Movement- Movement of the stem in order to try and catch the light of the sun.

Respiration-

DARK: Respiration, no photosynthesis
Oxygen taken in and CO2 given out

DIM LIGHT: Photosynthesis and respiration are equal
Neither gas is taken in or given out

BRIGHT LIGHT: Photosynthesis rate is greater than the respiration rate
CO2 is taken in but Oxygen is given out.

glucose + oxygen → carbon dioxide + water (+ energy)

Sensitivity- Sensing changes in the environment

Plants sense the position of the sun and move towards it

Homeostasis- Maintenance of a constant temperature

Plants control themselves with water; by cooling with respiration and by going dormant when it gets too cold. Evergreens are the few plants that don't do that. They keep going year round; usually because they live in cold climates.

Reproduction- the fertilization of the seed in plants

Excretion-
1. The gaseous wastes, oxygen, carbon dioxide and water vapour are removed through stomata of leaves and lenticels of stems.

2. Some waste products collect in the leaves and bark of trees. When the leaves and bark are shed, the wastes are eliminated.

3. Some waste products are rendered harmless and then stored in the plant body as solid bodies. Raphides, tannins, resins, gum, rubber and essential oils are some such wastes.
