cells Flashcards
gene
a segment of DNA that codes for a certain trait
dominant gene
A trait that requires only one allele To be present for that trait to be expressed
Recessive gene
a trait that requires 2 allele to be. Present for that treat to be expressed
cell wall
the outside layer of a plant cell which gives the plants systems and with their stiffness, shape and support
cytoplasm
It contains organelles and cell parts
jelly part of the cell
Mitochondria
They produce the energy currency of the sale and they regulate the cell metabolism
supplies energy
ribosome
makes protein
Endoplasmic reticulum
They full of protein molecules in sacks and transport the synthesize proteins in vesicles to golgi apparatus
can be rough or smooth
surface for chemical activity
Vesicles
They Contain digestive enzymes
Golgi apparatus
stores and releases proteins
vacuole
it is only found in plants
it maintains the proper pressure within plant cells
storage area for various materials
nucleus
stores the cells hereditary material or DNA
control centre of the cell
nuclear envelope
membrane that encloses the nucleus
holds nucleus together
nucleolus
it makes ribosomal from proteins and ribosomal RNA
it plays a vital role in making protein in the cell
spherical body in the nucleus
centrioles
located near the nucleus of animals cells to help organize cell division
looks like little macaroni
