S1. Ans.(d)
Sol.Fungi (singular: fungus) are a kingdom of usually multicellular eukaryotic organisms that are heterotrophs (cannot make their own food) and have important roles in nutrient cycling in an ecosystem. Fungi reproduce both sexually and asexually, and they also have symbiotic associations with plants and bacteria.
S2. Ans.(a)
Sol. The angiosperms are vascular seed plants in which the ovule (egg) is fertilized and develops into a seed in an enclosed hollow ovary. The ovary itself is usually enclosed in a flower, that part of the angiospermous plant that contains the male or female reproductive organs or both. Fruits are derived from the maturing floral organs of the angiospermous plant and are therefore characteristic of angiosperms.
Gymnosperms: gymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves. 
Pteridophyta :  Pteridophyte are vascular plants i.e., plants with xylem and phloem, that reproduce and disperse via spores.
Bryophyta: Bryophytes are non-vascular, so they do not have the right types of tissues to develop roots, stems, or leaves.
S3. Ans.(b)
Sol. Pteridophytes have naked embryos that are called spores.Phanerogams produce seeds which consists of embryo and stored food. 2. They have well differentiated reproductive tissues which after reproductive process produce seeds.
S4. Ans.(c)
Sol. Lichens are a complex life form that is a symbiotic partnership of two separate organisms, a fungus and an alga. The dominant partner is the fungus, which gives the lichen the majority of its characteristics, from its thallus shape to its fruiting bodies
S5. Ans.(d)
S6. Ans.(c)
S7. Ans.(b)
Sol. During respiration and photosynthesis, gases go in and out of the plants through little holes called stomata using diffusion, not breathing.
S8. Ans.(b)
Sol. Chlorophyll: allows plants to absorb energy from light.
Water:  Water splits into oxygen, hydrogen ions, and electrons to replace the lost electrons of photosystem II in light-dependent reaction. Also, as hydrogen ions pass through ATP synthase, ATP is formed to use in the light-independent reaction.
Carbon dioxide: Carbon dioxide, in its ionic form bicarbonate, has a regulating function in the splitting of water in photosynthesis.
S9. Ans.(c)
S10. Ans.(b)
