আসসালামু আলাইকুম,
আজকে আমি এই পোস্ট এ আপনাদেরকে এসএসসি-২০২১ সালের পরীক্ষার্থীদের দেওয়া বিজ্ঞান বিভাগের জীববিজ্ঞান (Biology) -2 এ্যাসাইনমেন্ট এর প্রশ্ন ও আপনাদেরকে একটি নমুনা উত্তর লিখে দিব।
নমুনা উত্তরটি হুবুহু না লিখে এখান ধারণা নিজেদের মতো করে লিখবেন।
ভুল-ত্রুটি থাকলে ক্ষমা দৃষ্টিতে দেখবেন।
assignment -Analysing
the structure and function of animal cell and animal tissue.
guideline –
Firstly, read page no 33-42 of Biology text book.
Now, observe the list of features.
(No need to include the list in the assignment)
Collect a dice with 1 to 6 number marked as a
probability to get an integer in each throwing. If
dice is not found then total 6 cards could be
prepared with 1-6 marked on them each and could
be used as a dice for lottery.
Dice should roll thrice and that three numbers
found will be considered as a round. As for
example 3, 6 and 4 are rolled. Then no: 3 character
(single layered) from the character list is to be
slected as Character 1 in that round. For Character
2, 3+6=9 no. character (columner) is to be
selected, and for character 3, 9+4=13 no. character
(ciliated) is to be selected. These are to be written
in the particular boxes of the table. Animal tissue
or animal cell containing three characteristics is to
be writen in the box titled ‘Tell who I am’. To fill
up this column, bold letter names should be
selected from particular pages no 33-42 of the text
book.
If animal tissue or cell containing three
characteristics is not available then the dice is to
roll once again and the character is to be noted
roughly in a sheet until the three characters of real
animal tissue or cell are found. For example, if
even after number 9 character there is no
matching, then again the dice has to be rolled, digit
1 is found, and then it is to be observed whether
no:10 character matches with any two of the
previous three characters to form an acceptable
animal tissue or animal cell. In that case, it will be
considered as a round.
If no: 18 crosses in this way, then again counting
will start from character no: 1. e.g., after no: 16 if
the dice rolls 5 then it is 16+5=21. But the
character limit is upto18, so for 21, it will be
considered as no: 3 character after 18.
Such 10 rounds should be played where any
animal tissue or animal cell characteristics must
match and that should be written in the given table.
If more than one is found, it is sufficient to write
only one animal tissue or cell containing three
characters in the box under the column „Tell who I
am’.
Exact similar three characters round should not be
written more than once. Similar character should
not be recognised more than once in a single
round.In that case dice should roll again and
different character needs to be chosen. But in
different rounds, similar character may exist.
Lastly, filled in table is to be submitted as an
assignment.
ধন্যবাদ।
