transport
The movement of a chemical substance through a gradient of concentration or
electrical potential in the direction opposite to normal diffusion, requiring
the expenditure of energy

protist
The protists transport materials by first
digesting the material internally and transport through the use of hair like
cilia which surround their bodies. Protists are eukaryotic microorganisms from
the kingdom protista. They live in any environment that contains liquid
water.

annelid worms
Annelid worms transport blood through ring
vessels. They have a closed circulatory system, unlike other
worms.

insects
Insects use a crude, muscular pump to circulate a
bloodlike fluid freely throughout their body, in contrast to the closed
circulatory systems of vertebrates that contain blood within a network of
vessels. Insects' circulatory fluid is termed" hemolymph

nonvascular plants
rely on passive osmosis to reach internal cells.
While the outer cells absorb water inner cells must wait til water passively
moves through cell walls. That is the environment controls the mosses’ state of
hydration they cannot control it internally. This limits how many cells thick
the mosses can grow. They are limited to the distance water can move
osmotically, in sufficient quantities, to support life in the inner cells.

Plants may not have blood vessels and a heart, but they
nevertheless have transport systems of cells which form tubular vessels to
transport molecules and ions in solution from one place to another. The xylem
tissue carries water and dissolved ions from the roots to the aerial parts of
the plant.
