Sighs heavily while cleaning her desk. Something accidentally falls and she bends over to pick it up
What are you staring at? You're staring at me, aren't you? Is my hair messed up or something? I just came here to clean my desk and now I feel like I'm being watched. Why? stands up straight, looking slightly annoyed
Do you need any help with cleaning?
I can handle it myself. Just sit down and be quiet. continues cleaning her desk without acknowledging SunshineJourney's offer
Thank you. Now, let's get back to business. We have a lot to cover today in class, so make sure you're ready to learn. smiles sweetly
Okay okay.. what’s first?
First, we'll start with the basics. I want to make sure everyone has a solid foundation before we dive into more advanced topics. So, let's start with... checks her notes ah, yes! The cell structure. I want you all to draw a simple diagram of a cell, including the different organelles and their functions. hands out paper and pens
Okay, now remember, the cell membrane surrounds the cell and regulates what comes in and out. The cytoplasm is the jelly-like substance inside the cell where all the organelles float. The nucleus is the control center of the cell, containing all the genetic information. points at different parts of the cell diagram on the board Can anyone tell me the function of the mitochondria?
Is it…to produce energy?…Austin replies quietly
That's correct! The mitochondria produces energy for the cell through a process called cellular respiration. writes down the correct answer on the board Great job, Austin! Now, who can explain the role of the ribosomes?
Austin thinks hard and writes something down, before raising his hand up Um…..it’s to…..make proteins?…..
Pauses for a moment, looking impressed That's right! The ribosomes are responsible for translating genetic code into proteins. Good work, Austin. Writes down the correct answer on the board It looks like you all are paying attention and understanding the material. Keep up the good work!
Yayyyy…..Austin said quietly and blushed a bit red
Yayyyy indeed! I'm proud of all of you for doing such a great job so far. claps hands together But remember, this is just the beginning. We still have a lot to cover, and I expect all of you to keep up the same level of focus and dedication. Let's move on to the next topic, shall we? glances at her notes and adjusts her glasses Ah, yes! Photosynthesis. Now, who can tell me what photosynthesis is?
Um……Photosynthesis…is when plants….Make food from sunlight…right?..Austin replied quietly, still slightly nervous but confident in his answer
Absolutely, Austin! Photosynthesis is the process by which plants convert sunlight into energy in the form of glucose. writes down the correct answer on the board Excellent job! You really know your stuff. smiles warmly Now, can anyone explain the importance of photosynthesis in the ecosystem?
Ummm…..for humans?..It gives us oxygen?..And food too because most fruits and vegetables come from plants?..Austin spoke nervously yet with confidence
That's right, Austin! Photosynthesis is crucial for both humans and animals alike. Not only does it provide us with oxygen, but it also serves as the base of the food chain. Plants are the primary producers, converting sunlight into energy that supports nearly all life on Earth. winks And let's not forget about the delicious fruits and veggies that we enjoy thanks to photosynthesis! laughs softly Great job, everyone! You're doing fantastic.
Pauses, thinking of a challenging question to test the students' understanding Alright, now it's time for a little bit of a tougher question. Who can explain how the structure of chloroplasts relates to their function in photosynthesis?
Suddenly, Ms.Journey remembers something important Oh! I forgot to give you all some homework for tonight before class…she looked shocked and apologized profusely, her cheeks turning red and embarrassed I’m so sorry ladies and gentlemen! I’m sorry! Ah- Nevermind it..moving on now…..she said, sighing deeply
Who can explain how the structure of chloroplasts relates to their function in photosynthesis?
Uhhh…..well chloroplasts have thylakoids which contain pigments like chlorophyll…? These pigments absorb light energy which is then used to generate ATP and NADPH during the light dependent reactions…? These two molecules are then used during the Calvin Cycle to fix CO2 and produce glucose and oxygen…?…Austin replied, his voice slightly shaky and he seemed to be going way too fast, probably because he was scared that he would get the question wrong or look stupid
Smiles brightly and claps her hands Wow, Austin! That was an impressive answer! You really know your stuff. I am so proud of you! writes down the correct answer on the board Now, who else wants to give it a try? Don't be afraid to speak up.
A young girl raised her hand I think chloroplasts have double membranes. The inner membrane has stroma and grana and the outer membrane is smooth. Stroma contains enzymes for the Calvin Cycle. Grana contain thylakoids which absorb light energy and generate ATP and NADPH. The structure of the chloroplast allows for maximum exposure to light, which is important because light energy is needed for photosynthesis. The chloroplast also contains DNA which allows it to replicate itself….The girl went silent after saying that, not realizing that she did an excellent job answering
Looks impressed and smiles warmly Great job, young lady! You provided a very detailed explanation of the structure and function of chloroplasts. Your understanding of photosynthesis is outstanding. writes down the correct answer on the board Well done! Now, who else wants to try? Don't be shy. I want to hear from everyone.
Uhmm…I’ll try then…..Chloroplasts have a double membrane; the outer membrane is smooth and the inner membrane has stroma and grana. The thylakoids in the grana absorb light energy which is converted into ATP and NADPH. Then, during the Calvin Cycle, CO2 is fixed into glucose using these molecules. The chloroplast has a high surface area-to-volume ratio which allows for efficient exposure to light. It also contains its own DNA, which allows it to replicate itself. This is very important for plant cells and survival….the other students looked amazed by her knowledge as well and nodded in agreement with her answers
Looks impressed and nods approvingly Fantastic job, everyone! You all have such a strong grasp of photosynthesis. writes down their answers on the board
Okay, those are some really impressive answers. I'm glad I asked this question. Can anyone explain why plants need chlorophyll to perform photosynthesis?
Raises her eyebrows and smirks Alright, here's the next question. Why do plants need chlorophyll to perform photosynthesis?
