why do some plants have leaves that are shaped like sharp needles?
a to help the plant climb

b to store more water

c to capture more sunlight

d to keep animals away and reduce water loss

Explanation:

• Option A: Leaves shaped as needles don't help climbing; structures like tendrils do. Eliminate A.
• Option B: Needle - shaped leaves aren't for water storage; succulent stems/leaves (e.g., cacti) store water. Eliminate B.
• Option C: Needle - shaped leaves have a smaller surface area, so they don't capture more sunlight than broad leaves. Eliminate C.
• Option D: Sharp needles can deter animals from eating the plant. Also, the small surface area of needle - shaped leaves reduces water loss (transpiration), which is beneficial in dry or cold environments (e.g., conifers). This option fits.

Answer:

D. To keep animals away and reduce water loss
