Necessity of Support and Movement of Plants and Animals
Importance of movement to Plants
- Enhance fertilisation, when gametes fuse or pollen tube germinates.
- Enables plants to obtain resources from the environment like water, light and nutrients.
- Enables plants escape or avoid harmful stimuli like high temperature.
Importance of locomotion to Animals
- Searching for food, mates and shelter.
- Escaping danger or unfavourable environmental conditions.
Importance of Support to Plants
- Exposure of leaves to sunlight and CO2 for photosynthesis.
- Exposure of flowers to agents of pollination.
- Exposure of fruits and seeds to agents of dispersal.
- Enables plants to withstand forces such as wind and gravity that might cause breakage.
Importance of Support to Animals
- Allows for muscle attachment necessary for locomotion.
- Support framework protects delicate organs.
