question 97
which of the following is not a characteristic of essentially all plants?
a they carry out photosynthesis
b they are heterotrophs
c they are autotrophs
d they are eukaryotes
e they are multicellular organisms

Explanation:

To solve this, we analyze each option:

• Option A: Most plants perform photosynthesis (using chlorophyll to make food), so this is a plant characteristic.
• Option B: Heterotrophs obtain food from other organisms. Plants are autotrophs (make their own food via photosynthesis), so being heterotrophs is not a plant characteristic.
• Option C: Autotrophs (like plants) produce their own food, so this is a plant characteristic.
• Option D: Plants are eukaryotes (have a nucleus and membrane - bound organelles), so this is a plant characteristic.
• Option E: Most plants are multicellular (except some like mosses, but generally, multicellularity is a plant trait).

Answer:

B. They are heterotrophs
