Flashcards in Protist plant fungi Deck (23):
1

Protist

An organism that belongs to the kingdom of protista

2

heterotroph

an organism deriving its nutritional requirements from complex organic substances.

3

Eukaryote

an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria.

4

Decomposer

an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.

5

Parasite

an organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense.

6

Host

an animal or plant on or in which a parasite or commensal organism lives.

7

fungi

A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms.

8

spore

a minute, typically one-celled, reproductive unit capable of giving rise to a new individual without sexual fusion, characteristic of lower plants, fungi, and protozoans.

9

lichen

a simple slow-growing plant that typically forms a low crustlike, leaflike, or branching growth on rocks, walls, and trees.

10

nonvascular plant

Non-vascular plants are plants without a vascular system consisting of xylem and phloem.

11

vascular plant

a plant that is characterized by the presence of conducting tissue.

12

gymnosperm

a plant that has seeds unprotected by an ovary or fruit. Gymnosperms include the conifers, cycads, and ginkgo.

13

angiosperm

a plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, grasses, and most trees.

14

photosynthesis

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.

15

cellular resperation

a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate and then release waste products.

16

transpiration

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.

17

tropism

the turning of all or part of an organism in a particular direction in response to an external stimulus.

18

Gravitropism

a turning or growth movement by a plant or fungus in response to gravity

19

phototropism

the orientation of a plant or other organism in response to light, either toward the source of light

20

Asexual Reproduction

Asexual reproduction is a type of reproduction by which offspring arise from a single organism,

21

toxoplasmosis

a disease caused by toxoplasmas, transmitted chiefly through undercooked meat, or in soil or cat feces. Symptoms generally pass unremarked in adults, but infection can be dangerous to unborn children.

22

Malaria

an intermittent and remittent fever caused by a protozoan parasite that invades the red blood cells. The parasite is transmitted by mosquitoes in many tropical and subtropical regions.

23

Giardia

infection is an intestinal infection marked by abdominal cramps, bloating, nausea and bouts of watery diarrhea.
