cells- how are they structured to perform functions

cell membrane function

controls the movement of substances in and out of the cell

nucleus function

controls the activities of the cell and stores genetic material (dna)

mitochondria function

carry out aerobic respiration to release energy that the cell can use

chloroplast function

absorbs light to make sugar in photosynthesis. contains chlorophyll

plasmids function

carry additional genetic information (dna)

how is the nucleus structured to perform it’s function?

it contains genetic information (DNA) which provides instructions for the cell.

how is the cell membrane structured to perform it’s function?

selectively permeable, allowing some substances through while restricting others.

how are mitochondria structured to perform their function?

has a folded inner membrane, providing a large surface area for reactions involved in respiration

how are chloroplasts structured to perform their function?

they contain chlorophyll which absorbs light energy needed for photosynthesis.

how are plasmids structured to perform their function?

the circular dna contains extra genetic information that can help bacteria survive
