Flowers, Fruits, and Seed

Grain

________ is a one seeded- fruit where the seed coat and ovary are fused.

Endosperm

________- provide nourishment from plants and us (the main source of calories in grains)

ovary

The ________ becomes the fruit that holds the ovule which becomes the seed that holds the endosperm and the embryo.

Monocots

________: have floral parts in groups of 3.

Monoecious

________- plant has both sexes.

Pollination

________: pollen is transferred from the anther to the stigma.

Inflorescences

________ (clusters) are groups of flowers on the same plant.

Self pollination

________: (same plant) advantages if well adapted, we good.

Pollinators

________ (vectors) determine flower, smell, look, and arrangement.

Double Fertilization

________: (2 fusions) the endosperm (3n) forms when the 2 polar bodies and 1 sperm nuclei form (this occurs in the pollen tube (formed by vegetative)) and the zygote (2n) is formed when the egg and the other sperm fuse, this becomes the embryo.

Wind pollinators

________ are basic (no color or smell) with a wide umbrella arrangement.

Pollen grains

________ are formed in the pollen sacs and each grain has 2 sperm nuclei (vegetative and generative)

Dry fruits

________ are tough and woody or thing and papery.

Fleshy fruits

________ are soft and juicy.

Monocots

have floral parts in groups of 3

dicots

floral parts in groups of 4 or 5

Whorls

floral organs (sepals, petals, stamen, carpels)

Androecium (male)

Stamen (filament (stem), anther hold pollen chambers that hold the pollen)

Gynoecium (female)

carpel (stigma (top)) style (stem) ovary (swollen bulb), ovules (hold eggs))

Monoecious

plant has both sexes

Dioecious

one plant has the stamen, a different one has carpel

Self-pollination

(same plant) advantages if well adapted, we good

cross-pollination

leads to better variation and diversity

Double Fertilization

(2 fusions) the endosperm (3n) forms when the 2 polar bodies and 1 sperm nuclei form (this occurs in the pollen tube (formed by vegetative)) and the zygote (2n) is formed when the egg and the other sperm fuse, this becomes the embryo

embryo

radicle, plumule, and cotyledon

Endosperm

provide nourishment from plants and us (the main source of calories in grains)
