Biology quiz 1

cell structure

cell membrane

outside layers of the cell and chooses what goes in and out.

nucleus

Contains DNA which gives instruction to the cell and controls/determines its function.

Nuclear envelope

the membrane that separates the DNA from the rest of the cell. controls what enters and exits the Nucleus.

Smooth endoplasmic reticulum

the membrane structure close to the nucleus that produces lipids.

rough endoplasmic reticulum

the membrane structure close to the nucleus that produces protein for export.

ribosomes

structure which is free floating to the rough ER which is responsible for producing protein.

golgi body

the sacs close to the cell membrane responsible for packaging the products made by the cell for export.

mitochondria

the organelle responsible for cellular respiration producing ATP which is the molecule used to provide energy for chemical reactions in the cell.

lysosome

a membrane bound sac that contains digestive enzymes. It merges with other vacuoles/ vesicles to break down nutrient molecules or it breaks down other organelles that are old and damaged.

vacuole

a membrane bound sac that contains material for the cell to use or to be exported out of a cell.

vesicle

a very small membrane bound sac that contains material for the cell to use or to export out of a cell.

chloroplast

an organelle that contain chlorophyll. It is found in plants and is responsible or photosynthesis a process that allows the plant to convert sunlight and CO2 into sugar and oxygen.

cell wall

the cellulose material that surrounds the plant cell to give it structure and support so that the cell can stand up.

flagella

the tail or tails at the end of the cell responsible for helping the cell move.

cilia

the hair like structure around a cell that enables it to move

Nucleolus

the dark structure inside the nucleus responsible for making ribosomes.

centrosome

the structure that enables the spindle fibers to anchor and pull the chromosomes apart.

centriole

the structure that makes the centrosome.

Deoxyribonucleic acid (DNA)

Store and transmit genetic transformation.

which is plant, which is animal?

Left is plant because it has chloroplast and cell wall and right is animal because it has centrioles.

What does ACGT stand for and which goes with eachother

A=adeni C= cytosine G= guanine T= thymine. RELATIONS AT CG

What is happening during G1

G1 i used for the cell getting ready to replicate DNA

What’s happening during S and what’s it stand for

S stands for synthesis and it is when the cell is replicating DNA

What is happening during G2

G2 is when the cell is getting ready for cell division
