Type of plastids responsible for trapping light energy essential for photosynthesis are (A) Leucoplasts (B) Chloroplasts (C) Aleuroplasts (D) Amyloplasts

which type of plastid contains chlorophyll and responsible for photosynthesis?

Type of plastids present in stem tuber of Solanum tuberosum (A) Aleuroplasts (B) Amyloplasts (C) Elaioplasts (D) Chromoplasts

Which of the cell organelles do not contribute to the greenery of a plant? (A) Leucoplasts (B) Chromoplasts (C ) Chloroplasts

In the given statements (i-iv) i) The chlorophyll a is yellow green in colour and chlorophyll b is blue green in colour. ii) Both photosystems absorb more amount of red wavelength. iii) In moderate light, the chloroplasts arrange themselves with their flat surfaces perpendicular to the incident light while during strong illumination, they are parallel to the incident light. iv) The stroma of chloroplast is responsible for trapping the light energy and also for synthesis of ATP and NADPH. Find out the correct statements

Identify the correct statement w.r.t. the given cell A. Concerned with lipid and steroidal hormone synthesis B. Outer non- living rigid structure which gives shape to the cell and protects from mechanical damage and infaction . C. Both lie perpendicular to each other and each has an organisation like the cart wheel . D. Responsible for trapping light energy for the synthesis of sugar. E. Present in cells actively involved in protein synthesis and secretion. F. Spherical structures rich in hydrolytic enzymes.

Assertion : Chloroplasta occur inside the leaves mostly in mesophyll cells along their walls. Reason: The membrane system of chloroplast is responsible for trapping the light energy and also for the synthesis of ATP and NADPH.

Enzymes required for synthesis of carbohydrates and Proteins are present in (A) Mitochondria (B) Chloroplast (C) Centrosome (D) A&B

What type of nuclear reaction is responsible for the liberation of energy : (a) in a nuclear reactor ? (b) in the sun ?

Which of these is wrongly matched ? (a) chloroplasts - chlorophyll (b) elaisplasts - starch (c ) amyloplasts-carbohydrates
