(45 cards)
what is the role of golgi apparatus
processes and packages lipids and carbohydrates
makes lysosomes
features of a golgi apparatus
cisternae - fluid filled sacs
vesicles - small hollow structures
functions of mitochandria
site of aerobic respiration producing ATP
features of mitochandria
-double membrane controls entrance and exit of molecules in and out
- cristae - large SA
- matrix , contains enzymes involving respiration
functions of rough endoplasmic reticulum
-synthesis of proteins
-provides a pathway for materials to be transported throughout the cell
features of rough endoplasmic reticulum
- system of membranes enclosing a fluid space
- ribosomes on outer surface
functions of lysosomes
- breaks down material ingested by a phagocyte
- releases enzymes to destroy material outside the cell
- digests worn at organelles
features of lysosomes
- double membrane
- contains emzymes
what are the two parts that make up the nucleus
nucleolus
nuclear membrane `
what are the functions of the nucleus
- acts as a control for the cell
- produces mRNA
- contains chromosomes, manufactures RNA and ribosomes
features of the nucleus
- nuclear envelope
- double membrane
- nuclear pores allows mRNA
- chromatin
- nucleoplasm jelly
- nucleolus makes mRNA and ribosomes
what are vesicles
transports proteins around the cell
what is a cytoskeleton
a series of protein threads that runs through the cytoplasm
what are the functions of the cytoskeleton
- provides support and structure to the cell
- transports organelles and materials within
- causes a cell to move
what are the 3 parts to the cytoskeleton
- microfilaments
-microtubules - intermediate fibres
what are microfilaments
helps with cell movement, cell contraction
what are microtubules
determines the shape of the cell
and movement of organelles
what are intermediate fibres
strength ad support of the cell
what are specific microtubules
centrioles are microtubules involved in creating and organising spindle fibres
what is flagella
moves the cell
what are cilia and how do they help the cell
surface of the cell
moves objects adjacent to the cell
what is the plant cell wall
- made of celulose
- supports the plant and protects it from pathogens
what are vacuoles
maintain the turgor of the plant
what is the membrane of the vacuole called
tonoplast
