<h2>answer:</h2>

Active transport is the movement of molecules from a region of their lower concentration to a region of their higher concentration

<h2>explanation:</h2>

Active transport is the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentration—in the way opposite to some gradient or other obstructing factors (often an intensity gradient).

While active transport, particles travel against the concentration gradient - and hence need an input of energy from the cell.

Arrange the following in the correct sequence, from earliest to most recent, in which these plant traits originated. 1. sporophy
zavuch27 [327]

Answer:

Earliest- gametophyte dominance, sporophyte dependence

Middle- sporophyte dominance, gametophyte independence

Recent-  sporophyte dominance, gametophyte dependence

Explanation:

The life cycle of plant alternates between the two phases: the haploid gametophyte which produces gametes and the diploid sporophyte which produces spores.  The evolution of land plants shows how these are dependent on each other in terms of the requirement of nutrition.

In bryophytes, the gametophyte is the dominant phase on which the sporophyte depended. Later in pteridophytes, the sporophyte became dominant which is present in the later evolved groups namely the gymnosperms and the angiosperms. The gametophyte was independent on the sporophyte but in angiosperms and gymnosperms, it is dependent.
