because they dont need to get as much sunlight
None! Cacti grow spines instead of leaves.
These plants grow in shady places have broad leaves because in shady places there is less amount of light and broad leaves can absorb maximum amount of light.....
Scale like leaves
Cacti :D
Conifer trees grow needles and cones
Spines have replaced leaves on cacti.
Leaves have evolved into spines on the cactus.
Plants may become toxic, poisonous or distasteful to grazing animals. Some plants develop sharp spines or thorns. The holly, for instance, has spines round the edge of leaves that grow low down, while the leaves near the top may be spineless.
spines
The ocotillo plant is a common desert plant found in the southwestern United States and Mexico that has thorns but is without leaves. It is known for its long, vertical stems covered in sharp spines, which help reduce water loss and protect the plant from herbivores. The plant produces leaves only after a rainfall to maximize its photosynthetic potential.
Can be used for rainsticks. The spines are pushed to the inside of the hollow cactus and shells are put in making the sound of rain when inverted. Spines pushed in so the shells don't fall too fast.
how the spines on an octopus tree help the plant's leaves keep the water they need?
