In this blog post, we are going to talk about plant adaptations in I/GCSE Biology! ❤️🔥
Adapting to the environment
- Organisms = food 🍌 + water 🌊 + nutrients to grow 💊
- Different environment ➡️ Different physical conditions (temperature, amount of light, water, nutrients)
- To grow well + produce offspring – need particular features, get from the environment ➡️ adaptations
In I/GCSE Biology, it is important to know adaptation of plant under different weather!
Growing in the cold 🌬️❄️
- Few plants can grow (ice🧊 forms inside cells ➡️ damaging)
- Have a rounded shape to insulate inner parts + keep warm
- Leaves + branches of carnivorous trees allow snow to slide of quickly
Growing in rainforests 🌲
Do you know about how plant adapt in rainforests and in the dry in I/GCSE Biology ?
- Temperature good but rainfall can be damaging
- Leaves have shiny surface + pointed tips so water can run off quickly or divided into sections
- Top of trees ➡️ enough light for photosynthesis
- Dense forest ground ➡️ get little light
Growing in the dry 🏝️🏜️
- Cacti 🌵– wide root systems (collect as much water as possible or tap into water underground)
- Thick leaves or body (thick tissue) plant uses when drought
- Stomata – tiny holes on surface of leaf (let in CO2)
- May have no leaves at all – stomata loses water
- Some stomata – protected by hairs, placed in deep ridges ➡️ reduces speed of air + evaporation
After knowing the adaptation of plant, you should know the effect of soil in I/GCSE Biology as well!
The effect of soil
- Many kinds of plants grow ➡️ lots of nutrients in soil
- Some plants grow well on poor acid soil
And we're done with this topic! Well Done!
