At lunch, on the third day of the second Test, India were 338 for three, a lead of 140.
Tendulkar, already the world record-holder for Test hundreds, was 87 not out and Sourav Ganguly, who'd survived a close lbw appeal on five, 53 not out.
The experienced duo's stand was worth 92 after India got through the session without losing a wicket. Tendulkar had faced 191 balls with 11 fours and Ganguly 98 with one six and eight fours.
Tendulkar, who when he'd made 25 became only the third batsman in history to score 11,000 Test runs, resumed on 57 not out with Ganguly unbeaten on four.
England took the new ball as soon as it was available after 80 overs with India having added two runs to their overnight score of 254 for three.
They gave it to Ryan Sidebottom who had an lbw shout against Ganguly rejected by South African umpire Ian Howell.
Chris Tremlett bowled well on Saturday for figures of one for 32 in 20 overs.
But when the 6ft 7in Hampshire quick strayed in length he was glided through the offside for four by Ganguly. And next ball the left-hander hooked his bouncer for six.
James Anderson, who replaced Tremlett, also made the mistake of dropping short and was cut for four by Ganguly.
Sidebottom, however, continued to beat the bat without success during a miserly spell of nine overs for seven runs with six maidens on his Nottinghamshire home ground.
But left-arm spinner Monty Panesar, England's best bowler of recent times, was cover-driven for two fours in three balls by Ganguly during his first over on Sunday.
Tendulkar then went down the pitch to Panesar and drove him high over mid-off for four to go to 84.
Openers Dinesh Karthik (77) and Wasim Jaffer (62), often overshadowed by the middle order, consolidated the advantage India's bowlers had created on Saturday with a first-wicket stand of 147.
Left-arm quick Zaheer Khan took four for 59, his best Test figures against England and leg-spinner Anil Kumble three for 32 as India dismissed England for 198 after Rahul Dravid chose to field first in conditions aiding swing bowling.
