modes of reproduction in flowering and non flowering plants

sexual reproduction

involves one female parent and one male parent for reproduction. plants that undergo ______ grow new plants through seeds.

asexual reproduction

plants reproduce wi/o the need of 2 parents, but through the parts of one plant

angiosperms

flowering pants are also called _________.

flower

the reproductive organ angiosperms use in sexual reproduction

angiosperms

have true stem that enables them to distribute water and nutrients throughout their different parts.

stamen

the male reproductive part of the flower.

filament

the long & slender part that holds the anther

anther

the head of the stamen produces pollen grains. the pollen grain contains the male sex cell, also known as the male gamete.

carpel

also known as pistil, is the female reproductive part of a flower.

stigma 

style

ovary

ovule

the carpel has many parts:

stigma

is @ the topmost area of the carpel. it has a sticky opening which receives pollen grains

style

long slender stalk that holds the stigma

ovary

the base of the carpel. it holds the ovules

ovule

contains the egg cells or the female gametes of a flower.

monoecious plants

bisexual flowers

dioecious plants

unisexual flowers

pollination

self-pollination

cross-pollination

sexual reproduction of flowering plants

pollination

when a pollen grain produced by the male part (stamen) reaches the stigma of the carpel (female part)

self-pollination

the pollen grain reaches the stigma of the same flower

cross-pollination

the pollen grains reach the stigma of another flower but of the same species.

pollination, fertilization, formation of fruits and seeds, seed dispersal, and germination

sexual production involves the union of the male and female sex cells. it consists of important processes:

asexual reproduction, natural vegetative propagation, artificial vegetative propagation.

__________ in plants does not involve the union of male and female sex cells and requires only one parent. it is also called vegetative propagation/cloning thus offspring are identical. this method of reproduction is of 2 kinds:____________

germination

the pollen that reaches the stigma germinates which means it develops into a pollen tube.

pollen tube

the pollen that reaches the stigma germinates which means it develops into a?

fertilization

one sperm cell will unite with an egg cell. this union becomes a zygote then turns into an embryo.

embryo

contians the earliest forms of the roots, stems, and leaves of a plant.

endosperm

serves as the food storage tissue of the baby plant as well as the outside coat forming the seed.
