[bhagyavardhan]

Answer 1) (i) Part A is Pollen Grains
(ii) Pollen grains after reaching stigma, they form pollen tube to reach to ovule and do fertilization.
(iii) Part C is pollen tube which helps to transfer to male germ cells present in pollen grains to reach to ovule for fertilization with female cell and polar nuclei.
(iv) The part marked D, is ovary which forms fruit after fertilization.
Answer 2) The path is as follows :
Testes ->Vas deferens -> Seminal Vesicle -> Prostrate gland -> Urethra -> Penis
The seminal vesicle and the prostate glands add their secretions so that the sperm are in a fluid that makes their transport easier, and this fluid also provides nutrition.
After this, it moves to female reproductive system through vagina and then enters Fallopian tube where fertilisation occurs and forms zygote. This moves down to uterus and gets nourishment, to form a new born baby.
Thank you for this wonderful

[harshaks]

Home work question :-

i) Part A is pollen grains
iI) A reaches part B thorough pollen tube
iii) it helps in the transfer of pollen grains from stigma to ovary
iv) Part D will develop as a fruit after fertilisation
Thank you ❤️

[gunguntagore]

1) pollen grain
2)Through pollen tube ( pollination)
3)The style is the tube-like structure that holds up the stigma. The style leads down to the ovary that contains the ovules. Other parts of the flower that are important are the petals and sepals. Petals attract pollinators and are usually the reason why we buy and enjoy flowers.
4)Ovary turn into fruit
AWESOME CLASS👍🏻👍🏻📝

[rithizx]

HW:-
i) Pollen grains
ii) By pollen tube
iii) part c which is the pollen tube, from this pollen tube only the pollen grains reaches ovary, .it it must important for the formation of zygote
iv) it fall off and the new flower will form ❤:)

[sonirai]

A .pollengrain
ii) pollen tube
iii) pollen tube is a passage for male gamete to reach to female gamete or egg
iv) in post fertilization
Sepal, petals shrivel off, ovary become fruit, and ovule became seed

[nikeshmadavi]

Homework Answers:-
Ans 1) (i) pollen grain
(ii) through pollination
(iii) it is the tube which helps in germ cell to reach ovule through ovary
(iv) it is ovary which changes into fruit

Ans 2) path of sperm after ejaculation
Testis → vas deference → seminal vesicles → prostate gland → urethra
Function of gland associated with reproductive system if males :- they provide nutrition to sperm and secrete fluid which gives medium to move for sperms..

[yasharthkesarwani]

Homework Answer:-
Answer.1 (i) A- Pollen grains
(ii) By the formation of pollen tube A (pollen grains) reaches part B.

[charvi]

Homework:
1. (i) 'A' is the pollen grain.
(ii) 'A' reaches be via self or cross pollination.
(iii) 'C' is the pollen tube which facilitates the movement of the male gametes towards the ovary.
(iv) 'D' is the ovary and it will grow rapidly to form the fruit.

2. The path is as follows :
Testes ->Vas deferens -> Seminal Vesicle -> Prostrate gland -> Urethra
The seminal vesicle and the prostate glands add their secretions so that the sperm are in a fluid that makes their transport easier, and this fluid also provides nutrition.
After this, it moves to female reproductive system through vagina and then enters Fallopian tube where fertilisation occurs and forms zygote. This moves down to uterus and gets nourishment, to form a new born baby.

Thank you so much ma'am for the amazing session. And, I love the way you teach.🥰🥰🥰😊😊😊

[charviparkar]

Homework answer
1) A. Pollen grains
B. Through pollen tube
C. It helps in transport of pollen grains consisting of male gamete from stigma to ovary
D. It turns into a fruit after fertilization.
2. The sperm is produced in the testes. Through the vast deferens it reaches the seminal vesicle and prostate glands which provide the sperm liquid called semen for nutrition and smooth tra transportation. It then moves to the urethra which contains urine as well and then is ejaculated into the female reproductive system through the penis. The testes are placed outside the abdominal cavity in a muscular sac called scrotum as they require a lower temperature for the production of sperm cells. A temperature 2 degree Celsius less than the normal body temperature is required. This they are placed outside the body.
Thabk u ma'am for this wonderful session. I have understood this chapter really well now. ❤

[abhinayamadhupada]

Thank you soo much mam you are the best!🙂❤

[mutualyc]

(i) A - Pollen grain containing male gamete.
(ii) Male gamete reaches part B - stigma through a pollen tube that forms after the bursting of pollen grain.
(iii) Part C - Pollen tube provides a way for male gamete to reach out female gamete that is present in ova of the swallowen part so-called ovary in order to fuse and form a fertilised egg called zygote.
(iv) After fertilisation, part - d called ovary gets converted into a fruit over time.

[itsshriyahaah]

Ans1)A is pollen grains
Pollination
C is the pollen tube, helps in movement.

[nasrinansarixc]

1) pollen grains
2)A reaches part B through pollen tube
3) it helps in transport of pollen grains from stigma to ovary
4) After the fertilization the ovary form fruits

[angadsingh]

Finally after asexual reproduction, I completed the chapter with all my might .
Thanks Byjus

[santoshthakur-pcsj]

A) Stigma
2) Through pollen tube
3)helps in the transportation of male gamete
4) the ovule converts into the seeds.
Session was super duper amazing 🤩

[sumangalaganiger]

(¡) pollen grains
(¡¡) by the process of pollination
(¡¡¡) it is the pollen tube which help the pollens to enter into the ovary and then to the ovule where the fertilization take place
(¡v) part D is ovary and after fertilization is over the ovary converts into fruit.

[itsshriyahaah]

Testes-vas deferens--seminal vesicles--prostate gland--urethra.

[zeelpathan]

Hw ans 1 pollen grain
2 through pollen tube by self pollination
3 pollen tune
4 convert in to seed and then future plant ovary fruit

[thanushree]

Mam pls answer this question:
1. A deadly disease is caused by a pathogenic parasite which has flagella as its locomotory organ.
a) Name the organism and the mode of asexual reproduction found in it.
b) How is above mode of reproduction different from the mode of reproduction found in amoeba.
