TERM 1
1. What are the features of angiosperm
reproduction?
DEFINITION 1
Male gametophate pollen in anthers of flower Female
gamytophyte develop in ovaries of flower -- ovary
wall become fruit
TERM 2
. Review basic flower anatomy (stamen:
anther, filament; carpel: stigma, style, ovary;
petals, sepals, receptacle) and the function of
each structure.
DEFINITION 2
mi Microsporangium = polle n sac v female gametophyte =
embryo sac carpel: female, stigm a: on the top the tube -- style
neck of the tube -- ovary: at the end of the tube receptacle is
under the ovaries staMen: male , ant her: has pollen filament: an
tube, which attached to the anther Sepal : -- petal: Pollen release
form ANTHER and land on STIGMA. P OLLEN GRAIN produce
POLLEN TUBE. Pollen tube grows d own STYLE into OVARY and
discharges 2 sperms into the EMBRY O SAC. 1 sperm fertilize egg
(zygote). OVULE develops into a se ed. Ovary developes into a
FRUIT.
TERM 3
3. Know the difference between complete and
incomplete flowers, as well as perfect and
imperfect flowers.
DEFINITION 3
Complete: contain all four floral organs Incomplete:
Lack of some organs, such as carpel and stamen
Perfect: has male and female part Imperfect:
TERM 4
4. What is the fate of the microspore? What
does the pollen grain do?
DEFINITION 4
Microspores produce pollen wi thin the pollen
sacs(microsporangia) of anth er Pollen grain= 2-celled male
gamytophyte+ the spore wall Pollen grain(male
gamytophyte) land on stigma 2 s perm without tails go
through pollen tube on e sperm fertilize egg make a zygote
other sperm fertilize the 2 pola r nuclei and form 3n
endosperm
TERM 5
What is the fate of the ovary and the ovules?
What makes a fruit a fruit rather than a
vegetable?
DEFINITION 5
Ovule: integuments+megasporangium Fruit is mature
ovary, wall of ovary thickens to form fruit, Fruit has
seed but vegetable doesnt

6. What are the major steps of seed

germination?

DEFINITION 6

Ovule seeds Ovaries fruit Germination depends on :

good time, which is good environment and imbibitions

(absorption)
