Reading from a text file then /grep/output

I have a list of words that I want to grep in many files to see which ones have it and which ones dont.

in the text file I have all the words listed line by line, ex:

list.txt:

check
try this
word1
word2
open space
list ..

I want to grep each line one by one.
like I want it to

grep "check" *.log
grep "try this" *.log
grep "word1" *.log .. etc how can I do this?

and maybe write the output to a file.

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
