4.01 Explain the growth process of plants
Photosynthesis
1. The food manufacturing process in green plant that combine carbon dioxide and water in the presence of light to make sugar and oxygen.
Photosynthesis
6 CO2 + 6 H2O --- C6H12O6+ 6 O2 Carbon dioxide + Water + Light energy--- Glucose + Oxygen
Moisture
90% of plant tissue is made of mostly water Water carries nutrients throughout the plant
Hardiness Zones
Charlotte is zone 7.
Stages of plant growth
Dormant is when plants rest or grows very little.
Stages of plant growth
Juvenile is when plants first start to grow from a seed
Light
Long day plants require short nights to flower. Examples are African violets and spinach.
Hardiness Zones
North Carolina is zones 6-8.
Light
Photoperiodism is the response of plants to different amounts of light regarding their flowering and reproduction cycles.
Light
Phototropism is the tendancy for plants to grow toward a light source.
Hardiness Zones
Plants are categorized by zones based on the average minimum temperature.
Stages of plant growth
Reproductive is when plants produce flowers, seeds and fruit.
Light
Short day plants require long nights to flower. Examples are poinsettia and azalea.
Photosynthesis
The by-product of photosynthesis is oxygen.
Photosynthesis
The main product of photosynthesis is sugar.
Reproduction
The plant process that increases plant numbers usually from seeds.
Translocation
The process by which food moves within a plant from one plant part to another. The process by which nutrients move within a plant from one plant part to another.
Osmosis
The process by which minerals enter the plant through cell walls. The process by which water enters the plant through cell walls.
Absorption
The process by which plant roots take in water The process by which plant roots take in air.
Transpiration
The process by which plants lose water from their leaves through evaporation Transpiration also occurs in the stems
Respiration
The process through which plant leaves, stems and roots consume oxygen and give off carbon dioxide. Plants produce much more oxygen through photosynthesis than they use through respiration.
Reproduction
The two main methods of reproduction are sexual and asexual.
Stages of plant growth
Vegetative is the second stage of growth that begins after the plant begins photosynthesis and actively grows leaves, stems, and roots prior to flowering
