Protists, Fungi, and Plants

Question 1

Protist

Answer 1

In some biological taxonomy schemes, protists were a large group of diverse eukaryotic, mainly unicellular microorganisms, that do not form tissues. Formerly, these were assigned to the now-obsolete kingdom Protista.

Question 2

Heterotroph

Answer 2

an organism deriving its nutritional requirements from complex organic substances.

Question 3

Eukaryote

Answer 3

A eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within membranes. Eukaryotes belong to the taxon Eukarya or Eukaryota.

Question 4

Decomposer

Answer 4

organisms that break down dead or decaying organisms, and in doing so they carry out the natural process of decomposition.

Question 5

Parasite

Answer 5

an organism that lives in or on another organism

Question 6

Host

Answer 6

person who receives or entertains other people as guests

Question 7

Fungi

Answer 7

fungus is any member of the group of eukaryotic organisms that includes unicellular microorganisms such as yeasts and molds, as well as multicellular fungi that produce familiar fruiting forms known as mushrooms.

Question 8

Spore

Answer 8

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.

Question 9

Lichen

Answer 9

A lichen is a composite organism that arises from algae or cyanobacteria (or both) living among filaments of a fungus in a symbiotic relationship.

Question 10

Giardia

Answer 10

Giardia is a genus of anaerobic flagellated protozoan parasites of the phylum Sarcomastigophora that colonise and reproduce in the small intestines of several vertebrates, causing giardiasis.

Question 11

Malaria

Answer 11

an intermittent and remittent fever caused by a protozoan parasite that invades the red blood cells.

Question 12

Toxoplasmosis

Answer 12

a disease caused by toxoplasmas, transmitted chiefly through undercooked meat, or in soil or cat feces.

Question 13

Asexual Reproduction

Answer 13

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 14

Cellular respiration

Answer 14

Cellular respiration is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.

Question 15

Photosynthesis

Answer 15

Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms’ activities.

Question 16

Gymnosperm

Answer 16

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

Question 17

Vascular plan

Answer 17

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

Question 18

Phototropism

Answer 18

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