Protist, Fungi, Plants

Question 1

Protist

Answer 1

An organism that belongs to the kingdom Protista.

Question 2

Heterotroph

Answer 2

An organism that gets food by eating other organisms or their byproducts and that cannot make organic compounds from inorganic materials.

Question 3

Parasite

Answer 3

An organism that feeds on an organism of another species and that usually harms the host; the host never benefits from the presence of the parasite.

Question 4

Host

Answer 4

An organism from which a parasite takes food or shelter

Question 5

Decomposer

Answer 5

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

Question 6

Eukaryote

Answer 6

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.

Question 7

Fungi

Answer 7

any of a group of spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools.

Question 8

Spore

Answer 8

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

Question 9

Lichen

Answer 9

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

Question 10

Nonvascular Plant

Answer 10

These plants have no vascular tissue, so the plants cannot retain water or deliver it to other parts of the plant body.

Question 11

Vascular Plant

Answer 11

a plant that is characterized by the presence of conducting tissue

Question 12

Gymnosperm

Answer 12

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

Question 13

Angiosperm

Answer 13

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.

Question 14

Photosynthesis

Answer 14

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Question 15

Cellular Respiration

Answer 15

Cellular respiration is 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.

Question 16

Transpiration

Answer 16

the exhalation of water vapor through the stomata.

Question 17

Tropism

Answer 17

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

Question 18

Gravitropism

Answer 18

Gravitropism is a coordinated process of differential growth by a plant or fungus in response to gravity pulling on it.

Question 19

Phototropism

Answer 19

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

Question 20

Asexual Reproduction

Answer 20

Asexual reproduction is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes, and almost never changes the number of chromosomes.

Question 21

Toxoplasmosis

Answer 21

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.

Question 22

Malaria

Answer 22

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.

Question 23

Giardia

Answer 23

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