Question 3

In animals, the female gonad, which produces egg cells and reproductive hormones. (2) In flowering plants, the basal portion of a carpel in which the egg-containing ovules develop

Answer 3

Ovary

Question 4

Organism that derives its nutrition from a living host, which is harmed by the interaction

Answer 4

Parasite

Question 5

A modified leaf of a flowering plant. These structures are often the colorful parts of a flower that advertise it to pollinators

Answer 5

Petal

Question 6

The portion of a plant’s vascular tissue system that conveys phloem sap throughout a plant. This tissue is made up of sieve-tube members.

Answer 6

Phloem

Question 7

The structure that will produce the sperm in seed plants; the male gametophyte.

Answer 7

Pollen Grains

Question 8

In seed plants, the delivery of pollen, by wind or animals, from the male parts of a plant to the stigma of a carpel on the female.

Answer 8

Pollination

Question 9

Member of a Ascomycete characterized by saclike structures called asci that produce spores in sexual reproduction.

Answer 9

Sac Fungus

Question 10

A plant embryo packaged with a food supply within a protective covering

Answer 10

Seed

Question 11

A tough outer covering of a seed, formed from the outer section (integuments) of an ovule. In a flowering plant, this structure encloses and protects the embryo and endosperm

Answer 11

Seed Coat

Question 12

The informal collective name for lycophytes (club mosses and their relatives) and pterophytes (ferns and their relatives).

Answer 12

Seedless Vascular Plants

Question 13

A modified leaf of a flowering plant. A whorl of these encloses and protects the flower bud before it opens

Answer 13

Sepal

Question 14

A structure in fungi and plants in which meiosis occurs and haploid spores develop.

Answer 14

Sporangium

Question 15

(1) In plants and algae, a haploid cell that can develop into a multicellular individual without fusing with another cell. (2) In prokaryotes, protists, and fungi, any of a variety of thick-walled life cycle stages capable of surviving unfavorable environmental conditions

Answer 15

Spore

Question 16

The multicellular diploid form in the life cycle of organisms undergoing alternation of generations; results from a union of gametes and meiotically produces haploid spores that grow into the gametophyte generation.

Answer 16

Sporophyte

Question 17

A pollen-producing male reproductive part of a flower, consisting of a filament and an anther.

Answer 17

Stamen

Question 18

A plant with xylem and phloem, including club mosses, ferns, gymnosperms, and angiosperms, vascular tissue Plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body.

Answer 18

Vascular Plant

Question 19

A system formed by xylem and phloem throughout the plant, serving as a transport system for water and nutrients, respectively

Answer 19

Vascular Tissue System

Question 20

The nonliving portion of a plant’s vascular system that provides support and conveys this substance (sap) from the roots to the rest of the plant. It is made up of vessel elements and/or tracheids, water-conducting cells

Answer 20

Xylem

Question 21

A single-celled fungus that inhabits liquid or moist habitats and reproduces asexually by simple cell division or by the pinching of small buds off a parent cell.

Answer 21

Yeast

Question 22

Member of a group of fungi characterized by a sturdy structure called a zygosporangium during sexual reproduction

Answer 22

Zygomycete
