Pre-Lab SEEDLESS Plants Lab 5

These flashcards cover key concepts discussed in the lecture on plants, focusing on plant life cycles, major plant groups, and characteristics of seed plants.

Alternation of Generation

A life cycle in plants consisting of alternating stages—haploid (n) gametophyte and diploid (2n) sporophyte.

Three Major Groups of Modern Plants

Bryophytes, Angiosperms, and Gymnosperms.

Common Ancestor of Modern Plant Groups

Green algae are considered the common ancestor to the three major groups of modern plants.

First Plants to Colonize Terrestrial Environment

Mosses (or bryophytes) were the first plants to colonize land.

Derived Character of Ferns

The development of vascular tissue, which allows ferns to grow taller.

Seed

A reproductive unit of a plant, consisting of an embryo and a food supply enclosed in a seed coat.

Two Major Groups of Seed Producing Plants

Angiosperms and Gymnosperms.

Differentiation of Seed Producing Groups

Angiosperms produce seeds enclosed in a fruit, while Gymnosperms produce naked seeds, typically in cones.
