The plant life cycle has mitosis occurring in spores, produced by meiosis, that germinate into the gametophyte phase. a. true b. false

The statement about the plant cycle is true.

All plants experience an actual existence burn that takes them through both haploid and diploid ages. The multicellular diploid structure of plant is known as the sporophyte that produces spores through meiotic (agamic) division. The multicellular haploid structure of plant is known as the gametophyte, which is shaped from spore and offer ascent to haploid gametes.  

The change between these haploid stage and diploid stage that happens in plants is known as the generations alternation. The manner by which the generations alternation happens in plants relies upon the kind of plant. In bryophytes (greeneries and liverworts), the predominant age is haploid, so the gametophyte includes what we consider as the primary plant.

The inverse is valid for tracheophytes (vascular plants), in which the diploid age is predominant and the sporophyte involves the primary plant.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
