What is the function of the mitochondria?
The mitochondria are the “powerhouse of the cell,” responsible for producing energy through cellular respiration.
Which organelle is responsible for protein synthesis?
The ribosome
What does the nucleus do?
The nucleus controls the cell’s activities and stores DNA.
What is the difference between the smooth and rough endoplasmic reticulum?
The rough ER has ribosomes on its surface and helps synthesize proteins, while the smooth ER synthesizes lipids and detoxifies the cell.
What structure in plant cells is responsible for photosynthesis?
The chloroplast
What is the function of the coarse adjustment knob on a microscope?
t moves the stage up and down to bring the specimen into focus at low magnification.
What magnification do you get when using a 10x ocular lens and a 40x objective lens?
400x magnification.
What is the purpose of the diaphragm on a microscope?
It adjusts the amount of light that reaches the specimen.
Name the part of the microscope where you place the slide.
The stage.
What is the difference between the fine and coarse adjustment knobs?
The fine adjustment knob is used for small, precise focusing, especially at high magnification, while the coarse knob is for larger adjustments.
What are the main stages of the cell cycle
Interphase, mitosis, and cytokinesis.
What happens during interphase?
The cell grows, performs its normal functions, and duplicates its DNA.
List the phases of mitosis in order.
Prophase, metaphase, anaphase, and telophase.
During which phase of mitosis do the chromosomes line up at the center of the cell?
Metaphase
What is cytokinesis?
The division of the cytoplasm, resulting in two separate daughter cells.
What is the function of the cell membrane
It controls what enters and exits the cell while providing protection and support.
Why is it important to start with the lowest power objective lens?
To locate the specimen easily and avoid damaging the slide or lens.
Why is mitosis important?
It ensures growth, repair, and the production of identical daughter cells
