eukaryotic cell structure

?
Nucleus - structure
surrounded by double membrane with pores and contains nucleolus with RNA
1 of 26
nucleus - function
is the control centre of the cell, transmits genetic information and stores organisms genome
2 of 26
rough ER - structure
coated with ribosomes, system of cisternae
3 of 26
rough ER - function
assembles amino acids into protein and is transferred to golgi for modification
4 of 26
Smooth ER - structure
system of cisternae with no ribosomes
5 of 26
smooth ER - function
contains enzymes that synthesis lipids like, cholesterol, lipids and hormones
6 of 26
Golgi apparatus - structure
vesicles bring materials to and from the golgi apparatus
7 of 26
golgi apparatus - function
proteins are modified and then sent off in vesicles to the cell or outside of the cell
8 of 26
mitochondria - structure
inner membrane is folded into cristae and the inner part if a matrix filled with fluid
9 of 26
mitochondria - function
site of aerobic respiration and the site of ATP synthesis
10 of 26
chloroplast - structure
double membrane, stacks of thykaloids to form grana
11 of 26
chloroplast - function
site of photosynthesis, convert solar energy to chemical energy
12 of 26
vacuole - structure
sacks containing cell sap
13 of 26
vacuole - function
keeps cell turgid
14 of 26
lysosomes - structure
contains powerful enzymes
15 of 26
lysosome - function
digest dead cells and return nutrients
16 of 26
cilia and undulipodia - structure
contains microtubles formed form centrioles
17 of 26
cilia and undulipodia - function
cilia have receptors and sensors, undulipodia allow sperm to propel
18 of 26
ribosomes - structure
made in nucleolus
19 of 26
ribosomes - function
synthesises proteins for export
20 of 26
centrioles - structure
two microtubules at right angles
21 of 26
centrioles - function
make cilia and microtubules
22 of 26
cytoskeleton - structure
a network of different proteins
23 of 26
cytoskeleton - function
microtubules provide support to cells and facilitates movement for motor proteins
24 of 26
cellulose cell wall - structure
made from bundles of cellulose fibres
25 of 26
cellulose cell wall -function
maintains cell shape and causes the cell to stay turgid
