In tropica!rain- forests, the canopy is thick and shorter plants growing below it, receive filtered light. How are they able to carry out photosynthesis ?

Short plants growing under the thick canopy of a rainforest receive filtered light but still perform photosynthesis. Explain.

Photosynthetic organisms occur at different depths in the ocean. Do they receive qualitatively and' quantitatively the same light? How do they adapt to carry out photosynthesis under these conditions?

Read the paragraph and answer the questions given below : Reproduction is the process by which the living Species continues its existence. Lower organisms carry out asexual reproduction while higher plants and animals always show sexual reproduction. Plants reproduce asexually by methods such as fragmentation, vegetative propagation, budding, Spore formation. For sexual reproduction they form gametes. In animal kingdom, budding, fission of different types and parthenogenesis are some of the methods that do not require both the sexes. Though regeneration also forms new individual, it is not considered to be a reproductive process because. basically it is a repair process. The ability to regenerate is lost in higher phyla. In human beings it is restricted only to wound healing. Sexual reproduction is also undergoing lots of experimentation such as cloning which may make females capable of producing their own baby without intervention of any male. Answer the follolwing question. How do living species continue their existence?
