or chicken? and is tomato a vegetable or a fruit?

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
