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

Light

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
