There are 130 fern samples did the biologist collect.
What is fern and moss samples?
In contrast to ferns, which are vascular plants, mosses are nonvascular primitive plants that produce spores. Furthermore, unlike ferns, which have a plant body that is divided into real stems, leaves, and roots, mosses have none of these features. Ferns also have circinate vernation, which is not true of mosses.
Given:
A biologist collected 326 fern and moss samples. there were 66 fewer ferns than moss samples.
Let, f denotes the number of ferns collected and
m denotes the number of mosses collected
From the given information,
m + f = 326 ..(1)
m - 66 = f ..(2)
Plug equation (2) in equation (1),
m + m - 66 = 326
2m = 326 + 66
2m = 392
m = 196
Plug m = 196 in equation (2),
f = 196 - 66
f = 130
Hence, there are 130 fern samples did the biologist collect.
