Cell Biology
What is the function of the mitochondria in a cell?
→ The mitochondria generate energy (ATP) through cellular respiration.
What is the main function of the circulatory system?
→ The circulatory system transports oxygen, nutrients, and waste throughout the body.
When is my bday
16 december
What is DNA, and where is it found in a cell?
→ DNA (Deoxyribonucleic Acid) is found in the nucleus of a cell and carries genetic information.
What is a food chain? Give an example.
→ A food chain shows how energy moves through an ecosystem. Example: Grass → Rabbit → Fox.
Name two differences between plant and animal cells.
→ Plant cells have a cell wall and chloroplasts, while animal cells do not.
Which organ is responsible for filtering waste from the blood?
→ The kidneys filter waste from the blood.
What is my favorite colours
red , blue and purple
What is the difference between asexual and sexual reproduction?
→ Asexual reproduction involves one parent and produces identical offspring, while sexual reproduction involves two parents and genetic variation.
What is the difference between a producer and a consumer?
→ Producers (like plants) make their own food through photosynthesis, while consumers (like animals) eat other organisms for energy.
What is the role of ribosomes in a cell?
→ Ribosomes synthesize proteins.
How does the respiratory system work with the circulatory system to supply oxygen to the body?
→ The lungs supply oxygen to the blood, which is then transported by the circulatory system to the body’s cells.
Which student is my fav
None I like them all equally
What determines an organism’s traits—genes or environment?
→ Both genes and the environment influence an organism’s traits.
How does deforestation affect the environment?
→ Deforestation reduces biodiversity, increases carbon dioxide levels, and contributes to climate change.
What is osmosis, and how does it differ from diffusion?
→ Osmosis is the movement of water across a semi-permeable membrane, while diffusion is the movement of any molecule from high to low concentration.
What type of joint is found in the knee?
→ The knee is a hinge joint.
Who is the first teacher I talk to in school
Sir Kugan
What are chromosomes made of?
→ Chromosomes are made of DNA and proteins.
What is biodiversity, and why is it important?
→ Biodiversity is the variety of living organisms in an ecosystem. It is important for ecological balance and resilience.
What is the function of the nucleus in a eukaryotic cell?
→ The nucleus controls cell activities and contains genetic material (DNA).
What is the function of white blood cells?
→ White blood cells fight infections by attacking pathogens.
What time was I born
3.00 pm
What are dominant and recessive traits?
Dominant traits appear if at least one dominant allele is present, while recessive traits only appear if both alleles are recessive.
How do decomposers benefit an ecosystem?
Decomposers (like fungi and bacteria) break down dead organisms, returning nutrients to the soil.
