Two the independent and dependent
For starters, plant cells have a tough Cell Wall made from cellulose, while animal cells only have the thin Cell Membrane. Also, plant cells have Plastids, while animal cells do not.
The primary organelle which is present in plant cells but not in animal cells, however, are the Chloroplasts, which allow plant cells to carry on the natural process of photosynthesis, by which plants make their own food using sunlight, water, and nutrients from the soil.
Hope that helped =)

The plant hormone auxin is the driving force behind the
plant's growth towards the sunlight to be able to generate energy by
photosynthesis. Highly sensitive light-sensing proteins help seedlings find the
shortest route (to sunlight) by elongating the cells of the stem on the side
that is farthest from the sunlight.
The roots are made up of cells that are dense with ball-like
structures called statoliths that respond to
gravity pulling it down. It enables the plant to grow perpendicular to
the sky.

Tropism is the plant's response to stimulus. When the plants
move toward the stimulus, it is called a
positive tropism. Negative tropism is the plants' movement away from the
stimulus. Both Phototropism and Geotropism are both tropisms.
Phototropism is the mechanism that enables the plant to respond
to light. Stems and leaves exhibit this process.
Geotropism or Gravitropism the mechanism that enables the
plant to respond to gravity. It allows the plant to orient themselves for
growth. Plant roots exhibit this process.
