Explanation / Answer

15. A pine tree is an example of gymnosperms.

They contain naked seeds in a cone like structure and flowers don’t grow on such trees.

16. All of them are methods of seed dispersal.

Dry, light weight seeds are dispersed through wind, some seeds have attachments such as wings which help them disperse; waterproof seeds near water source get dispersed through water; seeds get dispersed by attaching to animal furs; fruits and vegetable seeds which remain intact when eaten and throughout digestive system, gets excreted intact thus get dispersed with animals.

17. Diatom- A. silica

(Diatoms are algae which consists of cell wall made up of silica)

Amoeba- D. Pseudopodia

(Amoeba contains projections called pseudopodia which help them to move, engulf food etc.)

Volvox- E. green algae

(Volvox is genus of family Volvocaceae. They are green algae and live in fresh water.

Dinoflagellates- B. red tide

(Dinoflagellates are phytoplankton which cause red brown color luminescence on surface of ocean. This is called red tide)

Botulinum- C. bacteria

(Botulinum is a neurotoxin produced by Clostridium botulinum species of bacteria)

18. Stamen is the male part of flower. It consists of anther and filament. Pistil is female part containing stigma, style, ovary and ovule.

19. The most common way by which bacteria derive energy is by chemosynthesis.

20 False

Prokaryotes evolved before eukaryotes. The prokaryotes are simple cells, afterwards eukaryotes evolved which were thought to evolve from prokaryotes.
