25
Q

A flower structure is specialized for _________ reproduction

A

Sexual

26
Q

Flowers with male and female parts on the same flower are called…

A

Perfect or Complete

27
Q

Flowers that only have male or female parts are called…

A

Imperfect or Incomplete

28
Q

Male reproductive organs:

A

Stamen is composed of anther and filament and makes pollen.

29
Q

Female reproductive organs:

A

The pistil is composed of the stigma, style, and ovary which makes ovules (eggs)

30
Q

Pollination -

A

When pollen goes from the anther to the stigma

31
Q

Self pollination -

A

The transfer of pollen to the anther to the stigma of the same plant or flower

32
Q

Cross pollination -

A

The transfer of pollen to the anther to the stigma of a different plant.

33
Q

Cross pollination can be completed by…

A

Bees, wind, and animals

34
Q

Som traits that help cross pollination are…

A

Scent, color, and shape

35
Q

What happens after the pollen lands on the stigma?

A
  1. The pollen germinates and forms a pollen tube which connects to the ovule
  2. The sperm nuclei are formed and fertilize the ovules
  3. The sperm and ovule conjoin to form zygote
  4. The zygote forms into an embryo which developed into a seed
  5. The ovary becomes the fruit

A

Growth and development

43
Q

Plant hormones are called…
