Science 3.3.1

Question 1

A fully grown and fully developed organism.

Answer 1

adult

Question 2

The pollen-producing sac of a stamen.

Answer 2

anther

Question 3

A type of asexual reproduction in which cell division with mitosis causes new individuals to develop on a parent.

Answer 3

budding

Question 4

The female reproductive part of a flower.

Answer 4

carpel

Question 5

The reproductive organ of a conifer. Male cones produce pollen, and female cones produce seeds.

Answer 5

cone

Question 6

A type of sexual reproduction in which individual cells come together to exchange or transfer genetic material before cell division.

Answer 6

conjugation

Question 7

A multicellular organism in the very early stages of development.

Answer 7

embryo

Question 8

An organism that produces only eggs for sexual reproduction.

Answer 8

female

Question 9

The fusion of an egg and a sperm to form a zygote.

Answer 9

fertilization

Question 10

The developing offspring of a mammal between the embryo stage and birth.

Answer 10

fetus

Question 11

A type of asexual reproduction in which a cell splits into two identical cells.

Answer 11

fission

Question 12

The reproductive organ of a flowering plant.

Answer 12

flower

Question 13

A type of asexual reproduction in which new individuals develop from pieces of an individual that break off.

Answer 13

fragmentation

Question 14

A distinct, immature stage of an organism’s offspring.

Answer 14

larva

Question 15

An organism that produces only sperm for sexual reproduction.

Answer 15

male

Question 16

A reproductive organ that produces eggs. In flowers, the ovary is part of a carpel and is where eggs are produced in ovules and seeds develop.

Answer 16

ovary

Question 17

The part of a cone or a flower in which an egg forms through cell division with meiosis. Ovules develop into seeds.

Answer 17

ovule

Question 18

Reproduction from an egg without fertilization.

Answer 18

parthenogenesis

Question 19

A flattened organ formed within a uterus to supply nourishment to developing mammals.

Answer 19

placenta

Question 20

The powdery grains produced in the anthers of a flower. Pollen grains contain sperm formed by cell division with meiosis.

Answer 20

pollen

Question 21

A plant embryo and its supply of stored food along with a protective coat.

Answer 21

seed

Question 22

A reproductive cell that can develop into a new organism by itself,without combining with another reproductive cell.

Answer 22

spore

Question 23

The male reproductive part of a flower.

Answer 23

stamen

Question 24

The sticky tip of a carpel of a flower. The stigma receives pollen grains.

Answer 24

stigma

Question 25

The stalk that leads from the stigma to the ovary of a carpel in a flower.

Answer 25

style

Question 26

A reproductive organ that produces sperm.

Answer 26

testis

Question 27

Thick-walled, female reproductive organs in which the offspring of vertebrates develop after fertilization.

Answer 27

uterus

Question 28

A type of asexual reproduction in which nonreproductive parts of an organism can break off and develop into new individuals.

Answer 28

vegetative reproduction
