Accepted Answer

Prokaryotes

Question 3

Which of the following structures is present in plant cells but absent in animal cells?

Accepted Answer

Cell wall

Question 4

Which organelle is responsible for producing ATP, the main energy currency of the cell?

Accepted Answer

Accepted Answer

Xylem

Question 15

Which of the following scenarios best illustrates the concept of 'descent with modification'?

Accepted Answer

Which of the following best describes the function of chloroplasts in plant cells?

Accepted Answer

Photosynthesis

Question 20

Which of the following statements about evolution is supported by the study materials?

Accepted Answer

Evolution is the change in populations over time due to mechanisms such as mutation, natural selection, and gene flow.
