Question 1

The uptake of small nutrient molecules by an organism’s own body; the third main stage of food processing, following digestion.

Answer 1

Absorption

Question 2

A life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte; a characteristic of plants and multicellular green algae.

Answer 2

Alternation of generations

Question 3

A flowering plant, which forms seeds inside a protective chamber called an ovary

Answer 3

Angiosperm

Question 4

A sac in which pollen grains develop, located at the tip of a flower’s stamen.

Answer 4

Anther

Question 5

A structure at the tip of a plant root or in the terminal or axillary bud of a shoot.

Answer 5

Apical meristem

Question 6

One of a group of plants that lack xylem and phloem; a nonvascular plant. Examples of
this type of plant include mosses, liverworts, and hornworts.

Answer 6

Bryophyte

Question 7

The female part of a flower, consisting of a stalk with an ovary at the base and a stigma, which traps pollen, at the tip

Answer 7

Carpel

Question 8

Member of a group of fungi that are mostly aquatic and have flagellated spores. They probably represent the most primitive lineage of this group.

Answer 8

Chytrid

Question 9

Member of a group Basidiomycete and characterized by club-shaped, spore- producing structures called basidia.

Answer 9

Club Fungus

Question 10

Another name for land plants, recognizing that land plants share the common derived traits of multicellular, diploid, eukaryote.

Answer 10

Embryophyte

Question 11

An energy-containing deposit of organic material formed from the remains of ancient organisms.

Answer 11

Fossil Fuel

Question 12

A ripened, thickened ovary of a flower, which protects developing seeds and aids in their dispersal.

Answer 12

Fruit

Question 13

A heterotrophic eukaryote that digests its food externally and absorbs the resulting small nutrient molecules. This group consists of a netlike mass of filaments called hyphae. Molds, mushrooms, and yeasts are examples of this group.

Answer 13

Fungus

Question 14

A reproductive organ that houses and protects the gametes of a plant.

Answer 14

Gametangium

Question 15

The multicellular haploid form in the life cycle of organisms undergoing alternation of generations; mitotically produces haploid sperm or eggs that unite and grow into the sporophyte generation.

Answer 15

Gametophyte

Question 16

Member of a group of fungi characterized by a distinct branching form of mycorrhizae (symbiotic relationships with plant roots) called arbuscules.

Answer 16

Glomeromycete

Question 17

A naked-seed plant. Its seed is said to be naked because it is not enclosed in an ovary.

Answer 17

Gymnosperm

Question 18

A fungal life cycle stage that contains two genetically different nuclei in the same cell.

Answer 18

Heterokaryotic

Question 19

One of many filaments making up the body of a fungus.

Answer 19

Hypha

Question 20

This eukaryotic organism has no known sexual stage.

Answer 20

Imperfect fungus

Question 21

A close association between a fungus and an alga or between a fungus and a cyanobacterium, some of which are known to be beneficial to both partners.

Answer 21

Lichen

Question 22

A chemical that hardens the cell walls of plants.

Answer 22

Lignin

Question 23

A rapidly growing fungus that reproduces asexually by producing spores zygosporangium
during sexual reproduction.

Answer 23

Mold
