What is the typical plant cell for carrying out photosynthesis?
Leaf palisade cell
1 of 13
Name three adaptations of the leaf palisade cell.
Long, thin cells to form a continuous layer for absorbing light. Numerous chloroplasts that collect light and arrange themselves for maximum yield, large vacuole to push cytoplasm and chloroplasts to cell edge
2 of 13
What is the plant cell wall?
Microfibrils of cellulose polysaccharide, embedded in a matrix for strength
3 of 13
What are the four features of the cell wall?
Made from cellulose microfibrils, connects cytoplasms for exchange, pores called plasmodesmata, middle lamella marks boundary between cells
4 of 13
What are the four functions of the cell wall?
Provides mechanical support for whole prevent and to stop osmotic lysis, for passage of water, and as a carbohydrate store
5 of 13
What is a chloroplast?
Organelle for photosynthesis
6 of 13
What is the function of the chloroplast envelope?
Double plasma membrane surrounding the organelle which is selective for what can enter/exit the cell
7 of 13
What is the grana?
The grana is stacks of up to 100 discs called Thylakoids
8 of 13
What do thylakoids do?
Contain chlorophyll and allow for first stage of photosynthesis
9 of 13
What is the function of the Stroma?
Fluid-filled matrix containing starch grains for 2nd stage of photosynthesis
10 of 13
How is a chloroplast adapted for its function concerning the granal membranes?
Granal membranes with large SA for ordered chlorophyll and enzyme attachment for 1st stage of photosynthesis
11 of 13
How is a chloroplast adapted for its function concerning the stroma?
Stroma fluid contains all enzymes needed to carry out 2nd stage of photosynthesis
12 of 13
How is a chloroplast adapted for its function concerning the chloroplast content?
Contain DNA and ribosomes for fast manufacture of photosynthesis proteins
