1. Unit 5: Plant Study Guide
Answers

2. The sun- ultimate source of energy
Energy of life- required for growth, reproduction, movement, and transport of materials across membranes
The sun- ultimate source of energy
Photosynthesis- process whereby plants capture energy and make complex molecules
Light reaction
Produces- ATP/NADPH and oxygen
Location- thylakoid membranes
Dark reaction
Produces- glucose
Location- stroma (fluid inside chloroplast)
Role of chlorophyll- absorbs light energy
Source of oxygen- water

3. Interior of stem- composed of vascular tissue (xylem and phloem)
Photosynthesis
Equation: 6CO2 + 6H2O  C6H12O6 + 6O2
Cellular respiration
Equation: C6H12O6 + 6O2  6CO2 + 6H2O
Glycolysis- glucose is split, pyruvic acid is made, some ATP is produced
Fermentation- process where organic molecules are broken down in the absence of oxygen
Electron transport chain of CR- where most of the ATP (energy) is made
Interior of stem- composed of vascular tissue (xylem and phloem)
Plant cells
Collenchyma- specialized for support
Parenchyma- plants soft, primary growth; pliable, thin walled
Sclerenchyma- provides structural support; dead at maturity
Meristems- regions of active cell division; found at tip of stem and root

4. Primary growth- lengthening of plant
Secondary growth- width of plant
Endodermis- regulation of passage of water and minerals into the vascular tissue
Cortex- outermost layer consisting of ground tissue in a stem
Phloem- transports sugar
Xylem- transports water
Mature ovary- fruit of the plant
