The Structures and Functions of the flowering plant

Question 1

Stamen

Answer 1

The male reproductive organs of the flowering plant, consisting of the filament and anther, responsible for the production of male gametes for fertilization.

Question 2

Anther

Answer 2

The part of the stamen where pollen is produced.

Question 3

Filament

Answer 3

Holds/supports the anther up to make pollination easier.

Question 4

Petal

Answer 4

Protects reproductive parts of the flower and attracts pollinators.

Question 5

Receptacle

Answer 5

Acts as an axis to the flowering parts of the plant and supports the flower to keep it upright for pollinators.

Question 6

Stigma

Answer 6

Where pollen germinates.

Question 7

Style

Answer 7

A tube connecting the stigma to the ovary. The style helps guide pollen to the ovary so that the ovules can become fertilized.

Question 8

Ovary

Answer 8

The reproductive organ of the plant, which contains ovules.

Question 9

Pollen

Answer 9

Contains the male gametes required for fertilization.

Question 10

Sepal

Answer 10

Protects the reproductive organs of the flowering plant.

Question 11

Carpel

Answer 11

The female reproductive parts of the plant consisting of: ovary, stigma, and style.

Question 12

Pistil

Answer 12

Consists of several carpels or it can consist of a single carpel.

Question 13

Ovules

Answer 13

Forms the seeds of flowering plants. The pollen nucleus fuses with egg cell nucleus (which is in the ovules) causing fertilization, forming a new cell - zygote, divides and develop into plant embryos.

Question 14

Leaves

Answer 14

Site of photosynthesis, produce food (glucose) for the plant.

Question 15

Stem

Answer 15

Carries water and nutrients to different parts of the plant.

Question 16

Roots

Answer 16

Take up water and nutrients from the soil and keep the plant upright in the soil.

Question 17

Pollen tube

Answer 17

Forms within the styles and transports male gametes (pollen grain) to the ovary of a flowering plant.
