Spores

The sporophyte generation is diploid (2n)/haploid(n) and produces spores by_____ .

Diploid (2n); meiosis

The gametophyte generation is diploid (2n)/haploid(n) and produces gametes by _____.

Haploid (n); mitosis

In alternation of generations, the fusion of two gametes (sperm and egg) forms a ____.

Diploid zygote

The _____ develops into the sporophyte generation through mitotic divisions.

Zygote

______ are single-celled reproductive structures that develop into the gametophyte generation.

Haploid spores

____ is a type of green alga closely related to land plants and has complex reproductive structures called gametangia.

Chara

_____ is a filamentous green alga that reproduces sexually through conjugation, without specialized gametangia.

Spirogyra

Vascular plants possess specialized tissues for water and nutrient transport, namely ___ and ____.

Xylem; phloem

Non-vascular plants (like mosses) typically absorb water and nutrients directly from their surroundings through____ and _____.

Diffusion; osmosis

Vascular plants are characterized by having true ___,____ , and___ .

Roots; stems; leaves

In non-vascular plants, the_____ is the dominant and most conspicuous stage of the life cycle.

Gametophyte

What is the primary function of xylem?

To transport water and dissolved minerals from the roots upwards to all other parts of the plant.

What is the primary function of phloem?

To transport sugars (produced during photosynthesis) from the leaves to other parts of the plant where they are needed for growth or storage.
