BIO101 Unit 5

Kingdom Plantae I

angiosperms

flowering plants that produce seeds which are enclosed in fruits.

bryophytes

phylum of non-vascular plants which lack true roots, stems or leaves; moss, hornworts, and liverworts are examples of plants of this phylum.

conifers

cone-bearing gymnosperm plants that include pine, cedar, and spruce trees.

deciduous

a group of angiosperm woody trees that shed their broad leaves during the fall and grow new ones in the spring.

dicot

Abbreviation of dicotyledon. Flowering plant group; members have two embryonic leaves, net-veined leaves, and flower parts in 4’s and 5’s.

evergreen

a group of gymnosperms that have needle-like leaves and stay green during all seasons.

gametophyte

the haploid generation of alternation of generations life cycle of plants; produces the gametes that unite to form a diploid zygote which develops into the sporophyte generation.

gymnosperms

a type of woody seed plant where the seeds are produced “naked” in cones.

herbaceous

A plant with soft, green stems with little or no woody tissues; these plants usually die back each winter.

monocots

Abbreviation of monocotyledon. Flowering plant group; characteristically members have one embryonic leaf, parallel-veined leaves, and scattered vascular bundles.

multicellular

refers to an organism which is composed of many cells

phloem

vascular tissue that conducts food in plants.

photosynthesis

process by which plants and algae make their own food using the energy of the sun

protonema

structure which replaces the leaf in bryophytes.

rhizoids

rootlike underground structure of bryophytes

sporophytes

the diploid generation of the alternation of generations life cycle of plants; produces haploid spores that develop into the gametophyte generation.

vascular plant

a plant that has vascular tissue (xylem and phloem)

woody

Plants whose secondary xylem builds up year after year forming annual rings. These plants do not die back in the winter.

xylem

vascular tissue that transports water and minerals upward through the plant body.
