Question

24.
Identify the cell organelle 1 and 2 given below and write about its structure and function.
25. Differentiate between
(a) Plant cell and Animal cell.
(b) Prokaryotic and Eukaryotic cell.
26. (a) Define momentum
(b) A car of mass 1000kg is moving with a velocity of 72 km/h. Find it's momentum.
(OR)
the unlocinetime nranh for a particle moving in fixed direction.​

Answer 1

Answer:

25.

a. Most animal cells are found to be round and irregular in shape. Most plant cells are found to be in fixed rectangular shape. plant cells consists of rigid cell wall where as animal cells don't and animal cells also don't have chloroplast.

b. PROKARYOTIC CELLS: absence of nuclear membrane is known as PROKARYOTIC CELLS.

EUKARYOTIC CELLS : a cell which contains nuclear membrane is known as EUKARYOTIC CELLS.

26.

a. The quantity of motion of a moving body , is measured as product of mass and velocity.

b. may be 7,20,00,000

Explanation:

26.

b. p= m*v

given velocity is in km/h we should change into m/h

now 72km/h will become 72000m/h

then

p=m*v

p=1000*72000

p=7,20,00,000
