Adaptations Flashcards
Animals and plants must be adapted to their habitats if they are to ______.
Survive
Animals may have special features which help them survive, for instance, different birds have different _______that are adapted for a particular ______.
Beaks
Diet
Behavior of some animals is adapted to their habitat for instance, penguins _____ to keep warm.
Huddle
10 adaptations which camels have:
- Can drink 40 pints of water
- Stomach store 500 pints of water for a short
- It loses little water
- No layer of fat under the skin
- Fat is stored in the hump and can be respired to give ‘metabolic water’.1
- Bushy eyelashes and hair lined nostrils
- Body has a large surface area to volume ratio
- Large feet
- Long legs
- It can withstand an increase in normal body temperature of 9 Degrees Celsius
How do cacti reduce water loss?(6)
- Swollen stems containing water-storage tissue
- Leaves reduced to spines
- Thick waxy cuticle covers the plant’s surfaces and reduces transpiration
- Shallow, spreading root system to quickly absorb any water
- Compact shape, less volume and surface area. So there is less surface area over which water can be lost
- Shiny surfaces-reflect heat and light
How do the leaves carry out photosynthesis if their leaves are reduced to spines?
Their stems are green and contain the chlorophyll that is needed for photosynthesis.
Conifers are also well adapted to withstanding water loss. These trees are often found high up on mountain slopes. Here it can be very windy and normal leaves would easily lose water by _________. Like the cactus, they have a reduced surface area to volume ratio, so there is less surface over which water can be ______.
Transpiration
Lost
Sand Dune plants like ______ have long thin leaves. The leaves are also rolled up along their length. The stomata are found inside the groove formed by the rolled up leaf. Humid air becomes trapped in the groove and so less water vapor passes out of the stomata to be lost to the plant.
