Oscars head Isaacs calls for more diversity after row
All 20 contenders in the main acting categories are white and there are no female nominees in the directing or writing categories.
The Academy, which picks the contenders, has faced strong criticism.
But Cheryl Boone Isaacs said she was proud of the nominees and that the body was "making strides" towards diversity.
Ms Boone Isaacs, who is the first African-American president of the Academy, told AP the organisation is "committed to seeking out diversity of voice and opinion''."In the last two years, we've made greater strides than we ever have in the past toward becoming a more diverse and inclusive organisation through admitting new members and more inclusive classes of members,'' she said.
She added she would "love to see" greater diversity among the nominees.
'Selma' snub
After the nominees were announced, people mocked the make-up of the awards using the "OscarsSoWhite" hashtag.There has been much focus on Martin Luther King biopic Selma, with director Ava DuVernay and star David Oyelowo both missing out.
At the Critics' Choice award, another Selma actor, Wendell Pierce, said there would be "amazement" Oyelowo was not nominated once people saw the film.
But Ms Boone Isaacs said acclaim for Selma was reflected in its Best Picture nomination, which is chosen by all the academy members.
She said that while the Academy continued make efforts to become more diverse, the wider industry needed to do the same.
"We hope the film industry will also make strides toward becoming more diverse and inclusive.''
Individual branches of the Academy choose the nominees, with actors choosing the acting categories, for example.
The more than 7,000 members then vote for a winner.
Birdman and The Grand Budapest Hotel lead the race for this year's Oscars with nine nominations each.
