Q1.Read the following passage and answer the questions given below.
You have seen that buildings are made of bricks. Similarly, the bodies of living organisms are made of tiny units called cells. Cells can be seen only under the microscope. Some organisms are made of only one cell. The cell is enclosed by a thin outer body, called the cell membrane. Most cells have a distinct, centrally located spherical structure called the nucleus. The nucleus is surrounded by a jelly-like substance called cytoplasm. The tiny pores present on the surface of leave. These pores are surrounded by ‘guard cells’. Such pores are called stomata. You often see slimy, green patches in ponds stagnant water bodies. These are generally formed by the growth of organisms called algae. The insect is killed by the juices secreted in the pitcher and its nutrients are absorbed. Such insect- eating plants are called insectivores plants.
(a) What is the function of guard cells of stomata?
(b) Define Cytoplasm.
(c) The tiny openings present on the leaf surface. What are they called?
(d) Name the unit which makes the bodies of living organisms.
(e) Why insectivores plants feed on insects
Answers
a) guard cells are epidermal cells which protect stomata. they close and open stomata. when water is given to plant, guard cell swell up and open stoma( opening of stomata) and when there is bright sun , guard cells close stomata to prevent water loss
b) cytoplasm is the living jelly matrix substance in cell. it is filled inside cell membrane and outside nuclear membrane. it contain all cell organelles . cytoplasm may be thick or thin according to function of cell
c) tiny opening on surface of leaves are called stomata.
d) cells make bodies of living organisms. many cells join to form tissue. tissue of similar function join to form organ. organs form systems which form our body.
e) insectivores plants need certain minerals which are only given by insects. so they are carnivores. these plants feed on insect to survive
hope it helps
