life cycle of flowering plants

Question 1

life cycle of flowering plants are…

Answer 1

double feritilization

Question 2

pistil

Answer 2

female part of flowering plant

Question 3

petals

Answer 3

attracts

Question 4

ovule

Answer 4

inside ovary

Question 5

stigma

Answer 5

sticky top, stickly because need to attract pollen grain

Question 6

anther

Answer 6

produce pollne

Question 7

inside the ovule

Answer 7

two polar, haploid d bodies and haploid egg

Question 8

ovary

Answer 8

when it become bigger = fruit,

Question 9

ripened ovary fruits

Answer 9

cucumber, avocado

Question 10

ovule then,…..

Answer 10

becomes a seed, if only one ovule = only one seed produced, if many ovule = many seeds produced

Question 11

inside the pollen

Answer 11

generative nucleus and tube nucleus (both are haploid),

Question 12

the tuble nuclues

Answer 12

creates a pollen tube, at the head of pollen tube = tube nucleus, pollen goes al the way down the style to the ovary and enter through the base of the ovule,

Question 13

double feritilization

Answer 13

to feritilization with two sperms

Question 14

purpose of the tube nucleus

Answer 14

get sperm to egg

Question 15

gene

Answer 15

divides by mitosis and create two sperm cells, occurs early in pollen tube

Question 16

double fertilization process

Answer 16

sperm move to the ovule, one sperm joins with egg and create diploid zygote, zyote crate embryo plant, the second sperm join with two polar bodies and form 3n zygote, that zyote produce triploid endosperm

Question 17

zygote from first sperm

Answer 17

do mitotisis, creat embryo plant

Question 18

zyogte from second sperm

Answer 18

divid in mitosis and produce triploid endosperm

Question 19

triploid

Answer 19

three sets of chroosomes

Question 20

endosperm

Answer 20

purpose is to protect and nourish the embryo, anayloug to yoke of egg
