Biology project

One day, Doctor Cell was wandering around Cherry’s body and searching for dead cells to do his research. His research is about human’s cell structures and functions of the inner structures.

Cell Doctor

He's wandering and wandering, and he finally find one. He's ready to cut it. When Doctor Cell cut the dead cell, some liquid comes
out.Doctor Cell felt curious. He immediately went to check
on what is it.

Multiple Select

characteristics and function of cytoplasm

• jelly-like fluid

• contains genetic information

• provides sites for chemical reactions

• allows the movement and transport of materials inside the cell

Doctor Cell understood what cytoplasm is, and he started to check the
thing covering the inner structures of the cell. Doctor Cell felt curious,”Um,
what is the function of it? How does it keep the inner structures stay safe
inside and make sure they won't broken?”

Multiple Select

Functions and characteristics of cell membrane

• double-membrane

• differentially permeable

• thin and flexible

• fully permeable

After knowing the outer structures of the cell, Doctor Cell started to check
on the inner structure of the cell. He picked up a circle-like structure.
Doctor Cell immediately took a look of his Human Cell Structure Book.

Multiple Select

function and characteristics of nucleus

• called nucleus membrane

• carries genetic informations

• called nuclear membrane

• doule membrane

He finally understood what nucleus is, the weird options of the
mc questions in the book made him perplexed. Suddenly, he
saw a question “ mitochondria…” ,Doctor Cell confused again, he never seen this word before. He didn't know what's the look of it and its role in human bodies, so he tried to read the book and do the mc.

Multiple Choice

Characteristic and function of Mitochondria

• double membrane,to control the movement of substances

• double membrane, to generate the energy

• nuclear membrane, to generate energy

• nuclear membrane,to control the movement of substances

While Doctor Cell was reading the book,, a weird cell hit his leg,and it seemed like it doesn’t have a nucleus. “Hmm, what is that. Oh! I remember ! I’ve learnt this before! Let me do a matching question to see whether I still remember the knowledge or not.

Match

Match the following

• prokaryotic cell

• eukaryotic cell

• both prokaryotic and eukaryotic cell

without nucleus

with nucleus

with cell membrane

• without nucleus

• with nucleus

• with cell membrane

Doctor Cell kicked away the prokaryotic cell and continued to take a look of the dead cell, Doctor Cell was searching the lysosomes inside the dead cell, which is responsible for digestion of macromolecules. He checked the book and pondered a mc question about lysosomes.

Multiple Choice

Which of the following statement(s) about Lysosomes is/are wrong?

( i ) some of them are circle in shape

( ii ) it contains enzymes inside

( iii ) it can be found in prokaryotic cells

( iv ) it is called "digestive system " in cells

• only (i)

• only (iv)

• (i),(iii)

• (i),(iii),(iv)

• only (ii)

By doing a different mc question in the book, Doctor Cell finally knew that what’s lysosomes, he also learnt what peroxisome is. As he’s interested in doing different kind of questions about cell, he can’t wait to do another question.

Match

Match the following

• peroxisome

• lysosomes

• cytoskeleton

• nucleus

destruct lipids

destruct the proteins

provide stability and cell movements

store DNA (genetic information)

• destruct lipids

• destruct the proteins

• provide stability and cell movements

• store DNA (genetic information)

After doing the matching questions, Doctor Cell stopped to do the research.
Instead, he took a rest and search for fun facts or funny information of cell
structures.

Fill in the Blanks

Which structure o cel has a nickname --- cell's post office

After relaxing his brain for a while, Doctor Cell went on his research again. He took out the thing with some ribosomes on top of it, and used he little book to learn about that thing again. He noticed that the thing is endoplasmic reticulum, with ribosome is rough endoplasmic reticulum, and the one without ribosomes is smooth endoplasmic reticulum.

Open Ended

State the difference between the structure of smooth ER and rough ER

"Oh yes!"Doctor Cell yelled, he finally finished his research. Apart from cell structures, he also learned some extra knowledge about enzyme. Before going to bed, he did the last question about enzyme in cell structure to ensure fully understood enzyme.

Multiple Choice

Enzymes are typically found in various locations within animal cells, what are they?

(i) Cytoplasm

(ii) Lysosomes

(iii) Endoplasmic Reticulum

(iv) Mitochondria

• only (ii)

• (i),(iii)

• (ii),(iii),(iv)

• all of above

Doctor Cell finally go to bed and taook a rest after the whole long research. His
research helped a lot of Doctor inside Cherry’s body, he had rewarded as the best
doctor in Cherry’s body.
